2 Outline Brief introduction to SOA and NOTC Ocean energy policy of China Status of Research and Development Status t of Technology Demonstrations ti Furture priorities

3 Brief introduction to SOA and NOTC

4 Introduction to SOA The main functions of State Oceanic Administration (SOA) is to take the implementation of maritime legislation, planning and management, is responsible for overall coordination of ocean affairs. In 2008,the State Council mandated the responsibilities Research, Application and Management of Marine Energy to SOA. The Main tasks of SOA: Survey of marine energy resources Formulation of the policies and standards for marine energy Organization of technology Research, Development and Demonstration for marine energy.

5 Introduction to NOTC NOTC is under the leadership of SOA. The main duties of NOTC are to take management for ocean technology (including ocean energy), and provide technical support for national ocean operational system. NOTC is the earliest institute in China which engages in marine energy research and development. NOTC has established a professional marine energy laboratory and a branch of the Commission of China Ocean Standard for making marine energy standards.

6 Introduction to NOTC Since 1985, NOTC has completed Xiaoheishan wind desalination project, Xiaomai island "8 kw Pendulum-type Wave Test Power Plant project and Daguan Island "30 kw Pendulum-type Wave Power Plant Demonstration projects. Daguan island 30 Kilowatts Pendulum-type Wave Power Plant in DAGUAN Island Wave and Current Flume

7 Introduction to NOTC The main tasks of NOTC for ocean energy Undertake the survey and assessment of marine energy resources of China Draft the policies and strategies for marine energy Draft the standards of marine energy Take charge of building and operating of ocean energy sea test site Engage in technology research and development of marine energy, especially focusing on wave energy conversion.

8 Ocean energy policy in China

9 Law and special plan The Renewable Energy Law, revised amendment in Dec. 2009, has raised a special grant for renewable energy, including marine energy. SOA will draw up the ocean energy development special plan, and incentive policy for promoting the utilization of marine energy.

10 Relative Plans A lot of national plans and strategies including the tasks in development and utilization of marine energy: Mid-Long term Development Plan for Renewable Energy National Program for Mid-Long Term S&T Development ( ) National marine development plan ( ) National program to boost marine industry through S&T advances ( )

11 Supportive programs Key Technologies R&D Program, MOST - 60M for OES High-tech R&D Program (863 Program), MOST - 10M.. Ocean Public Benefit Research Project, SOA - 10M.. Ocean survey and evaluation project, SOA - 24M.. Knowledge Innovation Program, CAS - 5M 5M.. In addition,soa is actively working to establish a special fund for the development of marine energy.

12 Status of Research and Development

13 Status of R&D of Tidal Energy 1 tidal power plant has been operating for 30years. 2 tidal power plants have been proposed. Site Name Location Jiangxia Jiantiaogang (Proposed) Bachimen (Proposed) Wenling Samen Fuding Zhejiang Zhejiang Fujian Installed/Design Capacity(MW) Mean Tides Range(m) ( ) Area of Reservoir(km^2) Effective Volume(m^3) Starting Time Tidal Power Plant in China

14 Status of R&D of Tidal Energy New research focusing on: New type tidal turbine for 10MW tidal power plant Design, construction, transportation and location technologies of the caisson Underwater installation foundation Environment impact assessment

15 Status of R&D of Wave Energy A number kinds of wave energy conversion devices have been developed Since 1980s. Type Installed Capacity PTO (To be) Completed (kw) Year OWC 3kW/10kW/100kW Air Turbine BBDB 5kW Air Turbine 1996 Pendulum 8kW/30kW Hydraulic 1995/2000 Oscillating Buoy 50kW Hydraulic 2006 Floating Duck 100kW Hydraulic 2011 Offshore Surging Swing 100kW Hydraulic 2011

16 Status of R&D of Wave Energy 5kW backward bent duct buoy 100kW OWC wave device 50kW oscillating buoy device Hydraulic PTO system 30 KW Pendulumtype wave device

17 Status of R&D of Wave Energy 0.3kW sea trial model of 100kW floating wave power devices (Guangzhou Institute of Energy Conversion, CAS ) Model of 100kW surging-swing wave power device in lab. (NOTC,SOA) 100 KW surging- g swing wave device

18 Status of R&D of Tidal Current Energy Vertical and Horizontal axis tidal current energy conversion devices have been developed since 1980s. Type Installed Capacity (kw) Features (To be) Completed Year 70kW floating 2002 Vertical 40kW bottommounted KW 2 floating kW low-velocity turbine 2005 Horizontal 5kW Flexible blade kW ssurface self-adaptive KW 22 self-adaptive 2011

19 Status of R&D of Tidal Current Energy Vertical axis technology ---Harbin Engineering University 70kW Wanxiang- I floating plant 40kW Wanxiang-II bottom-mounted mounted plant

20 Status of R&D of Tidal Current Energy 2kW model of 20kW marine current power devices Concept design of 150kW tidal stream power system 1kW current turbine for underwater devices power supply Flexible blade power plant design

21 Challenges Chinese marine energy resource has the features shown as below: low density of energy much more storms and typhoons tough environment for survivability, etc. So, we need to develop special technologies to fit the features of Chinese marine energy harnessing. We are willing to cooperate with the developed countries to improve the technical level of China.

22 Status of Technology Demonstrations

23 Ongoing Demonstrations 2 isolated hybrid power demonstration systems are under construction; 1 tidal current demonstration project cooperating with Irish Company (OpenHydro Group Ltd.) has been initiated by China Energy Conservation Investment Corporation; Sea test site project for marine energy technology demonstration has been proposed.

24 Isolated hybrid power demonstration system in Daguan island, Shandong Province Components: 30kW swing wave power generation system 60kW Wind Turbines 10kW solar power system Desalination System (5 tons/d) Solar power system Wind Turbine Wave Conversion Device Desalination Device

25 Isolated hybrid power demonstration ti system in Dangan island, Guangdong Province Components: 10kW floating wave power device 90kW Wind Turbines 5kW solar power system Desalination System 10kW floating duck-type wave power device

26 Cooperation with OpenHydro Group Ltd. China Energy Conservation Investment Corporation has signed a cooperation agreement with OpenHydro Group Ltd. Apr Plan to build a 1MW tidal current power demonstration system in Zhejiang Province. OpenHydro tidal current turbine

27 Future priorities More and more national plans and programs will support marine energy research, development and demonstration in China. China has come into a new stage of development and utilization of marine energy on a large scale. NOTC would like to introduce advanced international marine energy technologies and promote China's technological progress through the localization.
