Compared to other renewable sources of energy, tidal energy is highly predictable. Tidal stream turbines are likely to prove more cost-effective, and have minimal impact on the local marine biodiversity compared to the tidal ranges (or dams). However, the levelized cost of energy (LCOE) from tidal stream turbines is far higher compared to the grid average, and needs to be brought down significantly to make energy generation from tidal turbines an economically viable option.
The main objective of the TIPA (Tidal turbine Power take-off Accelerator) project, led by Nova Innovation Limited, is to design and demonstrate a next-generation cost-effective and reliable power take-off (PTO) system for tidal stream turbines. In addition to Nova Innovation and TU Delft, other partners include University of Edinburgh, RWTH Aachen University, Siemens, SKF and Wood Group.
The aim is to reduce the LCOE of tidal power by 20% compared to present market values. The three main strategies to achieve this are: 

  • By improving performance and efficiency over the existing conventional PTO by using a direct drive generator, eliminating losses due to a gearbox.
  • By improving the reliability of the system so that the service and maintenance interval is increased beyond 2 years.
  • By ensuring that the device has an expected lifetime of >20 years by subjecting it to accelerated lifetime testing prior to deployment.

In this talk, Faisal Wani shall briefly present the state-of-the-art in the tidal turbine industry, and the current challenges faced by the tidal turbine manufacturers in their efforts to economically exploit tidal energy. The focus of the talk shall be to present the recent trends adopted in the industry to increase the efficiency, reliability and survivability of the tidal PTO systems. Faisal Wani is currently pursuing his PhD in Electrical Sustainable Energy Department at the Faculty of Electrical Engineering, Mathematics and Computer Science, TU Delft. His supervisors are Dr. ir. H. Polinder and Prof. dr. J. A. Ferreira.
