UK Road Project Locks in Record Green Hydrogen Deal

A massive British infrastructure project just made history by securing the largest green hydrogen contract ever signed for construction in the UK.

The Lower Thames Crossing, a new road and tunnel connecting southeast ports to the Midlands and North, will run entirely on hydrogen, electric, and low-carbon fuels instead of diesel. GeoPura, a British hydrogen company founded just six years ago, will supply 2,500 tonnes of green hydrogen to power the entire construction phase.

That's enough clean fuel to replace over 12 million litres of diesel and prevent 30,000 tonnes of carbon dioxide from entering the atmosphere. Unlike diesel engines that spew harmful emissions, hydrogen fuel cells release only water vapor, keeping the air clean for construction workers and nearby communities.

GeoPura produces its hydrogen at HyMarnham Power in Nottinghamshire, a facility built on the site of a former coal-fired power station. The company uses renewable electricity to split water molecules through electrolysis, creating hydrogen fuel without any carbon emissions. Six hydrogen generators are already charging batteries for electric machinery at a work site in Essex with zero pollution.

The project achieved another milestone last year when a British-made JCB hydrogen digger became the first of its kind deployed outside testing anywhere in the world. The machine completed survey work in Kent, proving the technology works in real construction conditions.

The Ripple Effect

This single contract is transforming Britain's entire construction industry. Three of Europe's biggest construction firms must now invest in hydrogen-powered machinery and train their teams to operate the new equipment. That investment will speed up the whole sector's shift toward carbon-neutral building.

The green hydrogen industry could create over 400,000 jobs and add more than £7 billion to the British economy by 2030. GeoPura already employs over 170 people across Britain and Europe, many who previously worked in traditional fossil fuel industries and successfully transitioned to clean energy careers.

The Lower Thames Crossing received planning permission in March 2025 after years of preparation. The project will ease traffic congestion on the overcrowded Dartford Crossing while creating reliable new connections between major ports and industrial regions. Government funding secured in last year's budget will enable private companies to complete construction and manage long-term operations.

Minister for Industry Chris McDonald celebrated the collaboration as proof that major infrastructure and clean energy work perfectly together, powering British projects sustainably from Nottinghamshire to Kent.

One construction contract just showed the world how to build big without breaking the climate.
