In the energy system of the future, renewable electricity plays a key role and the key technology in this value chain is green hydrogen production via electrolysis. The transition to renewable energy feeds the platform for green value chains with H2 as intermediate for products (e.g. via the syngas platform or the ammonia platform), for mobility and for heating.
Hydrogen production via electrolysis is currently done only at 1-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 1-GW scale.
In the quest for eliminating CO2 emissions, while maintaining and enhancing energy consumption and industrial activity, more and more hydrogen is seen as part of the solution, both as an energy carrier, as well as feedstock for chemical production.
Water electrolysis based on green electricity to produce green hydrogen qualifies perfectly for this purpose. However the technique needs further development in order to scale it up into an economically and operationally viable large scale (GW) solution in industrial clusters. This project serves this aim and consists of three parts:
1) Scientific: Which of the existing electrolysis technologies has the best potential? Such as, among others, costs, flexibility, heat management and pressure expectations, to be the core of the concept. What will be the effect of mass production on costs and performance? Which is the resulting operational model of the technology in order to serve the needs of real industrial cluster demands (E-input, H2 output)?
2) Business: What is the real context of the five industrial clusters (located in Rotterdam, Amsterdam-Ijmuiden, Geleen, Terneuzen-Sluiskil, and Delfzijl-Eemshaven)? What are real capacity-, volume-, and economic demands for hydrogen, oxygen, and heat? What are infrastructural possibilities and constraints?
3) Engineering: How can this result in a conceptual design that gives a full overview of what is necessary? Think of inside and outside battery limit (the electrolysis installation) to deliver industrial cluster demands at given E- supply patterns (eg wind-patterns). In addition, it is evident to conclude on the economics (eg CAPEX, OPEX, hydrogen costs).
This project will be carried out till late 2021, and have an iterative character since several loops will be necessary to come to an optimum result. This optimum should reflect economically viable hydrogen costs in the expected near future (2025 and onwards).
These hydrogen costs will be the result of the final conceptual design, but will also be influenced by potential upsides: eg Oxygen and Heat credits. The benchmark hydrogen reference, will consist of present grey hydrogen production costs and estimated CO2 emission costs or alternatively grey hydrogen costs combined with CCS.
