Design concept for grid scale Porpoise Power tidal energy unit
Inspired by dolphin biomechanics, Porpoise Power’s oscillating hydrofoil system operates efficiently across diverse marine environments. Compared to conventional tidal turbines, it enhances energy output while prioritizing environmental compatibility. The technology aims to deliver stable baseload power at costs comparable to offshore wind, offering a consistent energy supply similar to nuclear power.
ZCC noted: “Critically, their breakthrough system makes tidal energy cost-competitive with offshore wind, but unlike wind, it can deliver predictable baseload power like much more expensive nuclear generation.” They further explained: “With this innovation, Porpoise Power unlocks the potential to meet the entirety of the UK’s baseload electricity demand from tidal power alone with just four 30 km x 30 km arrays.”
The company is advancing its technology through trials at UK tidal sites, focusing on optimizing the levelized cost of energy (LCOE) for large-scale deployment. Porpoise Power’s system is designed to support a stable, clean energy mix by complementing solar and wind, potentially reducing reliance on fossil-fuel peaking plants.
Led by CEO John Kennedy, previously involved with Green & Black’s, Wayfair, and Adlens, the founding team includes Adrian Thomas, Professor of Biomechanics at Oxford and Founder of Animal Dynamics, alongside Hilary Struthers, a former Shell executive, and Martin Hall, a marine systems engineer. ZCC commented: “We were particularly impressed by the strength and diversity of the founding team. The team combines deep technical credibility, a pragmatic commercial approach, and a strong climate mission.”
Porpoise Power is moving toward pilot deployments, supported by a UK contract for difference (CfD). The company plans to install grid-connected tidal generation capacity in the hundreds of kilowatts in its next development phase, contributing to a sustainable energy future.
ZCC emphasized the global potential: “These engineering advances unlock an order of magnitude more viable tidal sites globally.” By harnessing tidal energy’s predictability, Porpoise Power aims to play a key role in expanding renewable energy options worldwide.
