Revenue model
- TidalKite System Sales: SeaQurrent plans to enter the tidal energy market by selling TidalKite systems installed in farms. Each TidalKite unit has ~0.5 MW capacity and farms range from a few MW to hundreds of MW. Revenue is generated from the sale and installation of complete TidalKite systems to project developers, utilities, energy cooperatives, and island communities. The company is pre-commercial, currently in demonstration phase at Ameland.
- Electricity Sales to Local Cooperatives: Through Getijdencentrale Waddenzee (Tidal Power Plant Waddenzee), SeaQurrent plans to supply electricity generated by TidalKite installations to local energy cooperatives, who in turn supply electricity to residents. This enables co-ownership models and local energy distribution in island and coastal communities.

SeaQurrent product offering
Product offeringCore offering
SeaQurrent designs, develops, and plans to sell the TidalKite System — an underwater kite that harvests hydrokinetic energy from tidal and ocean currents to generate renewable baseload electricity. Each multi-wing TidalKite unit has approximately 0.5 MW capacity, is anchored via tether to a seabed hydraulic Power Take-Off (PTO), and is deployed individually or in modular farms ranging from a few MW to hundreds of MW. The system is engineered for shallow waters and low-velocity tidal channels inaccessible to conventional tidal turbines.
Product overview
SeaQurrent offers a single unified product: the TidalKite System, an underwater tidal energy kite. The system comprises a multi-wing TidalKite unit, a mooring anchor, a tether cable, a hydraulic Power Take-Off (PTO) energy converter, a submarine power cable, and a remote monitoring and control unit. Each TidalKite unit has a capacity of 0.5MW and measures 9 by 12 meters. The company deploys these units individually or clusters them into TidalKite farms for larger power generation projects.

SeaQurrent competitors and assessment
Company assessmentDirect peers
- Minesto: Swedish developer of the 'Deep Green' underwater kite tidal power system — the most direct analogue to SeaQurrent's TidalKite. Both use a tethered, hydrokinetic, low-velocity-current device with a figure-eight flight pattern connected to a seabed PTO. Minesto is further along in commercialisation but shares the same fundamental technology approach and target market (utility-scale tidal baseload).
- Orbital Marine Power: Scottish floating tidal-stream turbine developer (O2 device, 2 MW class). Operates in the same European tidal stream power sector as SeaQurrent, targets utility-scale tidal farms in Scotland and Norway, and is one of the more advanced marine-energy technology companies by hours of grid-connected operation. Both compete for the same 1GW-by-2030 EU ocean-energy mandate.
- SIMEC Atlantis Energy: UK-based marine-energy developer behind the AR1500/AR2000 tidal stream turbines deployed at MeyGen (Pentland Firth). Competes directly with SeaQurrent in the offshore tidal stream generation market and was an early commercial mover, though it has faced restructuring risk that highlights the sector's capital-intensity challenges.
- Nova Innovation: Scottish seabed-mounted tidal turbine developer with grid-connected arrays in Shetland (Bluemull Sound). Directly comparable as a developer of multi-turbine tidal arrays targeting predictable, dispatchable tidal power for islands and utilities — the same primary use-case SeaQurrent's Wadden Sea deployment targets.
- Ocean Renewable Energy Company (ORPC): US-based developer of tidal and river current systems, including a partner in SeaQurrent's SHINES consortium via ORPC Ireland. Comparable low-velocity current focus and is one of the more progressed hydrokinetic developers with US and EU deployments, including data-centre and island applications similar to SeaQurrent's go-to-market.
Broad incumbents
- ANDRITZ Hydro Hammerfest: Subsidiary of the ANDRITZ Group developing the HS1000/HS3000 horizontal-axis tidal stream turbines, deployed at EMEC and MeyGen. Acts as a broad incumbent in the same tidal energy space, offering competing turbine-based solutions with a much larger industrial backing and grid-scale track record.
Emerging players
- Magallanes Renovables: Spanish floating tidal platform developer (ATIR). Targets similar utility-scale tidal stream generation with a competing floating-platform architecture. A niche but directly competing technology that, like SeaQurrent, is still in pre-commercial demonstration and seeking scaling capital.
- CorPower Ocean: Swedish wave-energy developer with a point-absorber WEC technology. Operates in the adjacent marine renewable energy category, pursues the same Northern European policy tailwinds (SHINES co-funding, EU targets), and pursues similar data-centre/island commercial pathways, though wave-energy differs from tidal current capture.
- Carnegie Clean Energy: Australian developer of the CETO wave-energy technology. Competes for the same marine-renewable policy and capital pools as SeaQurrent, offers a different wave-driven architecture, and represents the broader 'marine energy' thematic rather than direct technology overlap. Useful comparable for marine-energy commercialisation timelines and capital intensity.
Regional players
- Sustainable Marine Energy (now part of HydroQuest): France-based tidal stream developer with floating platform technology historically deployed in the UK and Canada, now integrated into HydroQuest's marine renewables business. Regional_European player addressing the same Paimpol-Bréhat / Channel Islands / French Atlantic sites SeaQurrent's TidalKite is targeting via SHINES, making them a near-term competitive overlap in France.
