What sets it apart

Producing high-purity hydrogen at 30 bar without compression, our HyLYZER 1000 electrolyzer systems are the most efficient and compact solution on the market.

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 2020, more than 20 units have been in operation at industrial sites, and we have continuously validated the product through customer feedback.

Exceptionally compact design

Its industry-leading, compact, and modular design reduces land use, building costs, and integration complexity. It is skid-mounted for easy transport (only two trucks are needed per HyLYZER 1000 module) and requires minimal on-site assembly.

Comprehensive safety compliance

Our electrolyzer system is ISO 22734 compliant and has an ATEX-proof enclosure. It also has ASME/PED certified pressure systems and has undergone cybersecurity assessment. It has been successfully deployed in high demanding sectors, including oil and gas.

High system efficiency

The HyLYZER 1000 offers the best efficiency in the market, significantly reducing energy costs and levelized cost of hydrogen (LCOH), while delivering superior performance.

30-bar pressurized output

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

Operational flexibility

Wide dynamic operating range (15-100%) with ultra-fast response times, perfectly suited for renewable energy integration and variable power input.
