The UK Government is actively considering introducing hydrogen blending into the national gas network as part of wider decarbonisation efforts. According to energy minister Michael Shanks, a formal decision is expected shortly following an evidence-gathering phase assessing the impact on consumers and infrastructure.
Blending up to 20% hydrogen with natural gas is technically feasible with most existing boilers and appliances in domestic and commercial settings. Gas network operators have indicated that current infrastructure could handle such a mix without significant modifications, offering a transitional path toward lower-carbon heating.
Scotland is leading several green hydrogen production projects to leverage the country’s renewable energy capacity. Recent developments include a large-scale hydrogen facility approved in Kintore, Aberdeenshire, and discussions around the Grangemouth industrial site as a potential hydrogen hub.
While hydrogen presents a cleaner alternative to natural gas, its lower energy density requires greater volumes to produce the same heat output. This raises ongoing questions about the viability of a 100% hydrogen gas grid for domestic use.
