The development of offshore wind farms has experienced rapid growth during the past decade. In particular, China has the highest number of installations worldwide, but some challenges exist for further development. Consequently, some researchers suggest combining wave energy with offshore wind energy. To fully implement this plan, a comprehensive resource assessment of combined offshore wind and wave energy systems is needed. Investigations of the parameters, such as the spatial and temporal distribution of wind and wave energy, aggregate resource reserves, available technical potential, and total capacity factor, are vital for designing the required wind turbines and wave energy converters. To assist scientific development and governmental decision making, this paper aims to evaluate offshore wind and wave energy resources from a technological perspective. The results show that theoretical offshore wind and wave energy resources are abundant in China's ocean territory, with a potential of approximately 3 TW. Technically, of the three most popular offshore wind turbines, i.e., 6, 8, and 10 MW, 10 MW is overall the most suitable in China. However, of the three wave energy converters, i.e., 120, 250, and 750 kW, 120 kW is the best candidate for Liaoning Province, and 750 kW is the most suitable for the remainder of its region. Overall, the total annual energy production is approximately 7000 TWh.

引用

Journal of Mountain Science 2018年第3期15卷 645-656页

作者： WANG Lei LIU Jia-ming WANG Ling-en ZHU He LIN Jing Institute of Geographic Sciences and Natural resources Research Chinese Academy of Sciences Beijing 100101 China College of Humanities Ningxia University Yinchuan 750021 China Key Laboratory of Regional Sustainable Development Modeling Chinese Academy of Sciences Beijing 100101 China University of Chinese Academy of Sciences Beijing 100049 China

The reasonable development and utilization of mountainous regions closely relates to local economic development and ecological security. The wine production region in the eastern foothills of the Helan Mountains in Ningxia, Ningxia Hui Autonomous Region, with its excellent terroir, is emerging as one of China's three major geographical attractions. Based on surveys of tourism resources and spatial analysis for this wine producing region, we propose a highly representative and practicable path for wine tourism development. Based on China's national standard in Classification, Investigation and Evaluation of Tourism resources(GB/T 18972-2003), which recommended the types and grades of tourism resources in one area, we conduct an analysis of resource characteristics and the current state of development. Using Arc GIS software, spatialautocorrelation analysis, average nearest neighbor analysis, as well as clustering and outlier analysis, we are able to derive the spatial distribution characteristics of tourism resources. Our survey showed that tourism resources in this area are relatively abundant and have good quality and clear combination advantages. Nonetheless, there are resources shortage for wine tourism and poor integration of wine production with the tourism industry. Regarding the spatial distribution of resources, we revealed the current states of and issues surrounding regions with concentrated resources, as well as characteristics of this clustering. Finally, we proposed a development path for wine tourism in this region based on the five dimensions of management mode, industrial path, product development, spatial optimization, and market development.

Petroleum resource assessment of the East Greenland Basin

引用

Advances in Polar Science 2017年第4期28卷 297-310页

作者： LI Bin LIU Chenglin ZHAO Yue HONG Weiyu PING Yingqi LIANG Dexiu State Key Laboratory of Petroleum resource and Prospecting China University of Petroleum College of Geosciences China University of Petroleum Institute of Geomechanics Chinese Academy of Geological Sciences

The onshore and offshore parts of the East Greenland Basin are important areas for petroleum exploration at the North Pole. Although assessments by the US Geological Survey suggest a substantial petroleum potential in this area, their estimates carry a high risk because of uncertainties in the exploration data. This paper compares the reservoir-forming conditions based on data from the East Greenland Basin and the North Sea Basin. The petroleum resources of the East Greenland Basin were assessed by geochemical and analogy methods. The East Greenland Basin was a rift basin in the late Paleozoic–Mesozoic. Its basement is metamorphic rock formed by the Caledonian Orogeny in the Archean to Late Ordovician. In the basin, Devonian–Paleogene strata were deposited on the basement. Lacustrine source rock formed in the late Paleozoic and marine source rocks in the Late Jurassic. Shallow-marine sandstone reservoirs formed in the Middle Jurassic and deep-marine turbiditic sandstone reservoirs formed in the Cretaceous.The trap types are structure traps, horst and fault-block traps, salt structure traps, and stratigraphic traps. The East Greenland Basin possesses superior reservoir-forming conditions, favorable petroleum potential and preferable exploration prospects. Because of the lack of exploration data, further evaluation of the favorable types of traps, essential amount of source rock, petroleum-generation conditions and appropriate burial histories in the East Greenland Basin are required.

Journal of Energy and Power Engineering 2015年第4期9卷 358-366页

作者： Chul Hee Jo Su Jin Hwang Kang Hee Lee Department of Naval Architecture and Ocean Engineering Inha University Incheon 402-751 South Korea

After the nuclear power plant accident in Japan, Korean government has set the national goal to produce the electricity by renewable energy sources up to 11% by 2035 which is not easy to achieve without ocean energy development. The demand on the clean energy supply has been increased recently and there are many renewable energy development projects and plans announced worldwide. The ocean energy can be produced from tidal current, wave, tidal barrage and ocean thermal sources. The first step is to estimate the resource assessment for each energy source. There are several assessment methods introduced from IEA （International Energy Agency）, IRENA （International Renewable Energy Agency）, NREL （National Renewable Energy Laboratory）, EU ERENE （European Community for Renewable Energy）, Bonn University, DLR （German Aerospace Center）, etc.. Even these known methods have some sort of similarity; there are different definitions and classifications among them. In this paper, the four-step energy potentials are defined and introduced as theoretical, geographical, technical and market potentials. The theories for each step are presented for ocean energies together with clear definitions. As the tidal current energy research and development are active in Korea having very strong tidal current speed along the west and south coastal regions, the detail procedure for each step of energy potential assessment is introduced for tidal current energy. The paper will illustrate the case study of tidal current power assessment in western coastal region, South Korea with highlighting the key aspects in determining the resource potentials.

China Ocean Engineering 2020年第1期34卷 137-150页

作者： Chul Hee JO Su Jin HWANG Department of Naval Architecture and Ocean Engineering Inha University

Tidal current power is one of the promising and reliable renewable energies with the advantage of continuous and predictable resource. It can make stable electricity regardless of weather conditions or seasons all year around. The required technologies for tidal current power in the ocean have been developed for years and now recognized that it could be commercialized after intensive field tests and successful demonstrations. There are several tidal farm development projects in the world, such as the MeyGen project in UK with its commercialization at hand. However, various research subjects in the tidal current energy field are seeking improvements and industrialization of tidal current power in terms of economy and technical reliability. This paper introduces the resource assessment procedure of tidal energy that has been applied in Korea coastal regions. The key research subjects for tidal current power together with the interaction effect of multi-arrangement is described. Also, this paper is to introduce the research output of each subject such as turbine design, experimental validation, turbine interaction and wake, multi-array module, FSI (fluid-structure interaction), and duct application.

Estimation of potential distribution of gas hydrate in the northern South China Sea

引用

Chinese Journal of Oceanology and Limnology 2010年第3期28卷 693-699页

作者：王春娟杜德文朱志伟刘永刚闫仕娟杨刚 The First Institute of Oceanography State Oceanic Administration Key Lab of Marine Sedimentology & Environmental Geology of State Oceanic Administration The College of Marine Geosciences Ocean University of China

Gas hydrate research has significant importance for securing world energy resources, and has the potential to produce considerable economic benefits. Previous studies have shown that the South China Sea is an area that harbors gas hydrates. However, there is a lack of systematic investigations and understanding on the distribution of gas hydrate throughout the region. In this paper, we applied mineral resource quantitative assessment techniques to forecast and estimate the potential distribution of gas hydrate resources in the northern South China Sea. However, current hydrate samples from the South China Sea are too few to produce models of occurrences. Thus, according to similarity and contrast principles of mineral outputs, we can use a similar hydrate-mining environment with sufficient gas hydrate data as a testing ground for modeling northern South China Sea gas hydrate conditions. We selected the Gulf of Mexico, which has extensively studied gas hydrates, to develop predictive models of gas hydrate distributions, and to test errors in the model. Then, we compared the existing northern South China Sea hydrate-mining data with the Gulf of Mexico characteristics, and collated the relevant data into the model. Subsequently, we applied the model to the northern South China Sea to obtain the potential gas hydrate distribution of the area, and to identify significant exploration targets. Finally, we evaluated the reliability of the predicted results. The south seabed area of Taiwan Bank is recommended as a priority exploration target. The Zhujiang Mouth, Southeast Hainan, and Southwest Taiwan Basins, including the South Bijia Basin, also are recommended as exploration target areas. In addition, the method in this paper can provide a useful predictive approach for gas hydrate resource assessment, which gives a scientific basis for construction and implementation of long-term planning for gas hydrate exploration and general exploitation of the seabed of China.

Energy Engineering 2021年第4期118卷 1111-1133页

作者： Sakarias Paaso Ali Khosravi Department of Mechanical Engineering Aalto UniversityEspooFinland

Potential revenue from wind power generation is an important factor to be considered when planning a wind power *** the future,that may become even more important because it is known that wind power generation tends to push electricity wholesale prices ***,it is possible that if a region has plenty of installed wind power capacity,revenue per generated unit of electricity is lower there than could be assumed by looking at the mean electricity wholesale *** this paper,we compare 17 different locations in Finland in terms of revenue from wind power *** is done by simulating hourly generation with three different turbine types at two different hub heights and multiplying that by the hourly electricity spot price for years 2018 and *** revenues differ greatly between locations and turbine types,major factor being technical potential i.e.,the amount of electricity *** between revenues per generated MWh seem to be small,however,the smallest figures being on the western coast where installed capacities are also the largest in Finland.
