During OHPERA’s first year, the consortium showcased strides in scientific excellence, from efficient photoelectrodes for Hydrogen production to pioneering investigations of lead-free halide perovskite nanocrystals.
Progress in Scientific Objectives:
Efficient Photoelectrodes for H2 Production and Glycerol Oxidation
Novel lead-free halide perovskite nanocrystals developed by UJI show promising optoelectronic properties. Thin film deposition is underway, achieving photocurrents of 0.5 mA cm-2. Expectations are set high for reaching the targeted 15 mA cm-2 by the end of 2024. Electrodes for glycerol oxidation have been developed by BGU, showcasing selective glyceric acid production with 80% efficiency for Ni-Bi. The combination of photoactive films with catalytic layers is on the horizon, with stability evaluations approaching.
Investigation of Photoelectrochemical (PEC) Systems Based on lead-free perovskite nanocrystals (PNCs)
ICIQ has delved into the theoretical and experimental exploration of PEC systems. Their team worked on the mechanistic descriptions of bulk and surface processes, and they are preparing degradation pathways and reaction networks for the next 12-month period.
Lab-Scale Tandem PEC Cell
HZB, with inputs from UJI and BGU, has designed the integrated PEC cell. They are progressing with modelling for simultaneous glycerol oxidation and hydrogen production, with fabrication and testing set to commence by the end of 2024.
Progress in Technological Objectives:
LOM leads the project’s sustainability guidance and validation, integrating it from design to end-of-life considerations. A life cycle approach and Responsible Research and Innovation (RRI) initiatives have been implemented.
Progress in Innovation Objectives:
eCHEM‘s market analyses delve into hydrogen production and glycerol valorisation. Their preliminary assessments form the basis for a comprehensive exploitation roadmap, aligning business and technological readiness levels.
These are just the first steps towards our project goal. Stay tuned for more updates as we continue to innovate and drive sustainable change!
