SIQENS GmbH has expanded its executive management team. Dr. Thomas Klaue, serving as a non-executive member on behalf of the founders on the SIQENS Board of Directors, has been assigned as Chief Operating Officer and will jointly manage the company with Volker Harbusch, one of the founders.

Thomas Klaue has been a member of the SIQENS Board since 2019. Serving in CEO and CFO positions for more than 15 years in the technology and life-science industry, mostly in publicly listed companies, he brings extensive experience in equity capital markets, repositioning, and internationalization of companies to SIQENS. In his new role as CEO, he will draw on this expertise to direct the company in its strategic and operational transition to a global provider of environmentally friendly fuel cells for critical infrastructures and for solutions in the hydrogen industry:

“I am looking forward to this new challenge. Our fuel cells will replace diesel generators in a carbon-neutral way. And our technology for hydrogen separation provides a solution for the ‘last mile’ in the hydrogen infrastructure to make the ‘green oil of the future’ available everywhere”.

Volker Harbusch, heading SIQENS GmbH since its founding in 2012, has led the development of the SIQENS Ecoport from conception to serial production and will focus on technology and innovation in his role as CTO.


SIQENS, founded 2012 in Munich, is a leading provider of methanol fuel cells and technology for electrochemical hydrogen separation (EHS). The Company’s methanol fuel cell product line (Ecoport) supplies clean energy in remote areas or backup power to critical applications.

Built on its patented high-temperature polymer electrolyte membrane (HT-PEM) technology portfolio for power generation, SIQENS offers solutions to separate and purify hydrogen at the point of use from several feed gases – as from hydrogen-blends in natural gas pipelines or reformate gases from methanol or biogas. The SIQENS technology portfolio addresses the challenge of last-mile hydrogen distribution: Driving the decarbonization of power generation, transportation, and industry by reducing the cost of hydrogen delivery.
