Porpoise Power are developing a tidal generator, using the movement like a whale’s tail. Unlike tidal turbines, it works in medium tides, 3-5 knots, which are abundant around the coasts of the UK, North Atlantic & Pacific coasts, plus Indian and South Pacific. Its arrays will generate energy at the same cost as offshore wind.

The potential for this technology to balance the grid is huge – in the UK it could deliver all the required baseload power, globally tidal could have 250GW of generation in the water by 2050, replacing gas and eliminating 500 million tonnes of carbon dioxide emissions per year.
