The sceptics’ first argument against hydrogen vehicles is that they’re less efficient than EVs are. Because hydrogen doesn’t occur naturally, it has to be extracted, then compressed in fuel tanks. “Lithium-ion battery production [for electric vehicles] is very energy-intensive.

Why are hydrogen cars not popular?

The sceptics’ first argument against hydrogen vehicles is that they’re less efficient than EVs are. Because hydrogen doesn’t occur naturally, it has to be extracted, then compressed in fuel tanks. “Lithium-ion battery production [for electric vehicles] is very energy-intensive.

Is hydrogen fuel the future?

Green hydrogen, produced using renewable energy, could decarbonise some of the most energy-intensive [+] Hydrogen has been the fuel of the future for decades, always promising to deliver huge benefits in about five years’ time.

Which of the following is a disadvantage of using hydrogen fuel cells?

1) Although Hydrogen cells are being used to power hybrid cars, it’s still not a feasible source of fuel for everyone. It is expensive. 2) The transport and storage of Hydrogen, even in small amounts is difficult. 3) As of the moment the present infrastructure supports gasoline, replacing it requires refitting.

Why is it difficult to use hydrogen as a source of energy?

it is difficult to use hydrogen as a source of energy because it is highly inflammable and it’s cost is very expensive! that’s why..

Are hydrogen cars bad for the environment?

Ideally, a hydrogen fuel-cell vehicle has no environmental impact. By comparison, the internal combustion engine uses fossil fuels and produces many pollutants, including soot, noxious nitrogen and sulfur gases, and the “greenhouse gas” carbon dioxide.

Are hydrogen cars good for the environment?

The Benefits of Hydrogen Over Fossil Fuels The only by-product of running a hydrogen-powered fuel cell is oxygen and a trickle of water, neither of which will cause any harm to human health or the environment.

What are the advantages of hydrogen energy?

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.

Why hydrogen is not used as a fuel?

Drawbacks. Hydrogen fuel is hazardous because of the low ignition energy and high combustion energy of hydrogen, and because it tends to leak easily from tanks.

What are the advantages of fuel cell?

Fuel cells have lower emissions than combustion engines. Hydrogen fuel cells emit only water, so there are no carbon dioxide emissions and no air pollutants that create smog and cause health problems at the point of operation. Also, fuel cells are quiet during operation as they have fewer moving parts.

What are the advantages of using hydrogen?

Advantages of Hydrogen Energy

  • It’s a Renewable Energy Source and Bountiful in Supply.
  • Numerous Sources to Produce Hydrogen Locally.
  • It is Practically a Clean Energy Source.
  • Hydrogen Energy is Non-toxic.
  • The Use of Hydrogen Greatly Reduces Pollution.
  • It’s Far More Efficient Than Other Sources of energy.

Does fuel cell have a future?

Possible Uses. In the future, fuel cells could power our cars, with hydrogen replacing the petroleum fuel that is used in most vehicles today. Many vehicle manufacturers are actively researching and developing transportation fuel cell technologies. Stationary fuel cells are the largest, most powerful fuel cells.

What’s bad about hydrogen?

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.

How dangerous are hydrogen cars?

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.

What is one disadvantage of each alternative fuel?

List of the Disadvantages of Alternative Energy

  • Some forms of alternative energy still produce pollutants.
  • Many forms of alternative energy are not continuous.
  • Alternative energy resources can adversely impact nature.
  • Cost is an important factor to consider with alternative energy.

What are the advantages and disadvantages of using hydrogen as a fuel?

Hydrogen Fuel Cell Advantages and Disadvantages in Material Handling

  • Hydrogen Fuel Cell Technology.
  • Advantage: High Energy Density Improves Productivity.
  • Disadvantage: The Use of Fossil Fuels in Hydrogen Production.
  • Disadvantage: Hydrogen Storage and Transportation.
  • Disadvantage: Fuel Cell Efficiency.

Why hydrogen is the best fuel?

This is because hydrogen gas is lighter than air and rises into the atmosphere as a result. Natural hydrogen is always associated with other elements in compound form such as water, coal and petroleum. Hydrogen has the highest energy content of any common fuel by weight.

What are the pros and cons of alternative energy?

Pros: It is abundant, and can be used without interruption, cleaner than fossil fuel. Cons: Can result in air pollution, takes a lot of energy to produce, can be seasonable and competes with food production. Landfill gas, solid waste energy comes from harnessing the decomposition of organic material.

How does hydrogen energy affect the environment?

Emissions of hydrogen lead to increased burdens of methane and ozone and hence to an increase in global warming. Therefore, hydrogen can be considered as an indirect greenhouse gas with the potential to increase global warming.

What are the pros and cons of hydrogen energy?

Hydrogen fuel cells Pros: No vehicle emissions other than water vapor. Fuel economy equivalent to about twice that of gasoline vehicles. Hydrogen is abundant, and can be made from renewable energy. Cons: This space-age technology is expensive.

What are the disadvantages of a fuel cell?


  • Expensive to manufacture due the high cost of catalysts (platinum)
  • Lack of infrastructure to support the distribution of hydrogen.
  • A lot of the currently available fuel cell technology is in the prototype stage and not yet validated.
  • Hydrogen is expensive to produce and not widely available.
