In March, the Biden administration announced a bold target to deploy 30GW of offshore wind capacity by 2030. Until now, offshore wind’s rise has been driven almost exclusively by Europe and China. The U.S. accounts for just 0.1% of the world’s installed capacity (versus 17% for onshore wind). Why the hold up, given the U.S. could require up to 400GW of offshore wind by 2050? As Stephen Naimoli and Nikos Tsafos at CSIS explain, offshore costs … [Read more...]
What is making Denmark a decarbonisation success? Policy, society, geography
Denmark is proving itself to be a decarbonisation leader, happy to turn its back on its history of oil and gas production and heavy reliance on coal. Its ambitious goal of cutting GHG emissions by 70% by 2030 makes it a global policy frontrunner, second only to Finland which aims to be climate neutral by 2035. Thibault Menu references his report for IFRI that asks what makes Denmark special. It has a long tradition of  providing stability and … [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...]
Public opposition and grid integration costs: the two limiting factors for Wind?
Are we heading for an over-reliance on wind? With wind generation costs continuing to drop dramatically, Schalk Cloete takes a data-driven look at the obstacles wind will face as its contribution to the global energy mix (a little over 2% today) keeps rising. In the main, it is grid integration and public opposition to very visible turbines – and they are related. Putting turbines out of sight and offshore will increase transmission costs. And … [Read more...]
Understanding battery costs better: Li-ion costs have dropped 97% in 30 years
There are two revelations here. First, quite how dramatically lithium-ion battery costs have dropped since 1991 – by 97%. Second, that nobody has been able to agree on how big that drop has been. But agreement on that number – and an established procedure to therefore make good forecasts - is vital for policy makers and related clean energy players. They need to know how much of a role batteries can play in the electrification of transport as … [Read more...]
“The Role of the EU ETS in Decarbonisation to 2030” [written summary of the panel discussion]
Here you can read a summary of the online discussion from March 19th 2021 on the current debate over the review of the EU ETS. The full video is available here. Of primary concern for fossil-dependent lower income nations is the carbon price rising so high that it reduces available budget for investment in clean energy. If that happens there’s clearly a problem. The counter argument is that there are other funding mechanisms available, and more … [Read more...]
“The Role of the EU ETS in Decarbonisation to 2030” [Energy Post event video]
Here you can watch our video of the online discussion from March 19th 2021 on the current debate over the review of the EU ETS. Of primary concern for fossil-dependent lower income nations is the carbon price rising so high that it reduces available budget for investment in clean energy. If that happens there’s clearly a problem. The counter argument is that there are other funding mechanisms available, and more than one pathway for successful … [Read more...]
How to keep winter ice off a Wind Turbine’s blades
Nearly 800GW of wind power have been installed worldwide so far, with plenty more to come. But the Texas freeze in February showed how vulnerable wind turbines are to ice. Hui Hu at Iowa State University summaries his team’s research into solving a problem that can cut generation by 20% or even shut down turbines completely. He explains why existing de-icing solutions for airplane wings offer only a partial solution. Metal airplane wings can be … [Read more...]
Saudi Arabia’s clean hydrogen plans for converting ambitions into action
The recent Memorandum of Understanding with Germany on clean hydrogen cooperation underlines Saudi Arabia’s ambition in becoming a global powerhouse producer in this field. Governments and industry players are currently considering clean hydrogen as an energy vector with key energy transition roles in an increasingly carbon-constrained world. Hydrogen has the potential to grow into a trillion-dollar commodity market, with enormous opportunities … [Read more...]
Do government renewable energy auctions squeeze the PPA market?
Spanish government renewable energy auctions in January produced record-breaking low strike prices for both wind and solar. For solar the average price was €24.47/MWh (the lowest was €14.98/MWh), guaranteed for 12 years through contracts-for-difference (CfDs). As such auctions continue around Europe, Michael ClauĂźner at Energy Brainpool asks what impact these prices will have on future power prices in general and on solar power purchase agreement … [Read more...]
Denmark approves artificial island to site 10GW Offshore Wind hub
Denmark has approved a plan to build an artificial island in the North Sea that will be a hub to hundreds of offshore wind turbines, 260m tall, that will generate 10GW, enough energy for 10 million households. The first stage will be the size of 18 soccer pitches, for 3GW, costing €29bn ($34bn), and should be operational by around 2033. Writing for the World Economic Forum, Douglas Broom says that the ultimate goal of 10GW should be more than … [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...]
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...]
Essential energy transition metals: “Eco-friendly” trawling of ocean floor could replace land mining
The availability of metals for raw materials has a make-or-break impact on the future of EVs, wind turbines and many other energy sector applications. The world needs 3bn EVs and 10tn kWh/yr more clean energy by 2040 to have any chance of achieving our climate goals. We need so much more that recycling what we already have won’t make a noticeable difference. Mining on land already has very serious negative environmental and social consequences. … [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...]
