Interoperability Profile Recommendations for Hydrogen Assets (TR 128)

Hydrogen assets like electrolyzers and fuel cells are being installed in distribution and transmission systems to store and use excess electricity from renewable resources. Installing these hydrogen assets in an interoperable way will reduce the cost of integration with existing intelligent assets and enable successful installation and operation in cost -effective and timely manner. In this technical report, we use existing interoperability standards and provide recommendations to the hydrogen assets installers and users for appropriate use of these standards. This report also provides data models that can be borrowed by end users to enable interoperable communication with their hydrogen assets. This report showcases example operation of interoperable intelligent devices that exchange information to and from the hydrogen assets. The data models showcased in this work are available in open-source for users to download and replicate the experiments presented in this report.
