Procedure for storing hydrogen in liquid form
P202131178
Researchers from the Institute of Advanced Materials at the Universitat Jaume I in Castelló and the Universidad de Zaragoza have developed a procedure for storing liquid hydrogen using liquid organic hydrogen carriers (LOHC). The process comprises two consecutive catalytic dehydrogenation stages and a hydrogenation stage. The working temperatures of all the processes are below 160°C. In the present invention, heterogeneous catalysts are used to ensure the viability of storage, as well as reuse and recycling. The process uses hydrogen carriers that are abundant and widely used in industrial applications, as well as being non-toxic and with a high hydrogen storage capacity (6% by weight).
Technical advantages: - It is a reversible system for storing and transporting hydrogen in response to demand. - It allows hydrogen to be stored for long periods of time at low cost. - The system has a large capacity for hydrogen storage by weight (6%). - The hydrogen conversion and reconversion steps are carried out at maximum temperatures of 160°C. - The catalysts can be recycled and reused. - It is an energy system that allows for decarbonisation and has a zero carbon footprint. Sectors for commercial application: - The invention is applicable to companies engaged in the production and marketing of energy storage and transport solutions. - It is aimed at companies interested in hydrogen technologies and, in particular, the storage of hydrogen in liquid form using organic liquids as hydrogen carriers.
