Heidelberg Materials Trials Hydrogen for Decarbonizing Asphalt Production in UK
Heidelberg Materials conducted a trial at its Criggion plant in Powys, Wales, using hydrogen to replace fossil fuels in asphalt production. The project, part of the UK's Industrial Hydrogen Accelerator programme, achieved a 76% reduction in Scope 1 emissions and a 23% decrease in the carbon footprint of over 1,300 tonnes of asphalt produced. The trial consumed 4,522kg of hydrogen, saving approximately 25,105kg of CO₂, with potential industry-wide savings of 450,000 tonnes of CO₂ annually if adopted widely.

Heidelberg Materials has successfully trialed hydrogen as an alternative to fossil fuels for asphalt production at its Criggion plant in Powys, Wales. The trial, part of the UK Government's Industrial Hydrogen Accelerator programme, lasted three years and resulted in over 1,300 tonnes of asphalt produced with no quality or performance issues.
It achieved a 76% reduction in Scope 1 emissions and a 23% reduction in the overall carbon footprint. A total of 4,522kg of hydrogen was consumed, saving about 25,105kg of CO₂. If scaled across the UK asphalt industry, annual CO₂ savings could reach 450,000 tonnes. The initiative highlights hydrogen's potential in decarbonizing heavy industry.
