The ANIONE project is a research and innovation project (under the Fuel Cells and Hydrogen 2 Joint Undertaking) that will develop high-performance, cost-effective and durable anion exchange membrane (AEM) water electrolysis technology. The ANIONE technology combines the advantages of proton exchange membrane and liquid electrolyte alkaline technologies and aims to validate a 2 kW AEM electrolyser with a hydrogen production rate of approximately 0.4 Nm3/h. To achieve this, innovative reinforced anion exchange membranes will be developed in conjunction with non-critical raw material electrocatalysts with high surface areas and membrane-electrode assemblies. Cost-effective stack hardware materials and novel stack designs will contribute to decrease the capital costs of these systems.

Hydrogen for a green future

The ANIONE technology will allow for a scalable, efficient and low-cost production of “green” hydrogen from a variety of renewable energy sources. The wide-scale production of hydrogen will enable large-scale applications in grid balancing markets, in power-to-gas storage systems, and in the sustainable transport and mobility sector. With its developments, the ANIONE project aims to contribute to the roadmap addressing the achievement of a wide scale decentralised hydrogen production infrastructure with the long-term goal to reach net zero CO2 emissions in EU by 2050.
