BrightHy Solutions completed the Front-End Engineering Design ("FEED") package for the Hydrogen Production Unit at a previously announced 15 MW industrial green hydrogen production facility in southern Europe. Once operational, the facility is expected to produce green hydrogen for blending into the natural gas network, which the Company believes will support the region’s transition toward cleaner energy systems. The Company believes that completion of the FEED package represents an important execution milestone for the project and provides the client with the technical framework to proceed with EPC tendering and the next phase of development. In addition, BrightHy recently completed Factory Acceptance Tests ("FAT") for major equipment packages associated with a previously announced hydrogen refueling station project, also in southern Europe. BrightHy's engineering team traveled to China to oversee testing alongside equipment suppliers Sungrow Hydrogen and Houpu Global Clean Energy. Following the completion of the FAT process, the Company has received confirmation that the equipment has been shipped and is in transit to the project facility, where it is expected to be installed as the project advances toward commissioning. Frederico Figueira de Chaves, Chief Executive Officer of Fusion Fuel and BrightHy Solutions, commented, “These milestones reflect what we believe is BrightHy's ability to execute on complex hydrogen infrastructure projects and turn commercial opportunities into tangible project progress. The completion of FEED engineering for the green hydrogen production facility and the FAT process for the hydrogen refueling station project represent important execution milestones that we believe move both projects closer to deployment. As we continue to expand our engineering and project delivery business, we remain focused on disciplined execution, supporting our customers' decarbonization objectives, and building long-term value through the successful delivery of hydrogen infrastructure projects.” About Bright Hydrogen Solutions Limited Bright Hydrogen Solutions Limited is a wholly owned subsidiary of Fusion Fuel Green PLC focused on hydrogen through electrolysis solutions.
