SGN, a gas distribution company in the UK, has successfully installed the world's first domestic hydrogen gas network in Levenmouth as part of its H100 Fife project. The £32 million trial involves an 8.4km pipeline network supplying green hydrogen to homes in Buckhaven and Denbeath. Around 300 households have shown interest, and the project aims to save significant amounts of CO2. The green hydrogen will be produced through electrolysis using electricity from an offshore wind turbine. Residents can switch to hydrogen for heating and cooking, with the project also focusing on upskilling local gas engineers. SGN plans to convert customers to green hydrogen once the production and storage site is operational. The company emphasizes community support and cooperation in delivering this innovative project. While SGN's initiative has a positive outlook, doubts arise regarding the role of hydrogen in home heating due to delays and alternative technologies like heat pumps gaining traction. The project aims to provide critical evidence for future policy decisions, contributing to the ongoing debate on decarbonizing home heating in the UK.
