A high-tech sponge can absorb water vapor from the air and convert it to pure hydrogen for use in hydrogen fuel cell vehicles and machines.
This sponge uses electrolysis to extract pure hydrogen and can be powered by solar or wind energy, producing renewable fuel from renewable electricity.
The only portable green fuel source that could replace diesel or kerosene at scale, pure hydrogen is not abundant in nature, and finding ways to produce it sustainably is the key to expanding its use in industry and transportation.
Vehicles can be equipped with …
