Sizable Energy Validates Full System in At-Sea Proof of Concept at NOEL

Sizable Energy has successfully completed its scaled Proof of Concept (PoC) campaign, hosted at the Natural Ocean Engineering Laboratory (NOEL) of the University of Reggio Calabria. This major milestone provides the first complete, at-sea validation of the company's fully assembled energy storage system.

The experimental campaign, conducted between March and July 2024 in NOEL's unique natural wave basin, tested all of Sizable’s core components operating together. The system included the upper and seabed reservoirs, the connecting penstock, and reversible pumps, all functioning in a scaled-down, real-world oceanic environment. The test successfully demonstrated the full charge and discharge cycle using brine as the gravitational fluid.

This achievement marks a critical step in Sizable Energy's development roadmap, confirming the integrated performance, design, and operational procedures of the entire system. Preliminary data on the system's motion have also shown full compliance with expected values, further validating the robustness of the hydrodynamic design.

"Successfully testing the entire system in a real-world sea environment is a major step forward for Sizable Energy," said Dr. Manuele Aufiero, CEO and Co-Founder of Sizable Energy. "This campaign at NOEL moves us beyond individual component validation to proving the integrated system works exactly as designed. The insights gained are invaluable as we advance toward full-scale deployment."

Sizable Energy extends its sincere thanks to Prof Felice Arena, Prof Vincenzo Fiamma and Carlo Ruzzo, and the entire supervising team at the Natural Ocean Engineering Laboratory (NOEL) for their exceptional support and invaluable technical partnership throughout this critical validation campaign.
