It is possible to produce algae based biofuels, but what is/are the likely limitation(s) 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 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 the code given below:
[UPSC Civil Services Exam – 2017 Prelims]
(a) 1 and 2 only
(b) 2 and 3 only
(c) 3 only
(d) 1, 2 and 3
Answer: (b)
Explanation:
- Algae-based biofuel can be produced using various sources such as land, saline water, and wastewater. Hence, statement 1 is incorrect.
- Algal biofuel can be produced in both marine and terrestrial environments. They can be cultivated on non-arable or marginal land, as well as brackish or contaminated water, but land-based systems are more advanced than sea-based ones.
- Creating and engineering algae-based biofuel production requires advanced technology and expertise because the technology is still in a pre-commercial stage, and capital investments represent a significant barrier. Hence, statement 2 is correct.
- Producing biofuel from algae on a large scale could create ecological and social concerns, such as reducing the amount of food available to humans and increasing food and fuel prices due to supply shortages. Hence, statement 3 is correct.
