Underground geological formations have more space to store CO2 than we’ll ever need, by orders of magnitude. But the process of assessing the best locations can take up to ten years, so that work needs to start now, say Raimund Malischek and Samantha McCulloch at the IEA. The main constraints are technical (which porous rock formations absorb CO2 most easily, etc.), while the displacement of land use and public acceptance must also be considered. … [Read more...]
Carbon Capture in Germany: are industry, government and innovators starting to move?
For two years there was little movement after German Chancellor Angela Merkel put carbon capture, removal, and storage back on Germany’s agenda. But the past few months have seen pressure build for a launch of CCS that may model itself on Germany’s success with solar, explains Lee Beck writing for Atlantic Council. Political voices both within and outside government, as well as investments by giants like Heidelberg Cement and Linde, are giving … [Read more...]
Outlook USA: even with battery costs, Wind and Solar can undercut Coal and Gas by 2023-24
IEEFA has published its U.S. Power Sector Outlook 2021. Its authors, Dennis Wamsted, Seth Feaster and David Schlissel summarise and explain the projections. They say that coal and gas are set to become the biggest losers as renewable generation climbs quickly. The future for wind and solar – coupled with storage to address intermittency - is looking very good. They present estimates from NextEra (the largest renewable energy developer in the … [Read more...]
Case studies: Strategic EV funding starts with an Essential Charging Network
Building a nationwide EV charging network is a daunting prospect. Camille Kadoch and Julia Hildermeier at RAP look at those places that are being strategic about it, starting with an essential network that will allay the concerns of consumers on the verge of buying an EV but put off by worries that they will get stuck somewhere with a flat battery. That’s frustrating, given the average American drives only 37 miles a day and Europeans 32 … [Read more...]
Netherlands: gas phase-out transition must tackle the geopolitical implications of importing from Russia
Until recently, the Netherlands has had no major concerns regarding natural gas security of supply. That’s just as well, given gas plays a big role primarily in the generation of heat: 90% of buildings and 40-50% of industrial heat are based on gas. Now, decarbonisation plans to cut its own gas production as well as consumption brings with it major dilemmas. Irina Patrahau and Lucia van Geuns at The Hague Centre for Strategic Studies present a … [Read more...]
Are Regulations and Climate Activism the main driver for coal exits, not Gas and Renewables prices?
It’s widely thought in the media and politics that market forces are now the primary driver for the demise of coal: mainly natural gas prices, and the rising adoption and competitiveness of wind and solar. However, David Drake and Jeffrey York at the University of Colorado Boulder present their research from the U.S. that suggests the two main drivers are federal policy and climate activism. They studied the retirement of 348 coal-fired units … [Read more...]
Can the U.S. switch on a Nuclear Fusion plant by 2035?
Momentum is building in the U.S. for the switching on of a nuclear fusion pilot plant by 2035. A report from the National Academies of Sciences, Engineering and Medicine lays out for the first time the required technical, economic, and regulatory standards. It comes soon after the prospects for fusion were boosted in January by a government bill that funds fusion activities. Peter Dunn at MIT reviews the report and speaks to the experts. The main … [Read more...]
Berkeley Lab releases progress report on state renewable energy standards
Berkeley Lab has released an annual status report on U.S. renewables portfolio standards (RPS), providing an overview of key trends associated with state RPS policies. The report, U.S. Renewables Portfolio Standards 2021 Status Update: Early Release, published in slide-deck form along with accompanying data files, describes recent legislative revisions, key policy design features, compliance with interim targets, past and projected impacts on … [Read more...]
Updated NDCs: World committing to 0.5% emissions cuts by 2030. It should be 45%
The latest national climate pledges, submitted over the new year, show that the world is nowhere near meeting our emissions reductions goals. Analysis of the 48 updated “nationally determined contributions” (NDCs) submitted so far (everyone must submit by the end of this year), covering nations responsible for 29% of global emissions, shows we will have 0.5% lower emissions in 2030 compared to 2010. That’s way off the target 45% reduction needed. … [Read more...]
EU, U.S. exploring new sources of Rare Earth Minerals, should China limit exports
Reports are emerging that China is considering the restriction of the export of rare earth minerals, as a result of tensions with the U.S. Given China controls around 80% of global supply it would have severe consequences for not just advanced military applications (the presumed primary target) but also clean energy technologies like EVs and wind turbines. However, if the threat is carried out, Lukas TrakimaviÄŤius explains how this could backfire … [Read more...]
Wave Energy: how variable geometry designs can raise conversion efficiency
Wave energy is another renewable technology waiting to break through. One main challenge is that about 35%–50% of WEC (wave energy converter) costs come from the device structure alone. Researchers at NREL are experimenting with variable geometry, changing the shape of the WEC so that in more energetic seas the structural loads are controlled. In turbulent seas the excess load can easily be shed, while when the seas are quiet the maximum energy … [Read more...]
Aviation and Shipping emissions: will Biden take on the challenge?
William Todts at Transport & Environment is very worried about the Biden administration’s approach to aviation and shipping emissions. The signals are that the U.S. wants to work through the International Civil Aviation Organization (ICAO) and the International Maritime Organization (IMO). But they have neither the ability nor the means to spur technological breakthroughs. That matters, because it’s only the use of alternative fuels that can … [Read more...]
U.S. supports carbon capture R&D and commercialisation
Many are hoping that the new U.S. administration becomes a climate leader. Nowhere is leadership needed more than in the field of carbon capture. Most net zero pathways give it an essential and major role, yet the possible solutions are still in their infancy. Anne Canavati at the Atlantic Council looks at the new bills being passed in Washington that appear to be the beginnings of a serious push to develop and commercialise Carbon Dioxide … [Read more...]
How Biden can start to find a compromise on Nord Stream 2
The Trump administration and the U.S. Congress threatened sanctions on European companies helping to build the Nord Stream 2 gas pipeline, and that is still the current position of the new U.S. government. To end the deadlock, president Biden needs to change the tone of the debate and focus on the true interests of the affected parties, explains Nikos Tsafos at the Center for Strategic and International Studies (CSIS). He summarises those … [Read more...]
Washington State (U.S.) bill could make it the home for next generation Nuclear
Nuclear may soon be getting a boost from Washington State in the north-west of the U.S. There, a bill is being presented to promote the manufacture and deployment of new nuclear reactors. It will provide generous tax incentives to nuclear investments in the state. It’s the sort of support that renewable energy technology is used to, yet nuclear struggles to get because of critics of nuclear energy. That opposition is very frustrating, explains … [Read more...]
