Blue Shark Power System SA (MLBSP.PA) designs, assembles and deploys hydrokinetic turbines that convert kinetic energy from tidal currents, ocean waves, river flows and low-depth water movements into clean electricity; its core products include the patented Blue Shark horizontal-axis marine turbine with rated power outputs of 250kW to 1000kW for depths of 20m to 60m in currents of 1.5m/s to 3.5m/s, featuring self-orienting carbon fiber blades, diffusers and asynchronous generators connected via mooring to shore grids; and the Blue Shark Pillar twin horizontal-axis river turbine with rated power of 30kW to 700kW for shallow depths of 3m to 12m in currents of 2.5m/s to 4.5m/s, offering low-cost installation without heavy lifts, easy maintenance via winch systems and minimal environmental impact. Founded in 2002 and headquartered at 5 Allées de Tourny in Bordeaux, France, the company targets renewable energy developers, governments and public authorities in Europe, Africa, the Caribbean, USA and other regions lacking grid access, with operations focused on shallow waters, seas, oceans and rivers through direct sales, joint ventures or self-operated farms. In recent developments, it pursued a 2023 capital increase of EUR717,000 via debt conversion to acquire hydrokinetic licenses from US-based Blue Shark Energy LLC for complementary small-scale turbines of 30kW to 500kW deployable in weak currents, offsetting a matching capital reduction tied to returning a patent license to former shareholder Helios Gem Company; proposed a name change to Blue Shark Energy SA; advanced R&D for mass-produced carbon fiber blades and a new performance-enhancing patent; secured agreements in Africa for up to 15 turbines, the Caribbean for school electrification and with a British firm for financing; received 2023 Blue-GIFT project support for tidal device testing at France's SEENEOH site; and planned a first substantial tidal farm by 2025 amid investor talks and contracts in New Zealand, Jamaica and the UK.
