Hydrogen has an important role to play in decarbonising shipping and aviation, but parts of the transport industry want more clarity from Government about the intended role of hydrogen since there are significant infrastructure requirements and substantial costs that need to be met. There are also significant infrastructure requirements associated with hydrogen deployment in aviation and shipping but the likely ‘winner’ from amongst the potential low-carbon technologies in these sectors has yet to emerge and the choice will be internationally, rather than domestically, determined. In its response to this Report, the Government should set out its strategy for participation in international fora to shape a global outcome on the role of hydrogen in shipping and aviation.
