Technology

Two machines, one job: turn moving water into electricity.

DeepBluePower designs and builds submerged turbines for two distinct marine energy sources — fast tidal streams and steady ocean currents — sharing a common electrical and control platform.

TIDAL STREAM CLASS

The Current-1 turbine

A horizontal-axis turbine anchored to a seabed foundation in tidal straits and channels, where the twice-daily tide accelerates through a narrow passage. Twin contra-rotating rotors cancel torque reaction, keeping the foundation load low and steady.

Blades pitch automatically to face the flow as the tide reverses direction, so the turbine generates on both the flood and the ebb tide — twice per cycle.

OCEAN CURRENT CLASS

The Abyssal-1 array

A moored, mid-water array designed for slower, near-constant boundary currents. Rather than one large rotor, Abyssal-1 uses a cluster of smaller turbines on a single mooring line, simplifying installation and letting individual units be serviced without lifting the whole array.

Buoyancy-tensioned mooring keeps the array at its target depth regardless of tide-driven changes in sea level.

Process

From moving water to grid power

STEP 1 · CAPTURE

The rotor turns with the flow

Current or tidal flow drives the rotor at low RPM — typically under 15 revolutions per minute, slow enough that marine life and vessels have ample time to detect and avoid it.

STEP 2 · CONVERT

A sealed nacelle generates power

A direct-drive permanent-magnet generator inside a pressure-sealed nacelle converts rotor torque directly into electricity, with no gearbox to maintain.

STEP 3 · TRANSMIT

Power moves through a subsea cable

An armored subsea cable carries power from each unit to a shared junction, then to shore, where it's stepped up to grid voltage.

STEP 4 · SCHEDULE

Output is forecast, not guessed

Because tidal timing is astronomically predictable, grid operators receive an hour-by-hour generation forecast months to years ahead — closer to a train timetable than a weather forecast.

In context

How ocean power compares

Every renewable source has a role. Here's where tidal and current power earn their place in the mix.

Source Predictability Availability Visual footprint
DeepBluePower tidal / current Years ahead ~90–100% of the time None — fully submerged
Offshore wind Days ahead ~35–45% of the time Visible turbines above surface
Solar Hours ahead ~20–25% of the time Land or rooftop area

Figures are industry-typical ranges for illustration; site-specific yield depends on local flow speed, channel geometry, and array configuration.
