How it works

Our technology

With a strong history of development and innovation in the renewable energy field, Repetitive Energy Company (REC) has developed a water-based turbine which is easier to deploy and maintain, repair and replace.

Unlike traditional water-based devices, the Vertical Axis Turbine will work in slower and shallower flows extending the range of environments that it could work in. The development of our technology is aligned closely with that of proven devices, but has a lesser risk of downtime and lower O&M than those already on the market.

After seven years of extensive research, REC has completed a critical stage in the development of our tidal stream turbine intended for deployment in a tidal array. As well as being fully scalable, it is capable of micro-generation for power storage and direct power production from various different waterways, reaching anything from 5Kw to 1/2MW depending on flows, device size and gearing.

SmartStream in action

Location agnostic - can be deployed where traditional turbines cannot operate
Unique as its self-starting, omni-directional and works with water turbulence
Scalable and flexible
Low-cost construction and simple to deploy
Low maintenance
Effective in shallow turbulent flows
Variable layout arrangements
Operation efficiency comparable to more expensive traditional horizontal axis turbines
Simple drivetrain, modular design and no specialist parts
Designed to work in flows from 1.2m/s up to 5m/s

Working smarter in the stream

Smartstream is an innovative new technology that harnesses the natural power contained within water.

The turbine has been developed to operate in some of the most challenging waterways and can be deployed in existing hydroelectric stations, rivers, streams and tidal areas.

The turbine is easy to deploy and requires a minimal amount of civil infrastructure. It’s low cost construction and high rate of return sets Smartstream apart from other forms of hydrokinetic generation.

Tidal deployment has the following benefits

Already an established and expanding sector in the renewable energy market
A predictable and reliable global source of energy
An assured, affordable and non-polluting alternative for island communities currently using diesel generators
Huge global tidal stream potential as shown on the slide below

Medium-scale surface deployment of SmartStream

A simple barge mooring system for station keeping
Surface mounting, more suitable for deep, fast-flowing rivers or tidal sites so the turbine is higher in the water column giving a high flow speed and therefore generating more power
A second row of turbines can be added if the barge is large enough, thus further increasing power output
