Hydrogen is the single most abundant chemical element in the universe. Although present on Earth, it does not occur in large enough quantities to be captured cost-competitively. Therefore, in order to harness the power of hydrogen, it needs to be extracted from hydrocarbons or water.
There are several ways of manufacturing hydrogen. A colour coded system defines the production method and/or the energy source used for production, and to what extent they impact the environment. Currently, 96% of the world’s hydrogen is made from fossil fuels, accounting for a carbon footprint of 830 million tonnes per year.
Using just water and renewable energy, our PEM electrolysers produce the only truly clean kind of hydrogen – green. The only by-products are water vapour and oxygen, the latter being utilised in other industries, or vented into the atmosphere with no negative impact.
