A trial in Cumbria has tested the blending of hydrogen into the UK national gas network.
Over the last 12 months, the trial scaled from a 2% blend of hydrogen with natural gas up to 100%.
The results show it is safe and effective for the network.
The FutureGrid project, run by National Gas, tested hydrogen blending in previously operational assets from the 5,000-mile national transmission network.
The trial found no issues during phase one and identified no major obstacles to repurposing the network for hydrogen.
The government is assessing a decision on transmission blending.
The FutureGrid project provides data to support this decision.
National Gas aims to support hydrogen production growth and ensure network operability with the EU at minimal cost.
The trial results align with the European Commission’s plan for hydrogen blending, which is expected to expand after 2025.
The UK Government has also pledged £500 million to support green hydrogen manufacturing.
The project has now entered phase two, which will investigate the challenges of compressing hydrogen using existing assets, showing the potential to repurpose gas turbines for hydrogen use at compressor stations.
It will also explore deblending, demonstrating the separation, purification and compression of hydrogen for transportation.
Jon Butterworth, Chief Executive Officer of National Gas, said: “Today’s report presents a promising picture on hydrogen blending, which can help the government meet its ambition of making the country a clean energy superpower as we progress to 100% green hydrogen, and all while using our existing infrastructure.
“We look forward to discussing the findings of phase one of this project with the government and working closely with it to drive forward hydrogen production across the UK, helping to deliver our net zero ambitions.”
