National Highways Pioneers the Hydrogen Revolution for Lower Thames Crossing

National Highways is taking a major step towards sustainability by making hydrogen the main energy source for the Lower Thames Crossing. This project aims to be the first major UK infrastructure development powered by hydrogen, cutting emissions from construction vehicles and heavy machinery.

Why Hydrogen?

By switching to hydrogen-powered equipment like excavators and dump trucks, National Highways plans to replace 20 million litres of diesel. Hydrogen produces only water as a byproduct, reducing carbon emissions and supporting the UK’s move to cleaner energy.

Beyond just using hydrogen, National Highways plans to build a full hydrogen supply network in the Thames Estuary. This includes producing, storing, and distributing over 6,000 tonnes of hydrogen, potentially benefiting local industries and communities.

Other Clean Energy Solutions

For machinery that can use electric power, National Highways will rely on renewable energy sources. Battery-powered equipment will also be introduced where suitable, further reducing reliance on fossil fuels.

Challenges and Criticism

Despite its green ambitions, the project has faced criticism from the Thames Crossing Action Group, which accuses National Highways of "greenwashing." To build trust, National Highways must demonstrate real progress and transparency in its sustainability efforts.
