Hydrogen is a very abundant element, which can be produced in an electrolyser using renewable electricity. This converts water into hydrogen and oxygen using the electricity, and the hydrogen gas can then be compressed stored in high pressure cylinders.
- Hydrogen can be used directly in fuel cells, as an alternative fuel in combustion devices such as engines and boilers, or as a chemical feedstock in a number of important industrial processes such as ammonia or methanol manufacture.
- Fuel Cells use an electrochemical process to convert chemical fuels into electricity. The fuel is combined with oxygen from the ambient air to produce electricity, with heat and water as the waste products.
- Unlike batteries, Fuel Cells will continue to generate electricity as long as a source of fuel is supplied.
- Fuel Cells do not combust fuel but use a catalytic oxidation which makes this electricity generation process quiet, pollution-free and more efficient than using internal combustion engine powered generators.
- Hydrogen and Fuel Cells are now playing a key role in developing low carbon smart energy systems with several projects underway in Scotland.
