Samsung E&A has unveiled its latest green hydrogen production system, the CompassH2-P, developed in partnership with Nel Hydrogen.
The 100 MW proton exchange membrane (PEM) electrolyzer marks the company’s first foray into PEM technology, complementing its earlier alkaline system, CompassH2-A, launched earlier this year. The new solution produces high-pressure (30 bar) and ultra-pure (99.9995%) hydrogen, while its optimized stack and balance-of-plant design reduces plant footprint—an increasingly important factor in large-scale hydrogen projects.
The CompassH2-P is positioned as a versatile solution for renewable-based hydrogen production, capable of managing the load fluctuations typical of solar and wind generation. Samsung E&A’s approach combines plant engineering, procurement, and construction (EPC) capabilities with an integrated performance guarantee—a model designed to enhance bankability and investor confidence. By offering both alkaline and PEM platforms, the company aims to provide customized configurations for different operational contexts: cost-efficient base-load production via alkaline electrolysis, and dynamic, renewable-linked flexibility through PEM technology.
The system’s high-pressure output allows for easier integration into downstream applications such as refueling infrastructure and industrial processes, potentially reducing the need for additional compression or purification equipment. While Samsung E&A has not disclosed cost metrics, the company positions CompassH2-P as a step toward more modular, efficient, and scalable hydrogen plants. Analysts note that the technology’s competitiveness will depend on long-term performance, efficiency, and its ability to deliver consistent output under variable power input.
The launch of CompassH2-P signals Samsung E&A’s intention to compete in the next phase of hydrogen development, where full-system integration and cost efficiency will define market leadership.
