Are hydrogen fuel cells considered renewable?
It can be extracted from renewable biomass or coal using high temperature gasification. Or, using chemical catalysts, it can be derived from renewable biogas, renewable ethanol or methanol, or fossil natural gas. Today, most hydrogen is derived from fossil natural gas, emitting fossil carbon dioxide as a by-product.
Is hydrogen renewable or nonrenewable?
Although hydrogen energy is renewable and has minimal environmental impact, other non-renewable sources such as coal, oil and natural gas are needed to separate it from oxygen. While the point of switching to hydrogen is to get rid of using fossil fuels, they are still needed to produce hydrogen fuel.
Which of these is a disadvantage of hydrogen fuel apex?
Explanation: Disadvantage :Hydrogen fuel is expensive to produce and transport.
Which of the following is a disadvantage of hydrogen fuel cells apes?
Which of the following is a disadvantage of using hydrogen fuel cells? Hydrogen gas is not readily available on Earth. The products of the reactions in hydrogen fuel cells damage the environment. Hydrogen fuel cells are much less efficient in powering vehicles than internal combustion engines are.
Are hydrogen fuel cells less efficient?
Hydrogen-powered fuel cells are not only pollution-free, but also can have more than two times the efficiency of traditional combustion technologies.
Are hydrogen fuel cells efficient?
Why Fuel Cells? Hydrogen fuel cell vehicles, which use electric motors, are much more energy efficient and use 40-60 percent of the fuel’s energy — corresponding to more than a 50% reduction in fuel consumption, compared to a conventional vehicle with a gasoline internal combustion engine.
Which sentence describes disadvantages of burning fossil fuels instead of hydrogen fuel cells?
Which sentences describe disadvantages of burning fossil fuels instead of using hydrogen fuel cells? Burning fossil fuels contributes to climate change. Burning fossil fuels takes place inside expensive fuel cells. Fossil fuels aren’t widely available, but pure hydrogen is.
