The research concluded:
It is feasible to build refuelling infrastructure to support the deployment of zero emission HGVs so that they constitute the vast majority of vehicles on the roads by 2050.
Looking at infrastructure alone, deploying hydrogen refuelling stations is the cheapest of the options, costing a total of £1.7bn in capital expenditure in the time period from now until 2060.
When the costs of the fuel as well as the infrastructure are included, the costs of deploying electricity or hydrogen HGVs are cheaper compared to the continued use of diesel.
