In June, The White House issued its 250-page report on the global critical minerals supply chain, and how the U.S. can ensure continued supply as well as build up its own mining and manufacturing base. It is the fullest picture so far of how the U.S. is evaluating mineral access and supply chain resilience, says Reed Blakemore at the Atlantic Council Global Energy Center. Here he reviews the report, in particular the section on energy which … [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...]
Grid scale Battery costs are declining faster than Wind and Solar
Gas as a transition fuel for grids may be around for a lot less time than we thought. We already know that large batteries, if they are cheap enough, can replace gas plants to provide peaking power to grids reliant on intermittent wind and solar. Bruce Robertson at IEEFA says the numbers are showing battery costs declining even more rapidly than wind and solar. Precisely because of that increased competitiveness Australia’s AGL Energy is starting … [Read more...]
2019’s grid storage additions fell for the first time since 2013. Why?
Globally, new installations of grid storage fell year-on-year in 2019 for the first time since 2013. This IEA summary of the landscape is taken from its latest series of Tracking Clean Energy Progress reports. The IEA’s recommendations reflect the fact that grid storage is new and complex, needing changes to existing regulations and market rules that are unviable in the age of transition. The policy goal is to monetise the value of storage in … [Read more...]
Grid Battery tech on track. It now needs re-designed markets, monetisation
The rapid expansion of variable renewable electricity generation is making cost effective storage more urgent. Sure enough, in Europe several electricity storage projects are under construction and new ones are announced almost on a weekly basis. The battery technology seems to be on track, with estimates of $156/kWh in 2019 dropping to $61/kWh by 2030. But progress is hampered by the lack of a market that recognises and rewards the true value of … [Read more...]
Solar farms getting smaller, cheaper and smarter to overcome grid hurdles
The technical challenges and fast-changing regulatory requirements associated with installing and integrating variable RES capacity are inevitably holding up the transition to clean energy all around the globe. So the announcement of a new smart solar farm in Australia that seems to have overcome these hurdles is really good news. The situation has been neatly captured across a number of recent reports (summarised here) by Giles Parkinson of … [Read more...]
