中国LNG接收站建设与未来发展

LNG TERMINAL CONSTRUCTION AND FUTURE DEVELOPMENT IN CHINA

至2018年底,煤炭在我国一次能源消费中的比例约为58%。大量的煤炭作为一次能源势必导致大气污染。提高能效、增加非化石能源和天然气的消费比重是国家改变能源消费结构的长期目标和策略。见效快、易于实现的大气改善途径之一,是提高一次能源消费中天然气的比重。2018年天然气表观消费量达到了2 803亿m^3,进口天然气750亿m^3,对外依存度45%。根据国家能源策略预测,2030年以前LNG进口量仍有较大增长,到2030年接收站接卸能力将达到2.35亿t/a。综合论述了中国LNG接收站建设与未来发展以及国产化过程中存在的问题,并对中国LNG需求给出了预测。

By the end of 2018,coal accounted for about 58%of primary energy consumption in China and a large amount of coal as a primary energy source is bound to cause air pollution.Improving energy efficiency and increasing the proportion of non-fossil energy and natural gas consumption are the country’s long-term goals and strategies to change the energy consumption structure.One of the ways to improve the atmosphere quickly and easily is to increase the proportion of natural gas in primary energy consumption.In 2018,China’s apparent consumption of natural gas reached 280.3 billion cubic meters,and the imported natural gas reached 75 billion cubic meters,which was 45%dependent on foreign energy sources.According to the prediction of the national energy strategy,LNG imports will continue to grow significantly before 2030,and the receiving and unloading capacity of the terminals will reach 235 million t/a by 2030.This paper comprehensively discusses the problems in the construction and future development of China’s LNG terminals and the localization process,and forecasts China’s LNG demand.
