Technology Overview

It’s in the Water

The movement of the world’s water – whether in open water or inland – provides a vast store of kinetic energy, which can be harnessed to generate electricity. An unprecedented opportunity exists to capture untapped in-stream resources that were previously unattainable in canals, rivers and marine environments. Instream’s technology allows customers to use renewable energy in a cost-competitive manner with minimal environmental impact, resulting in a smarter way to generate clean electricity.

A Better Solution – Hydrokinetic Power Generation

Instream is developing a complete hydrokinetic power solution consisting of groupings (or “arrays”) of vertical access hydrokinetic turbines (VAHTs), simple, low-cost devices that convert the kinetic energy in moving water into electricity.

Instream hydrokinetic power generation technology has the ability to produce energy without the need for dams, diversions, or reservoirs. This allows for a water-based renewable energy source with less environmental disruption, a lower cost of engineering, construction and maintenance, less safety risk, and reduced regulatory issues.

Instream’s pilot projects provide valuable insight into the interactions between multiple turbines. The data obtained will allow Instream customers to optimize multi-turbine installations specific to their location needs.

The Engineered Advantage

Instream’s versatile technology is applicable in both inland water and near-shore tidal applications inaccessible to conventional technologies. The use of smaller turbines and standardized support structures allow for commoditization and cost effective deployment and maintenance. Networking devices together allows projects to scale to any size. A non-submerged system is more cost effective and simplifies deployment. Instream’s turbines have the drivetrain and electronics above water which reduces risk and improves access for maintenance.
