A fuel cell is an electrochemical energy conversion device that was invented in 1839 by William Grove to produce electricity by combining hydrogen and oxygen into water. Like batteries, fuel cells convert potential chemical energy into electrical energy and generate heat as a by-product. While chemical energy is stored inside batteries, fuel cells can continuously generate electricity as long as they are supplied with fuel (hydrogen) and an oxygen supply.
Watch this video to learn how hydrogen fuel cells produce clean, reliable energy. Fuel cells enable hydrogen and oxygen to react in a chemical process that produces electricity and heat, with pure water as the only by-product. Ruled by the laws of science, the process is ultra-reliable.

Watch this informative video from CNBC to learn how green hydrogen could be key to a carbon-free future. Because hydrogen is a clean-burning molecule, it may help decarbonize hard to clean sectors. If it can surmount some challenges, green hydrogen produced from renewable electricity may be the solution.
Hydrogen as a fuel is a great alternative source of clean and sustainable energy. The lightest and most abundant element in the universe, hydrogen is considered to be the most environmentally-friendly fuel. Nearly 65 million metric tons of hydrogen are produced every year worldwide using a variety of methods, including steam reformation of natural gas, the fermentation of biogas and electrolysis using solar power.
Ammonia (NH3) is the second most-produced inorganic chemical in the world and is safely produced, stored and used when handled properly. It has a high hydrogen density and is a widely-used commodity that costs half the price of diesel. About 80% of ammonia is produced for use in fertilizer. Ammonia is also used as a refrigerant gas, for purifying water supplies, cleaning equipment for producing food, for creating plastics and even in pharmaceuticals. Due to its ability to kill harmful bacteria, ammonia is found in many household and industrial-strength cleaning solutions.
