Antares Electrolysis
Modular AEM electrolyzers for cost-effective green hydrogen and e-fuel production
Antares Electrolysis designs and builds next-generation AEM electrolyzer stacks and components for the sustainable, decentralized production of green hydrogen and electro-derived chemicals.
Green Hydrogen Production: The Emissions Challenge in Hard-to-Abate Sectors
8–10kg
of CO₂/kg of hydrogen created through the most common production method, steam methane reforming (SMR)
Hydrogen is essential for decarbonizing heavy industry and transport, but 95% of it is still produced from fossil fuels, emitting over 800 million tons (Mt) of CO₂ annually. Existing clean technologies are either too costly, inefficient, or reliant on critical raw materials. This blocks the scale-up of green hydrogen, a key pillar for achieving global net-zero targets.
Revolutionizing Green Hydrogen Production with AEM Electrolyzer Stacks
Antares develops high-efficiency, low-CAPEX AEM electrolyzer stacks that enable sustainable production of green hydrogen and e-fuels. Our technology combines the performance of PEM with the affordability of alkaline systems, unlocking clean molecule generation without critical raw materials and making decentralized, zero-emission production viable at scale.
Cutting Industrial Emissions with Clean Hydrogen Production
42
tons of CO₂ equivalent avoided per year, for each 100 kW of Antares Stack on the market, which can produce 4,200 kg of green hydrogen.
Antares targets the hardest-to-abate 6% of global emissions—those from sectors beyond the reach of electrification. Our efficient, low-cost electrolyzers enable delocalized green hydrogen and e-fuels production, supporting a more resilient, decentralized, and secure energy policy while reducing dependency on fossil imports and lowering operational costs.
Antares provides claner hydrogen solutions for:
Green hydrogen production for industrial useE-fuels synthesis for shipping and aviationFertilizer and ammonia productionRefineries and chemical industry decarbonizationRemote/off-grid energy systemsThe benefits of Antares AEM stacks
Antares provides high-efficiency, low-CAPEX AEM stacks—the core "engine" of the electrolyzer—enabling manufacturers to deliver cheaper green hydrogen to end-users. By supplying only the stack, we lower the barrier for new players to enter the electrolyzer market, removing the need to develop deep tech internally and accelerating the growth of the green hydrogen economy.
