Ohmium International has launched the third generation of its Lotus PEM electrolyser, achieving a footprint of just 29.7 m² per MW, including access and maintenance areas. The system integrates all balance of plant (BoP) components, from power electronics and water treatment to purification and cooling, enabling direct conversion of AC power and city water into pressurised, high-purity hydrogen.

The Lotus Mark 3’s hyper-modular design eliminates the need for cranes in most installations and uses a rack-in/rack-out system for easier maintenance. This reduces construction time, downtime, and overall project costs, making large-scale green hydrogen production more commercially attractive.

Ohmium has a pipeline of more than 2 GW across three continents and proven deployments in extreme conditions from –40°C to 55°C, positioning it as a leading player in global green hydrogen expansion.
