Core offering

Exion Hydrogen designs, develops, and manufactures containerized water electrolyzers for industrial on-site hydrogen production. Its product portfolio spans two proprietary platforms — the HyGGe™ 100A pressurized alkaline electrolyzer (100 Nm³/h at 30 barg) and the HyGGe™ 500P pressurized PEM electrolyzer (500 Nm³/h at 30 barg) — along with proprietary HIFI™ flow-optimization technology, gas purification modules, control systems, maintenance services, and spare parts packages.

Product overview

Exion Hydrogen offers two main water electrolyzer product lines: the HyGGe™ 100A (pressurized alkaline, 100 Nm³/h) and the HyGGe™ 500P (pressurized PEM, 500 Nm³/h). Both systems are containerized for easy transport and installation, producing high-purity hydrogen for industrial, energy, and mobility applications. The products share a common philosophy of 'no compromises' on safety, reliability, and durability, but differ in electrochemistry—alkaline uses KOH electrolyte while PEM uses proton exchange membrane. The HIFI™ technology is a proprietary feature specific to the PEM platform that optimizes internal flow dynamics for improved performance and longevity.

Direct peers

• Nel ASA: Norwegian manufacturer of both alkaline and PEM water electrolyzers at industrial scale, with multi-GW order book. Closely comparable dual-chemistry platform and direct overlap with Exion's industrial customer segments.
• Thyssenkrupp nucera: German supplier of alkaline water electrolyzers (and selective PEM) for industrial-scale green hydrogen. Closely aligned on alkaline technology focus, European manufacturing, and large-industrial customer segments.
• John Cockerill: Belgian engineering group offering alkaline electrolyzer stacks and integrated hydrogen production systems. Comparable alkaline technology offering and European industrial customer overlap, including steel and chemicals.
• ITM Power: UK-based PEM electrolyzer manufacturer targeting industrial and mobility hydrogen applications. Directly comparable in product category, target customer base, and European regulatory positioning.
• Plug Power: US-headquartered PEM electrolyzer and fuel cell company serving industrial gas and mobility customers. Comparable product offering (PEM electrolyzers) and overlapping customer base in industrial hydrogen.
• McPhy Energy: French alkaline and PEM electrolyzer manufacturer serving industrial, energy, and mobility markets. Comparable product portfolio, similar European industrial-decarbonization customer base, and mid-cap competitive positioning.

Emerging players

• Sunfire: German electrolyzer company specializing in high-temperature SOEC and PEM technologies for industrial-scale green hydrogen. Comparable European focus and industrial customer base, but differentiated by SOEC technology.
• Enapter: German-Italian PEM electrolyzer manufacturer focused on smaller-scale, modular AEM/PEM systems. Comparable product category and European manufacturing, but targets smaller-scale and distributed applications versus Exion's large-industrial focus.

Broad incumbents

• Siemens Energy: Diversified global energy technology incumbent with a PEM electrolyzer offering (Silyzer). Competes in the same industrial customer segments but as part of a much larger power-generation portfolio.
• Cummins (Accelera): US-based power technology incumbent with a PEM electrolyzer business (Accelera). Overlaps with Exion on PEM hydrogen production but operates as part of a much broader industrial portfolio.
