The 4th International Rain Enhancement Forum (IREF) that brought together leading experts, scientists and researchers from all over the world was held in Abu Dhabi this past week. It was about the latest research and innovation in rain enhancement science together with possible collaborations to address the challenge of global water stress. The Future direction of rain enhancement research reviewed was reported on by all local media.
Emirates News Agency (WAM) — 25 January 2020
The UAE Research Program for Rain Enhancement Science, UAEREP, hosted a workshop to update its solicitation document, which will define the future calls for research proposal submissions. The workshop built on the productive discussions that took place during the 4th International Rain Enhancement Forum and its various plenary sessions.
UAEREP organised the 4th International Rain Enhancement Forum from 19 to 21 January 2020 under the supervision of the National Center of Meteorology. The event convened prominent national and international experts, researchers, scientists, and stakeholders to highlight the latest scientific and technological advancements in rain enhancement.
The full-day event brought together leading scientists and experts in atmospheric research and technologies, and centered around two main themes: ‘Cloud to Ground Science: Identifying Knowledge Gaps’ and ‘New Approaches and Technologies for Rain Enhancement’.
The session opened with a welcome speech by Alya Al Mazroui, Director of UAEREP, who outlined the programme’s purpose and ambitions.
Alya Al Mazroui said: “This workshop follows the successful fourth edition of the International Rain Enhancement Forum and the productive discussions we had over the course of the three days of intensive sessions and the Town Hall Meeting. The workshop is crucially important for our call for new research proposals and the shaping of the future direction of UAEREP’s research objectives.”
She added: “As we move forward with our efforts to enhance collaboration and seek viable solutions for global water stress, it is essential to build stakeholder consensus around our research goals and priorities to ensure the relevance and quality of proposals for the future of the our research program.”
Al Mazroui also revealed that the content of the new solicitation document will be shared publicly in mid-2020 as part of the call for research proposal submissions for the Program’s 4th cycle starting in 2021.
Participants at the workshop were provided with a detailed overview of UAEREP’s previous solicitation and management plan and the workshop structure by Dr. Richard Behnke, chair of UAEREP’s international reviewers committee.
In his presentation, Dr. Deon Terblanche, Weather and Climate Consultant at World Bank and former Director of Research at the World Meteorological Organization (WMO), highlighted the achievements and challenges of past UAEREP awardees, and the latest advances in precipitation enhancement research.
Dr. Deon Terblanche also chaired a session titled ‘Cloud to Ground Science: Identifying Knowledge Gaps’, covering key topics such as quantifying the evaporative loss between cloud-base and the surface, improving areal precipitation estimation through a combination of remote sense and ground-based measurements, and translating seeding effects on single storms into areal effects. Panelists also discussed inter-cloud interactions in a convective environment, rainfall-runoff-groundwater relationship and the impact of cloud seeding and environmental and ecological changes due to long-term cloud seeding.
The workshop also facilitated productive discussions around ‘New Approaches and Technologies for Rain Enhancement’. Chaired by Dr. Steve Griffiths, Senior Vice President for Research and Development at Khalifa University, the session provided an insight into the technologies for observing physical phenomena, data modeling, analysis, and evaluation and experimental design, technologies, and instrumentation.
Summarising workshop outputs, Dr. Robert Robinson, co-chair of the committee, outlined the key takeaways and observations from the workshop participants.
The outcomes of the IREF town hall meeting, which took place on 21 January under the theme of “Determining Future Directions for Rain Enhancement Research”, provided important input for the discussions during the workshop, and for the shaping of the new UAEREP solicitation and the research proposal calls.
Solar deployment continued to pick up in the Middle East and North Africa in 2019, the Middle East Solar Industry Association has said in its annual report. Brian PUBLICOVER in a PV magazine article titled ‘Solar is gaining traction in MENA region – but plenty of obstacles remain’ and dated January 17, 2020, explains the whereabouts of such deployment.
The Middle East Solar Industry Association (MESIA) says energy investment in the Middle East and North Africa (MENA) region could hit $1 trillion in the 2019-23 period.
The organization cited statistics from consultancy Frost & Sullivan valuing the region’s operational PV capacity at $5-7.5 billion, with an additional $15-20 billion worth of projects set to come online by 2024.
However, policymakers in many countries are still struggling to find the right mix of legislation, technology, financing and procurement options to kick-start development, the region’s top solar industry group said in its Solar Outlook Report 2020.
MESIA noted a large gap among the region’s varied PV markets in terms of cumulative installations and development. Egypt, Jordan, Morocco and the United Arab Emirates lead on deployment with Saudi Arabia soon to swell their ranks. While a handful of countries including Pakistan and Iraq are struggling to bring more solar online, markets such as Tunisia, Kuwait and Oman are starting to add significant projects to the regional PV pipeline, said the association.
Regional policymakers are increasingly prioritizing distributed solar, led by Dubai. The most populous city in the United Arab Emirates launched its Shams Dubai program in 2015 to support residential PV and commercial and industrial solar installation. By October, Dubai had installed around 125 MW of distributed PV capacity at 1,354 sites, MESIA said.
The industry association also highlighted the important role played by the Dubai Electricity and Water Authority in getting commercial and industrial projects built, noting market drivers for the segment vary across the MENA region. Cuts to electricity tariffs in markets such as the UAE, Jordan, Oman and Saudi Arabia have played a role, backed by the establishment of supportive regulatory frameworks, particularly for wheeling and net metering, the regional body said.
The Egyptian authorities made significant progress on the massive Benban solar complex last year. Roughly 1.47 GW of solar capacity – including a wealth of bifacial and tracking projects – was commissioned at Benban by the end of November, MESIA said. The $4 billion, 1.8 GW complex will eventually feature 41 projects.
The Egyptian government wants renewable energy to account for 20% of its electricity mix by 2022, and 42% by 2035, including 52 GW of large scale and distributed-generation projects. It continues to look beyond feed-in tariffs with the Egyptian Electricity Transmission Co (EETC) and World Bank private sector arm the International Finance Corporation signing a deal in April to fund projects chosen via auctions, for example. The EETC signed a solar power purchase agreement with Saudi’s ACWA Power in October for the 200 MW Kom Ombo project, at a price of $0.0275/kWh. Construction is expected to wrap up in the first quarter of next year.
However, Egyptian energy demand is set to leap from 27.6 GW last year to 67 GW by 2030, MESIA said, citing Frost & Sullivan data. To facilitate renewables deployment, the country will need a competitive electricity market and will have to scrap subsidies for fuel and electricity tariffs dating back to 2016 while also facilitating the development of energy storage to support distributed PV roll-out, the industry group argued.
United Arab Emirates
MESIA describes the UAE as a regional “front runner” for PV and it made undeniable progress last year. Having launched commercial operations at the 1,177 MW Sweihan PV project, Abu Dhabi in November the allocated the fifth, 900 MW phase of the massive, 5 GW Mohammad bin Rashid Al Maktoum Solar Park for a record low power price of $0.01693/kWh. The solar park’s installed capacity currently hovers around the 713 MW range, MESIA said, noting the third to fifth stages of the project will be finished in the years ahead, with full completion scheduled for 2030.
The future also looks bright for solar in the wider UAE, particularly at utility scale. In November, the Emirates Water and Electricity Co closed submissions from developers for a 2 GW solar project at Al Dhafra. That project is set for completion by the first quarter of 2022.
MESIA said it expects a similarly sized tender early this year, as Abu Dhabi may be gearing up to install another 6 GW of solar by 2026. However, PV will have to compete with nuclear and rival renewables in future. With more intermittent renewables capacity coming online, MESIA expects the UAE authorities to start to include more energy storage capacity in future PV tenders.
MESIA said energy storage will be “pivotal” to the development of Jordan’s solar sector. The country has been developing storage capacity for a while, as it is struggling to stabilize its electrical transmission network while it brings significant amounts of large scale solar and wind capacity online.
“At this stage, Jordan’s capability to strengthen the grid, commitment to achieve increased energy efficiency and develop additional storage is key for the future market attractiveness,” the industry association reported.
The authorities launched a tender last year for a study on the feasibility of installing 30 MW of pumped storage capacity at the nation’s key dams, MESIA noted.
Saudi Arabia’s growing PV market continues to move from strength to strength, according to the association, which highlighted the 300 MW Sakaka PV plant – the kingdom’s biggest to date. The regional body also noted the Renewable Energy Project Development Office asked 60 pre-qualified companies to submit bids for “six solar energy schemes with a combined capacity of 1.5 GW” late last year, in addition to six projects the authorities started tendering this month.
However, while the country remains one of the most promising regional PV markets, the Saudi authorities still need to tackle key challenges, MESIA said. The government must collaborate more effectively with the private sector, among other things. It also needs to improve the regulatory environment and propose new business models to unlock the potential of its fledgling commercial and industrial solar sector, the industry group said.
MESIA sees Tunisia’s commercial and industrial solar segment as particularly promising but noted the market continues to struggle in the face of fossil fuel subsidies. The regional body argued the Tunisian government must introduce incentives such as tax breaks to encourage greater investment in commercial and industrial PV, among other policy considerations.
MESIA also noted the Tunisian authorities have overseen critical investments in grid infrastructure upgrades over the past year, in anticipation of $2 billion of anticipated foreign investment in the solar and wind sectors over the next three years. The Tunisian Ministry of Industry and Small and Medium Enterprises has said the expected influx of funds could support development of 1.9 GW of fresh renewables capacity by 2022.
Indeed, per the above, USD 10 trillion of fossil fuel investment must be redirected towards energy transformation by 2030.
Abu Dhabi, United Arab Emirates, 12 January 2020 – The share of renewables in global power should more than double by 2030 to advance the global energy transformation, achieve sustainable development goals and a pathway to climate safety, according to the International Renewable Energy Agency (IRENA). Renewable electricity should supply 57 per cent of global power by the end of the decade, up from 26 per cent today.
A new booklet 10 Years: Progress to Action, published for the 10th annual Assembly of IRENA, charts recent global advances and outlines the measures still needed to scale up renewables. The Agency’s data shows that annual renewable energy investment needs to double from around USD 330 billion today, to close to USD 750 billion to deploy renewable energy at the speed required. Much of the needed investment can be met by redirecting planned fossil fuel investment. Close to USD 10 trillion of non-renewables related energy investments are planned to 2030, risking stranded assets and increasing the likelihood of exceeding the world’s 1.5 degree carbon budget this decade.
“We have entered the decade of renewable energy action, a period in which the energy system will transform at unparalleled speed,” said IRENA Director-General Francesco La Camera. “To ensure this happens, we must urgently address the need for stronger enabling policies and a significant increase in investment over the next 10 years. Renewables hold the key to sustainable development and should be central to energy and economic planning all over the world.”
“Renewable energy solutions are affordable, readily available and deployable at scale,” continued Mr La Camera. “To advance a low-carbon future, IRENA will further promote knowledge exchange, strengthen partnerships and work with all stakeholders, from private sector leaders to policymakers, to catalyse action on the ground. We know it is possible,” he concluded, “but we must all move faster.”
Additional investments bring significant external cost savings, including minimising significant losses caused by climate change as a result of inaction. Savings could amount to between USD 1.6 trillion and USD 3.7 trillion annually by 2030, three to seven times higher than investment costs for the energy transformation.
Falling technology costs continue to strengthen the case for renewable energy. IRENA points out that solar PV costs have fallen by almost 90 per cent over the last 10 years and onshore wind turbine prices have fallen by up half in that period. By the end of this decade, solar PV and wind costs may consistently outcompete traditional energy. The two technologies could cover over a third of global power needs.
Renewables can become a vital tool in closing the energy access gap, a key sustainable development goal. Off-grid renewables have emerged as a key solution to expand energy access and now deliver access to around 150 million people. IRENA data shows that 60 per cent of new electricity access can be met by renewables in the next decade with stand-alone and mini-grid systems providing the means for almost half of new access.
A Frenchman is credited with being the first to discover the photovoltaic effect that produces electricity from sunlight. The first solar panel was built in the US. But when Abu Dhabi decided to build the world’s largest individual solar power project, they looked east for help.
The country partnered with Chinese and Japanese companies to construct a facility, which opened this year, with a peak capacity of 1.18 gigawatts generated by 3.2 million solar panels. That’s because Asia, more than any other region on the planet, and China, more than any other nation, currently represent the future of solar energy, and are at the heart of the ensuing industrywide transformation from fossil fuels to renewable and nuclear energy.
Decarbonization is changing the face of energy and the world economy in more ways than most consumers — and even most executives — appreciate. Besides the transition from molecule to electron, as this move toward electrification suggests, it is also shifting the industry’s economic base from West to East and reconfiguring the hierarchy of companies and geographies that define energy.
Asia is the 800-pound gorilla in the energy story. First, its continued economic growth and rising standard of living will make its constituent nations pre-eminent energy consumers for the foreseeable future. A study by BP indicates that Asia, including China and India, will represent 43% of global energy demand by 2040, and through that year, the region will account for more than 50% of the growth in demand. In contrast, energy demand among the 36 nations in the OECD, which includes most big economies in the Americas and Europe, will be flat.
China’s sunny outlook
Second, places like China are already among the most important suppliers of non-fossil fuel-based energy and technology. By 2017, China owned 72% of the world’s solar photovoltaic module production; in comparison, the US has 1% and Europe 2%. Of the eight top producers, six are Asian. Not including hydropower, China has somewhere around one-third of the world’s installed renewable capacity; the EU has a little over a quarter; and the US accounts for 14%. China also leads in the generation of hydropower.
As the electrification of transportation advances and demand grows for renewable energy storage solutions, China looks likely to monopolize here, too. China produces at least two-thirds of the world’s production capacity for lithium-ion batteries, which are used in electric vehicles (EVs), mobile phones and laptop computers (some estimates put their share at closer to 70%), and it looks likely to hang on to that lead through at least 2028. And besides being the largest market for EVs, China also controls the bulk of production.
China is the third-largest miner of the primary raw material used to produce those batteries, lithium — often referred to as white petroleum because of its mounting economic importance. Chinese producers are also buying up lithium reserves in Chile, the world’s second-largest lithium miner (Australia takes the top spot).
A fundamental overhaul
Of course, climate change is forcing the energy industry to undergo an existential transformation that may eventually see the elimination of fossil fuels entirely. While most executives at oil companies will be dead or at least retired before that transition proceeds to what seems its inevitable end, the slowing of demand is already being felt.
By contrast, the demand for electricity seems insatiable. Electrification rates continue to rise across the globe, with Asia expected to be close to 100% coverage by 2030. Much of that growth in demand may be supplied by renewables and nuclear power rather than fossil fuel-generated power, although natural gas is expected to play a role for years to come. It also may be accomplished through a decentralization of generating capacity, such as recent rural electrification projects in places like Malawi and Bangladesh where farmers and villages use solar panels and small generators to provide their own electricity.
What’s the World Economic Forum doing about the transition to clean energy?
Moving to clean energy is key to combatting climate change, yet in the past five years, the energy transition has stagnated. Energy consumption and production contribute to two-thirds of global emissions, and 81% of the global energy system is still based on fossil fuels, the same percentage as 30 years ago.
Effective policies, private-sector action and public-private cooperation are needed to create a more inclusive, sustainable, affordable and secure global energy system.
Benchmarking progress is essential to a successful transition. The World Economic Forum’s Energy Transition Index, which ranks 115 economies on how well they balance energy security and access with environmental sustainability and affordability, shows that the biggest challenge facing energy transition is the lack of readiness among the world’s largest emitters, including US, China, India and Russia. The 10 countries that score the highest in terms of readiness account for only 2.6% of global annual emissions.
Yet despite the urgency of climate concerns and the rapidly falling cost of renewable energy, the speed at which this existential energy transition will happen is uncertain, as pre- and post-tax subsidies on fossil fuels remain in place, discouraging consumers to make the change to a more environmentally beneficial and frequently cheaper source of energy. The International Monetary Fund estimates post-tax subsidies on fossil fuels like coal and petroleum — a result of unpriced externalities, such as societal costs from air pollution and global warming — totalled $5.2 trillion in 2017.
Regardless of the speed of transformation, there’s no doubt it is already well underway. That’s why places like the United Arab Emirates (of which Abu Dhabi is the largest) are building solar power and nuclear facilities, despite being the world’s eighth-largest oil producer — and making the transition with Asian partners. They see the future.
Gas investments in the Middle East and North African (MENA) region are declining, according to a report from Saudi Arabia-based Arab Petroleum Investments Corp. (APICORP).
The report highlighted worries about the challenge of meeting domestic demand given this slowdown. Private investors are taking a wait-and-see approach, driven by low gas prices, potentially putting more strain on governments.
The Gas Investment Outlook 2019-23 charts a reduction of $70 billion in gas spending from the previous report, 2018-22, but the outlook for petrochemicals has increased by 50%. Of the nine countries covered, investments are set to fall in seven. Petrochemicals are on the rise as countries focus on extracting the most amount of value from oil production.
The most notable fall in gas plans was in Kuwait, down nearly 80%, while Saudi Arabia was down 60%, with Algeria and Iran down around 50% each. Driving the $70bn reduction were Saudi and Iran. This is not necessarily a question of cutting investments, it can also be driven by major projects being completed. Saudi, for instance, commissioned its Wasit gas plant.
While the MENA region has moved towards the consumption of gas, for power generation and industry, continued access to supplies is driven by the government’s willingness and ability to pay for these supplies. This willingness will have a direct impact on meeting future supplies, APICORP said. Saudi is planning an additional 12 GW of greenfield power, while Egypt has 9 GW of projects, which “will require additional gas supplies”.
LNG supplies in the area are playing a part in meeting increased demand. Regasification terminals are on track in Kuwait and the United Arab Emirates, while Qatar is working on expanding its export capacity to 126 million tonnes per year by 2027. Around the world, for the first time, investment commitments in new LNG capacity this year passed the $50bn mark. Global demand for gas is increasing, it noted, but supply may outpace this until 2023, although a number of factors – trade wars and geopolitical tensions – are complicating such calculations.
While Qatar is working to cement its dominance of the liquefaction sector, Saudi Aramco is taking steps to become a player, having signed a deal this year for a potential interest in the Port Arthur LNG plan, in the US. Construction of Qatari trains are expected to carry a price tag of around $15bn.
Iran is leading the charge in gas and petrochemical investments, followed by Egypt, despite the countries’ share of spending to 2023 declining by $11bn and $5bn respectively from the previous APICORP report.
Saudi has made progress on its energy intensity of GDP and is increasing gas production, with the target of increasing sales gas volumes to 164 bcm per year by 2026. There are challenges to gas in the kingdom, including alternative fuel stocks, while shale production has gained some attention but carries a high cost, at $6-10 per mmBtu.
Abu Dhabi is also pursuing unconventional gas resources such as shale, in addition to offshore sour gas. The state imports gas via the Dolphin link, with LNG coming via two regas terminals. Abu Dhabi also began
Algeria must tackle the problem of low upstream spending and access to technology around maturing fields, in particular its Hassi R’mel field. Just over $8bn is expected to be invested in the country during the next five years, APICORP said. Companies working in the country’s energy sector have struggled with bureaucracy, with the report citing the recent cancellation of the $100 million debottlenecking project at the Rhourde Oulad Djemma field.
Production and exports have declined in 2019, with new fields coming onstream in the southwest providing only a “short-term fix”. Gas flaring accounts for the equivalent of 20% of Algeria’s domestic consumption, suggesting this might be one area for improvement.
The APICORP report described Egypt as “touting itself as a gas hub”, based on regional supplies, from states such as Israel, and existing infrastructure “but key elements are still amiss”. The country expects to consume 72 bcm of gas in 2020 and 92 bcm in 2021, APICORP said, citing Egypt’s plans. The North African state could run into a net deficit in 2025, on high domestic consumption and increased LNG exports.
Oil traders, OPEC+ members and Big Oils alike are all predicting for the global oil industry to remain dominant in the energy supply market up until 2040. Their newly born Renewables counterparts can’t hear it from that ear. Is it all about that? A fight between 2 vested interests camps or is it about as elaborated by Robin McKenna, University of Liverpool in his Climate change: three ways to market the science to reach the sceptics, a matter of mind over matter. As an obvious illustration of the current situation, the latest COP 25 disappointment is clearly not a surprise.
You might think that the answer is more or better science education. The more you know about climate science, the more likely you will be to think that climate change is real.
But the science says that this isn’t true. If you want to predict what someone’s attitude to climate change is, you are better off asking them about their politics than about science. In fact, in the US, the more numerate and scientifically literate a Republican you are, the more sceptical you are about climate change.
What climate science really needs is better marketing. Researchers might think that the science sells itself. But, while people might trust scientists in general, the picture is more mixed when it comes to politically charged issues such as climate change. With many politicians actively persuading people that the science isn’t that serious, we need to persuade people that these politicians are wrong and the climate scientists are right.
And luckily, there are three key marketing tools we can use to do so.
This framing doesn’t work for all audiences. Just as a good marketer fits their message to their audience, a good science communicator will understand that when communicating an issue so broad and that affects so many, it makes sense to frame climate change in different ways to different groups of people.
Debunks of climate myths abound on the internet. But debunking misinformation is tricky, because once a piece of information has entered someone’s mind, it’s hard to dislodge it – especially if the information confirms previously held beliefs.
An alternative strategy is “prebunking”. Inspired by inoculation theory – the idea that it is better to a prevent a disease than to treat it – prebunking aims to prevent misinformation from spreading in the first place, rather than debunk it once it has spread.
This can be done by identifying common argumentative strategies used by climate change sceptics, such as spurious appeals to expertise or exaggerations about the uncertainties in climate models, and explaining why they are dodgy.
Of course, this information needs to reach the right people. Much like protection against disease, the most effective inoculation starts in childhood, with education. Misconception-based learning, an approach which sets out to avoid misconceptions, provides a framework for doing this. Climate breakdown is not a flash in the pan problem, and our strategies to combat it need to be designed for the long haul.
Master the messenger
Finally, it’s important to focus not just on the message, but the messenger too. We would rather listen to people who share our political views than “experts” who disagree with us. This means that if you want to effectively communicate a pro-science message, you need to have people from different corners of the political spectrum making the case.
It’s great that activists like Greta Thunberg are spreading the word, but not everyone wants to listen to them, and there are politically diverse groups out there who share the same message. For instance, when he was president Barack Obama reached out to religious leaders, who played an active role in promoting environmental issues in their communities.
Marketing isn’t always a bad thing
Marketing is manipulative. It can try to trick us into buying things we don’t want. So using it to sell climate science and interfere with our basic right to make up our own minds might seem suspect.
But it’s important to remember that while climate change is a contentious political issue, its effects are real and severe no matter what you, I or anyone else think. We have the right to decide how or even whether to change our behaviour in light of a destabilising climate. But we don’t have the right to decide that our actions have no impact on the climate. As the saying goes, we are not entitled to our own facts.
What’s more, there is a difference between the aims of marketers and those of scientists trying to communicate with the public. The marketer wants to sell us stuff. The scientist wants us to break through our ideological biasesand apathy to engage with the truth.
The strategies I have outlined are designed to create the conditions for these breakthroughs. They don’t detract from our ability to make up our own minds. In fact, they may enhance it, precisely because they neuter our ideological biases. Sometimes, we need a little help to think for ourselves.
Of course, good marketing is no guarantee of a sale. Even if scientists use these methods, climate change sceptics may refuse to buy it. But good marketers also don’t give up. If these methods don’t work, we can always look for some other ones.
The MENA region has $100 billion worth of clean energy projects currently in the pipeline, according to a report by Energy & Utilities.
The report estimates total investment in clean energy to exceed $300 bn by 2050 if the region’s utilities are to meet their ambitious targets.
Middle East Energy said that the sharp drop in the cost of solar and wind power technologies is driving clean energy, with the cost of installing photovoltaic (PV) solar and wind having fallen by 73 percent and 80 per cent respectively since 2010.
The commissioning of the world’s largest single-site photovoltaic (PV) solar plant in 2019, the 1.17GW Sweihan independent power project (IPP) in Abu Dhabi, is one of the milestones reached this year in the push for clean energy, the report noted.
Dubai also reached financial close for a $4.3 billion concentrated solar power (CSP) project, Noor Energy 1, which is the largest single-site power investment project in the world.
The report estimates that installed power generation capacity will be required to increase 35 percent by 2025 just to meet rising demand in the Middle East. Rapid population growth combined with ambitious industrial and economic expansion programmes is resulting in the growing need for power, as demand for electricity is expected to triple by 2050.
“Driven by well-designed auctions, favourable financing conditions and declining technology costs, renewables are being brought into the mainstream. Based on the renewables targets already in place, the region, led by the UAE, could save 354 million barrels of oil which is equivalent to a 23 per cent reduction, cut the power sector’s carbon dioxide emissions by 22 percent, and slash water withdrawal in the power sector by 17 percent by 2030,” Gareth Rapley, Group Director, Industrial, at Informa Markets said.
The report was published as a preview to an event in Dubai, The Middle East Energy 2020, which will be organised by Informa Markets in March 2020.
The insatiable demand of the global building boom has unleashed an illegal market in sand. Gangs are now stealing pristine beaches to order and paradise islands are being dredged and sold to the construction industry was the introduction to an article of The Guardian. A less partial response to that would definitely that of Seyed Ghaffar, Brunel University London proposes here below to how we can recycle more buildings.
More than 35 billion tonnes of non-metallic minerals are extracted from the Earth every year. These materials mainly end up being used to build homes, schools, offices and hospitals. It’s a staggering amount of resources, and it’s only too likely to increase in the coming years as the global population continues to grow.
Thankfully, the challenges of sustainable construction, industrial growth and the importance of resource efficiency are now clearly recognised by governments around the world and are now at the forefront of strategy and policy.
A critical component of the UK government’s sustainability strategy concerns the way in which construction and demolition waste – CDW, as we call it in the trade – is managed. CDW comes from the construction of buildings, civil infrastructure and their demolition and is one of the heaviest waste streams generated in the world – 35% of the world’s landfill is made up of CDW.
The EU’s Waste Framework Directive, which aims to recycle 70% of non-hazardous CDW by 2020, has encouraged the construction industry to process and reuse materials more sustainably. This directive, which favours preventive measures – for example, reducing their use in the first place – as the best approach to tackling waste, has been implemented in the UK since 2011. More specific to the construction industry, the Sustainable Construction Strategy also sets overall targets for diverting CDW from landfill.
Policies worldwide recognise that the construction sector needs to take immediate action to reduce greenhouse gas (GHG) emissions, tackle the climate crisis and limit resource depletion, with a focus on adopting a circular economy approach in construction to ensure the sustainable use of construction materials.
Instead of simply knocking buildings down and sending the CDW to landfill, circular construction would turn building components that are at the end of their service life into resources for others, minimising waste.
It would change economic logic because it replaces production with sufficiency: reuse what you can, recycle what cannot be reused, repair what is broken, and re-manufacture what cannot be repaired. It will also help protect businesses against a shortage of resources and unstable prices, creating innovative business opportunities and efficient methods of producing and consuming.
Changing the mind-set
The mind-set of the industry needs to change towards the cleaner production of raw materials and better circular construction models. Technical issues – such as price, legal barriers and regulations – that stand in the way of the solutions being rolled out more widely must also be overcome through innovation.
Materials scientists, for example, are currently investigating and developing products that use processed CDW for manufacturing building components – for example, by crushing up CDW and using it to make new building materials.
Technical problems around the reuse of recycled materials should be solved through clever material formulations and detailed property investigations. For instance, the high water absorption rate in recycled aggregates causes durability problems in wall components. This is something that research must address.
Moreover, it is illegal in the EU to use products that haven’t been certified for construction. This is one of the main obstacles standing in the way of the more widespread reuse of materials, particularly in a structural capacity. Testing the performance of materials for certification can be expensive, which adds to the cost of the material and may cancel out any savings made from reusing them.
For the construction, demolition and waste management industries to remain competitive in a global marketplace, they must continue to develop and implement supply chain innovations that improve efficiency and reduce energy, waste and resource use. To achieve this, substantial research into smart, mobile and integrated systems is necessary.
Radically advanced robotic artificial intelligence (AI) systems for sorting and processing CDW must also be developed. Many industries are facing an uncertain future and today’s technological limitations cannot be assumed to apply. The construction industry is likely to be significantly affected by the potential of transformative technologies such as AI, 3D printing, virtual/augmented reality and robotics. The application of such technologies presents both significant opportunities and challenges.
A model for the future
As the image below shows, we have developed a concept for an integrated, eco-friendly circular construction solution.
Advanced sensors and AI that can detect quickly and determine accurately what can be used among CDW and efficient robotic sorting could aid circular construction by vastly improving the recycling of a wide range of materials. The focus should be on the smart dismantling of buildings and ways of optimising cost-effective processes.
The industry must also be inspired to highlight and prove the extraordinary potential of this new construction economy. We can drive this through a combination of creative design, focused academic research and applied technology, external industry engagement and flexible, responsive regulation.
Only through a combination of efforts can we start to recycle more buildings, but I’m confident that with the right will – and the right investment – we can start to massively reduce the amount of materials we pull from the ground each year and move towards a truly sustainable future.
The World Bank in its “Adaptation to Climate Change in the MENA Region” predicted that this region being particularly vulnerable to climate change, it should do more to adapt to water scarcity and heat and adjust all institutional mechanisms to deal with these environmental constraints. Environmental awareness in the Arab world posted on The Arab Weekly of 17 Novembre 2019 is a good illustration of this latest trend.
Lebanon was the country with the strongest concerns about climate change in general, followed by Tunisia and Egypt.
Climate change is a global emergency that respects no borders but results from a recent survey revealed that, when it comes to convincing MENA populations to come to grips with the crisis, substantial barriers remain.
Recent data gathered by Arab Barometer, a nonpartisan research network that has conducted opinion surveys across the region since 2006, indicated that a strong majority of respondents said they were “very concerned” about water and trash pollution (70% and 66%, respectively). Both issues are immediate problems that MENA residents must often deal with directly and can see with their own eyes daily.
However, when it came to more abstract or long-term environmental issues, such as climate change and air quality, fewer survey respondents said they were very worried (35% and 44%, respectively).
Opinions showed no significant variations across age and gender groups. However, more educated and affluent respondents expressed slightly stronger concerns about climate change in general.
The survey uncovered dividing lines geographically: Residents in rural areas were more likely to view climate change as a “very serious” problem than those living in urban environments.
Lebanon was the country with the strongest concerns about climate change in general, followed by Tunisia and Egypt, but national differences on specific issues were the starkest. Air quality was considered a “very serious” problem for 57% of respondents in Libya but only for 25% of those surveyed in Kuwait.
The survey adds credence to the argument that a region-wide effort must be made to build awareness about climate change.
The new Law of Hydrocarbons in Algeria: distinguishing economic time from political time was enacted despite concurrent street demonstrations against it. It was debated at length by Professor Abderrahmane MEBTOUL, International Expert, in interviews to Radio Algeria International – Paris France on 04/11/2019, to Algerian Radio Channel-3 and to Radio France International on 05/11/2019. Here are some excerpts of each.
Question – 1. Will Algeria with high domestic consumption be able to meet its international commitments?
Indeed, if we take natural gas, domestic consumption is likely to exceed 60 billion cubic meters of gas by 2030 and 100 billion cubic meters of gas between 2035/2040, the Ministry of Energy has announced the depletion of reserves would be at about 60%. An urgent need to review the current energy policy and move towards a clean energy transition policy that revolves around four axes, to meet its international commitments.
-First: an energy efficiency policy (energy sobriety) that affects all sectors and households by reviewing construction methods, cars/trucks fleet consumption, energy-intensive industrial units; the simple referring to a policy of targeted subsidies, but which do not penalize the disadvantaged, existing new technologies that save about 30% of energy consumption.
-Secondly: the development of renewable energies whose cost has fallen by more than 50% for both thermal and photovoltaics, where Algeria has significant potential.
-Thirdly: to continue to invest in upstream, which can make discoveries as part of a win-win partnership, SONATRACH with lower prices and physical production, which has dropped significantly since 2008, technological or financial capabilities, but no longer have to be deluded by large deposits like Hassi-Messaoud or Hassi-Ramel.
-Fourthly: avoid precipitation whilst developing SHALE oil and gas, Algeria having the third world reservoir, only by 2025, as I recommended to the authorities of the country, through this study with experts pending new technologies that replace hydraulic fracturing, saving freshwater and injecting more than 90% of the chemicals into wells, thus protecting the environment, but requiring in-depth social dialogue.
To answer your question directly, I highlighted the points at the 5 + 5 Meeting of Algeria, Morocco, Tunisia, Mauritania, Libya with France, Italy, Spain, Portugal, Malta in Marseille in June 2019. I had the honour of chairing the Energy Transition’s workshop in which the subject of a clean energy transition policy, and the modification by Algeria, a major energy player in the Mediterranean basin, as it has always done, to meet its international commitments by 2030.
Question – 2. Will the amendment of this law attract foreign investors?
Depending on several factors, such as:
-First: the revision of this law as I have pointed out since its enactment at the beginning of 2013 is unsuited to the current situation, in particular the tax component and the nature of the contracts in which Sonatrach supports the majority of the financing, the world having evolved from where the importance of its revision to take account of new global energy changes.
-Secondly: however, a law is only a legal instrument, being a necessary but sufficient condition of the attractiveness of foreign investment, where any company attracted by direct profit rate, and also as long as the level of foreign exchange reserves is high. Depending on the business environment where Algeria was in the latest report of the World Bank of 2019 was very poorly classified because of its paralyzing bureaucracy, corruption, financial and unsuitable socio-educational systems.
-Thirdly: the political climate is decisive, and according to international observers no serious investor would engage in Algeria without the resolution of the political crisis, political stability especially in a country like Algeria, where politics and economics are intertwined, being a determining factor in the attractiveness of a foreign investment.
-Fourthly: as I have just pointed out recently, to your colleagues on France 24 television, and several Algerian websites and daily newspapers, it would be desirable to postpone the adoption of this law after the presidential election. Only a president and a legitimate government can secure the future of the country where this resource, directly and indirectly, provides about 98% of the country’s foreign exchange resources. Some company executives fear that a new president would challenge this law, which would be passed by a transitional government, responsible for current affairs, while legal stability is a golden rule for all investor.
-Fifth: to answer this second question directly, the positive impact of this law would depend on the future global energy map, the entry of new producers and the sale price on the world market both of oil and gas returning at the cost of production in Algeria therefore to a new strategic management of SONATRACH and the impacts would not be felt only in three to four years, subject to the lifting of environmental constraints. Why this haste, which risks further sharpening social tensions in the run-up to the presidential election, thus possibly harming the voting turnout?
