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.
