Project description
A viable solution to gigawatt-scale deployment of water electrolysis technology
Water electrolysis is a key technology for producing green hydrogen, essential for reducing carbon emissions. However, current catalysts such as iridium are expensive and scarce, limiting the use of the technology. To overcome this, the ERC-funded ARIEL project plans to develop sustainable, cobalt-based anodes as an alternative. These anodes have already proven their effectiveness in the laboratory, showing high activity rates and stability in proton-exchange membrane water electrolysers. Building on this success, ARIEL will create scalable synthesis processes that retain catalytic activity and stability. Researchers will create larger electrodes, validate their effectiveness and conduct economic and environmental analyses to support the commercial viability of the technology.
Objective
ARIEL (scaling sustainable Anodes for efficIent water ElectroLysis) seeks to demonstrate and validate a scalable process for the synthesis, activation, and implementation of non-platinum-group catalysts for water electrolysis a bottleneck on the path to the projected gigawatt deployment of this technology that is needed to meet carbon emission targets. We have previously demonstrated, at the lab-scale, the feasibility and potential of cobalt-based anodes as alternative to iridium in proton-exchange membrane water electrolysers (PEMWE), achieving activity and stability at PEMWE-relevant current densities (Science 384, 1373, 2024). ARIEL aims to build on these results translating original, non-scalable synthesis and manufacturing protocols into scalable processes that retain catalytic activity and stability. The aim is to demonstrate a process compatible with kg-synthesis and activation, prototyping electrodes up to 400 cm2; and externally validating these, as a prelude to the potential commercial exploitation of this invention. ARIEL will further assess the sensitivity of the different parts of the process on reliability, and perform scale-informed technoeconomic and lifecycle analysis to evaluate different
exploitation schemes.
