Q22. 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 an 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 rise ecological and social concerns
Select the correct answer using the codes given below
a) 1 and 2 only
b) 2 and 3 only
c) 3 only
d) 1, 2 and 3
The correct answer is 2 and 3 only.
- Algae-based biofuels
- It can be produced on land, in saline water, or wastewater. Hence, Statement 1 is not correct.
- Algal biofuel production is possible in both seas and on land.
- They can grow in marginal or non-cropland environments, as well as brackish or polluted water.
- Land-based systems have advanced more than sea-based systems. Because producing biofuels from algae is still in the pre-commercial stage of technology development, and capital investments are a significant barrier, setting up and engineering the algae-based biofuel production requires a high level of expertise/technology until the construction is completed. Hence, Statement 2 is correct.
- Economically viable production necessitates the establishment of large-scale facilities, which may raise ecological and social concerns because it reduces the amount of food available for humans and increases the cost of food and fuel due to supply shortages. Hence, Statement 3 is correct.
