SUCCESS FOR HYDROGEN BLEND TRIAL AT LINCOLNSHIRE POWER STATION
A successful 2% green hydrogen gas mixing trial has been successfully completed at the Briggs power station in North Lincolnshire. This is said to be the first occasion in which a green hydrogen and natural gas blend has been transported through infrastructure to power electrical generation in the UK. The trial was carried out by Centrica and British Gas to demonstrate the feasibility of hydrogen gas blends into existing UK infrastructure.
Across Europe, several other separate hydrogen trials involving gas blending are ongoing in countries such as The Netherlands, Germany and Portugal. Further details on each trial has been released in a report by the European Clean Hydrogen Alliance in April 2025 titled: ‘Hydrogen-readiness of gaseous fuels distribution infrastructure and heating technologies in Europe’.
The first trial refers to ‘Hydrogen City’, a project located in Stad aan ‘t Haringvliet, in The Netherlands. The local community has voted to stop using natural gas as a primary fuel and will instead use locally sourced green hydrogen. By 2030 at the latest all existing gas infrastructure will be repurposed to transport hydrogen into every domestic and commercial property within the municipality.
Portugal’s leading gas operator, Floene, has begun a 12% green hydrogen natural gas blend project in Seixal, a city near Lisbon. Newly constructed infrastructure will carry green hydrogen to the local transmission network where a blended mix of green hydrogen and natural gas will be fed to 80 residential, commercial and industrial end users. By 2030, the Portuguese government is aiming to provide a 15% green hydrogen natural gas mix in all domestic supplies.
A German project – H2Direkt – is led by energy providers Energie Sudbayern, Energienetze Bayern and utility consultants Thuga. Ten private households and one commercial customer have been receiving 100% hydrogen since 2023 in the Bavaria region. The original test schedule finish date has been extended recently and will go beyond the current year. Initial results indicate that even when exposed to temperatures of -15°C the entire hydrogen infrastructure and hydrogen heating systems were reliable. www.rinnai-uk.co.uk
