Hydrohub MW Test Centre

In it’s Routekaart Waterstof the Topsector Energie and the TKI Energie & Industrie is calling upon the industry to start working on several promising initiatives, e.g. “stress tests of large-scale electrolysers in an industrial setting including one fluctuating supply of renewable electricity”.

This project is a response to this ambition. It covers the design, realisation and exploration of a MW testing centre at the Zernike Campus in Groningen. The open-innovation infrastructure will be used to do research and perform series of stress testing at MW scale with water electrolysis (both alkaline and proton exchange membrane (PEM) as a stepping stone towards future GW scale production of sustainable hydrogen by the process industry. Material- and component suppliers for e.g. membranes, anodes, electrodes, pump etc. are facilitated to test the impact of their products. Since manufactures of electrolysers do not offer this transparency, this is a unique feature.

This project is a building block of our Hydrohub Innovation Program and therefore aligned to other hydrogen initiatives by the process industry and academics like the so-called GW-study and some mid-term projected pilot projects (e.g. 20 MW demo in 2022 by AkzoNobel and Gasunie) and a new tenure track programme by NWO in the field of electrochemistry.



Hydrohub GigaWatt Scale Electrolyser



In the energy system of the future a key role will be played by renewable electricity. This will feed the platform for green value chains with H2 as intermediate for products (e.g. via syngas platform or ammonia platform), for mobility, and for heating. The key technology in this value chain is H2
production via electrolysis. Hydrogen production via electrolysis is currently only done on a MW scale. However, to match the demand for hydrogen of the Dutch industry and play a significant role in buffering the future intermittent power supply, an enormous scale up is required of the electrolyser capacity to a GW scale. Yet, this scale up has not been put into practice so far. Therefore, the aim of this project is to explore the construction of such a GW plant in the Netherlands and address and overcome possible barriers for the realization. Stepping stones to achieve this are by: (1) putting a 1 MW test-centre in place to explore crucial elements of the process and by (2) feeding results into a series of conceptual design studies over the years leading towards a 1 GW electrolyser design that will be on par with current H2 manufacturing technologies in terms of Total Annualized Costs (TAC). Meanwhile, value and supply chain considerations will be studied as well to understand the role of large scale electrolysis capacity as key pivot player between supply of renewable electricity on the one hand and the off-take of H2 on the other hand by demand sectors like mobility, industry and heating.


Hydrohub HyChain – Energy Carriers and Hydrogen Supply Chain






  • Hydrogen is a key component to enabling a 95% reduction in industry CO2 emissions, though carbon-neutral H2
  • Production is an energy-intensive process
  • H2 can be used in applications that enable CO2 emission reductions in other industries
  • Carbon-neutral H2 is also a key part of decarbonizing those industries by 2050

This project focuses on developing the technology for small-scale energy storage and examining the commercial feasibility of such a system. This project answers all relevant questions that are needed to gradually work towards a pilot in the next phase. The aim is to produce an energy storage system (product) that can be used frequently and profitably. The outcome of the feasibility study also identifies the bottlenecks for implementation of such an energy storage system, and the scale on which it is economically feasible (at present). This insight also determines the follow-up steps.



The Power2Ammonia project was a feasibility assessment of using ammonia as an energy carrier, to store excess renewable power for use in a power plant during off-peak hours, or as a feedstock for the chemicals industry (for example in fertilizer production. The work was the result of a collaboration between the ISPT, Nuon, Stedin, Proton, ECN, CE Delft, AkzoNobel, OCI Nitrogen, the University of Twente, and TU Delft.

The ambition of the Power2Ammonia project was to gain an understanding of not only the economic feasibility of using peak renewable energy in ammonia and applications for ammonia, but also to understand how the full value chain would function, who would be involved in which roles, etc.

The feasibility was assessed for the case of Nuon’s Magnum power plant in Eemshaven.

The results of the study demonstrate that electrochemical ammonia production from renewables offers a promising pathway forward for storage and import of renewable energy as a means to handle intermittency of energy supply.

In the Power2Products project, a large number of parties worked together to examine how industry can contribute to the energy transition by exploring business cases for handling intermittency in energy production in energy-intensive industrial processes. The project was a collaboration between DOW, Akzo Nobel, Smurfit Kappa Roermond Papier, Avebe, Friesland Campina, Eneco, Delta netwerken, Zeeuwind, Enexis, Tennet, Industrial Energy experts, Cofely, RHDHV, Siemens, FME, VNCI, Netbeheer Nederland, Berenschot, and CE Delft.

The main aim of the Power2Products project was to gain insight into how energy-intensive industries can electrify energy demand and use flexible demand side management to produce products and contribute to stabilizing a grid with a large share of renewables.

The project involved a feasibility study for five business cases, looking at economic and social costs and benefits to understand under which conditions the options explored would make sense to implement. Three of the business cases focused on flexible power to heat, one on “peak shaving” (designing for flexible demand or storage of energy to consume when energy prices are low), and one on upgrading low-pressure steam to high-pressure steam using vapor recompression.

The result of the work was a report showing the results of the five business cases, along with all of the assumptions, the context of the electricity system, and a technology assessment.
