Problem
Harnessing tidal energy for electricity generation has proven challenging due to the high costs and environmental impact associated with traditional tidal turbines, as well as their limited applicability to specific locations with strong tidal flows. Existing tidal energy solutions often struggle to achieve cost-competitiveness with other renewable energy sources like offshore wind, hindering widespread adoption.
Solution
Porpoise Power is developing a novel tidal energy generator that utilizes oscillating hydrofoil technology, mimicking the movement of a whale's tail to efficiently convert underwater currents into electricity. Unlike traditional tidal turbines, their system is designed to operate effectively in medium tidal flows (3-5 knots), expanding the range of viable deployment locations to include coastal areas in the UK, North Atlantic, Pacific, Indian, and South Pacific regions. The design aims to achieve a Levelized Cost of Energy (LCOE) competitive with offshore wind, while providing a predictable and reliable baseload power source. By enabling arrays to be located close to grid connections and demand centers, the technology minimizes transmission losses and infrastructure costs.
Target Audience
The primary target audience includes energy companies, grid operators, and coastal communities seeking predictable, cost-effective, and environmentally sensitive renewable energy solutions.
Features
- Oscillating hydrofoil design inspired by biomechanics for efficient energy capture in medium tidal flows
- Low-profile arrays, sitting less than 2m high on the water, minimizing visual impact and navigational hazards
- Reduced threat to marine wildlife due to fin movement at fish swimming speeds
- Scalable array deployments adaptable to various coastal environments and grid connection points
- Potential to deliver baseload power and balance grid fluctuations when combined with wind power
