Energy group BP aims to build Britain’s largest hydrogen plant by 2030 as part of its push to boost the use of fuel and cut greenhouse gas emissions. The Teesside plant in northern England will have a capacity of up to 1 GW of blue hydrogen, about a fifth of Britain’s target of 5 GW of hydrogen capacity by the end of the decade. Blue hydrogen is produced by converting natural gas into hydrogen and storing the CO2 emissions from its production.
