No matter how far batteries come, were always likely going to need some form of hydrocarbon fuel for industries like aviation. Exciting to see research done in this area! I wonder how the theoritia efficiency of a technology like this compares to the efficiency of using centralized production of electricity using wind and solar followed by centralized production of hydrocarbons in a reactor offsite? Especially if the hydrocarbons are produced from electricity right near the airport so that transport costs are for transporting electricity instead of the fuel?
