Green hydrogen

Utilising green hydrogen as a source of demand for low carbon electricity and a source of flexible power

About green hydrogen


Low carbon electricity can be used to convert water to hydrogen – a low carbon fuel that can be stored for long periods and used as a flexible power source. This can help to decarbonise industry and transport in areas where electrification isn’t possible. Green hydrogen will play a central role in supporting the transition to a renewables-based energy system by providing both a source of demand for low carbon electricity and a source of flexible power.


In 2023, the UK awarded the first H2 production contracts through the first Hydrogen Allocation Round (HAR1), with the ambition to deliver at least 5GW of capacity by 2030. For the green hydrogen industry to grow, it’s critical that we address barriers for projects contributing to tangible decarbonisation. We must find a way of providing wider system benefits that offer value for money for Government, industry and consumers.

RenewableUK runs the following working group with its members on green hydrogen.


Green hydrogen working group


Green hydrogen will play a central role in supporting the transition to a renewables-based energy system, by providing both a source demand for low carbon electricity and source of flexible power. This working group will address barriers to deployment, the building of associated infrastructure and identify interface issues between renewables and electrolysers.
