CSIR-SERC unveils hybrid floating platform for wind and solar

CSIR-Structural Engineering Research Centre (CSIR-SERC) in Chennai has developed a hybrid floating platform that generates both wind and solar power from a single structure. The system can be deployed in offshore and inland water bodies, unlocking new surfaces for clean energy.

The platform combines horizontal-axis and compact vertical-axis wind turbines with solar PV panels. Vertical turbines are placed between the larger horizontal units to capture wind from all directions, improving space use and total output. Its “partially compliant configuration” ensures the structure is strong enough to support equipment while flexing with waves to prevent damage.

The design builds on CSIR-SERC’s earlier work on semisubmersible floating wind platforms and modular floating solar PV systems. Extensive laboratory and numerical testing validated the hybrid platform. N Anandavalli, director of CSIR-SERC, said it offers a practical solution to expand India’s renewable energy capacity using offshore and inland water surfaces.
