Majority-Owned Joint Venture Begins Biomass-Powered Steam Operations at Dairy Facility in South Africa, With Right of First Refusal on Future Projects

Dublin, May 11, 2026 (GLOBE NEWSWIRE) -- Fusion Fuel Green PLC (Nasdaq: HTOO) (“Fusion Fuel” or the “Company”), a leading provider of full-service energy engineering, advisory, and utility solutions, today announced that BioSteam Energy (Proprietary) Limited (“BioSteam Energy”), the Company’s majority-owned joint venture has completed installation and commissioning and commenced commercial operations for its first biomass-powered industrial steam project at a well-established dairy facility in South Africa. This project is expected to generate approximately $0.7 million in annual revenue with further potential projects in the pipeline.

Developed in partnership with Alien Fuel (Proprietary) Limited (“Alien Fuel”), the project establishes Fusion Fuel’s first operations in Southern Africa.
