Their assessment of our energy storage: clean fuel technology, using renewable energy, for decarbonising return to base logistics fleet vehicles, will provide ITM Power with useful data from another vital sector in the global economy."

Dr Martyn Kenny, Head of Sustainability at Tarmac said: "There is an urgent need for the construction industry to reduce the carbon footprint of its vehicles and Tarmac recognises the importance of testing the viability of emerging alternative fuels. These important trials will help us assess the feasibility of decarbonising vehicle fleets using hydrogen derived from renewable energy."
