Sperra designs and manufactures structural systems for offshore renewable energy projects using 3D concrete printing to create anchoring and foundation components for floating solar, offshore wind, and wave energy. On-site large-scale 3D printers lay and cure custom parts from local materials, cutting transport emissions and lowering costs. Unlike competitors, Sperra combines marine engineering expertise with 3D printing and local-material sourcing to provide tailored, project-based services. Its goal is to lead the marine renewable energy sector by delivering practical, scalable, and eco-friendly foundation solutions for offshore projects.

Germany Trade & Invest highlights PLEUGER's role in pioneering underwater energy storage. Engineering Expertise Behind the StEnSea Energy Storage Project PLEUGER's contribution to the innovative StEnSea (Stored Energy in the Sea) project has been highlighted by Germany Trade & Invest (GTAI), recognizing the collaboration between research and industry that is driving new approaches to renewable energy storage. Led by Fraunhofer IEE and supported by the project partners Sperra and PLEUGER, the StEnSea project explores an innovative approach to storing renewable energy using large concrete spheres installed on the seabed. During periods of excess renewable electricity, seawater is pumped out of the sphere and stored as potential energy. When electricity is needed, seawater flows back into the sphere through a pump-turbine system, generating power. The heart of the system At the core of the StEnSea concept is PLEUGER's expertise in submersible pump technology. "The pump is the heart of the StEnSea project," says Edris Faez, Head of Sales at PLEUGER. Operating reliably in seawater at depths of around 600 metres presents unique engineering challenges. Drawing on decades of experience in designing and manufacturing submersible pump systems for demanding applications, PLEUGER was selected as the project's pump partner to help develop a solution capable of performing in these extreme conditions. Innovation through collaboration StEnSea demonstrates what can be achieved when research institutions and industry combine their expertise. Together with Fraunhofer IEE and Sperra, PLEUGER is helping advance an innovative energy storage concept that could support the integration of renewable energy and contribute to a more sustainable energy future. Pleuger Industries GmbH is proud to be part of this pioneering project and thank its partners for their continued collaboration. August 11, 2026
