Question 1:

Which of the following is an example of an algae-based fuel?

A) Ethanol
B) Biodiesel
C) Hydrogen
D) Methanol

Show Answer

Explanation: The correct answer is B) Biodiesel. Algae-based fuels are primarily used in the production of biodiesel. Algae contain lipids that can be converted into biodiesel through processes such as transesterification. Algae-based biodiesel offers the potential for sustainable and renewable fuel production.

Question 2:

Which alternative fuel technology uses ammonia as a fuel?

A) Hydrogen fuel cells
B) Ethanol production
C) Ammonia fuel cells
D) Biogas production

Show Answer

Explanation: The correct answer is C) Ammonia fuel cells. Ammonia can be used as a fuel in fuel cells to generate electricity. Ammonia fuel cells work by oxidizing ammonia to produce electrical energy, with water and nitrogen as the byproducts. This technology shows promise as a clean and efficient alternative fuel option.

Question 3:

What is a potential advantage of algae-based fuels?

A) High energy density
B) Compatibility with existing infrastructure
C) Low production cost
D) Reduction in greenhouse gas emissions

Show Answer

Explanation: The correct answer is D) Reduction in greenhouse gas emissions. One potential advantage of algae-based fuels is their ability to reduce greenhouse gas emissions. Algae consume carbon dioxide during their growth, offsetting the carbon emissions when the fuel is burned. Additionally, algae-based fuels have the potential to be produced sustainably and can help reduce dependence on fossil fuels.

Question 4:

Which emerging alternative fuel technology has the potential to be carbon-neutral?

A) Algae-based fuels
B) Synthetic natural gas
C) Hydrogen fuel cells
D) Ammonia as a fuel

Show Answer

Explanation: The correct answer is A) Algae-based fuels. Algae-based fuels have the potential to be carbon-neutral or even carbon-negative. During their growth, algae absorb carbon dioxide from the atmosphere, and when the fuel is burned, the emissions can be offset by the carbon dioxide absorbed by new algae. This cycle can result in a net reduction in carbon emissions compared to conventional fossil fuels.

Question 5:

What is a potential advantage of using ammonia as a fuel?

A) High energy density
B) Compatibility with existing infrastructure
C) Abundant availability of feedstocks
D) Easy storage and transportation

Show Answer

Explanation: The correct answer is B) Compatibility with existing infrastructure. A potential advantage of using ammonia as a fuel is its compatibility with existing infrastructure. Ammonia can be stored and transported similarly to conventional fuels, making it easier to integrate into existing fuel distribution systems. This compatibility can help facilitate the adoption of ammonia as a cleaner alternative fuel.
