Hydrogen Generators Using Water Electrolysis – Part 2: Testing protocols for performing electricity grid services

 


Scope

This technical report describes testing protocols for water electrolyser systems with the focus on alkaline and PEM water electrolysers. The purpose of these protocols is to determine if an electrolyser has the basic capabilities of providing electricity grid service. It also covers test apparatus, measuring instruments and measuring methods, and evaluates test reports for electrolyser systems.

 

Hydrogen generators that can also be used to generate electricity, such as reversible fuel cells, are excluded from the scope of this document.

 

testing guidance” (and the term “guidance” is used because this is a TR) is explicitly for the purpose of electric grid balancing. Essentially, an electrolyser here is being treated as a black box that must perform by TSO/DSO/IESO requirements. So, the objective of testing is to check whether this “black box” can provide this external service. Electrolyser design and H2 generation are outside the scope.

 


Status

Initiated in 2020.
