Summary
The overall objective of the ANIONE project is to develop a high-performance, cost-effective and durable anion exchange membrane water electrolysis technology. The approach regards the use of an anion exchange membrane (AEM) and ionomer dispersion in the catalytic layers for hydroxide ion conduction in a system operating mainly with pure water. This system combines the advantages of both proton exchange membrane and liquid electrolyte alkaline technologies allowing the scalable production of low-cost hydrogen from renewable sources. The focus is on developing advanced short side chain Aquivion-based anion exchange polymer membranes comprising a perfluorinated backbone and pendant chains, covalently bonded to the perfluorinated backbone, with quaternary ammonium groups to achieve conductivity and stability comparable to their protonic analogous, and novel nanofibre reinforcements for mechanical stability and reduced gas crossover. Hydrocarbon AEM membranes consisting of either poly(arylene) or poly(olefin) backbone with quaternary ammonium hydroxide groups carried on tethers anchored on the polymeric backbone are developed in parallel. The project aims to validate a 2 kW AEM electrolyser with a hydrogen production rate of about 0.4 Nm3/h (TRL 4). The aim is to contribute to the road-map 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. To reach such objectives, innovative reinforced anion exchange membranes will be developed in conjunction with non-critical raw materials (CRMs) high surface area electro-catalysts and membrane-electrode assemblies. Cost-effective stack hardware materials and novel stack designs will contribute to decrease the capital costs of these systems. After appropriate screening of active materials, in terms of performance and stability, in single cells, these components will be validated in an AEM electrolysis stack operating with high differential pressure and assessed in terms of performance, load range and durability under steady-state and dynamic operating conditions. The proposed solutions can contribute significantly to reducing the electrolyser CAPEX and OPEX costs. The project will deliver a techno-economic analysis and an exploitation plan for successive developments with the aim to bring the innovations to market. The consortium comprises an electrolyser manufacturer, membrane, catalysts and MEAs suppliers.

H2020-EU.3.3.8.2. Increase the energy efficiency of production of hydrogen mainly from water electrolysis and renewable sources while reducing operating and capital costs, so that the combined system of the hydrogen production and the conversion using the fuel cell system can compete with the alternatives for electricity production available on the market
