The possibility of hydrogen-powered flight means greater opportunities for fossil-free travel, and the technological advances to make this happen are moving fast. New studies show that almost all air travel within a 750-mile radius (1200 km) could be made with hydrogen-powered aircraft by 2045, and with a novel heat exchanger currently in development, this range could be even further.
A novel heat exchanger and a new type of fuel tank will (they say) convert existing aircraft for burning liquid hydrogen fuel. It isn’t balloons.
Cool!
