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.
What is hydrogen fuel cells
500
requires utilities to buy power from whatever its using it from
What is a feed in tariff?
500
the amount of input
slight differences in speed yield?
500
geothermal pumps that are in the ground
What is ground source heat pumps?
500
electricity splits hydrogen from water
What is electrolysis
