Difference Between Hydrogen Cars and Electric Cars

Difference Between Hydrogen Cars and Electric Cars

However, as hydrogen cars densely pack their energy storage, they're usually able to achieve longer distances. While most fully electric vehicles can travel between 100-200 miles on a single charge, hydrogen ones can get to 300 miles, according to AutomotiveTechnologies.

Are hydrogen cars better than electric cars?

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. It then has to mix with oxygen in a fuel cell stack to create electricity to power the car's motors.

What is the difference between electric and hydrogen cars?

Fuel cell vehicles are also driven by an electric motor, but instead of being powered by a battery, they create the electricity in an onboard fuel cell, usually using oxygen from the air and stored hydrogen. ... The difference is, "with a fuel cell, you're able to decouple energy conversion from energy storage," he said.

Why Hydrogen cars are a bad idea?

The reason why hydrogen is inefficient is because the energy must move from wire to gas to wire in order to power a car. ... Once inside the vehicle, the hydrogen needs converted into electricity, which is 60% efficient. Finally the electricity used in the motor to move the vehicle is is around 95% efficient.

What are the disadvantages of hydrogen cars?

What are the Disadvantages of Hydrogen Fuel Cells?

Why electric cars will never work?

Electric cars are severely limited by several drawbacks, including: A shortage of charging stations. High electricity costs. Disappointing battery capacity that limits the distance the cars can be driven between charges.

What are the disadvantages of having an electric car?

What Are the Disadvantages of Owning an Electric Car?

Why are electric cars bad for the environment?

Electric cars have fewer emissions

Direct emissions are emitted through a car's tailpipe and contribute to smog — fog combined with smoke or a pollutant. ... In northern China, where coal dominates electricity generation, electric cars were found to emit slightly more greenhouse gases than traditional cars.

Why are fuel cells so expensive?

Fuel cells are very costly because they are complex and require expensive materials such as platinum. ... Liquid fuel cells are an attractive alternative to traditional hydrogen fuel cells because they minimize the need to transport and store hydrogen.

How much does a tank of hydrogen cost?

Long Answer: The average price of hydrogen for a light-duty fuel cell electric vehicle (passenger car) in California is $16.51 per kilogram, according to the 2019 Joint Agency Report (p17).

Can hydrogen fuel cells explode?

So in most cases, hydrogen doesn't present as great a fire or explosive danger. To further minimize the potential for explosion, almost all hydrogen fuel stations store the gas above the ground in well-vented areas.

What are the problems with hydrogen fuel cells?

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 bad about hydrogen fuel cells?

Hydrogen fuel cells have bad theoretical and practical efficiency. Hydrogen storage is inefficient, energetically, volumetrically and with respect to weight.
