- IC engines use the energy stored in the chemical bond between the molecules.when Hydrogen and oxygen are combined releasing enormous energy.
- The energy released from Hydrogen is the highest of all substances. Thus hydrogen is good fuel but dangerous as it burns with almost invisibleflame and even a minor leaks auto ignite leading to big explosions.
- They store the hydrogen energy in the form of hydrides in a very safe mode
- Water is the by product of combustion and thus cannot be used as fuel.
- A water molecule contains three atoms: an oxygen atom and two hydrogen atoms, which bond together like magnets. According to Wai Cheng, a professor of mechanical engineering and director of the Sloan Automotive Lab.He said
- The atomic mass of a hydrogen atom is 1 whereas for oxygen, it is 16.
- During combustion, compound of water is formed by liberating a large amount of energy and the compound attains a highly stable state. So, basically water itself does not have any energy to liberate.
- Build a car and arrange equipment to split a water molecule apart and separate its oxygen and hydrogen. Then it would need to isolate each of them in separate tanks. Then you would need a combustion system that could mix and ignite them, or a fuel cell that could recombine them to make electricity. The released energy could then drive a piston or run a motor and move the car.
- Here’s the problem, “A water molecule is very stable.” The energy needed to separate the atoms is greater than what you get back
