Project description
Solid oxide electrolysis concept for hydrogen production
Green hydrogen stands as a cornerstone for a decarbonised economy, with solid oxide electrolysis (SOEL) emerging as an efficient method for its production. SOEL boasts electrical efficiencies nearing 100 %, using non-noble materials, and offers operational flexibility. However, to achieve commercial viability, challenges such as enhancing lifetime, mitigating degradation, addressing ceramic brittleness, and reducing scaling costs must be tackled. In this context, the EU-funded NOAH2 project will develop a cost-effective, durable, and flexible hydrogen production stack concept. It aims to improve the performance of solid oxide cells and stacks beyond the state-of-the-art while minimising the use of critical raw materials. The NOAH2 stack architecture will adopt a metal-based monolithic concept with infiltrated electrodes.
Objective
Hydrogen is a key energy vector in a future decarbonised economy. Large-scale application in numerous sectors, such as transport, iron & steel plants, and the chemical industry, requires efficient and sustainable production routes of green hydrogen. Electrolysis of water/steam using electricity from renewable sources like wind and solar is the solution. High temperature or solid oxide electrolysis (SOEL) has significantly attractive features, which allow for lower CAPEX and OPEX, thus facilitating commercial breakthrough: High electrical efficiencies approaching 100%, cost competitive, non-noble materials, and operational flexibility. SOEL challenges that need to be solved are increase of lifetime and reduction of degradation for realistic applications, the ceramic brittleness of most mature SOEL configurations, which challenge rapid operational strategies when integrated with renewable energy sources, and scaling costs for the required Mega to Gigawatt volumes.
NOAH2 aims at overcoming these challenges. The overall goal of the NOAH2 project is to provide a robust, cost-competitive, flexible, and durable stack concept for hydrogen production at intermediate temperatures through innovative electrode, cell, and stack designs. NOAH2 will boost the electrolysis performance of solid oxide cells & stacks significantly beyond State-of-the-Art (SoA) through a combination of optimised structures and highly active materials, with a focus on reducing critical raw materials (CRM) and manufacturability using well-established large scale routes for solid oxide technology. The NOAH2 stack architecture relies on a metal based monolithic concept with infiltrated electrodes.
NOAH2 will outline a path towards commercialisation, provide a sustainability classification with emphasis on substituting CRM, provide an assessment of commercialization potential compared to SoA SOEL, PEM, and Alkaline electrolysers, and identify potential industrial players for high-volume manufacture.
