Ed Miliband, Rachel Reeves and Keir Starmer visit Teesside, the location of a proposed multibillion-pound carbon capture and storage project. Letter says technologies to produce blue hydrogen and capture CO 2 are unproven and could hinder net zero efforts Leading climate scientists are urging the government to pause plans for a billion pound investment in “green technologies” they say are unproven and would make it harder for the UK to reach its net zero targets. Labour has promised to invest £1bn in carbon capture, usage and storage (CCUS) to produce blue hydrogen and to capture carbon dioxide from new gas-fired power stations – with a decision on the first tranche of the funding expected imminently. However, in the letter to the energy security and net zero secretary, Ed Miliband , the scientists argue that the process relies on unproven technology and would result in huge emissions of planet-heating CO 2 and methane – gases that are driving the climate crisis. “We strongly urge you to pause your government’s policy for CCUS-based blue hydrogen and gas power, and delay any investment decision … until all the relevant evidence concerning the whole-life emissions and safety of these technologies has been properly evaluated,” they write. The letter , which is signed by leading climate scientists from the UK and US as well as campaigners, argues the plans would: Lock the UK into fossil fuel production for generations to come. Result in huge upstream emissions from methane leaks, transport and processing of liquefied natural gas (LNG) from the US. Rely on carbon capture and storage (CCS) during the production of hydrogen – technology they say has been abandoned in the vast majority of similar projects around the world. Pose a danger to the public if there are any leaks from pipes carrying the […]
