The European PeCATHS project will be developed through a multidisciplinary scientific consortium in chemistry, physics, engineering and photochemistry, led by the Institute for Advanced Materials of the Universitat Jaume I (INAM-UJI) in Castelló. Its aim is to develop a photoelectrochemical energy conversion system (which converts sunlight directly into chemical energy, without first converting it into electricity) that contributes to the creation of new energy networks, while providing sustainable and viable solutions for energy storage, transport and distribution.

In addition to the INAM-UJI, the scientific consortium includes the universities of Zurich (Switzerland) and Trinity College Dublin (Ireland), the research centres of the Catalan Institute of Nanoscience and Nanotechnology (Barcelona) and CIC energiGUNE (Vitoria) and the companies Comet Global Innovation and European Innovation Marketplace.

The European Green Pact Action Plan, adopted by the European Commission in 2020, aims to make the energy system more efficient and ready to increase the share of renewable energy sources. The new energy networks must incorporate more innovative digital solutions and a much smarter and more interactive network than the current one, resulting in significant energy savings that will benefit consumers.

The Castelló team, made up of researchers from the Hybrid Catalytic Materials, Electrocatalysis and Energy, and Research and Sustainable Development groups, is coordinated by José Mata, a professor in the Department of Inorganic Chemistry, and Francisco Fabregat, a professor in the Department of Applied Physics.

The current technology for obtaining green hydrogen is based on the splitting of water by electrolysis using green energy sources or photoelectrocatalysis. The cost of producing green hydrogen by water electrolysis is currently high compared to traditional methods, mainly due to the high price of electricity and catalysts. The PeCATHS project is working on a process to produce liquid hydrogen from biomass using solar energy.

The objective of the project is to combine the oxidation of biomass derivatives for the synthesis of value-added chemicals with the co-hydrogenation of liquid organic hydrogen carriers (LOHC) in a sustainable process for long-term energy storage. This approach allows the direct transfer of hydrogen from biomass to LOHCs without producing hydrogen gas and generates high-value chemicals.

The main advantage of LOHC technology is that it allows hydrogen to be stored in liquid form and to use existing infrastructure for its transport and distribution. The European project implements a cost-effective strategy that uses biomass as a hydrogen source and solar energy as a renewable energy source and directly integrates hydrogen into LOHC by avoiding gas compression and storage, thereby reducing costs and improving its competitiveness compared to other conventional storage methods.

PeCATHS aims to revolutionise renewable hydrogen energy storage through a novel technology that reduces the cost of green hydrogen production. This technology has the potential to accelerate the energy transition well before 2050 by keeping energy prices low, a crucial factor for a rapid decarbonisation of our society.
