Hydrogen. Some believe it a wonder fuel touted with decarbonising energy-intensive areas of the world’s industrial or transport economy. Others focussed on the off-grid space view it as an energy carrier, capable of storing and transporting energy generated by renewables and delivering that energy to off-grid locations via existing road infrastructure.

Viewed like this, hydrogen becomes a good Net Zero replacement fuel for diesel, especially diesel used in generators. The benefit for construction and infrastructure projects is difficult to ignore, especially if the hydrogen generator used on-site is a fuel cell.

Fuel cells produce only water as a waste product, meaning that there are zero CO2e or NOx emissions at point of use, whatever colour of hydrogen used as a fuel.

But how do end users like Kier access this solution?

What carbon impact could adopting hydrogen have in the real world?

And what operational impact would it have to current and future projects?
