Sample Comparative Essay: Hydrogen vs. Electric Cars.

Hydrogen is one such fuel that has the potential to be a cheaper, more efficient and cleaner alternative to gasoline. Although hydrogen-powered fuels have been under development for decades, they still remain in the short-term a much more expensive option than gasoline-powered cars.

Hydrogen cars, or, hydrogen fuel cell cars - as they are correctly known, were first introduced by Toyota in 2014 and have kept a pretty low profile since then. Here we take a closer look, answering the questions: what exactly is a hydrogen car, how is the technology progressing, should you buy one and what ones are available to buy now.

Compare And Contrast Essay About Gas Powered Cars And Electrical Car. Completely to Electric Cars?Everyday gas powered cars destroy the environment and the people that drive these gas guzzlers pay a ton of money to use them. Many people think that gas powered cars are better than electric cars, but they do not know the real truth.After you read this paper you will understand why electric cars.

The fuel cell and hydrogen tanks on a fuel-cell vehicles simply replace most of the larger battery pack that a battery-electric vehicle uses. Once the electrons start flowing, both types of vehicle are powered the same way, by electric motors.

Another advantage of gas-powered cars is when it comes to raw power. Some hybrid-electric cars, especially early models, may compromise on power for better fuel efficiency. This is a result of carrying the added weight of the batteries as well as the limited output of an electric motor.

In many cases, hydrogen is safer than the fuel we currently use to power our cars. Carbon-based fuels tend to spread as liquids (as you well know if you've ever spilled gasoline on yourself at the pump). When it burns, conventional fuel produces hot ash, creating radiant heat.

On an average, a hydrogen-powered car will give up to 60 miles for every kilogram of hydrogen, which seems like a good deal. Cons of Hydrogen Cars. The cost incurred in preparing the fuel cells for such cars is quite high. This is because the working of these fuel cells involve platinum, which is scarcely found, and is moreover a very expensive.

Here's why hydrogen-fueled cars aren't little Hindenburgs Hydrogen is explosive, but supply is a bigger issue for the nascent industry. than gasoline. If a regular car's fuel tank is punctured.

Hydrogen is a very efficient fuel source, capable of producing more energy per pound of fuel than gasoline. This means that an equal-sized tank of hydrogen fuel would give a vehicle a greater range or more power than when filled with gasoline and an internal combustion engine.

Batteries are still nowhere close to what gasoline cars or hydrogen cars can carry. A battery-powered car carries about the same amount of energy as a couple of gallons (or, say, about 10 liters.

Hydrogen's flammability range (between 4% and 75% in air) is very wide compared to other fuels, as shown in Figure 3. Under the optimal combustion condition (a 29% hydrogen-to-air volume ratio), the energy required to initiate hydrogen combustion is much lower than that required for other common fuels (e.g., a small spark will ignite it), as shown in Figure 4.
