Biomass is the most common form of renewable energy. The cultivation and combustion of solid biomass, or the thermal utilization of sewage sludge is considered to decrease the net emissions of CO2
The type of biomass required is largely determined by the energy conversion process and the form in which the energy is required.
There are different types of biomass which could be used as energy source in power production:
(a) surplus and by-products from agricultural activities .e.g., straw,
(b) fast growing energy plants from reutilization of areas which become available by a necessary reduction of agricultural overproduction
(c) wood waste from forestry or wood processing.
In order to achieve a noticeable CO2 reduction, as well as fossil fuel substitution, it is desirable to use fairly large quantities of biomass for energy production. However, an exclusive biomass utilization would consequently lead to the construction of many decentralized plants, which is time-consuming and would require high financial investments as well as large storage capacities due to the seasonal fuel availability. Co-combustion, in contrast, is considered to be a cheap option for utilizing the existing biomass resources.
Keeping all the above points in mind
Develop a method for production of electricity using biomass that can make Indian villages self sufficient for their energy requirements. It should be cost effective, efficient and large scale.
Find out a substitute for gasoline used in vehicles using biomass.
Suggest methods to make some of the industries like pulp and paper self-sufficient for their energy requirements using biomass.
