About the project
AH2A will contribute to develop a technology for sustainable utilization of renewable energy resources in Norway - while preserving the Natural environment and ensuring security of H2 supply. Dry pressurized H2 will be produced from renewable energy sources for higher well to tank efficiency utilizing a proton conductor working at intermediate temperature. AH2A will further develop electrolyser cells based on the metal supported (MS) thin film of proton-conducting BaZr0.85Y0.15O3 electrolyte developed at SINTEF/UiO in the METALLICA project using pulsed laser deposition (PLD). AH2A will develop improved smooth intermediate conducting layers (SICL) and novel electrodes which is critical for the electrolyser assemblies working at 600°C to reach a total resistance less than 1 ohm.cm2 for the cell. In addition air electrode with good electrochemical properties under high water vapor composition compatible with fabrication routes based on wet chemical - and vacuum methods. In collaboration with the international partners, the scalability will be demonstrated through the realization of 6 x 6 cm2 cells with optimized components using a novel PLD at SINTEF. Testing of these cells will be done to prove the target and investigate for possible long-term degradation issues under operation. These robust electrolysis cells with an overall low resistance will, when fully optimized, enable efficient Production of H2 from water by renewable energy and waste heat from industry. This pioneering work will open new scientific and technological pathways for sound management of renewable sources and deployment of protonics technology within innovative SMEs.
The project is funded by Research Council of Norway under the ENERGIX programme.
The project lasts 3 years and is led by SINTEF in collaboration with UiO.
