Question

hydrogen has been used as a rocket fuel. would you consider it as a more clean fuel than cng why or why not​

Answer 1

Answer:

• Hydrogen gas is more environmentally friendly than compressed natural gas (CNG). Because CNG contains hydrocarbons, this is the case.
• CNG contains carbon, which is a pollutant. Hydrogen, on the other hand, is waste-free, and hydrogen fusion produces no waste. As a result, hydrogen is a cleaner rocket fuel than CNG.

Explanation:

When hydrogen is burnt with oxygen, it produces no emissions. When the fuel cell is fuelled by pure hydrogen, it can achieve an efficiency of up to 80%. In other words, 80% of the hydrogen energy is transformed to electrical energy. So we have an 80 percent efficiency in creating electricity and an 80 percent efficiency in converting it to mechanical power.
