Periodic Reporting for period 1 - OHPERA (Optimised Halide Perovskite nanocrystalline based Electrolyser for clean, robust, efficient and decentralised pRoduction of H2)
Reporting period: 2022-10-01 to 2023-09-30
OPHERA will integrate highly efficient and stable photoelectrodes based on halide lead-free perovskite nanocrystals (PNCs) and tailored catalytic/passivation layers, avoiding the use of critical raw materials (CRM), in a proof-of-concept eco-design PEC device.
Theoretical modelling both at an atomistic and device scales will assist the materials development and mechanistic understanding of the processes, and all materials and components will be integrated in a proof-of-concept device, targeting standalone operation at 10 mA·cm-2 for 100 hours, 90% Faradaic efficiency to H2, and including a clearly defined roadmap for upscaling and exploitation.
OPHERA will offer a dual process to produce green H2 concomitant to the treatment of industrial waste generating added-value chemicals with high economic and industrial interest, thus offering a competitive levelized cost of green H2.
