The six Gulf Cooperation Council (GCC) countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabi, UAE) have all set themselves ambitious renewable energy targets to meet in the next ten years. They are some of the sunniest countries in the world, and existing projects have set records for low solar power costs. But they have a long way to go. In 2022, GCC renewable capacity was 5.7GW, primarily solar PV, out of 165GW of total generating capacity, … [Read more...]
Iron-air batteries: long-duration grid storage targets 1/10th the cost of lithium-ion
Wind and solar need cheap, long-duration storage to even out its inherent weather-determined intermittency. Deborah Halber, writing for MIT News, describes the development of iron-air batteries. Iron is cheap and available worldwide. Storage duration is multi-day. They are much heavier and take up more space than lithium-ion batteries, but that doesn’t matter for immobile grid storage. The target price tag of $20/kWh (one-tenth the cost of … [Read more...]
Explainer: The EU’s Green Deal Industrial Plan
Here, the Florence School of Regulation (FSR) provides a summary of the Green Deal Industrial Plan. It’s broken up into: What is the Green Deal Industrial Plan? What are critical raw materials and why do they matter? Where is the EU currently standing on critical raw materials? What is the EU doing about critical raw materials? Where is the EU currently standing on clean tech? How is the EU attempting to boost its domestic clean tech sector? Can … [Read more...]
Who is winning the Clean Energy race between China, Europe, and the US?
“X-Change: The Race to the Top” is the fourth report of an RMI series that reviews the cleantech competition between China, Europe, and the US. Kingsmill Bond, Sam Butler-Sloss and Daan Walter at RMI summarise the findings of the latest report, along with six charts, which focuses on four areas: clean technology supply chains, solar and wind deployment, EV sales, and electrification. Solar and wind deployment is still a close contest. But China … [Read more...]
Europe’s cross-border Interconnectors: how JAO auctions optimise energy flows, prices
Interconnectors allow for cross-border flows of energy between two markets that would otherwise not be connected. Through an economic convergence between supply and demand, the cheapest marginal producer located anywhere in these two markets should be able to set market prices. As Jean-Baptiste Vaujour at the Emlyon Business School explains, the central question is to find an optimal allocation of the scarce interconnection capacity between the … [Read more...]
Solar PV technology improvements are rapid. But how do you test the long-term reliability of the new designs?
Solar PV module technology moves fast, and is delivering improvements continuously. So fast that it’s no trivial matter to judge the long-term reliability of the changes. It’s a crucial issue as modules, once deployed, are expected to deliver results over lifetimes that span decades. Sara Fall and Jarett Zuboy at NREL describes a process designed to identify and address potential reliability problems quickly, before they are observed in the … [Read more...]
Financing Europe’s cross-border Interconnectors to deliver energy security, lower prices: a look at incentives and policies
The EU and its Member States are building out interconnectors to improve security of supply and affordability of electricity through the physical and economic linking of national energy markets into a single, synchronised European market. But each interconnector is expensive, complex and therefore risky. They can span long distances or natural obstacles such as mountains or seas. Significant network planning and adaptation is needed to account … [Read more...]
ReDREAM pilot: mobile app for real-time green energy availability, prices, to control your usage
We already have the technology to allow households to monitor and control their energy usage so they can run individual appliances when the energy is cheapest and greenest. It just needs to be tested and then deployed at scale. Luca Arfini, writing for ESCI, describes the EU-funded ReDREAM project where over 700 people in four countries have had the monitoring installed in their homes, and been given the mobile app to control their usage. … [Read more...]
Study: universities worldwide are still producing far more graduates for fossil fuels than for clean energy
Universities worldwide still produce more workers for fossil fuels than for renewable energy industries. Roman Vakulchuk and Indra Overland at the Norwegian Institute of International Affairs summarise their new study on the energy transition in global higher education, published by the Energy Research & Social Science journal. The study is based on a review of 18,400 universities in 196 countries. 68% of the world’s energy educational … [Read more...]
Two years on, how is Russia’s invasion of Ukraine driving energy security and decarbonisation?
Russia’s invasion of Ukraine has boosted anxiety and therefore action on energy security and dependence on oil and gas. Sanctioning Russian oil and gas imports is an opportunity to replace fossil fuels with low or no carbon alternatives, an opportunity that is being taken. And renewables like wind and solar are by their nature local and therefore good for energy security (though with notable exceptions). Charles Hendry, Ellen Wald, Olga Khakova, … [Read more...]
Italy: Capacity Auctions for 71 GWh of additional Grid Storage
Italy needs 71 GWh of new utility-scale electricity storage capacity by 2030 to meet EU targets to cut emissions by at least 55% by 2030, according to Terna which manages Italy’s transmission grid. ***STOP PRESS*** This Tuesday at 11:00 CET, Energy Post is exclusive media partner to a dedicated webinar (organised by ATA Insights/RENMAD) on Capacity Market Auctions REGISTER FREE HERE. In this article, Sara Stefanini summarises the Terna study, … [Read more...]
District Heating: Molten Salt boilers beat Water for storing intermittent Wind & Solar power
District heating networks, an important part of the energy transition for buildings, need a way of storing intermittent wind and solar power. But water tanks have limits: they take up a lot of space, and have a low thermal energy storage density (limited by the 100°C boiling point). Molten salts have a much higher storage density (regular table salt has a melting point of 801°C), but a melting point that is too high is not safe where ordinary … [Read more...]
Tandem solar cells (perovskite + silicon) can reach 40% energy conversion rates
Tandem solar lays new perovskite cells over standard silicon cells. Perovskite absorbs the shorter wavelengths of light that silicon misses. So the thin layer of perovskite collects the visible wavelengths, and lets the near-infrared light through to the silicon underneath. Martina GrĂĽnwald and Sarah Michaud writing for the WEF point at the results of R&D and demonstrations in Germany, Switzerland, Saudi Arabia and China. Energy conversion … [Read more...]
EU’s fossil fuel CO2 emissions drop to levels last seen in the 1960s
The EU’s CO2 emissions from fossil fuels (including power generation, industry and transport) dropped 8% in 2023 year-on-year, reaching levels last seen in the early 1960s, reveals an analysis by CREA. More than half of that decline came from an impressive 25% year-on-year reduction in CO2 emissions from power generation. The cleaner electricity mix is thanks to the continuous rise of wind and solar as well as a rebound in hydropower and nuclear. … [Read more...]
Massive global expansion of Renewables coming. But we’re still short 20% of our 2030 target
The IEA has released the 143-page “Renewables 2023”, the latest edition of its annual report on the sector. The world added 50% more renewable capacity in 2023 than in 2022 and the next 5 years will see fastest growth yet. Under current policies and market conditions, global renewable capacity is already on course to increase by two-and-a-half times by 2030: great news but still short of the tripling we need. A key reason for the gap is the lack … [Read more...]
