What will happen to all our water when hydrogen is our new energy source?
I want to know where all our water (H2O) will go when hydrogen officially becomes our fuel source. You can say that we have enought water in our oceans, but the hard fact is that it's NaCH2O ( Saltwater) if we use up all the hydrogen in the water, then what will be left for us to drink when all our water is gone?
Do you know ??? /////////////////
When Hydrogen is used in a fuel cell it combines with Oxygen to make water? If all the water on earth was turned to Hydrogen, it would all be regenerated when used in a fuel cell.
NaCH2O is not salt water? In fact, this molecule does not exist. I believe what you are thinking about is NaCl. This is table salt. Saltwater is about 3% salt by weight. The rest is almost entirely water, H2O.
////////////////// hydrogen will never replace all our fuel
1.) Making Hydrogen requires a lot of energy
Hydrogen combines with Oxygen producing so much heat energy there is an explosion. Basically the same sort of thing happens in an engine when gasoline is burned. The heat energy is then available to be transformed into mechanical energy. However, a fundamental physical law says energy can never be created nor destroyed. What this means is that the energy stored in the Hydrogen must be re-supplied to water to reform more hydrogen. Concidering the amount of force Hydrogen generates when it burns, this is quite a lot of energy.
2.) Free energy is the best, but there's not enough of it.
Producing Hydrogen from water involves using electricity to split 2 molecules of H2O into 2 molecules of H2 and a molecule of O2. At this point, the clock is completely wound and ready to start ticking. The trick is in finding the energy needed to wind the clock. In terms of electricity, it has most often been falling water. Gravity is used to turn a rotor which generates the electricity to produce the Hydrogen. The point here is that burning fossil fuel to produce steam to make electricity to make Hydrogen is absolutely impractical economically. Under these circumstances, more energy would be required to produce the Hydrogen than the energy available from the Hydrogen itself. This is why free energy is needed. Hydroelectric and geothermal power plants are the only possible means of producing Hydrogen. Nucleur energy is not possible, because the nucleur fuel is so expensive. Hydroelectric and geothermal factories require the right locations. Unfortunately waterfalls and giesers are not especially common.
