Investment value proposition

It is well understood that a global commercial opportunity exists for any renewable energy device that can reliably produce electricity from tidal or wave energy sources at a cost comparable to that of existing electricity-generation technologies. From an environmental perspective, it would also contribute towards our global aspiration to help lower the greenhouse-gas emissions of the planet.

Our turbines convert both wave and tidal energy into electricity, thereby increasing the accessible energy density at locations closer to high population centres. When combined with our turbines' shallow-water performance and low visual impact, this approach significantly reduces project capex. Further reductions in capex are achieved by the use of deadweight anchors floated into position, an intra-turbine power-cable arrangement that eliminates seabed trenching, and our floating turbine design that minimises installation costs. These design features are projected to deliver a levelised cost of energy (LCOE) that significantly outperforms those of our marine-energy competitors and will compete with offshore wind on strike price whilst improving reliability of supply.

Equally important is the socio-environmental impact of our turbines. This is minimal as the turbine design has a very low tip speed that will not harm the local fish or mammal populations. The semi-submersible design is also comparatively unobtrusive with a visual impact similar to a yacht sail. When the minimum water depth requirement of 12 metres is also taken into account, it is likely that locations such as the Bristol Channel could therefore become accessible. It is also thought that our technology is a realistic alternative to the unpopular Tidal Barrage proposal that would extend between England and Wales. Our technology is also suitable for deeper water locations, such as the English Channel and the West Coast of Scotland.
