Hydrogenious’ LOHC technology is based on years of thorough research in the area of Liquid Organic Hydrogen Carriers (LOHC). As a university spin-off and a company of scientists, engineers and entrepreneurs, Hydrogenious Technologies focuses on the commercialization of the LOHC technology and optimizes catalysts, reactor technology and system integration.
In addition, a large group of scientists at the Friedrich-Alexander-University Erlangen-Nuremberg (FAU) including the co-founding professors Wasserscheid, Arlt and Schlücker continue to push the limits of the LOHC technology. If you are interested in the capabilities, potential and origin of our LOHC technology you can find more insights in the publications featured here.
