Superior Technology for a Carbon Free World

Sigma Energy has revolutionized renewable energy with the Sigma Wave Energy Converter. Learn more about this pioneering technology.

Proven Performance in the Adriatic Sea

In July 2022, Sigma Energy successfully deployed its 30-kW Sigma WEC prototype in the Adriatic Sea, demonstrating exceptional resilience and efficiency.

Operating in all weather conditions, including storms, the device fed continuous electricity into the Montenegrin grid for six months while being monitored by the Sigma Energy Monitoring Centre.

  • Operated optimally at a wave height of 2.6 meters and withstood waves up to 6 meters.
  • Demonstrated 35% efficiency, proving its readiness for 3 MW ocean deployments.

The trials confirm that Sigma Energy is ready to scale its technology for ocean waves, making it a reliable solution for global energy needs.

Innovations for Technological Excellence

Sigma Energy has revolutionized renewable energy with the Sigma Wave Energy Converter (Sigma WEC). This cutting-edge device converts the vertical motion of waves into electrical energy using a proprietary mechanical Power Take-Off (PTO) system.

Years of research, custom software analysis, and rigorous testing have demonstrated the Sigma WEC’s unparalleled performance and efficiency.
A major breakthrough in wave energy technology, Sigma Energy successfully deployed a 30-kW full-scale Sigma WEC prototype offshore in Montenegro, connecting it to the electricity grid.

This achievement validated its compliance with International Energy Agency’s Ocean Energy Systems (IEA-OES) guidelines and showcased its readiness for commercial-scale deployment with 3 MW devices.

Unlike submerged alternatives, the Sigma WEC operates at the ocean surface, enabling it to capture maximum wave energy for optimal efficiency.

This surface-level functionality, combined with patented technologies, positions Sigma Energy as a leader in sustainable, grid-compatible wave energy solutions.
