Easily scalable and with minimal ecological impact, VETT is designed for low-head hydro settings of 4m and below. Depending on the setting and flow rate, we have the following solutions:

STANDARD VETT

For flow rates from 2,000 l/s 

For run-of-river hydro project with a flow rate larger than 1,500 l/s.

VETT-in-a-BOX

For flow rates from 500 l/s

A compact, easy to install design. Patents are still being assessed, hence we can't show any images yet.

TIDAL VETT
 

For tidal range projects

For use in tidal estuaries or lagoons, bi-directional as well as uni-directional for ebb or flow mode only.

STANDARD VETT

The Standard VETT is VerdErg's original hydropower solution. It can be installed in an open concrete tank for systems above 30 kW to 1MW+.

 

It targets run-of-river projects but can be placed in any low-pressure water course, such as waste water outfalls or water treatment plants.

 

Each system is individually scalable to cover installed capacities from 20 to 180kW and multiple units are installed in parallel to cover larger projects. The system can be grid connected, power mini grids or used off-grid.

VETT-IN-A-BOX

VETT-in-a-Box brings electricity to the most remote, off-grid locations worldwide and has the potential to replace hundreds of diesel-powered generators.

 

It is a 'plug & play' solution that arranges an entire mini system in a portable, easy to install, container-based arrangement that is manufactured off-site. This includes a 2-30 kW power cabinet for direct electricity consumption or connection to a local mini grid. It is installable in a stretch of flowing water using flow rates from ca. 500 l/s and a head drop of only 2m, integrated directly into or adjacent to a water course.

 

It is ideal for smaller or remote run-of-river projects, as well as waste water outfalls or pressure reduction points. Temporary setup only is also feasible, making it suitable for disaster relief responses.

The design is still in development and so are the patents, hence we can't show any images here.

 
TIDAL VETT

Tidal VETT is a patented bi directional VETT uniquely suitable for power generation from tidal flows such as estuaries and tidal channels because of its benign environmental footprint and competitive capital cost.

 

Due to its ability to cost effectively extract energy from low-head flows a VETT system is substantially different to a conventional tidal installation (like a barrage or lagoon).

Conventional tidal schemes require to install infrastructure that can exploit, over a short period of time, the maximum tidal range present in a given location (often 8m and above, especially in the UK).

 

Due to its ability to amplify a low head for a turbine, a VETT tidal scheme does not require infrastructure of that magnitude.

It is rather designed to exploit a lower head over a longer period of time, which preserves the tidal signal in the landwards lagoon and impacts on flora and fauna are minimised. And safe fish passage through the primary flow remains available as well.

Despite estuaries being identified as a key source of tidal energy within Europe, North America and Asia no recent conventional tidal schemes have gained approval because of cost as well as environmental deficiencies. 

 

VerdErg has set out to change that and is continuing it's effort for a tidal VETT prototype installation and is thankful for the keen support of various regulators and interest groups, especially Wyre Tidal Energy and Solway Energy Gateway.
