Engineered for impact

With a strong record of reliability, low maintenance, and built-in safety, the HyLYZER 500 is the ideal solution for clean hydrogen production in outdoor environments.

Proven technology + track record

Our platform is built on over 20 years of PEM experience and has accumulated more than 500,000 operational hours. Since 2015, more than 45 units have been in operation, and we have continuously validated the product through customer feedback.

Containerized for outdoor use

Our platform is a full-turnkey solution that offers simplified project management, fast deployment, and a low total installed cost (TIC). The containerized design enables easy transport and plug-and-play installation, thereby reducing the need for extensive site preparation.

Comprehensive safety compliance

ISO 22734 compliant with an ATEX-proof enclosure, the HyLYZER 500 also has ASME/PED certified pressure systems and has undergone a cybersecurity assessment. It has been successfully deployed in high-demand sectors, including oil and gas.

High system efficiency

The HyLYZER 500 delivers one of the best efficiencies on the market at 53.2 kWh/kg, which significantly reduces the levelized cost of hydrogen (LCOH), all while delivering superior performance.

Operational flexibility

Wide dynamic operating range (7-100%) with ultra-fast response times, perfectly suited for renewable energy integration and variable power input such as wind and solar.

30-bar pressurized output

High-pressure hydrogen delivery at 30 bar eliminates the need for compression equipment, reducing system complexity and operational costs.
