Ohmium is a startup that operates in the green energy sector, specifically focusing on the production of green hydrogen. The company designs and commissions cost-effective and reliable green hydrogen electrolyzers, which are devices used to split water into hydrogen and oxygen using an electric current. This process is powered by renewable energy, making the hydrogen produced a sustainable resource.

Ohmium's primary product is the Lotus™ PEM Electrolyzer, a scalable and versatile solution that can be used in various industries, including power, transportation, and other industrial sectors. The electrolyzers are designed to be easily stacked, allowing for efficient scaling as a business's hydrogen needs evolve.
