HANNOVER TRADE SHOW 2026

Sunfire supports the joint OPC UA Working Group Hydrogen Electrolyzers to develop a standardized, manufacturer-independent information model based on OPC UA to enable:

• Low-effort integration of electrolyzers into automation systems,
• Interoperable communication across vendors,
• Uniform access to operational, maintenance, and system data over the whole lifecycle,
• Modular hydrogen system composition.

Sunfire Product Showcase:

• At the Hannover fair the working group presents the development progress on the OPC UA Companion Specification for Hydrogen Electrolyzers: A formal, machine-readable information model defining data structures, interfaces, and services for all major Electrolyzer types, published as a NodeSet file compatible with any OPC UA-compliant system.
