In the forthcoming period, PEM electrolyzers are likely to dominate green hydrogen production due to their ability to produce high-purity hydrogen gas (99.999%), essential for applications like fuel cell vehicles. High purity water is crucial for maintaining electrolyzer function, and inadequate water treatment can cause damage. The choice of electrolyzer technology and water source determines the required water treatment. FEDI® is an optimal solution for this application.
Since its commissioning in 2024, QUA’s FEDI® technology has reliably delivered type 2 purified water with a conductivity of 0.1 μS/cm, meeting the stringent purity requirements of green hydrogen production. QUA’s FEDI® supports sustainable hydrogen production and contributes to global efforts for a greener future.
