This will feed the platform for green value chains with H 2 as intermediate for products (e.g. via the syngas platform or the ammonia platform), for mobility and for heating. The key technology in this value chain is H 2 production via electrolysis. Hydrogen production via electrolysis is currently done only at MW scale. However, to match the demand for hydrogen of the Dutch industry and to play a significant role in buffering the future intermittent power supply, a significant scale up is required of the electrolyser capacity at least to the GW scale. Objective Develop a conceptual design and a transparent cost estimation methodology, fit for implementation in 5 industrial regions, for a 1-GW electrolyser plant that is ready for start-up in 2025 – 2030 and that delivers H 2 at an economically viable cost level (reduction of total annualized costs is essential). Approach The project consists of 3 parts. These 3 parts are developed in close contact in an iterative process. Part 1 delivers a design of electrolyser stacks and modules, a heat management model, a CAPEX learning curve, an electrolyser operating model. Part 2 delivers the context of 5 industrial regions in terms of regional demands, infrastructure and plot size, including system integration options and feasibility assessment. Part 3 delivers a conceptual design, including balance of plants and the expected economics for plant erection in 2025-2030. 5 industrial regions Results The 3 parts of the projects have been started. First results of part 1 will be delivered in Q4 2019. For part 2 regional consortia have been formed and studies on infrastructure have been selected. For part 3 a baseline concept has been defined. Next steps • Report on scale-up limitations. • A first assessment plot size of the facility. • Input of regions will be collected • For part 3 a subsidy request will be submitted in Q4 2019. This project is co-funded by TKI-E&I with the supplementary grant 'TKI- Toeslag' for Topconsortia for Knowledge and Innovation (TKI’s) of the Ministry of Economic Affairs and Climate Policy.
