Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water, electricity, and heat. Due to their high efficiency and zero-or near zero-emissions operation, hydrogen and fuel cells have the potential to reduce greenhouse gas emission in many applications.

Likewise, is CNG a cleaner fuel?

C.N.G (compressed natural gas) is a cleaner fuel because it causes less pollution by emitting fewer pollutants like carbon dioxide, carbon monoxide, sulphur dioxide, nitrogen dioxide, particulate matter, unburned hydrocarbons etc.

Also, is hydrogen gas cleanest fuel?

Hydrogen As A Clean Fuel. When hydrogen burns in air, it produces nothing but water vapor. It is therefore the cleanest possible, totally nonpolluting fuel.

Is hydrogen a viable fuel alternative?

One hope for our energy future lies in hydrogen -- an infinitely renewable and relatively pollution-free fuel that scientists and politicians alike see as a viable alternative to fossil fuels. And if that wasn't enough, hydrogen fuel is about three times more efficient than gasoline [source: US News].

What are the disadvantages of hydrogen?

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 exiting infrastructure.
  • It is highly flammable.
  • It is dependent on fossil fuels.

Which is the cleanest fuel?

Natural Gas

Does hydrogen pollute the air?

In fact, it's essentially pollution-free. A hydrogen fuel cell in a car produces zero emissions; the only substances released through its tailpipe are water vapor and heat. Non-renewable sources of hydrogen, such as oil and natural gas, are much cheaper, but using them still puts a drain on our fossil fuels supplies.

Is hydrogen the future?

The green hydrogen is the fuel of the future. AleaSoft, January 21, 2020. The hydrogen will be the fuel of the future and step by step it will replace all current fossil fuels.

Can you burn hydrogen without oxygen?

No. Hydrogen cannot burn without oxygen. Hydrogen is combustible or flammable - meaning, it can catch fire and burn easily only if there is an adequate supply of an oxidizer such as oxygen - to sustain enough thermal energy to keep the fire going after it has been ignited. It is a chemical reaction.

Is hydrogen better than CNG?

Answer: Hydrogen is a cleaner fuel than CNG. This is due to the reason that it produces water on burning whereas CNG on burning produces CO2, though much less than that produced when coal or oil is burnt. The increase in concentration of CO2 in the atmosphere increases the temperature of atmosphere.

Is hydrogen fuel liquid or gas?

Pound for pound, hydrogen contains almost three times as much energy as natural gas, and when consumed its only emission is pure, plain water. But unlike oil and gas, hydrogen is not a fuel. It is a way of storing or transporting energy.

Why do we not use hydrogen as a fuel in cars?

Hydrogen-burning cars are inefficient (because they rely on combustion engines, which are always inefficient, regardless of fuel), so they would cost a fair bit of money to operate. That would amount to the cost of wind or solar power used to generate the hydrogen.

Can oxygen burn?

Oxygen does not burn. It is not flammable, but it is an oxidizer. Oxygen feeds fire, so it's dangerous to use around something that is burning because it will help the fire burn much more quickly. Patients on oxygen therapy who are smokers are not going to burst into flame or explode if they smoke.

Can hydrogen be burned as fuel?

Hydrogen fuel is a zero-emission fuel burned with oxygen. It can be used in fuel cells or internal combustion engines. It has begun to be used in commercial fuel cell vehicles, such as passenger cars, and has been used in fuel cell buses for many years. The energy released enables hydrogen to act as a fuel.

Why Hydrogen is a future fuel?

In the future, hydrogen will join electricity as an important energy carrier, since it can be made safely from renewable energy sources and is virtually non-polluting. It will also be used as a fuel for 'zero-emissions' vehicles, to heat homes and offices, to produce electricity, and to fuel aircraft.

How much is a gallon of hydrogen?

Cost to refill. Long Answer: Hydrogen fuel prices range from $12.85 to more than $16 per kilogram (kg), but the most common price is $13.99 per kg (equivalent on a price per energy basis to $5.60 per gallon of gasoline), which translates to an operating cost of $0.21 per mile.

How safe is hydrogen fuel?

The short answer is that hydrogen behaves differently from gasoline. But generally it is about as safe as the gasoline we now put in most vehicles' fuel tanks. Its vapors don't pool on the ground, as do gasoline's heavier-than-air vapors. So in most cases, hydrogen doesn't present as great a fire or explosive danger.

Is hydrogen clean energy?

Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Hydrogen is an energy carrier that can be used to store, move, and deliver energy produced from other sources. Today, hydrogen fuel can be produced through several methods.

Where does most hydrogen come from?

Currently, most hydrogen is produced from fossil fuels, specifically natural gas. Electricity—from the grid or from renewable sources such as wind, solar, geothermal, or biomass—is also currently used to produce hydrogen. In the longer term, solar energy and biomass can be used more directly to generate hydrogen.

What products are made from hydrogen?

Hydrogen combines with other elements to form numerous compounds. Some of the common ones are: water (H2O), ammonia (NH3), methane (CH4), table sugar (C12H22O11), hydrogen peroxide (H2O2) and hydrochloric acid (HCl).

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

=>It is very expensive to produce hydrogen from electrolysis of water. =>It is very difficult to store and transport hydrogen because it is explosively inflamable. 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..
