氢气是一种发热值很高的气体燃料.燃烧1kg氢气可以产生14万千焦的热量,这个发热值相当于煤的4倍、汽油的3倍.全世界137亿亿吨海水中,可以分解出16亿亿吨氢气.而且氢气燃烧生成的水又可以循环使用,可以说在任何时候都不会枯竭.氢气在燃烧中不会生成烟尘和废气,对环境没有污染.目 Hydrogen is a gas fuel with a high calorific value. Burning 1 kg of hydrogen can produce 140,000 kilojoules of heat. This calorific value is equivalent to 4 times that of coal and 3 times that of gasoline. It can be decomposed in 137 billion tons of seawater worldwide. Out of 1.6 billion tons of hydrogen, and the water generated by the hydrogen combustion can be recycled, it can be said that it will not be exhausted at any time. The hydrogen will not generate smoke and exhaust gas in the combustion, no pollution to the environment.
