PEM Electrolyzer ME450: H-TEC SYSTEMS products

H-TEC PEM Electrolyzer ME450

  • Nominal load: 1 MW corresponds to refueling 90 cars per day
  • Hydrogen production: 450 kg/d
  • A turnkey solution with scalability

Innovative down to the last detail

Innovative down to the smallest detail: The H-TEC SYSTEMS ME450 electrolyzer is the proven turnkey solution to produce green hydrogen. Thanks to a multiple stack design, high availability and excellent spare parts availability, risks can be minimized, and costs reduced. At the heart of the transportable 40 ft container are 9 S450 PEM stacks. With a total electrolysis power of 1 megawatt, they supply enough hydrogen to refuel 90 cars per day. The proven design as well as the dependable spare parts availability make the technology of the ME450 electrolyzer reliable and ready for the future.
