Publieke samenvatting / Public summary

Aanleiding
Fighting climate change is central to the mission of Air Liquide and its commitment to develop a wide range of solutions. In the past 50 years, Air Liquide has developed unique expertise enabling it to master the entire hydrogen supply chain, from production, operation and storage to distribution and the development of applications for end users, thus contributing to the widespread use of hydrogen as a clean energy source. To kickstart a new hydrogen-driven economy, it is imperative that large scale electrolyzers are demonstrated and brought to maturity. The project fosters the implementation of the objectives of the Dutch Climate Agreement. To reach the CO2 emission reduction goals for 2030, the Dutch government envisages a major role for hydrogen in a decarbonised energy system. This requires large investments in the development of renewable hydrogen production. This project will significantly contribute to reaching the target set under the Climate Agreement which is to have an electrolyzer capacity of 500 MW in the Netherlands by 2025 and 3-4 GW by 2030.

Doelstelling
In this TSE Energiestudies project the technical and economical feasibility of a large water electrolyzer will be studied to substantiate the Final Investment Decision for a demonstration project. Air Liquide intends to develop the ELYgator, a highly integrated large-scale 200 MW water electrolyzer that will be entirely sourced from renewable power sources and will enable avoidance of 4 Mtons of CO2 over the first 10 years of the plant's operation, compared with conventional sources of hydrogen produced from natural gas. These projects correspond to program line 3: MMIP 8. This program line is focused on the development of innovations for climate neutral production processes in 2050, optimally electrified and fully integrated in the renewable energy system. There is a strong contribution to the first subprogram 'Production of hydrogen, molecules, and innovative renewable fuels' as this project will demonstrate a First-of-its-Kind large electrolyzer. There is a contribution to the second subprogram: the electrolyzer helps to balance the electrical grid, a feature that is becoming highly sought after due to the increasing amount of renewable energy production on the Dutch grid.

Korte omschrijving
The activities in this project will include the determination of a competitive plant design for the site that meets safety and design requirements, the selection of a technology provider for the Front-End Engineering Design study, and an estimation of the required investment for the project. Furthermore, the demonstration project planning and organisation will be thought out, the repeat potential of the concept in the Dutch market will be analyzed, and the project's fit in the Dutch power grid is confirmed. The project will be executed by Air Liquide Benelux Industries, supported by Air Liquide Engineering & Construction and external advisors where applicable.

Resultaat
This TSE project will provide the required documentation and substantiation for the Final Investment Decision for the ELYgator project by Air Liquide. The ELYgator project will see the first demonstration of a very large scale electrolyzer, significantly pushing forward the state of the art electrolyzer technology. Air Liquide brings its experience and know-how to demonstrate the 10-fold upscaling compared to currently available electrolyzer capacities, including full traceability of the hydrogen carbon footprint along the full supply chain, from renewable power production to the end-customers. The ELYgator project incorporates various innovative elements into an integrated design, such as a hybrid set-up (both PEM and Alkaline) allowing several optimisations, inclusion of an electric boiler to maximize the full load hours of the electrolyzer, valorisation of the co-produced oxygen (industrial symbiosis), providing highly responsive virtual storage capacity to balance the grid and lower emissions, combining both mobility and industrial renewable hydrogen usages and the use of Air Liquide's extensive European pipeline network both as a supply mode and as buffer.
