Why is hydrogen not used as fuel?

Storage of hydrogen fuel cells is much more complicated and expensive than other fuel types. This adds to the overall costs of products and raises prices for automakers. The fuel cell can be dangerous due to its highly flammable nature. This makes it a dangerous fuel to have in a vehicle if it crashes.

What are the challenges for hydrogen as fuel?

To use hydrogen as a fuel possesses many challenges because of its high flammability, high diffusivity and very low density as a gas. Hydrogen can be transported as a pressurized gas or adsorbed on a substrate, etc. Another serious drawback faced in the usage of Hydrogen today is the storage issue.

Why hydrogen is used as a fuel?

The interest in hydrogen as an alternative transportation fuel stems from its ability to power fuel cells in zero-emission vehicles, its potential for domestic production, and the fuel cell’s fast filling time and high efficiency.

What are the disadvantages of hydrogen?

Disadvantages of Hydrogen Energy

• Hydrogen Energy is Expensive.
• Storage Complications.
• It’s Not the Safest Source of Energy.
• Tricky to Move Around.
• It is Dependent on Fossil fuels.
• Hydrogen Energy Cannot Sustain the Population.

Why hydrogen storage is difficult?

Hydrogen is difficult to store because has very low volumetric energy density. Hydrogen is 3.2 times less energy dense than natural gas and 2700 times less energy dense than gasoline. Hydrogen contains 3.4 times more energy than gasoline on a weight basis.

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

Hydrogen Fuel Cell Advantages and Disadvantages in Material…

• 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.

What is hydrogen used for in industry?

Nearly all of the hydrogen consumed in the United States is used by industry for refining petroleum, treating metals, producing fertilizer, and processing foods. U.S. petroleum refineries use hydrogen to lower the sulfur content of fuels.

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

What are the advantages and disadvantages of hydrogen fuel?

Hydrogen fuel cells provide an inherently clean source of energy, with no adverse environmental impact during operation as the byproducts are simply heat and water. Unlike biofuel or hydropower, hydrogen doesn’t require large areas of land to produce.

How is hydrogen produced commercially?

There are four main sources for the commercial production of hydrogen: natural gas, oil, coal, and electrolysis; which account for 48\%, 30\%, 18\% and 4\% of the world’s hydrogen production respectively. Specifically, bulk hydrogen is usually produced by the steam reforming of methane or natural gas.

Why hydrogen is a good fuel?

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.
