Hydrogen Used to Decarbonise Asphalt Production in UK First

Heidelberg Materials UK completed a pilot at its Criggion plant using hydrogen to heat asphalt production, generating over 1,300 tonnes of asphalt without quality loss. The trial cut direct (Scope 1) emissions by 76 % and lowered the overall carbon footprint by 23%, consuming 4,522 kg of hydrogen and avoiding roughly 25,105 kg of CO₂. If replicated across the sector, the approach could save up to 450,000 t of CO₂ annually. The project is part of the government‑backed Industrial Hydrogen Accelerator programme, highlighting policy interest in low‑carbon heat for heavy industry.
