OHS helps industrial companies produce clean hydrogen right where they need it, delivering both environmental benefits and cost savings. Our electrolyser systems range from small-scale (2.4 kW) to industrial-scale (100 kW), producing between 0.044 kg and 2 kg of green hydrogen per hour. These systems work seamlessly with companies' existing solar panels, and generated waste heat during the electrolysis process can be easily integrated into building heating or manufacturing processes—making the most of energy that would otherwise be lost. This on-site approach offers companies multiple advantages. They significantly reduce their carbon footprint while improving operational efficiency and gaining better control over energy costs. Instead of relying on hydrogen deliveries—which can face delays and supply chain issues—companies become energy independent. The economics are compelling: producing hydrogen on-site is already more cost-effective than having it delivered.

Avantages pour l’environnement

• •Independent hydrogen supply: Our 2.4 kW H2-OnSite unit makes up to 1 kg H₂/day for labs, while our 100 kW system delivers up to 48 kg/day — enough for SME production — eliminating external gas deliveries and ensuring secure, on-site hydrogen generation
• •Scalable, future-proof design: The H2-OnSite system grows with your needs — start small, expand modularly, and stay ready for future business opportunities without replacing the core infrastructure
• •Carbon Reduction: Our green hydrogen emits ~3 kg CO₂/kg H₂ (due to PV) vs. 10 kg for fossil hydrogen, cutting emissions by ~75%
• •Réduction des émissions de carbone : Notre hydrogène vert émet ~3 kg de CO₂/kg de H₂ (grâce à l'énergie photovoltaïque) contre 10 kg pour l'hydrogène fossile, ce qui réduit les émissions de ~75 %.
• •En avance sur les objectifs réglementaires : Notre solution H2-OnSite est conforme à la norme RED II, ce qui signifie qu'elle répond déjà aux futurs quotas de carburants renouvelables de l'UE (42,5 % d'ici à 2030 et 60 % d'ici à 2035), permettant ainsi aux clients industriels de mener la transition énergétique en avance sur le calendrier.

Les avantages financiers

• •Hydrogen cost savings: H2-OnSite cuts hydrogen expenses by ~24%, reducing reliance on costly delivered hydrogen
• •Additional benefits: Waste heat recovery, CO₂ certificates, and low or negative electricity prices can further improve overall savings
