Supreme HydroGen (SHG)

What Supreme HydroGen (SHG) does

Supreme HydroGen (SHG), legally organized as Swedish Hydrogen Holding AB, is a Stockholm-based knowledge and engineering company founded in 2018 that develops, delivers, and commercially manages circular, green, and emission-free hydrogen energy solutions. The company serves three primary verticals: transport and marine (zero-emission mobility for heavy vehicles, ferries, and vessels), real estate and property (backup power, heating, and off-grid energy for commercial and residential buildings), and energy storage and grid (long-duration storage and grid stabilization). SHG positions itself as an independent integrator with access to an international technology supplier network rather than as a tied manufacturer, and explicitly anchors its identity in a "water to water" circular energy philosophy with water vapor as the sole byproduct.

SHG's technical stack centers on PEM (Proton Exchange Membrane) electrolysis and fuel cell technology, supplemented by metal hydride storage and pressure vessel storage at 200-700 bar. Production economics are quoted at approximately 50 kWh per kg of H₂ produced, with fuel cell lifespan of up to 90,000 hours and 120 MJ/kg energy density (approximately 3x diesel, 6x methanol). The company partners with Lavoit Technologies for AI-driven electrolyser optimization that improves efficiency, stability, and renewable electricity utilization.

Revenue is generated through hydrogen production and sales, system design and implementation, consulting assignments, and ongoing operation and maintenance. The Ljusterö Hydrogen Factory in the Stockholm archipelago was the flagship project (190 kg/day, 0.45 MW, projected 16 MSEK/year gross at full operation against 40-60 MSEK investment with a 5.5-8 year payback), but was handed over to a new investor in 2026, suggesting a strategic pivot toward engineering services and technology partnerships. Named commercial engagements are limited to Strömberg Energi AB (Ljusterö co-developer), Green City Ferries (Beluga 24 hydrogen passenger vessel), and Fischer Edelstahlrohre GmbH (Scandinavian consulting). With approximately 5 employees and no disclosed VC or PE funding, SHG operates as a lean integrator reliant on grant funding, technology partnerships, and project development fees.

Core offering

Supreme HydroGen is a Swedish knowledge and engineering company that designs, delivers, and commercially manages green hydrogen energy solutions for transport, real estate, and energy storage applications. The company provides end-to-end services spanning energy needs analysis, custom system design, project implementation, and ongoing operation and maintenance. Its offering is built around PEM electrolysis, PEM fuel cells, metal hydride storage, pressure vessel storage, and AI-driven electrolyser optimization, anchored by the flagship Ljusterö Hydrogen Factory project in the Stockholm archipelago.

Product overview

Supreme HydroGen is a Swedish knowledge and engineering company that develops, delivers, and commercially manages circular, green, and emission-free energy solutions. The company offers a portfolio of hydrogen solutions organized into three main service areas: Real Estate & Property Hydrogen Solutions (providing off-grid power, backup energy, and sustainable heating for buildings), Transport & Marine Hydrogen Solutions (powering vehicles and vessels with zero-emission hydrogen fuel cells), and Energy Storage & Grid Solutions (enabling large-scale energy storage and grid balancing). The flagship project is the Ljusterö Hydrogen Factory in Stockholm archipelago. All solutions utilize PEM (Proton Exchange Membrane) technology with electrolysis for production and fuel cells for power generation, supporting the company's 'from water to water' circular economy philosophy.
