Tidal range energy

Hydro China Huadong Engineering Corporation: The cooperated project for dynamic tidal power (DTP) was listed as one of the energy development cooperated projects between China and Netherlands in May 2014.

After preliminary investigation and site selection by Huadong Engineering Corporation, Dongshan Island in Fujian Province was selected as one of the best sites for DTP utilization.

Tidal current energy

Zhejiang University (ZJU): ZJU turbine (60 kW) is a semidirect drive floating horizontal axis turbine, which was co-sponsored by the 1st round of SFPMRE and National Hightech R&D Programme (863 Programme). The ZJU turbine was deployed near Zhairuoshan Island for sea trial in May 2014.

During the sea trial, the maximum output power has reached 31.5 kW and the conversion efficiency is 0.371. Now, Guodian United Power Technology Co. has initiated the development of a new 300 kW turbine based on ZJU turbine. 

Harbin Engineering University (HEU): Haineng I (2×150 kW) floating vertical axis turbine with 0.8m/s of cut-in speed, cosponsored by 863 Programme and National Key Technology R&D Programme, has been suspended after several months of sea trial for mechanical failure (the one on the right in the figure below). Haineng III (2×300 kW) floating vertical axis turbine with 1.2m/s of cut-in speed, was supported by the 1st round of SFPMRE. Haineng III (the one on the left in the figure below) has been deployed for sea trial in Guishan Channel since December 2013 and hit by several typhoons, with total conversion efficiency of 30%.

Zhejiang Zhoushan LHD New Energy Corporation Limited (LHD): LHD L-1000 (4×300 kW) turbine project obtained RMB 19 million support from the 4th round of SFPMRE in 2013. The project completed the site selection and obtained the consent of local government in July 2014. The infrastructure and the design of the turbine were completed. 

Wave energy

Guangzhou Institute of Energy Conversion (GIEC) of Chinese Academy of Sciences (CAS): Sharp Eagle I (10 kW) floating wave energy converter was firstly deployed for test in December 2012, and redeployed near Wanshan Island in July 2013 after maintenance. By 30th April 2014, Sharp Eagle I had been running for nearly 6000 hours accumulatively, with total conversion efficiency of 16.76%. With the support of the 4th round of SFPMRE in 2013, GIEC and China Shipping Industry Co. are jointly developing 100 kW device based on Sharp Eagle I.

Jimei University (JMU): Jida I (10 kW) floating wave energy converter sponsored by the 1st round of SFPMRE in 2011, was deployed near Xiaodeng Island for sea trial in May 2014.

The average output power was about 600W under the wave height of 0.3 m, the maximum instantaneous output power is 1.56 kW.

China Shipbuilding Industry Corporation 710 Institute (CSIC 710): Hailong I (150 kW) converter, suspended sea trial for maintenance after 2 months of test in September 2014.

NOTC: FLB (2×50 kW) bottom-mounted flap-type converter was firstly deployed in June 2012 and endured the hits of typhoon, validating good reliability, with total conversion efficiency of 14% With the support of the 4th round of SFPMRE, NOTC and Qingdao Haina Heavy Industry Co. are optimizing a new 50kW converter.
