Ceres Power describes itself as a leading developer of clean energy technology, operating an asset-light licensing model across two core product areas: solid oxide fuel cells for power generation and electrolysers for green hydrogen production. The company holds licensing partnerships with major global corporations including Doosan, Delta, Denso, Shell, Weichai, Centrica, and Thermax. Its technology is positioned to serve AI data centre power demands, commercial and industrial applications, and emissions-intensive industries such as ammonia production, steelmaking, and electrofuels.

BlackRock's Multi-Entity Chain Reflects Complexity of Institutional Shareholding Structures

The notification lists BlackRock, Inc., incorporated in Wilmington, USA, as the ultimate controlling person across six separate ownership chains. Controlled undertakings through which the voting rights are held include BlackRock Investment Management (UK) Limited, BlackRock Institutional Trust Company, BlackRock Fund Advisors, BlackRock Advisors (UK) Limited, and BlackRock Asset Management Canada Limited, among others. The filing was completed on 9 November 2026 at BlackRock's London address at 12 Throgmorton Avenue. Such multi-chain structures are common for large global asset managers operating across numerous fund vehicles and jurisdictions, and the notification itself does not indicate any change in investment strategy.
