TIDAL CURRENT ENERGY
Northeast Normal University (NNU): NNU turbine (15 kW) is a H-axis turbine, with cut-in speed of 0.45 m/s. The NNU turbine has been deployed near Zhaitang Island for open sea test since May 2016. The maximum output power is 15 kW, and the conversion efficiency is 25%. In 2016, CSSC Electronics Technology Co. Ltd and NNU were funded RMB 10 million by SFPMRE to develop the power system for ocean observation equipment based on NNU turbine.
Institute of Electrical Engineering (IEE) of the Chinese Academy of Sciences (CAS): IEE turbine (2×2.5 kW) is a floating H-axis turbine installed on the platform. The platform is 36m × 8m × 2m. The device was deployed near Xisan Island for open sea test in July 2016. During the test, the maximum output power is 1.73 kW, and the conversion efficiency is 40%.
WAVE ENERGY
Guangzhou Institute of Energy Conversion (GIEC) of the Chinese Academy of Sciences (CAS): In November 2015, the 100 kW prototype of Sharp Eagle Wanshan was deployed for testing in Wanshan Islands. The device is 36m × 24m × 16m. Different from the single floating buoy of Sharp Eagle I, the 100 kW Sharp Eagle is installed with four floating buoys, which are placed with two buoys on each side symmetrically. As verified by the test result, the wavelet is available to be absorbed and the good performance on wave energy absorption is proven. During testing time, when the wave period between 4~6.5 seconds and the wave height range of 0.6~1.8 meters, most of the data remain above 20%, with the highest efficiency reaching 37.7%. The amount of electricity generated accumulated more than 30 MWh till June 2016.

The Institute of Electrical Engineering (IEE) of the Chinese Academy of Sciences (CAS): Supported by the SFPMRE, the IEE invented a novel point-absorber wave energy converter (10 kW) based on magnetohydrodynamic generators. The device was deployed for open sea testing near the Wanshan Islands. The total efficiency of the device is about 17.8%. The project passed the SOA inspection in July 2016.
OTEC
Supported by SFPMRE, the First Institute of Oceanography (FIO) of the SOA is developing an OTEC device using non-azeotropic ammonia-water mixture since 2013. The FIO has completed the design and installation of the OTEC system in 2016. The device achieves the power of 10 kW with its total efficiency over 3%. The FIO will carry out testing operation to verify the reliability of the OTEC system in 2017.
