Djewels

Djewels will demonstrate the operational readiness of a 20 MW high-pressure alkaline electrolyser with a compact footprint for producing green hydrogen and chemicals under real industrial and commercial conditions. The project will advance the technology from TRL 7 to TRL 8 and establish the foundation for scaling up to 100 MW on the same site. Djewels will drive the development of next-generation pressurised alkaline electrolysers by introducing cost-efficient, high-performance electrodes for medium current densities, preparing for serial stack manufacturing, and scaling balance-of-plant components. Economies of scale in electrolysis stacks and gas/liquid separators, combined with flexible operation through advanced electricity procurement and arbitrage strategies, will ensure low-cost hydrogen for end-users during three years of operation. Located in the Delfzijl industrial park, where Nobian already produces hydrogen via chlor-alkali processes and operates a CHP unit firing H2 for steam production, Djewels benefits from direct grid access and low distribution charges. The presence of other hydrogen industry clients and dense gas networks connecting to major chemical clusters in the Netherlands and Germany creates ideal conditions for scaling green hydrogen production. Djewels will serve as a stepping stone toward a hydrogen valley, supporting FCH2-JU ambitions and the regional roadmap within the Northern Netherlands industrial cluster and beyond.
