Green Hydrogen Between Research and Industry
Klaus Ohlig of thyssenkrupp nucera at the JARA-ENERGY Talks
Green hydrogen is widely regarded as a key technology on the path toward climate neutrality and is the focus of intensive research and industrial development worldwide. Against this backdrop, the 14th JARA-ENERGY Talks took place on January 8, 2026. Around 50 guests attended the event at the SuperC building of RWTH Aachen University, where Klaus Ohlig, Chief Technology Officer of thyssenkrupp nucera, provided insights into current and future electrolysis technologies for hydrogen production.
Ohlig presented thyssenkrupp nucera as a global leader in electrolysis technologies and demonstrated how the company leverages its long-standing expertise in chemical and process engineering for large-scale industrial projects in the gigawatt range. A particular focus was placed on alkaline water electrolysis, whose modular and scalable design enables low hydrogen production costs and high operational reliability. In addition, he outlined investments in complementary technologies such as pressurized alkaline electrolysis and high-temperature electrolysis (SOEC), aimed at strengthening long-term competitiveness.
The presentation also addressed current market conditions and regulatory frameworks, highlighting that despite existing uncertainties, Europe currently remains the most attractive market. In conclusion, Ohlig emphasized that, despite a temporary market slowdown, significant growth in global green hydrogen capacities is expected by 2030.
The subsequent open discussion featured numerous questions from the audience, which were addressed in detail by the speaker.
