It is likely that there will be a range of zero emission technologies adopted in the future. The UK is well-placed to be a leader in hydrogen and electric powered transportation.
The Advanced Propulsion Centre (APC) is directed at late-stage R&D to develop important technologies in the transition to zero-emission transport. Hydrogen, including as a fuel for ICE applications, is an important contributor to reducing CO2 and other harmful emissions and is within the scope the APC.
