Addressing the current energy, environmental and climate crisis with the production of green hydrogen is the main objective of the European project OHPERA (Optimised halide perovskite nanocrystalline based electrolyser for clean, robust, efficient and decentralised H2 production), which is coordinated by the Institute of Advanced Materials (INAM) of the Universitat Jaume I and brings together partners from Spain, Germany, Hungary and Israel in a consortium.

Through the development of an optimised electrolyser based on lead-free perovskite nanocrystals, the research team aims to obtain green hydrogen and high added-value chemicals from industrial waste (such as glycerol), using sunlight as the only energy source and thus demonstrating the feasibility of producing chemicals with economic benefits from industrial waste and using a renewable energy source.

The consortium is led at the Universitat Jaume I by researchers Sixto Giménez, who is also the coordinator of the European project, and Iván Mora Seró, both from the Institute of Advanced Materials, a centre specialising in the development of photoelectrodes based on PNC (lead-free perovskite nanocrystals), and will involve the participation of around fifteen researchers from the UJI.

Some of the partners are the Ben-Gurion University of the Negev (BGU) in Israel, expert in the manufacture of passivation and electrocatalytic layers that will provide the device with greater stability and efficiency, and the Institute of Chemical Research of Catalonia (ICIQ), which will contribute its experience in theoretical modelling for the optimisation of electrocatalysts and photoelectrodes.

The prototype device will be designed and commissioned by the German Institute for Solar Fuels of the Helmholtz Centre Berlin for Materials and Energy (HZB), with the support of the Hungarian company eChemicles, pioneer in developing innovative sustainable electrolysers, which will provide the industrial experience to address scale-up issues and design a realistic roadmap for its future commercial exploitation.

All the scientific developments will be performed under the guidance of Eco-design recommendations and the evaluation of the environmental, economic and social impacts through the Life Cycle Assessment methodology, provided by the Spanish SME Lomartov (LOM), thanks to its multidisciplinary expertise bridging scientific and market knowledge.

OHPERA is funded by the European Commission's Horizon Europe Research and Innovation programme, with a total budget of approximately three million two hundred thousand euros (€ 3,2M), under the schemes of the European Innovation Council (EIC) Pathfinder calls, which support research and development of emerging breakthrough technologies. The three-and-a-half-year project was launched last October with a meeting of the partners in Barcelona during the Materials for Sustainable Development Conference (MAT-SUS).
