    Btu Water
In summary, Hydrogen compares to gasoline or diesel fuel for BTU which is the basic comparison for energy sources. It is more expensive to make Hydrogen from water than using fossil fuels, but it does not produce pollution when burned.

I would like to know how Hydrogen compares to gasoline or diesel fuel for BTU which is the basic comparison for energy sources. If water is relatively easy to get, then the cost of hydrogen production is irrelevant. but gasoline on the other hand is expensive and controlled by a few individuals.
BTW, it is H2O not HO2 so you get 2 parts Hydrogen and 1 part Oxygen.

This source mentions that hydrogen gas contains 61,000 Btus of latent energy per pound compared to regular gasoline which has 20,500 Btus per pound. Of course it also mentions that a pound of hydrogen gas takes up about 10,000 times the space that gasoline does...:

Making Hydrogen gas from water to use as a fuel is much more expensive than simply using fossil fuels to do the task (the above site does a good job of explaining why)...the only real benefit over using gasoline is that you do not have pollution when burning hydrogen.

Whatever society uses to run itself will always be controlled by a few individuals. In the Roman times, salt was a controlled substance that was used as payment and doled out in small increments to the everyday people. If I had the same access to salt now while living then I would be a Roman kajillionaire! But times change and new substances become "precious" to the running of society such as coal in the late 1800's or fossil fuels now. If a new fuel is found, be assured it will be controlled by the same sorts of people (and fossil fuels will probably still be available at that time; and nobody will really use them because everyone will have switched over to this new controlled fuel!). Seen from that perspective, I am sort of happy that water likely won't become the new substance used to run society (after all, we need it to drink!).

1. What is the difference in energy released between burning water and burning gasoline?

Burning gasoline releases significantly more energy than burning water. This is due to the chemical composition of gasoline, which contains hydrocarbons that are easily combustible and release a large amount of heat when burned.

2. How do the combustion processes of burning water and burning gasoline differ?

The combustion process of burning water involves breaking down the water molecule into its component elements, hydrogen and oxygen, which then react with oxygen in the air to release heat. Burning gasoline, on the other hand, involves the combustion of hydrocarbons in the presence of oxygen to produce carbon dioxide and water vapor, which also release heat.

3. Why is it not possible to burn water as a fuel source?

Water cannot be burned as a fuel source because it is already in its most stable form. The energy required to break the bonds between hydrogen and oxygen in water is greater than the energy released from burning it. Therefore, burning water as a fuel source would require more energy input than it would produce.

4. Can water be used as an energy source in any other way?

While water cannot be directly burned as a fuel source, it can be used for its energy storage capabilities. For example, hydropower plants use the energy from flowing water to generate electricity. Additionally, water can be used as a coolant in nuclear power plants to transfer heat and generate electricity.

5. How does the environmental impact of burning water compare to burning gasoline?

Burning water does not produce any harmful emissions, as the only byproduct is water vapor. In contrast, burning gasoline releases carbon dioxide and other pollutants into the atmosphere, contributing to air pollution and climate change. Therefore, burning water has a much lower environmental impact than burning gasoline.
