QualyGridS project – represented by Regine Reissner

Nominated by NEN - Nederlands Normalisatie-instituut

Jan 2017 – June 2020

 

 

The project QualyGridS developed standardized and unified testing protocols for water electrolyzers, with which an electrolyzer’s ability to perform grid balancing services can be demonstrated. Requirements of various countries to electrolyzers are converted in tests which show the capability of the electrolyzer to perform a particular grid service. Further, several business cases of electrolyzers performing these services have been analysed.

The impact of the testing protocols and techno-economic analysis in the project is to make available  qualification tests for electrolyzers to manufacturers and their customers, to show possible business models and thus to prepare the market for electrolyzers being integrated in electricity grid services.

The EU Green Deal boosts the uptake of renewable energies in the EU energy system. As the share of renewables in the energy mix is rising, the need for grid balancing services becomes increasingly urgent. Renewable electricity (e.g. sun and wind) is a more unstable source than conventional energy sources. To maintain grid stability, production of electricity needs to equal consumption.

Electrolyzers have the potential to play a key role in grid balancing. The flexibility of water electrolyzers (WE) to balance the grid by producing hydrogen with surplus electricity or reducing their power consumption is case of a grid overload may be offered to TSOs for example as frequency containment reserve (FCR), frequency restoration reserve (FRR), or to DSOs for congestion management and voltage control among others. Grid services may contribute as a secondary revenue stream to electrolyzer owners to achieve the goal of competitive hydrogen prices and bolster the market entry of electrolyzers.

Above all, the QualyGridS project supports the ambitious sustainability aims of the EU by building forward to the development of a stable grid for renewable electricity, and by providing manufacturers and customers (TSO/DSO) with a powerful and standardized tool with which this capability of electrolyzers can be demonstrated.
