基于能值分析的中国潮汐能发电可持续性研究——以浙江省江厦潮汐试验电站为例
Emergy-based analysis of sustainability of tidal power plant in China: A case study of the Jiangxia tidal power
摘要
Abstract
Although endowed with abundant tidal resource,China's tidal power generation industry has been largely lagging compared with other renewable energy alternatives such as small hydropower,photovoltaic power,wind power and biomass power.To probe the reasons behind this stagnancy,an emergy evaluation was conducted for the 4.1 MW Jiangxia Tidal Power Station (JTPS),the largest tidal power station in China and the fourth in the world.The evaluation results indicate that the total emergy use of this production system was 5.08× 1019 sej to generate 2.61×1013 J of electricity in 2014,of which renewable resources accounted for 17.77％.Thus,the transformity of electricity produced by this plant is 1.95 × 106 sej · J-1.The environmental loading ratio (ELR) and the emergy sustainability index (ESI) of the JTPS were 4.63 and 0.12 respectively,exhibiting a poorer environmental performance than other renewable energy power plants except photovoltaic power.These results reveal that tidal energy is a kind of lower quality and more decentralized energy and its current exploitation presents low environmental competitiveness.In such context,the development of tidal power in China should proceed with cautions and avoid large-scale blind development.Nevertheless,R&D is needed to promote the technology development and ultimately utilize abundant tidal resource in an efficient and sustainable way.关键词
