UK Achieves Landmark Hydrogen Blending Trial in Gas Grid
In a groundbreaking step toward a low-carbon energy future, British energy companies have successfully injected green hydrogen into the UK’s gas grid for the first time, using it to generate electricity at the Brigg power station in North Lincolnshire.
The trial involved a 2% blend of renewable hydrogen mixed with conventional natural gas, marking the UK’s first “real-world” test of hydrogen in the national gas system. While hydrogen blending has been previously tested in controlled environments and decommissioned pipelines, this is the first instance where it has been applied in the operational gas network.
The project was led by Centrica, parent company of British Gas, and National Gas, the operator of Britain’s gas transmission system. By using existing gas infrastructure, the trial demonstrates how hydrogen can be seamlessly integrated into the energy system, helping to decarbonise electricity generation while utilising the country’s existing pipeline network.
Green hydrogen is produced by splitting water with renewable electricity, resulting in minimal carbon emissions. Its application in the gas grid offers a promising solution for decarbonising industries and sectors where other low-carbon alternatives, such as heat pumps, may be less viable.
“This trial is a significant milestone for the UK’s energy transition,” said Gary Smith, General Secretary of the GMB union. “It highlights the role of innovation in creating skilled, sustainable jobs across our industrial heartlands, and demonstrates how clean energy can support both climate goals and local communities.”
Jon Butterworth, Chief Executive of National Gas, added: “This success proves that hydrogen blending can fuel power stations and unlock new investment opportunities for hydrogen producers. By leveraging our existing infrastructure, we are powering the next era of clean British energy. Working alongside government and industry, we are proud to lead the effort to make hydrogen a cornerstone of the UK’s energy system.”
Following the successful trial, Centrica and National Gas are calling for government support to expand hydrogen blending to 5% across the gas network, potentially accelerating the adoption of low-carbon hydrogen throughout the country.
The trial represents a major step forward for the UK hydrogen economy, showcasing how renewable hydrogen can reduce carbon emissions, support sustainable industrial growth, and position the nation as a leader in clean energy innovation.
