Classifying unabated gas-fired power plants as “transitional investments” – as in the EU taxonomy proposal – attracts financial and utility investors. As it stands, both will be able to increase their corporate “green scoring” by investing in gas, including outside Europe. The CO2 cap for new power plants build by 2030, meanwhile, paves the road for hydrogen co-firing.
Capturing carbon emissions directly from the air requires a lot of electricity, hence the German government prioritises the renewable build-out. “Carbon Capture and Utilisation (CCU) with direct air capture should only be used once renewables have reached a share of more than 80% of power supply,” analysts at the Federal Environment Agency (UBA) stressed.
JERA and Mitsubishi Heavy Industries (MHI) have received Japanese government funding to develop a novel technology that will increase the rate of ammonia co-firing at boilers in thermal power stations. Burning ammonia is carbon-free and the JERA-MHI team vowed to verify co-firing with at least 50% ammonia at two different boiler types by 2028.
Honeywell has entered a licensing arrangement with University of Texas at Austin to utilize the latter’s new Advent Solvent technology to capture CO2 more efficiently. Carbon pricing accelerates retrofits in the power sector and Honeywell says applying advanced solvent CCS to a typical 650 WM plant allows to capture about 3.4 million tons of CO2 annually.
ESG Clean Energy has applied for new patents on capturing CO2 from small-scale gensets while producing water or recycled plastic. The US-based company is about to complete its first 4.2 MW plant that utilizes these technologies to feed electricity into the local grid and provide distilled water from the carbon by-products.
Oxford-based NGO Carbon Gap has urged governments in Europe and the UK to support the scale-up of technologies that can remove CO2 directly from the air. Researchers highlight the strong need to invest in R&D for carbon removal, provide deployment incentives and develop standards and clear target to incentivise utilities to start delivering net-negative emissions.
