Given below are the names of four energy crops. Which one of them can be cultivated for ethanol?
Correct Answer:
(B) Maize
Maize is cultivated for ethanol while Jatropha, Pongamia and Sunflower are cultivated for biodiesel.
Ques: 2
The major component of CNG is:
Correct Answer:
(D)
CH4
The use of diesel and petrol as fuels in automobiles is being replaced by CNG (Compressed Natural Gas), because CNG produces the harmful products in very small amounts. The major component of CNG is Methane (CH4).
Ques: 3
It is possible to produce algae-based biofuels, but what is/are the likely limitations of developing countries in promoting this industry?
Production of algae-based biofuels is possible in seas only and not on continents.
Setting up and engineering the algae-based biofuel production requires a high level of expertise/ technology until the construction is completed.
Economically viable production necessitates the setting up of large scale facilities which may raise ecological and social concerns.
Select the correct answer using codes given below:
Correct Answer:
(B) 2 and 3 only
The production of algae-based biofuel is possible in both seas and continents. Thus, statement (1) is incorrect. The high level of expertise is required for the production and engineering of these fuels, as well as knowledge and experience are required for higher production and innovation. It is difficult to produce such type of fuel in developing countries because it requires heavy capital investment, apart from this, establishing facilities for large scale production, ecology and society can be adversely affected.
Ques: 4
Consider the following statements regarding Green Fuels Alliance India (GFAI):
1. It was introduced by India in collaboration with Denmark.
2. It aims to advance the green fuels sector, including green hydrogen, through innovation and partnerships.
Which of the statements given above is/are correct?
Correct Answer:
(B) 2 only
Denmark has introduced the Green Fuels Alliance India (GFAI) to enhance collaboration with India in the sustainable energy sector, aligning with both nations’ goals of achieving carbon neutrality.
It aims to advance the green fuels sector, including green hydrogen, through innovation and partnerships. GFAI’s objective is to foster an ecosystem promoting sustainable energy growth in India, involving businesses, government entities, and research institutions.
Ques: 5
Consider the following statements regarding Bioethanol:
1. It is derived from vegetable oils like soybean oil or palm oil, vegetable waste oils, and animal fats.
2. A litre of ethanol contains approximately two thirds of the energy provided by a litre of petrol.
Which of the statements given above is/are correct?
Correct Answer:
(B) 2 only
Bioethanol
It is derived from corn and sugarcane using the fermentation process.
A litre of ethanol contains approximately two thirds of the energy provided by a litre of petrol.
When mixed with petrol, it improves the combustion performance and lowers the emissions of carbon monoxide and sulphur oxide.
Biodiesel
It is derived from vegetable oils like soybean oil or palm oil, vegetable waste oils, and animal fats by a biochemical process called “Transesterification.”
It produces very less or no amount of harmful gases as compared to diesel.
