海流能是指蕴涵于海水流动中的能量,具有能量密度大、出力稳定等特点。据估计,世界各大洋中所有海流的总功率达50亿千瓦左右,是海洋能中蕴藏量最大的一种。目前,世界上从事海流能开发的国家主要有美国、英国、加拿大、日本、意大利和中国等,其中英国的海流能发电已进入商业化运 Current can be implied in the sea water flow energy, with energy density, output stability and so on. It is estimated that the total power of all ocean currents in the world’s oceans reaches about 5 billion kilowatts, making it the largest reserve of ocean energy. At present, the countries engaged in ocean current energy development in the world are mainly the United States, Britain, Canada, Japan, Italy and China, among which the UK’s current-flow power generation has entered commercialization
