RESEARCH & DEVELOPMENT

WAVE ENERGY
 

• Sharp Eagle WEC
  In 2015, the Guangzhou Institute of Energy Conversion (GIEC) successfully developed and built the 100kW prototype of Sharp Eagle “Wanshan”. The device is 36m×24m×16m, and weighs 1,000 tons. It’s a floating power station. The device was deployed near Wanshan Islands for sea trial in November 2015. The device realized intermittent power generation in small waves of 0.5 meters and safe power generation in large waves of 4 meters, and the total conversion efficiency reached above 20%. In April 2017, Sharp Eagle “Wanshan” was connected to the grid on Wanshan Island.
  
  In December 2017, supported by the Chinese Academy of Sciences (CAS) and China Southern Power Grid, the upgrade of 260 kW wave-solar-storage-desalination offshore floating energy platform "Pilot 1" based on Sharp Eagle technology was completed (Installed wave energy 200 kW, Installed solar energy 60 kW, a desalination facility with daily production of 6 tones water). 
  
  The 260 kW "Pilot 1" offshore floating energy platform deployed for open sea test in January 2018 and was successfully connected to the remote island power grid through submarine cables in Hainan province on 31 August 2018. 
  
  
   
• Power Platform for Offshore Cage
  In order to solve the situation of shortage of energy supply and poor wind-wave resistance of traditional aquaculture cages in China, the GIEC combines Sharp Eagle wave power generation technology with aquaculture, offshore tourism, science popularization, using wave energy to power the integrated platform of aquaculture, tourism, science popularization. The GIEC has applied patents for the integrated platform technology for aquaculture powered by wave energy and tourism in China, the European Union, Japan and Canada. Construction of the first prototype began in December 2018, and it is expected to be completed in June 2019. 
   

TIDAL CURRENT ENERGY

• ZJU 650 kW H-axis Turbine
  Sponsored by SFPMRE and the MOST, the Zhejiang University invented a series of tidal current energy turbines.
  
  The 60 kW tidal current energy turbine was deployed in 2014. The 120 kW semi-direct drive H-axis turbine was deployed in 2015. And the Zhejiang University deployed a 600 kW horizontal axis turbine in 2018.
  
  This is the third turbine, after the 60 kW and 120 kW sea trials, cut in current velocity: 0.7 m/s, rated current velocity: 2.5 m/s.
  
  
  United Power 300 kW H-axis Turbine
  Sponsored by SFPMRE, the Guodian United Power Technology Company Limited (United Power) is developing a new 300 kW H-axis turbine.
  
  The turbine has been deployed near Zhairuoshan Island for sea trial and connected to the grid since March 2018, generating 288 MWh until November 2018.
  
  Cut in current speed: 0.5m/s, Rated current speed: 2.0 m/s, Maximum conversion efficiency: 40%, Support structure: Floating.
