There are some benefits to using hydrogen as a fuel: 1  unlike petrol and diesel, hydrogen does not generate carbon dioxide when burnt. 2  hydrogen fuel cells are very efficient.
Hydrogen fuel cells power the shuttle's electrical systems, producing a clean byproduct-pure water, which the crew drinks. A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water. Fuel cells are often compared to batteries. Both convert the energy produced by a chemical reaction into usable electric power. However, the fuel cell will produce electricity as long as fuel (hydrogen) is supplied, never losing its charge.
