Advanced GW Water Electrolysis

Publieke samenvatting / Public summary

The ISPT Hydrohub Innovation Program carries out innovation to realize affordable green hydrogen at scale. The GW water electrolysis project is the landmark project of this program that explores scaling-up. It delivers an optimised design and five regional blueprints, taking into account the need for dynamic operation to support balancing and grid stability due to intermittency in renewable electricity supply. The Dutch ambition relates to a global 100 GW water electrolysis in 2030, which requires an approximate 50-100 billion € scale investment. This provides great business opportunities for the Dutch high-tech “maakindustrie” to step into the fast-developing water electrolysis industry. The GW project builds key assets to kick-start this development, addressing e.g. modularization and standardization through its (systems) engineering approach. The GW project and its industrial consortium are a timely signpost that guides the Dutch high-tech industry towards this global opportunity.

The target is to obtain the key insights to achieve a cost reduction for CAPEX from current 1000 to 350 €/kW total installed costs. This is achieved by developing and applying a science-based design approach and executing design cycles delivering five GW plant blueprints for the industrial clusters. This provides the perspective to deliver economically viable green hydrogen production on a GW scale by 2030.

Korte omschrijving
The GW-project consists of three coherent parts that together deliver a complete and optimized design tuned to the local requirements in the five industry clusters. Part one brings a science basis and tools to support design optimisation. Part two is investigating the regional conditions. Part three, this project, focuses on design and engineering across the full plant. Activities are as follows: 1. integrating GW design in five industry clusters; 2. preparing optimised and advanced design: ? exploring systems engineering and normalisation and standardisation; ? investigating power electronics and electricity utilisation; ? optimising cost-effective design electrolyser including flexible operation; 3. developing cost estimates for design of viable GW facilities in five regions towards 2030 4. conducting financial-economic feasibility assessment; 5. continuing dialogue with high-tech industries and suppliers for electrolyser and rectifiers.

The project will provide the numbers and economics for potential deployment of GW water electrolysis facilities in five industrial clusters in the Netherlands. Description of results of this project: 1. blueprint designs with system integration of GW facility in five regions; 2. design package for optimized advanced GW water electrolysis and Capex cost estimate; 3. methodology, tool and graph for cost estimating development; 4. report with financial-economic feasibility assessment; 5. roadmap with suppliers and high-tech industry.
