Hydrogen, which is expected to be an energy carrier, can be obtained from water using any primary energy source like solar energy, electricity or thermal energy or a hybrid system consisting of more than one of these primary energy sources.

• 利用任何初级的能源，如太阳能、电能、热能或者包括不止一种基本形式能源的混合能，人们就可以从水中获得期望成为能量的载体氢。
