Q1 What is an aerobic digestion? 2
Aerobic digestion is the process of creating an oxygenated environment, which with the
A-1 addition of microorganisms, naturally breaks down food waste over a short period of time
into water that can be discharged via existing drainage systems.
Q2 Define fermentation in biomass energy? 2
A-2 Fermentation is an anaerobic process that breaks down the glucose within organic
materials. It is a series of chemical reactions that convert sugars to alcohol or acid. Yeast or
bacteria are added to the biomass material, which feed on the sugars to produce ethanol
and carbon dioxide.
Q3 What is OTEC? Discuss in brief. 2
A-3 Refer to class notes
Q4 How are tides generated? 2
A-4 Refer to class notes
Q5 What are the advantages of tidal power? 2
A-5 1) It is an inexhaustible source of energy.
2) Tidal energy is environment friendly energy and doesn't produce greenhouse gases.
3) As 71% of Earth's surface is covered by water, there is scope to generate this energy
on large scale.
4) We can predict the rise and fall of tides as they follow cyclic fashion.
Explain the process of gasification of solid biomass. What is thegeneral composition of
Q6 the gas produced and what is its heating value? What are its applications? 10
