TorqTidal seeks to provide control strategies for tidal current turbines that will reduce the risk of failure and increase the lifetime of device components without increasing capital costs. This will act to increase investor confidence and drive down the LCOE, which is a key step in helping the UK to exploit its significant tidal energy resource.
WindSurf aims to develop a core enabling technology - active blade pitching for a vertical axis wind turbine. This will allow wind turbines to operate in challenging wind conditions, to operate quietly and for new, lower maintenance turbine designs. WindSurf will open up new sites for wind energy: sites previously rejected because wind speeds were too low, variable or subject to swirling, or where noise nuisance would have been a concern. WindSurf will tackle all three parts of the energy trilemma: reducing emissions, increasing security of supply, and reducing cost.
Marine energy should make a substantial contribution to the UK renewable energy target of 30% electricity by 2020. Tidal stream turbines are a more mature technology than wave energy devices while the potential of wave energy is considerable. There is a growing capability and confidence in the loading and performance of marine energy devices in operating conditions as designs rapidly develop. However knowledge of extreme loading is less mature and indeed there is some uncertainty about their origin.
