由包括英国在内的16个国家资助的一艘科学考察船将于明年前往美国北卡罗来纳州附近的大西洋海域,开始试验性的海底水化物钻探。这里1100平方英里的海域,据认为含有的甲烷储量是美国目前甲烷年消耗量的20倍。 全世界海底含有的尚未开发的甲烷足够供应世界对电力的需求达数百年。在海底的沉积岩里以水化物形式存在的甲烷约达10万亿吨以上。 1810年,科学家汉弗雷·戴维在试验中发现了水化物,但只是在最近人们才认识到它存在于各大海洋里。当
A scientific expedition ship, funded by 16 countries, including the United Kingdom, will begin its pilot submarine hydrate drilling next year to the Atlantic Ocean near North Carolina. Here 1,100 square miles of sea, it is thought to contain methane reserves is 20 times the current annual consumption of methane in the United States. The untapped methane contained in the seabed of the world is enough to supply the world with hundreds of years of demand for electricity. Methane in the form of hydrates in the seabed sediments is about 10 trillion tons or more. In 1810, scientist Humphrey David discovered hydrates in the experiment, but only recently has it been realized that it exists in every ocean. when
