Samsung E&A, a total solutions provider for the global energy industry, has partnered with Nel ASA to launch CompassH2-A+, a 100 MW pressurized alkaline electrolysis solution, at the World Hydrogen Summit in Rotterdam. The launch marks the third addition to the CompassH2 portfolio, which now includes atmospheric alkaline, pressurized alkaline, and Proton Exchange Membrane (PEM) electrolysis technologies. With this expanded lineup, the partnership aims to offer flexible hydrogen production solutions tailored to diverse project requirements.
Compact Design Reduces Footprint and Compression Costs
CompassH2-A+ is built around Nel’s pressurized alkaline electrolyzer technology, configured in containerized 25 MW stack modules. The modular and compact architecture reduces plant footprint requirements by nearly 50 percent compared to conventional systems currently available in the market. In addition, the system produces hydrogen at 15 barg pressure, significantly lowering the cost and complexity of downstream compression infrastructure.
The standard 100 MW configuration is capable of producing approximately 40 tons of hydrogen per day at 99.999 mol-percent purity. The system also delivers a stack efficiency of 48.8 kWh/kg, all within a compact core footprint of only 7,500 square meters.
Integrated Guarantee Structure Simplifies Project Financing
Beyond the technology platform, Samsung E&A has introduced a comprehensive wrap guarantee that covers the full integrated system, including electrolyzer stacks, Balance of Plant (BoP), and utility systems, under a single performance commitment and counterparty structure.
The company said this approach directly addresses one of the key challenges faced by hydrogen developers and lenders — fragmented guarantee arrangements that often complicate project financing and risk assessment.
To further strengthen long-term project reliability, the solution includes a Long-Term Service Agreement (LTSA) covering operational support, scheduled stack replacement, and real-time performance monitoring throughout the plant lifecycle.
Pre-Engineered Solution Accelerates Project Development
Samsung E&A highlighted that CompassH2-A+ has been developed as a pre-engineered solution, enabling developers to significantly reduce Pre-FID (Final Investment Decision) timelines. By minimizing early-stage engineering requirements, the platform can eliminate months of project preparation work and help accelerate overall project execution.
Targetting Commercially Bankable Hydrogen Projects
Dr. Hyunseok Jeong, Green H2 Business Team Leader at Samsung E&A, said the new solution reflects the company’s strategy of combining technical performance with commercial viability. According to Jeong, the expanded CompassH2 portfolio allows customers to select the most suitable electrolysis technology based on the unique technical and economic requirements of each project.
Partnership Extends Across Downstream Green Fuel Value Chain
For customers using hydrogen as a feedstock rather than an end product, Samsung E&A also offers engineering, procurement, and construction (EPC) capabilities across downstream green fuel applications, including green ammonia, e-methanol, and sustainable aviation fuel (SAF). The company stated that this integrated EPC capability under a single counterparty structure improves bankability while reducing execution risk for developers and financial institutions.
As per the press release, with the launch of CompassH2-A+, the Samsung E&A–Nel partnership now provides a complete electrolysis portfolio spanning atmospheric alkaline, pressurized alkaline, and PEM technologies, further strengthening its position in the rapidly growing global green hydrogen market.
