Final Electrolyser Array Arrives for 100 MW Hamburg Green Hydrogen Hub
Siemens Energy has delivered the final electrolyser array for the 100 MW Hamburg Green Hydrogen Hub at the former Moorburg coal-power site in Germany. The delivery marks a major construction milestone as the project moves toward installation and commissioning of its hydrogen-production technology. The electrolyser arrays were manufactured at Siemens Energy’s Berlin gigafactory. Hamburger Energiewerke and Luxcara are developing the project, which will convert part of the former thermal-power site into a renewable-hydrogen production centre. The 100 MW plant is intended to supply green hydrogen to industrial customers through Hamburg’s emerging hydrogen infrastructure. Reusing the Moorburg site gives the project access to established energy infrastructure while demonstrating the conversion of former fossil-generation assets into clean-energy hubs.
Aspen Power Secures Tax Capital for Up to 30 US Community Solar Projects
Aspen Power has secured a tax-capital commitment covering Investment Tax Credits generated by up to 30 community solar projects planned for 2026–2027 across several U.S. states. The transaction was structured through Basis Climate and Excelsior Energy Capital, whose partnership is targeting up to $150 million annually in minority-equity investments in distributed solar and battery-storage projects. Aspen owns and operates more than 300 MW of assets across 10 states and intends to retain the new community solar projects for long-term operation. The portfolio will supply residential and commercial subscribers. Consolidating up to 30 projects under a single underwriting and closing process is designed to accelerate tax-credit monetisation and release capital for construction of additional distributed-generation capacity.
Gore Street Capital Acquires 195 MW / 390 MWh Irish Battery Portfolio Gore Street Capital’s GS EU Fund has acquired two ready-to-build Irish battery projects totaling 195 MW / 390 MWh. The portfolio comprises the 120 MW / 240 MWh Kilmannock project and the 75 MW / 150 MWh Mucklagh project. Both have secured land, planning permission and grid connections and initially provide two hours of storage, with potential expansion to four hours. Kilmannock is expected to reach commercial operation in Q1 2028, followed by Mucklagh in Q2 2028. The projects are the first investments by GS EU in Ireland, where Gore Street already operates 130 MW across three projects. Ireland is targeting more than 80 percent renewable-electricity penetration by 2030, increasing demand for storage and grid flexibility.
