Stammtisch - Artificial photosynthesis for Solar Hydrogen production and its industrialization

#hydrogen #solar #energy

Solar energy is intermittent by nature, and converting it into chemical energy via photo-electrochemical (PEC) processes is one viable route for renewable fuel processing and energy storage. However, practical viability requires such an approach to be efficient, robust, economically competitive and sustainable at the same time.

PEC devices operating with optical and current concentrations can satisfy all these aspects for deployable solar fuel generation. Furthermore, a close thermal and electronic integration of the photoactive and electrochemical component allows to achieve higher operating current densities while maintaining high efficiencies.

SoHHytec developed an artificial tree called ‘Arb’ deploying the integrated photo-electrochemical technology which will be presented. Arb is a plug and play solution for solar hydrogen (fuel) and power co-generation. SoHHytec is deploying Gardens and Forests of multiple of Arbs for catering to the needs of industrial, mobility, and energy storage sectors.

Participation to this event is free, open to all, IEEE members and non-members. No registration required.

Dr. Saurabh Tembhurne


Dr. Saurabh Tembhurne is the CEO and Founder of SoHHytec SA/LTD.

He did his Bachelor’s degree in electrical engineering with a master's in microelectronics from IIT Bombay, India. Later he moved to EPFL, Switzerland where he finished his Ph.D. in Energy particularly Solar-fuels. IIT Bombay was the breeding ground for the research-entrepreneur in Saurabh and then EPFL served as the realizing ground.

SoHHytec's core-technology is developed as part of Saurabh's Ph.D. work. Saurabh has published several high impact journal papers and is the inventor of SoHHytec's core patents. He has 10+ years of experience in the field of solar energy and solar fuels.

Apart from an expert technological background, he has gathered strong business and entrepreneurial acumen winning several highly competitive awards. Saurabh is leading the SoHHytec as the chief executive officer and is a leader and strategist for making sustainable solutions of future a reality of today.

SoHHytec is currently recognized among World's Best and leading innovative Hydrogen ventures.
