Why is hydrogen considered as a clean fuel?

Why is hydrogen considered as a clean fuel?

Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water, electricity, and heat. Due to their high efficiency and zero-or near zero-emissions operation, hydrogen and fuel cells have the potential to reduce greenhouse gas emission in many applications.

Which is better CNG or hydrogen?

CNG and compressed hydrogen are compared to illustrate why CNG, but not compressed hydrogen, is a viable alternative vehicle fuel. It is shown that natural gas has a greater energy content per mole than hydrogen and that more moles of natural gas than hydrogen may be stored in a given volume under identical conditions.

Which of the two is cleaner fuel hydrogen or CNG?

Answer: Hydrogen is a cleaner fuel than CNG. This is due to the reason that it produces water on burning whereas CNG on burning produces CO2, though much less than that produced when coal or oil is burnt. The increase in concentration of CO2 in the atmosphere increases the temperature of atmosphere.

Which is considered a cleaner fuel petroleum or CNG Why?

Answer Expert Verified CNG is the compressed natural gas and cause less pollution as compared to other source of fuels like coal . The carbon dioxide and nitrogen oxide as well as the sulphur oxide are produced less than the petroleum or coal etc . That’s why CNG is called the Clean fuel.

Why hydrogen is not used as a fuel?

Hydrogen has the highest calorific value so it can be considered as the best fuel but it is highly inflammable so it is diificult to store, transport and handle so it is used as a fuel only where it is absolutely necessary.

What are the advantages of using hydrogen as a fuel class 11?

Advantages of Hydrogen Fuel: On burning hydrogen, it emits only water vapour, When hydrogen is burned it does not produce carbon dioxide. Hydrogen deletes little tailpipe pollution and is considered less of a pollutant. It has the ability to run a fuel-cell engine when compared to an internal combustion engine.

Can hydrogen be used as a fuel?

Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Today, hydrogen fuel can be produced through several methods. The most common methods today are natural gas reforming (a thermal process), and electrolysis. Other methods include solar-driven and biological processes.

What is hydrogen CNG?

According to a report by TOI, HCNG is a hydrogen-enriched compressed natural gas (CNG). In Delhi, instead of physically blending hydrogen with CNG, hydrogen spiked CNG will be produced using a compact reforming process patented by Indian Oil Corporation.

Why are we looking at alternate source of energy?

The main reason why we are searching for an alternate source of energy is because fossil fuels are non-renewable sources of energy which means they are not available in abundant quantities and cannot be replenished. Fossil fuels will continue to get exhausted if their consumption is not controlled.

Why CNG is considered as a better fuel class 8?

CNG stands for Compressed Natural Gas.It is better because it is an eco-friendly gas and causes no harm to the environment. Since CNG is a clean burning fuel, combusting it leaves little or no residue compared to gasoline or diesel. Thus, the damage to the pipes and tubes of the vehicle’s engine is greatly reduced.

Which fuel is known as clean fuel and why?

CNG is nothing but Compressed Natural Gas. It is made by compressing natural gas, to less than 1 percent of the volume, it occupies at Standard Atmospheric pressure. Natural gas is mainly composed of Methane.
