Green hydrogen

Pure water for generating green hydrogen

Green hydrogen is generated through the electrolysis of water, in which it is broken down into oxygen and hydrogen. Both the production and combustion of this gas are CO2-free. Many experts view green hydrogen as an energy source for the future in the areas of industry, heat supply and mobility.

Generating green hydrogen through electrolysis requires a reliable supply of pure water, sometimes in great quantities. EnviroChemie’s experts develop custom plant solutions for water treatment and polishing based on customer requirements.

Ultrapure water is also needed when generating other gases, such as green ammonia. For such applications, we plan customised water treatment systems, build them and commission them on your behalf.

Ensuring the availability of high water qualities – rely on our experience

When producing green hydrogen, various water sources can be used for feed water treatment: sea water, river water, surface water or wastewater. We use a range of different technologies and combinations of technologies to reliably supply water in the high qualities required, even for applications such as water recycling (polishing):

• Physico-chemical process
• Membrane technology such as ultrafiltration or reverse osmosis
• Electro-deionisation
• Multi-stage ion exchanger plants
• Regeneration of ion exchange resins (separated into individual resin types) on site or through our service, in which we regenerate the resins for you and provide you with freshly prepared resins in a fast, reliable and convenient process.
