Green light for green hydrogen on major construction project

Green hydrogen supplied by a UK-based energy company will be used to power plant and temporary power units during the construction of a major rail electrification scheme in the North of England.

More than 2,500 tonnes of low carbon hydrogen are expected to be deployed over the course of the project, replacing millions of litres of diesel. Project leaders estimate the move could prevent around 30,000 tonnes of carbon emissions during the construction phase.

The rail upgrade, spanning approximately 23km, will modernise key commuter and freight routes while supporting regional growth. Construction is scheduled to begin later this year, with completion targeted before the end of the decade.

Hydrogen-powered generators are already being trialled on enabling works, with full deployment planned as main construction ramps up. The hydrogen will be supplied as a managed service, including on-site storage, refuelling and system monitoring to ensure reliability across multiple work sites.

Matt Palmer, executive director for the Lower Thames Crossing, said: “Today we’ve given the green light to green hydrogen. By replacing diesel with home-grown hydrogen, we're not only reducing our own carbon footprint but also helping clean up the construction sector.”

The hydrogen will be produced using renewable electricity, ensuring that lifecycle emissions are significantly lower than conventional fuels. Production sites have been strategically located to support regional demand and minimise transport distances.

Industry analysts suggest that contracts of this scale signal growing confidence in hydrogen as a viable construction fuel. The requirement for hydrogen-compatible equipment is also expected to stimulate investment from plant manufacturers and rental providers, helping accelerate market readiness.

The initiative aligns with wider national ambitions to expand domestic hydrogen production, strengthen energy security and reduce reliance on imported fossil fuels.
