Limitations of algae-based biofuel production

S&TBiofuels and renewable energyStatement-basedMediumStatic

Question

It is possible to produce algae based biofuels, but what is/are the likely limitation(s) of developing countries in promoting this industry?

1Production of algae based biofuels is possible in seas only and not on continents.
2Setting up and engineering the algae based biofuel production requires high level of expertise/technology until the construction is completed.
3Economically 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:

  1. 1.

    Production of algae based biofuels is possible in seas only and not on continents.

  2. 2.

    Setting up and engineering the algae based biofuel production requires high level of expertise/technology until the construction is completed.

  3. 3.

    Economically viable production necessitates the setting up of large scale facilities which may raise ecological and social concerns.

Options

a

1 and 2 only

b

2 and 3 only

Answer
c

3 only

d

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).
