Nearly one-third of the natural gas used for heating and cooking in the UK could be replaced by hydrogen without the need to change boilers or ovens, researchers have suggested.

Adding 30% hydrogen to the gas grid could cut the UK’s carbon dioxide emissions by 18%, according to a paper by Swansea University.

Hydrogen-enriched natural gas is already being used in parts of Germany and the Netherlands.

The UK Government is backing a £600 million trial this year.

Achieving Paris goals

Charles Dunnill, a Senior Lecturer at the Energy Safety Research Institute at Swansea University, said: “As a low-carbon domestic fuel, hydrogen-enriched natural gas can cut our greenhouse gas emissions, helping the UK meet its obligations under the 2016 Paris Climate Change Agreement.

“Hydrogen-enrichment can make a difference now.

“But it could also prove a valuable stepping-stone towards a future, pure hydrogen, zero-carbon gas network.”
