en.Wedoany.com Reported - Samsung E&A of Seoul, South Korea, in partnership with Nel Hydrogen ASA of Oslo, Norway, launched the CompassH2-A+, a 100 MW pressurized alkaline electrolysis solution, at the World Hydrogen Summit in Rotterdam. This is the third product in the CompassH2 series, which now covers atmospheric alkaline, pressurized alkaline, and proton exchange membrane (PEM) electrolysis technologies.
CompassH2-A+ is based on Nel's pressurized alkaline electrolyzers, utilizing a containerized 25 MW stack module design. Its compact design reduces the required plant footprint by 50% compared to similar market solutions, with hydrogen produced at a pressure of 15 barg, significantly lowering the cost and complexity of downstream compression equipment.
In a standard 100 MW configuration, CompassH2-A+ can produce approximately 40 tonnes of hydrogen per day with a purity of 99.999 mole percent, a stack efficiency of 48.8 kWh/kg, and a core footprint of just 7,500 square meters. The CompassH2 series also includes two existing products: CompassH2-A, which employs atmospheric alkaline technology with advantages in high efficiency and proven large-scale deployment; and CompassH2-P, which uses PEM technology and excels at handling load fluctuations from renewable energy sources; both are already available for supply. The newly launched CompassH2-A+ features a compact footprint and increased output at 15 barg as its key advantages.
Samsung E&A provides a wrap-around guarantee for the entire integrated system, covering the electrolysis stacks, balance of plant, and utilities, delivered under a single performance commitment and a single counterparty. This structure directly addresses the fragmented guarantee arrangements that have traditionally complicated project financing. A long-term service agreement extends the partnership across the plant's full lifecycle, including operational support, planned stack replacements, and real-time performance monitoring. As a pre-engineered solution, CompassH2-A+ also significantly shortens the timeline before the final investment decision, eliminating early-stage engineering work that often delays project progress.
Dr. Hyunseok Jeong, Head of the Green Hydrogen Business Team at Samsung E&A, stated that the launch of CompassH2-A+ reflects the team's commitment to delivering technologically excellent and commercially bankable solutions, and that expanding the CompassH2 portfolio provides customers with the flexibility to select the technology best suited to their project's unique needs.
For customers using hydrogen as a feedstock rather than an end product, Samsung E&A's capabilities cover the entire downstream value chain, including green ammonia, e-methanol, and sustainable aviation fuel, providing end-to-end coverage under a single EPC counterparty, transforming the risk profile for lenders and developers.
With CompassH2-A+, the collaboration between Nel and Samsung E&A now offers a complete electrolysis product portfolio covering atmospheric alkaline, pressurized alkaline, and PEM technologies, capable of tailoring solutions to the specific needs of each project. The launch of CompassH2-A+ follows the introduction of CompassH2-P in November 2025, marking a significant milestone in the long-term strategic partnership between Nel and Samsung E&A. The two companies stated they will continue to collaborate on technology portfolio expansion and competitive positioning to serve the rapidly growing global green hydrogen market.
