Green hydrogen must be made from green electricity. But the electricity used for making it must fulfil stricter requirements than conventional green electricity. Matthis Brinkhaus at Energy Brainpool describes the criteria by which hydrogen can be designated as 100% renewable: Additionality; Additionality Plus; Temporal correlation, simultaneity; Geographical correlation, regionality. Brinkhaus points at where exceptions can be made, and where … [Read more...]
Batteries made of super-hot sand: for long-duration grid storage at $4 to $10 per kWh
Our electric future needs low-cost long-duration storage for grids. Per kWh, pumped hydropower is about $60, compressed air energy storage (CAES) costs from $150 to $300, and lithium-ion batteries cost around $300 (and only store energy from one to four hours). Wayne Hicks at NREL describes research into thermal energy storage (TES) using solid particles such as sand which is abundant worldwide. With a duration lasting hundreds of hours, … [Read more...]
EU ETS2 for Buildings, Road Transport in 2027: why we need auctions to start early
The EU has established a second emissions trading system (ETS) to put a carbon price on buildings and road transport, the “EU ETS2”. The ETS2 starts in 2027, but monitoring and reporting of ETS2 emissions will begin in 2025. One issue is that an ETS means prices for long-term fuel supply contracts will be affected, so a crucial question for firms is how to hedge their potential exposure, says Ingo Ramming at BBVA writing for the Florence School … [Read more...]
Why isn’t Methane included in the EU’s Carbon Border Adjustment Mechanism?
Robert Kleinberg at CGEP explains why methane isn’t included in the EU’s Carbon Border Adjustment Mechanism (CBAM) which imposes a carbon tax on imported goods. Basically, CO2 emissions are easy to estimate accurately, whereas methane emissions are not. Many methane emissions, even the largest ones, are intermittent and of highly variable duration. Gas leaks vary over many orders of magnitude, and once diffused in the atmosphere leave no local … [Read more...]
EVs, Batteries: how can Europe use tariffs on China without starting a trade war?
Europe must decarbonise as fast as possible while safeguarding essential economic, social and security interests. Decarbonisation without deindustrialisation needs carefully thought-out trade policy, and tariffs can be an effective instrument, explains T&E, summarising its recently released paper. Almost a fifth of all EVs sold in the EU last year were made in China. Over half of those were made by Western carmakers operating in China, but … [Read more...]
Can the six Gulf nations meet their ambitious Renewables deployment plans by 2030?
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...]
France’s €100/month EV “social leasing” plan was oversubscribed, then closed. How to keep the momentum going
On January 1st France launched its flagship EV “social leasing” programme, at a typical price of €100/month, targeting 25,000 users. Within six weeks it was oversubscribed, forcing the government to close the scheme and alter the subsidy regime to accommodate the new total of 50,000. The programme’s popularity demonstrates its relevance and justifies its future expansion. However, the system needs to change if it is to meet the challenges … [Read more...]
Carmakers must stop complaining and meet the 2025 EU CO2 target (like they did in 2020, and profitably)
In 2025, the EU’s car CO2 regulation will require a 15% reduction of fleet emissions from new passenger cars sold in Europe, compared to 2021 figures. But some carmakers are saying this target is unfair, claiming that they cannot control the consumers’ appetite for EVs. They want targets relaxed or fines waived. Julia Poliscanova at T&E explains why their complaints are unwarranted for a number of reasons. Previous deadline dates show that EV … [Read more...]
Study: will sight of a Wind Turbine reduce your property prices?
Onshore wind turbines have a permitting problem in the U.S. and Europe. One main complaint from homeowners is that they believe the sight of a turbine will reduce their property value. Maximilian Auffhammer at the Energy Institute at Haas describes his co-authored published study that tests this assumption. The study looks at sale prices of over 300m homes in the U.S. within 10km of a turbine, sold between 1990 and before COVID hit. The clever … [Read more...]
Infrared Fabric heat-emitting “wallpaper” avoids the disruption and expense of Heat Pumps
Hundreds of millions of buildings across the world need clean heating. But retrofitting them all for heat pump installation is going to be expensive, disruptive, and take a long time. Michael Siebert at Nottingham Trent University describes a completely different approach, using new high-tech infrared fabrics that emit heat. Made of graphene, they can be installed as easily as wallpaper. The radiated heat can be felt instantly, unlike the slow … [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...]
New Offshore Wind projects: is permitting being slowed by evidence from “grey literature”?
Offshore wind is the new frontier of clean energy generation. The permitting process depends on policymakers’ evaluation of the impact assessment evidence. As Claire Szostek at the Plymouth Marine Laboratory explains, that evidence has two sources: primary and “grey” literature. “Primary literature” comes from structured peer-reviewed scientific journals. “Grey literature” includes all other types of reports and evidence published freely. The … [Read more...]
