Compared to Battery Electric Vehicles (BEV), Fuel Cell Electric Vehicles (FCEV) have lagged during the electrification of the road transport sector across the world in the past ten years. Under the new context related to technological competition among economic powers, the energy crisis enhanced by the Russia-Ukraine war in Europe, the global supply chain security of critical materials in BEV manufacturing, as well as the greater role of hydrogen in energy transition, its worthy of re-evaluating the potential of FCEV in accelerating the decarbonization of the transport sector. Professor Gregory Trencher from Kyoto University in Japan shares his research insights on these relevant issues in this episode of Energy Current.
