Veolia Water Technologies UK (VWT UK) is supplying water treatment systems to global water electrolyser manufacturers as part of the water treatment specialist’s movement into the hydrogen production market.
VWT UK’s systems can be fed with reservoir, river, borehole or saline feed water to produce water suitable for feeding PEM electrolysers.
Water electrolysis has a key role to play in the production of hydrogen. To ensure efficient water electrolysis, only high purity deionised feed water must be used to prevent impurities from concentrating inside the electrolyser, which can adversely affect the performance of the electrode and diaphragm surfaces.
Failure to meet deionised water requirements not only leads to faster system deterioration, but also a reduction in system performance.
