Like its alkaline alternative, the CompassH2-P combines Nel’s stack technology with a Samsung E&A system-level design to produce 30-bar hydrogen.

The South Korean EPC firm said the plant design would be optimised for handling renewable energy load fluctuations and could ease project development.

The alkaline CompassH2-A was launched in May, claiming to offer the “world’s most efficient” alkaline solution.

No details on either plant’s capex or system-level performance have been disclosed.

Both systems come after Samsung E&A became Nel’s largest corporate shareholder and EPC partner to sell complete plants based on the Norwegian OEM’s technology.

Samsung E&A President and CEO Hong Namkoong said the PEM plant launch was an important milestone for the mid-to-long-term partnership with Nel.

“We plan to fully advance into the global hydrogen market,” he said.

Modular, factory-built designs are gaining traction across the sector as OEMs seek to cut complexity and costs.

Other electrolyser players like Longi, Electric Hydrogen, and ITM have launched large-scale standardised plants aimed at cutting EPC costs.
