What are the pros and cons of hydrogen?

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 cons of hydrogen?

What are the pros of hydrogen power?

Hydrogen is an optimal energy solution in areas that are difficult to decarbonize. Hydrogen advantages include eliminating emissions to improve regional air quality while reducing greenhouse gas emissions; hydrogen reduces CO2, particulates, and NOx emissions as compared to internal combustion engines.

Is hydrogen bad for 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.

Why hydrogen is not a good fuel?

Because it has such a low energy density, hydrogen needs to be stored and transported under high pressure -- which makes it bulky and impractical. The pressure issue compounds another issue with hydrogen energy; like gasoline, hydrogen is highly flammable, but unlike gas, it has no smell.

What is Hydrogen fuel? Advantages and disadvantages of it -Stuff explained

What are the advantages pros and disadvantages cons of hydrogen technology?

What are three cons of solar?

What are cons of solar panels?

Reliability. One drawback of solar energy is that it relies on the sun, electricity cannot be generated during the night, requiring you to either store excess energy made during the day, or connect to an alternate power source such as the local utility grid.

What are the pros and cons of fossil fuels?

What are the pros for natural gas?

Is Hydrogen Fuel expensive?

At a factory-gate cost of Rs 4 to 7 per unit, green hydrogen production costs come to Rs 500 per kg. This cost compares with the current grey hydrogen cost of Rs 150 per kg.

Is hydrogen a cheap fuel?

Because hydrogen contains less energy per unit volume than all other fuels, transporting, storing, and delivering it to the point of end-use is more expensive on a per gasoline gallon equivalent basis.

Is hydrogen fuel cheaper than gasoline?

Hydrogen fuel is much more efficient than gasoline, but it's also four times more expensive, roughly equivalent to about $16 a gallon.

What are the pros and cons of wind energy?

What are fossil fuels cons?

What are cons of natural gas?

What are the pros and cons of propane?

Why solar panels are bad for the environment?

As solar panels sit in dumps, the toxic metals they contain can leach out into the environment and possibly pose a public health hazard if they get into the groundwater supply.”

Why solar panels are not worth it?

Solar panels cannot store electricity, so you will have reduced power output in cloudy weather and zero power output at night. Because of this, most residential solar systems require a solar battery. You will need to consider this additional cost when deciding if solar panels are worth it for you.
