Tidal Generation Limited - Capturing energy in deep water

Our Technology

Tidal Generation Limited (TGL) is developing a 1MW fully submerged tidal turbine. We have developed innovative concepts for the installation and maintenance of our machine in deep water. Our turbine.....

exploits the resource in depths > 30m
minimises visual and shipping impacts
is cheap to construct and easy to install due to the lightweight (80 tonnes/MW) support structure (ie 7.7 KW/te)
uses readily available vessels for maintenance
allows rapid removal and replacement of powertrains, enabling safe maintenance in a dry environment
employs simple, passive systems wherever possible
is located out of the wave zone for improved survivability

On the basis of comprehensive techno-economic modeling, we believe our device will generate electricity costing 8-9p/kWh for initial farms, falling to 5-6p when the technology is sufficiently well established for projects to attract competitive interest rates. This is at the lower limit of estimated costs quoted by a recent carbon trust report (Future Marine Energy) using the same basis of calculation, which gave central estimates in the range 12p to 15p kWh.
