Excess electricity generated by offshore wind farms could be used to produce hydrogen for use in heating and cars. Kwasi Kwarteng, the Business and Energy Secretary, is preparing to unveil plans to dramatically increase the use of low-carbon hydrogen as part of the country’s target to reduce net greenhouse gas emissions to zero by 2050. One option being considered by ministers is subsidising the production of the chemical using excess energy generated by offshore wind farms. The hydrogen strategy, due to be published this week, is expected to outline government plans for a “twin track” approach to back both green hydrogen, which is made from water using an electric current, and blue hydrogen, which is made from natural gas. The document will also outline proposals, announced in Boris Johnson’s 10-point plan for net zero, for Britain to have the capacity to generate five gigawatts (GW) of low carbon hydrogen by 2030 – although the paper is expected to fall short of outlining the specific plan to use excess energy from wind turbines to produce green hydrogen. It will instead simply set out “a comprehensive package of support” for “green” projects. The Telegraph has previously revealed how wind farms have been paid millions of pounds a day to switch off their turbines and not produce electricity. Often the “constraint payments” are paid to wind farm operators on windy days when the energy being produced outstrips demand from consumers.
