Problem
Current renewable energy sources like wind and solar are intermittent and require extensive grid balancing, while existing tidal technologies are complex, expensive, and limited to a few high‑flow locations, restricting their contribution to reliable baseload power.
Solution
Caudal Energy develops a fin‑based tidal power system that converts the kinetic energy of mid‑flow tidal currents into predictable, continuous electricity. The technology uses modular, cost‑efficient hardware that can be deployed at a wide range of abundant tidal sites, not just extreme high‑flow locations. Because water density is over 800 times that of air, tidal flow provides a highly energy‑dense resource that can be forecast years in advance, enabling stable generation that supports grid reliability and reduces balancing costs. The system is designed for practical installation and operation, allowing utilities and renewable developers to scale tidal generation to commercial levels.
Target Audience
Primary customers are electric utilities, grid operators, and renewable energy developers seeking reliable, low‑carbon baseload power from marine resources.
