LANXESS ion exchange resins applied in hydrogen production

Lewatit UltraPure for water treatment in PEM electrolysis

  • By ICN Bureau | April 15, 2024

LANXESS has developed special ion exchange resin grades within its Lewatit UltraPure range that can be used for water treatment in PEM electrolysis (Proton Exchange Membrane Electrolysis). This process, which converts electricity from preferably renewable energies into hydrogen, is regarded as a promising approach to the sustainable production of this precious gas.

Experts believe that PEM electrolysis will play an important role in the transition to a hydrogen-based economy. Compared to alkaline electrolysis, the high current density of PEM electrolysis allows hydrogen to be produced in smaller systems. Another advantage: hydrogen filling stations can be connected directly to the high-pressure outlet.

LANXESS’s Liquid Purification Technologies (LPT) business unit is in talks with renowned gas producers to establish standards for efficient water treatment in PEM electrolysis plants.

Hans-Juergen Wedemeyer, Technical Marketing Manager at LPT, explained: “Our technical expertise, combined with our high-performance ion exchange resins, support the water purification process for systems. Preliminary application test results enable the plant conditions to be simulated and the state-of-the-art Lewatit UltraPure ion exchange resins to be optimally used. LANXESS is thus supporting a sustainable, climate-friendly energy supply.”
