About SoHHytec

SoHHytec SA/Ltd is a Swiss company based in Lausanne that develops and manufactures patented systems for the direct conversion of solar radiation and water into fuel (hydrogen and oxygen) as well as energy (electricity and heat). The core product Arb – an all-in-one system – is based on the patented integrated photoelectrochemical unit (IPEC), which operates with concentrated solar radiation and splits water. The systems are fully automated, scalable and require a minimal footprint. The company offers needs analysis, system design (Gardens/Forests of Arbs), turnkey projects, and operation and maintenance over the lifetime, also as Hydrogen and Power as a Service. Customer industries include energy, power grids, industry (including fertilizers and chemicals), transport, commercial applications, as well as space and micro-grid applications. SoHHytec emerged from more than 10 years of research and development at the Laboratory of Renewable Energy Science and Engineering at EPFL and has its headquarters in the EPFL Innovation Park (Building C) in Lausanne.
