The Japanese government has announced a $110 million fund that will support two hydrogen research projects aimed at fuel cell propulsion system development that can advance hydrogen aviation. Rethink has already identified Japan as one of the most promising markets for low-carbon aviation due to the country’s size and number of domestic flights, and in this article we will quantify this potential against the present day fleets and routes. Japan also has an active, broader program worth $33 billion aimed at the wider low-carbon aviation sector. One of the two new research projects targets the development of a 4 MW propulsion system fueled by liquid hydrogen for regional aviation by 2029 (led by conglomerate IHI with support from Toray Industries…
