UK’s first hydrogen heating demonstration takes place

Boiler manufacturers Baxi Heating and Worcester Bosch have installed hydrogen burning boilers at ‘HyStreet’, in specially built demonstration houses at DNV GL’s specialist test site at Spadeadam in Northumberland.

The site has been used to complete over 200 tests, researching and proving the safety of converting homes and gas networks to hydrogen.

The project is part of H21, a Network Innovation Competition project sponsored by Ofgem. Northern Gas Networks is leading the project with partners Cadent, Scottish Gas Networks, Wales & West Utilities, National Grid, DNV GL and the Health and Safety Executive’s science division. H21 is demonstrating how existing natural gas networks can be repurposed to safely carry 100% hydrogen.

For the first demonstration both Worcester Bosch and Baxi Heating have installed combi boilers into the houses on HyStreet. The boilers have been developed as part of the UK Government-funded Hy4Heat programme, which is also supporting the development of hydrogen-ready gas cookers, fires and gas meters.

Karen Boswell, managing director of Baxi Heating, said: “This is an important step forward on our hydrogen journey and we are delighted to be able to demonstrate this innovative new technology in a real life setting in the UK.”

Carl Arntzen, CEO of Worcester Bosch, added: “It is fantastic to see our prototype hydrogen boiler running successfully at this demonstration site. The boiler has operated seamlessly in its first month of operation and continues to provide both heating and hot water.

“It proves that hydrogen gas has great potential as a zero-carbon alternative to natural gas for heating and hot water in the UK and beyond. These initial tests are incredibly encouraging and will hopefully give key decision makers confidence to deploy hydrogen gas as a fuel for the future.”
