What energy does an engine produce?
Q: The internal combustion engine converts thermal energy to another form of energy. Which form of energy is it? A: The engine converts thermal energy to kinetic energy, or the energy of a moving object—in this case, the moving piston.
Does a hydrogen economy make sense?
Because of the high energy losses within a hydrogen economy the synthetic energy carrier cannot compete with electricity. As the fundamental laws of physics cannot be chanced by research, politics or investments, a hydrogen economy will never make sense.
How do we get hydrogen energy?
To produce hydrogen, it must be separated from the other elements in the molecules where it occurs. There are many different sources of hydrogen and ways for producing it for use as a fuel. The two most common methods for producing hydrogen are steam-methane reforming and electrolysis (splitting water with electricity.
Why hydrogen is the best source of energy?
However, hydrogen is useful as an energy source/fuel because it has a high energy content per unit of weight, which is why it is used as a rocket fuel and in fuel cells to produce electricity on some spacecraft.
Which is important for hydrogen production?
The most important industrial method for the production of hydrogen is the catalytic steam–hydrocarbon process, in which gaseous or vaporized hydrocarbons are treated with steam at high pressure over a nickel catalyst at 650°–950° C to produce carbon oxides and hydrogen: CnH2n+2 + nH2O → nCO + (2n + 1)H2; CnH2n+2 + 2nH …
What are the downsides to hydrogen fuel cells?
What are the Disadvantages of Hydrogen Fuel Cells?
- Hydrogen Extraction.
- Investment is Required.
- Cost of Raw Materials.
- Regulatory Issues.
- Overall Cost.
- Hydrogen Storage.
- Infrastructure.
- Highly Flammable.
What are the dangers of hydrogen power?
The two prime dangers from fuel cell and hydrogen-powered vehicles are the danger of electrical shock and the flammability of the fuel. Fuel cells power vehicles by electro-chemically combining hydrogen gas (H2) and oxygen (O2) from the surrounding air into water (H20) and electrical energy.
