Ohmium Names Markus Tacke CEO to Drive Global Growth in Green Hydrogen Electrolyser Business

Ohmium, a hydrogen tech company based in the US with manufacturing roots in India, is bringing on Markus Tacke as its new CEO starting July 1, 2025. With a solid track record leading Siemens Wind Power and later Siemens Gamesa, Tacke’s no stranger to scaling up renewable energy ventures—and now, he’s taking the reins at a time when green hydrogen is really picking up steam.

A Big Step in the Growth of Green Hydrogen

As the world shifts gears toward cleaner energy, the demand for low-emission hydrogen is heating up, especially across the US and Europe. Governments are rolling out policies to back up this transition, and Ohmium is ready to take advantage. The company is expanding its global footprint with its PEM electrolyser technology, aiming to make hydrogen production more cost-effective and scalable. That’s where Tacke’s leadership comes into play—his focus will be on cutting costs, boosting efficiency, and keeping Ohmium at the forefront of the green hydrogen movement.

India at the Heart of Hydrogen Infrastructure

Ohmium’s choice to manufacture in India isn’t just about cost—it’s a nod to the country’s rising influence in the global clean tech scene. As more industries lean into industrial decarbonization, Ohmium’s setup is in a sweet spot to supply the growing need for next-gen energy solutions. With Tacke stepping in, the company’s got its eyes not just on steady growth, but on becoming a real leader in the race to build out global hydrogen infrastructure.
