Portable Underwater Generator (PUG®)

Challenge assumptions; exceed expectations

A system that is deployable to locations with flowing water. One that is easy to maintain, durable, and has a small environmental footprint.

A design that scales to meet the needs of a small team in the wilderness or a large city along the coast. Our Portable Underwater Generator will have you rethinking renewable energy.

Deployable

  • PUG is a hydroelectric generator that is equally capable in inland rivers as it is in offshore, saltwater applications.

  • Anchoring and ballasting systems allow for deployment by common marine service technicians and vessels.

Maintainable

  • Our proprietary on-demand-buoyancy enables routine maintenance to be performed without specialized equipment.

  • Modular assemblies and generous access along the hull allow for efficient upkeep, which maximizes generator uptime.

Scalable

  • Based on extensive research and computational fluid-dynamics (CFD) analysis. This baseline allows PUG to be scaled in size and power output.

  • Both a single-operator, mobile system (PUG-Lite®) and a utility-scale system (CHUTE®) share form, fit, and function.

Affordable

  • Striving for the lowest levelized cost of energy (LCOE).

  • Molded composite construction, commercial off-the-shelf (COTS) hardware, and watertight, embedded components make for lower construction, deployment, and operational costs.

  • High efficiency and reliability.

Durable

  • The self-clearing, protective grate system keeps the flow of water efficient, while protecting components from damage.

  • Proprietary surface coatings keep biofouling at bay.

  • PUG’s unique anchoring system allows for effective diversion of obstructions and debris, protecting the generator and ensuring maximum uptime.

Sustainable

  • Usable asset life substantially exceeds other renewable technologies.

  • Rotor design that does not harm sea life.

  • Zero permanent underwater installation mean PUG system can be fully removed and redeployed without lasting impact to the environment.
