Caudal Energy

Caudal Energy is an Oxford-based company focused on developing a new class of predictable renewable power systems using tidal energy. They aim to challenge the traditional assumptions that tidal energy is complex, costly, and niche. Their approach combines smarter hydrodynamic design with modular deployment architecture to create a system designed for real-world performance. By unlocking the potential of mid-flow tidal sites, Caudal Energy believes it can dramatically expand where tidal energy can be deployed and how commercially competitive it can become. Their proprietary oscillating foil system is inspired by the efficiency of marine mammal caudal fins and works with tidal flows rather than against them, enabling a simpler, smarter, and more commercially scalable approach to marine energy generation. This system is designed to operate efficiently across a wide range of tidal flows and converts energy through hydrodynamic lift and motion, rather than traditional turbine rotation. Caudal Energy's technology is engineered to operate in flow speeds of 3 knots and above, with lower complexity and broader deployment potential, aiming to unlock 10x as many sites as traditional tidal systems.
