Limitations of algae-based biofuel production
Question
It is possible to produce algae based biofuels, but what is/are the likely limitation(s) of developing countries in promoting this industry?
Select the correct answer using the code given below:
- 1.
Production of algae based biofuels is possible in seas only and not on continents.
- 2.
Setting up and engineering the algae based biofuel production requires high level of expertise/technology until the construction is completed.
- 3.
Economically viable production necessitates the setting up of large scale facilities which may raise ecological and social concerns.
Options
1 and 2 only
2 and 3 only
3 only
1, 2 and 3
Explanation
Statement 1 is incorrect: Algae-based biofuels can be produced both in marine and freshwater systems, and even in closed terrestrial photobioreactors. It is not restricted to seas only. Statement 2 is correct: Algae cultivation technology requires significant technical expertise and sophisticated engineering systems for optimal production efficiency. Statement 3 is correct: Large-scale algae facilities require substantial land and water resources, which can create ecological concerns and potential social impacts on local communities. > KEY INSIGHT: The primary limitations for developing countries are technological/expertise barriers and the need for large-scale infrastructure investment, not geographical constraints. Answer: (b).
