What are the advantages of hydrogen as a fuel class 9?
What are the advantages of hydrogen as a fuel class 9?
(ii) Hydrogen has more calorific value than petrol and other fuels. For example 9-5kg of liquid of hydrogen can evolve as much energy on combustion as 25kg of petro. (iii) In space rockets, liquid hydrogen gives higher upward thrust as compared to other fuels.
Why is hydrogen gas not used as a fuel?
But it is not used as domestic fuel, due to several reasons : Hydrogen is not easily available and cost of production is high Unlike other gases, hydrogen is not readily available in the atmosphere. It requires processes like electrolysis of water for its production. This is a very costly process and time consuming.
What are the advantages of using hydrogen as fuel class 8?
A. High calorific value.
What are the advantages of hydrogen cars?
Fuel cell electric vehicles (FCEVs) are powered by hydrogen. They are more efficient than conventional internal combustion engine vehicles and produce no tailpipe emissions—they only emit water vapor and warm air.

Which of the following is the advantage of the hydrogen as a fuel Mcq?
Which of the following is the advantage of the hydrogen as a fuel? Explanation: The advantage of hydrogen fuel is no hydrocarbon and CO emissions.
What are the disadvantages of using hydrogen as a fuel class 11?
List of Disadvantages of Hydrogen Fuel Cells
- It is expensive. While widely available, hydrogen is expensive.
- It is difficult to store. Hydrogen is very hard to move around.
- It is not easy to replace the existing infrastructure.
- It is highly flammable.
- Fossil fuels are often used to produce it.
What are the advantages and disadvantages of hydrogen fuel?
Hydrogen is a much lighter gas than gasoline which makes it difficult to store and transport. To be able to store it we need to compress it into a liquid and store it at a low temperature. The high amounts of pressure needed to store hydrogen makes it a difficult fuel to transport in large quantities.
What is an advantage of using hydrogen as a fuel quizlet?
Hydrogen-rich fuel cells produce less CO₂ than hydrocarbon fuels. Hydrocarbon fuels may undergo incomplete combustion producing toxic carbon monoxide. Hydrogen fuel cell vehicles are more efficient (40-60% efficient) as hydrocarbon fuels (20% efficient) waste chemical energy though heat loss.
What are the advantages of using hydrogen?

Which of the following is a advantage of the hydrogen as a fuel?
Hydrogen can be produced from diverse domestic resources with the potential for near-zero greenhouse gas emissions. Once produced, hydrogen generates electrical power in a fuel cell, emitting only water vapor and warm air. It holds promise for growth in both the stationary and transportation energy sectors.
What is the advantage of hydrogen as a fuel in an IC engine?
Hydrogen has very low ignition energy. The amount of energy needed to ignite hydrogen is about one order of magnitude less than that required for gasoline. This enables hydrogen engines to ignite lean mixtures and ensures prompt ignition.
What are the advantages of hydrogen energy?
What are advantages of hydrogen?
What is an advantage of hydrogen fuel?
Hydrogen fuel cells (HFCs) produce no harmful emissions, eliminating the costs associated with handling and storing toxic materials like battery acid or diesel fuel. In fact, when fueled with pure hydrogen, the only by-products are heat and water, making our products a zero-emission, sustainable power source.
What are the advantages and disadvantages of using hydrogen gas as an alternate fuel source?
What are some advantages of hydrogen?
What is advantage of using hydrogen as fuel Mcq?
Explanation: Hydrogen fuel is a clean source of energy. It is a zero-emission fuel burned with oxygen and is used in different applications to generate electricity. Among all sources of energy, burning fossil fuels produces maximum amount of greenhouse gases. 3.
What are the benefits of hydrogen energy?
Hydrogen is an optimal energy solution in areas that are difficult to decarbonize. Hydrogen advantages include eliminating emissions to improve regional air quality while reducing greenhouse gas emissions; hydrogen reduces CO2, particulates, and NOx emissions as compared to internal combustion engines.
Why hydrogen is a good energy source?
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. Hydrogen is not widely used as a fuel now, but it has the potential for greater use in the future.
