AXL ocean-current turbine
A moored horizontal-axis turbine for the tidal channels of the British Columbia coast. Predictable output. Minimal visual footprint. No dam, no reservoir, no relocation.
Anchoring, depth, and tidal windows
Each AXL ocean unit is moored with a redundant anchor system sized for the site's peak current and seabed type. The nacelle floats above the seabed in the high-velocity layer of the water column, where tidal kinetic energy is densest. Power is routed ashore via an armoured subsea cable.
BC tidal channels are among the best-characterized current regimes on the Pacific coast, which means output is highly predictable. Unlike wind, we know months in advance when power will be generated, which makes planning a microgrid a lot easier.
Use case: BC coastal communities
Remote coastal communities and First Nations villages currently rely heavily on diesel generation. A small AXL ocean array in a nearby tidal channel can displace a meaningful share of that diesel, reducing both operating cost and emissions, while keeping the asset under local control. We design deployments to be serviceable with locally available marine trades whenever possible.
Environmental footprint
- No dam, no reservoir, no upstream impoundment.
- Slow-turning rotor, engineered for marine life clearance.
- Anchors and cable routes sited with environmental review partners.
