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...]
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...]
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...]
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...]
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...]
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...]
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...]
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...]
“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...]
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...]
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...]
H2-DRI-EAF uses hydrogen (H2) to produce direct reduced iron (DRI), which is then processed in an electric arc furnace (EAF) to produce steel. The two main challenges are ensuring an adequate supply of DR-grade iron ore, and cutting the end-to-end cost of making hydrogen. But right now, clean green hydrogen production is in its infancy, and therefore so are green steel plans. Soroush Basirat at IEEFA surveys the landscape, looking at the U.S., … [Read more...]
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...]
11% of global energy-related carbon emissions are embedded in the construction of buildings. Though focus has been on reducing operational emissions (28%, from heating and cooling, power etc.) there is not enough attention paid to construction, explains Carolina Kyllmann at CLEW. She looks at all the issues, including production of materials, transport to the site, construction, renovations, demolition and reuse of materials, and more. Kyllmann … [Read more...]
Credit rating agencies now clearly recognise that climate change has become its own risk category, explains Tom Sanzillo at IEEFA who summarises his 43-page report. Financially, the coal, oil and gas sectors have served the world for decades. But due to regulatory, legal, economic, financial, political and social concerns, coal is credit negative and oil and gas is no longer positive. Sanzillo’s report charts the gradual erosion of the sector’s … [Read more...]
