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

Hydrogen production is having a serious moment right now, and US-based company Ohmium is wasting no time making a bold move to ride the wave. On July 1, 2025, they're bringing industry veteran Markus Tacke on board as their new CEO. With deep roots in renewable energy, Tacke’s arrival signals a big step forward for Ohmium as it gears up to scale its PEM electrolyser tech in a rapidly evolving green hydrogen market.

A Global Vision, Led by Experience

Tacke is no rookie when it comes to major energy transitions. He previously led Siemens Wind Power through its high-profile merger with Gamesa, creating the global giant Siemens Gamesa back in 2017. That company eventually rolled into Siemens Energy AG, underlining his knack for guiding change and scaling innovation across borders.

He’s known for streamlining operations, cutting costs, and building global teams—skills that are going to be key as Ohmium looks to stand toe-to-toe with the top players in the PEM electrolyser space. With the industry heading into its next phase of competition and growth, Tacke brings the leadership chops to help Ohmium scale smarter and faster.

Why PEM Electrolysers Matter

PEM—short for Proton Exchange Membrane electrolyser—technology is what Ohmium has been betting on, and for good reason. These compact, fast-reacting systems are perfect for teaming up with renewable sources like wind and solar. When renewable power is available, these devices use electricity to split water into hydrogen and oxygen—providing a pathway to clean, green hydrogen.

What really sets PEM apart is its agility—it handles fluctuations in renewable energy better than most competitors. And with Ohmium’s vertically integrated manufacturing in India, they’ve got the foundation needed to deliver these systems affordably and at scale. Now it’s all about tightening efficiency and hitting execution milestones.

India: Ohmium’s Secret Weapon

Choosing to manufacture in India is more than just about cutting costs—it's a savvy strategic move. India is fast becoming a hub for clean tech production, thanks to its massive population, growing demand for green energy, and supportive government policies.

With skilled engineers, competitive operating costs, and experience producing key components like solar PV and wind turbine systems, India is well-positioned to become a major force in the hydrogen space too—and Ohmium is ahead of the curve here.

This Move Sends a Clear Message

Bringing Tacke on isn’t just a personnel shift—it’s a strong signal that Ohmium is done playing small. The global hydrogen economy is moving from idea to action, and it’s increasingly being shaped by big players with big ambitions. With major government support from policies like the US Inflation Reduction Act and the EU’s long-term hydrogen infrastructure goals, now’s the time to scale fast—or get left behind.

Tacke’s reputation and resume bring credibility that matters—whether you’re talking investments, commercial partners, or large-scale projects. His leadership could help unlock new doors and drive Ohmium into new markets with more confidence and momentum.

The Pressure's On for Other Electrolyser Players

Let’s face it—the PEM electrolyser space just got more competitive. With hydrogen demand surging around the world, companies that can scale fast and deliver reliably will grab the biggest slice of the pie.

From fueling clean steel and fertilizer production to reshaping entire supply chains, industrial decarbonization is accelerating. Ohmium, now backed by a CEO who knows how to manage multinational operations and complex rollouts, seems ready to not only take part—but take the lead.

What’s Next? A Perfect Storm of Opportunity

This CEO announcement isn’t just a news blip—it’s a turning point. It reflects a rare alignment of experienced leadership, mature technology, and rising global demand for green hydrogen.

Ohmium’s plans to ramp up deployment of its latest PEM electrolysers feel more grounded—and more ambitious—than ever. As the energy transition heats up, keep an eye on this company. They’re not just aiming to grow; they’re stepping up to lead.
