Overall, whilst there are a variety of possible applications of hydrogen technology across every sector of the UK economy, we agree with the Government that on the basis of present knowledge and the technology available it seems that the role of hydrogen will be to decarbonise specific, limited areas where electrification is either not possible or clearly not optimal, such as the industrial clusters currently developing hydrogen capabilities. The clusters may also offer a future production option for some of the hydrogen required in other applications. The Government should prioritise the use of hydrogen in those sectors where there is a genuine prospect of technical, feasible and economically viable deployment. The Government should work closely with businesses and international partners to set, in the 2020s, a realistic strategy for the adoption and use of hydrogen in these sectors.
