Breaking ground in the energy sector with subsea kite technology

Marine energy developer Minesto has verified the functionality of its Deep Green technology at utility scale. The technology generates clean electricity from tidal streams and ocean currents, and developer Minesto has successfully ‘flown’ its marine energy kite in full subsea trajectories at the Holyhead Deep site eight kilometres off the coast of Holyhead, North West Wales. 

Commenting on the milestone, Minesto’s CEO Dr Martin Edlund said: “This is a ground-breaking moment for the marine energy industry and a great accomplishment made possible by everyone that has been involved in the development of our Deep Green technology and the DG500 system now deployed in Wales. It is a world’s-first achievement that confirms the functionality of our patented concept at utility scale while it also reassures the fact that our technology expands the ocean energy potential and forms an essential complement to established renewables.”

Using the same principle as flying a stunt kite across the wind, Minesto’s marine energy kite flies across the underwater current, significantly enhancing the water flow speed through the turbine. This makes Minesto’s product commercially viable in globally extensive sea areas where no other known, verified technologies can operate cost effectively.

Edlund explained: “With our light-weight system we exploit low-flow currents, offering energy players globally a secure and affordable way to produce renewable baseload power.”

Listed on Nasdaq First North Stockholm since 2015, Minesto has funded the development of its Deep Green technology through a mix of private equity and public grants. With substantial support from the European Regional Development Fund through the Welsh European Funding Office (€13m) and InnoEnergy (€4.5m), Minesto and the Deep Green technology is reportedly the EU’s largest investment in marine energy to date.

Minesto will now continue with further testing before moving to the second commissioning phase to verify the power take-off system and electricity generation.
