Which is not a drawback of using fossil fuels?
Answer: A) They release radioactive waste. Explanation: Fossil fuels are non renewable resources do not release radioactive wastes / materials, but they do release greenhouse gases, causing air pollution.
What is a major disadvantage of many alternatives fuels?
Biodiesel cars. One of the major cons of biodiesel fuel is its cost, being more expensive to produce than regular diesel. Another hazard is seen as the temptation for farmers to turn to growing biodiesel plants rather than food crops.
What is the downside of hydrogen fuel?
Hydrogen fuel cells Cons: This space-age technology is expensive. Acceptable range requires extremely-high-pressure, on-board hydrogen storage. Few places to refuel. Hydrogen is very expensive to transport and there is no infrastructure in place yet.
What are the benefits of alternative fuels?
Whether produced via conventional or renewable methods, the advantages of natural gas as an alternative fuel include its domestic availability, established distribution network, relatively low cost, and emissions benefits.
Which is the best alternative fuel?
Top nine alternative fuels for cars
- Biofuel. Biofuels such as bioethanol (which can be used instead of petrol), are made from corn and sugarcane, whereas biodiesel is made from vegetable oils and animal fats.
- Electricity.
- Steam.
- Kinetic.
- Heat.
- Hydrogen.
- Air.
- Nitrogen.
How does alternative fuel affect the environment?
But diesel and gasoline fuels are of environmental concern because burning the fuel emits carbon dioxide, nitrous oxide and methane. Alternative fuels are meant to reduce greenhouse gases, which include water vapor, carbon dioxide, methane, nitrous oxide and ozone. Biodiesel is used in standard diesel engines.
Is liquid 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.
How will hydrogen help reduce pollution?
When compressed hydrogen is used in a fuel cell, its only byproducts are electricity, clean water and heat, meaning that hydrogen-powered vehicles and equipment release zero pollutants or greenhouse gases into the air.
Are fuel cells environmentally friendly?
Hydrogen fuel cells have been widely touted as an environmentally-friendly alternative to conventional fossil fuels. By oxidising molecular hydrogen, the only direct by-product of their energy generation is water, which means they could significantly reduce pollution and man-made greenhouse gases.
Are hydrogen cars bad for environment?
Check our Privacy Policy. In terms of emissions, burning hydrogen for energy doesn’t hurt the environment, as the only byproducts it releases are heat and water. Still, hydrogen can also be separated from water through a process called electrolysis, which can be powered by wind, solar or other renewable energy sources.
Are hydrogen cars more environmentally friendly?
The Canadian Hydrogen and Fuel Cell Association recently produced a report extolling hydrogen vehicles. Among other points, it said that the carbon footprint is an order of magnitude better than electric vehicles: 2.7g of carbon dioxide per kilometre compared to 20.9g.
