The hydrogen rainbow
Hydrogen power is an exciting technology that is likely to be vital for us to achieve a low-carbon or net-zero society. Hydrogen energy is stored in fuel cells, providing us with a clean source of power which is already being used in some vehicles. The production of hydrogen itself, however, can be done using energy from different sources – including […]
