At SoHHytec, we are developer and manufacturer of patented systems for the direct conversion of solar radiation and water into fuel (hydrogen, oxygen) and power (electricity, heat) for industrial, commercial, and farming sectors, based on patented solar ‘Artificial Tree’ (the Arb).
EPFL, Switzerland
Our journey in solar hydrogen production began with the successful demonstration ofa lab-scale prototype of our IPEC device, as documented in [Tembhurne et al.,Nature Energy 2019]. This device, renowned for its world’s highest output performance per area, achieved a solar-to-hydrogen efficiency of 17.12% at EPFL's laboratory.Building on this success, we embarked on our first product-scale pilot demonstration at EPFL, Switzerland. This pilot has been in continuous operation for over two years, achieving solar-to-hydrogen efficiency of 24.4% [Isaac Holmes, Tembhurne, et al., NatureEnergy 2022]. Recently, our efforts have moved beyond controlled environments, culminating in exhaustive testing under real-world conditions on the EPFL Lausanne campus. Our focus remains on refining and validating this pilot, gearing it for extended, automated testing.
Switzerland
Taking a significant leap, we are currently developing our first industrial pilot at a client's location in Switzerland. Our collaboration with the client, a stainless steel tube manufacturer consuming over 54 tonnes of hydrogen annually– aims to achieve independent green hydrogen production. The infrastructure will have an installed capacity of 100kWp with five Arbs.
