Hydrokinetic Energy: Clean Power from Moving Water

​​

Predictable Renewable Energy, Beneath the Surface

Rivers, tidal streams, and ocean currents contain enormous amounts of renewable energy. Unlike sunlight and wind, moving water is highly predictable and, in many locations, available throughout the day and night.

Swordfish Energy is developing a new way to capture this energy using the patent-pending Swordfish Compeller, a submerged hydrokinetic system designed to generate clean electricity without dams, reservoirs, fuel, or major water diversion.

 

The Power of Moving Water

Hydrokinetic energy is produced from water that is already moving naturally. Instead of holding water behind a dam, a hydrokinetic system is placed directly within a suitable current.

Water is more than 800 times denser than air. This allows a relatively compact underwater system to access substantial energy, even when the current appears calm at the surface.

Hydrokinetic energy can be generated from:

• Free-flowing rivers

• Tidal channels

• Coastal passages

• Ocean currents

• Industrial water channels

Tidal movements can be forecast far in advance, while many rivers provide long periods of consistent flow. This predictability makes hydrokinetic energy a valuable complement to wind and solar generation.

 

Introducing the Swordfish Compeller

The Swordfish Compeller is not a conventional propeller-style turbine.

Its distinctive design uses five hydrodynamic wings positioned around a central nacelle. As water flows along the Compeller, the wings convert the movement of the current into slow, powerful rotation that is used to generate electricity.

The Compeller is designed to operate quietly below the surface, where it remains largely out of sight and protected from many surface weather conditions.

Its modular design allows each system to be adapted to the characteristics of its deployment location, including water velocity, depth, available space, and electricity requirements.

 

Designed for Practical Deployment

Swordfish systems are being developed for straightforward installation, retrieval, and maintenance.

Depending on the location, a Compeller may be installed on a self-leveling seabed cradle or incorporated into another marine structure. This approach can reduce the need for extensive underwater construction while allowing major components to be retrieved for inspection and servicing.

Individual Compellers can serve local energy requirements or be connected in arrays to support larger projects. The electricity produced can be delivered directly to a community, industrial facility, microgrid, energy-storage system, or utility network.

Potential applications include:

• Remote and Indigenous communities

• Coastal municipalities and islands

• Ports and marine terminals

• Industrial operations

• Offshore infrastructure

• Data centres

• Clean-water and green-hydrogen production

• Utility-scale renewable-energy projects

 

Environmental Responsibility

Swordfish Energy believes that clean electricity must be produced responsibly.

The Compeller generates electricity without combustion and without the ongoing emissions, air pollution, fuel transportation, or spill risks associated with diesel generation. It requires no dam, reservoir, or major alteration of a river system.

The system is designed for slow rotation, quiet submerged operation, and minimal visual impact. Careful site selection and environmental monitoring are essential to protecting fish, marine mammals, aquatic habitats, navigation, and other water users.

Swordfish works toward an approach in which renewable-energy development respects both the natural environment and the communities that depend upon it.

​

From Individual Systems to Clean-Energy Arrays

The Swordfish Compeller is designed as part of a complete, scalable energy platform.

Multiple units can be connected with energy storage and remotely managed microgrids to provide electricity where it is needed. This makes the technology suitable for projects ranging from local community power to large multi-megawatt energy arrays.

By generating electricity close to the point of use, hydrokinetic energy can reduce dependence on imported fuel, strengthen local energy security, and create new opportunities for community and regional ownership.

 

Building Energy Sovereignty

Much of the world’s moving-water resource remains undeveloped. Swordfish Energy is working to transform this predictable natural movement into dependable, locally produced electricity.

The objective is simple: clean power without dams, combustion, or extensive land use.

Clean. Safe. Secure.

Energy equals sovereignty.
