我国海岸线长、海域辽阔,海洋能的蕴藏量相当丰富。已知海洋开发成为国家战略的一部分,海洋可再生能源的开发利用也得到相当程度的重视。海洋可再生能源开发利用的科学技术和产业发展都需要大量的专业人才。作为一个新兴的可再生能源利用领域,如何吸引、培养数量质量足够的人才就显得非常紧迫。但是,目前我国海洋可再生能源领域人才政策缺失。为了促进我国海洋能的发展,完善海洋能政策体系,文章针对海洋能领域的人才政策,从人才设置、人才培养机制、人才保障、人才激励4个方面分别展开分析,并给出了建议。 相似文献

随着国际社会对海洋可再生能源开发利用的关注,众多海洋能发电装置投入研发。目前我国已有相当一部分海洋能发电装置进入海试阶段。因此,在海洋能发电装置海试的过程中,需要对海洋能发电装置的发电性能进行检测。文中介绍了海洋能发电装置现场检测平台的设计,研究并设计检测方法以满足海洋能发电装置现场检测的需求。海洋能发电装置现场检测平台的设计以满足波浪能、潮流能发电装置的测试需求为主,兼顾其他形式的发电装置。该平台主要对海洋能发电装置的功率特性、电能质量特性以及电网适应性等指标进行测试,并根据海洋能发电装置的测试结果开展分析与评价。 相似文献

Competing usage of marine space has prompted several coastal nations to implement marine spatial planning (MSP). While progressive governments promote the deployment of renewable energy technologies (RETs) in order to meet renewable energy capacity and greenhouse gas emissions reductions targets, offshore RETs become another player operating within a finite and already stressed marine environment. This paper applies the sectoral MSP process employed by Scotland to the Nova Scotia context in order to draft a MSP for the province's tidal energy sector. Applicable legislation is reviewed in order to establish the regulatory authorities with powers to plan for both the marine development and ecosystem protection agendas. The scoping process identifies suitable resource areas based on the operational parameters of commercially viable tidal current turbines (TCTs), while the sustainability appraisal identifies areas of cultural, industry, ecological, and socioeconomic constraint and exclusion. Plan option areas emanating from the applied methodology demonstrated a 238.345 km2 (98.1%) increase in suitable TCT deployment area than the marine renewable energy areas identified in Nova Scotia's Marine Renewable Energy Act which did not undertake such a methodology. 相似文献

Many countries now recognise the need for mitigation of climate change induced by human activities and have incorporated renewable energy resources within their energy policy. There are extensive resources of renewable energy within the marine environment and increasing interest in extracting energy from locations with either large tidal range, rapid flow with and without wave interaction, or large wave resources. However, the ecological implications of altering the hydrodynamics of the marine environment are poorly understood. Ecological data for areas targeted for marine renewable developments are often limited, not least because of the considerable challenges to sampling in high energy environments. In order to predict the scale and nature of ecological implications there is a need for greater understanding of the distribution and extent of the renewable energy resource and in turn, of how marine renewable energy installations (MREIs) may alter energy in the environment. Regional ecological implications of a MREI need to be considered against the greater and global ecological threat of climate change. Finally, it is recommended that the identification of species and biotopes susceptible to the removal of hydrokinetic energy could be a suitable strategy for understanding how a MREI may alter flow conditions. 相似文献

Renewable energy from the ocean 总被引：3，自引：0，他引：3
Growing concern over the threat of global climate change has led to an increased interest in research and development of renewable energy technologies. The ocean provides a vast source of potential energy resources, and as renewable energy technology develops, investment in ocean energy is likely to grow. Research in ocean thermal energy conversion, wave energy, tidal energy, and offshore wind energy has led to promising technologies and in some cases, commercial deployment. These sources have the potential to help alleviate the global climate change threat, but the ocean environment should be protected while these technologies are developed. Renewable energy sources from the ocean may be exploited without harming the marine environment if projects are sited and scaled appropriately and environmental guidelines are followed. 相似文献

基于逐年30 m分辨率的岸滩遥感监测数据集(1986—2017年),开展舟山群岛不同主体功能海岛岸滩的时空演化特征分析。结果表明,在1986—2017年期间,受剧烈围填海活动的影响,舟山群岛的大量水域(152 km2)和潮滩(18 km2)被围填成陆地,岸滩不断向海推进,政策是岸滩总体变化的主要驱动因素。不同海岛主体功能类型的岸滩变化特征差异显著：(1)综合利用岛、临港工业岛、港口物流岛、滨海旅游岛的围填海占研究区围填海总量的96%;(2)海洋科教岛和现代渔业岛的岸滩变化幅度较小,占研究区围填海总量的4%;(3)海洋生态岛和清洁能源岛的岸滩资源保育良好,稳定不变。 相似文献

Marine renewable energy is seen as an important component of the UK's future energy strategy and contribution to reducing the greenhouse gas emissions responsible for climate change. The UK aims to generate a total of 33 GW (gigawatts) of offshore wind energy. Its implementation strategy includes the development of ten offshore wind farms within Scottish territorial waters. In addition, between 1000 MW (megawatts) and 2600 MW of marine renewable energy generating capacity could be achieved in Scotland using wave and tidal power devices. However, there are negative environmental impacts associated with marine renewable energy. Intense noise is produced during pile driving, drilling and dredging operations with potential consequences for cetaceans. There are also increases in vessel activities during exploration, maintenance and construction with association risks of disturbance and collisions. Some underwater devices will be large and may be positioned in arrays across the habitats that cetaceans frequent. The consequences of encounters between cetaceans and such devices are as yet unknown. It is recommended that the Scottish Government complete full and transparent Marine Spatial Planning, including consideration of cumulative impacts, before moving to license appropriate sites. 相似文献
