Carbon credit
Unit 1 1
, A carbon credit is a tradable permit or certificate that provides the holder of
the credit the right to emit one ton of carbon dioxide or an equivalent of
another greenhouse gas.
The main goal for the creation of carbon credits is the reduction of emissions
of carbon dioxide and other greenhouse gases from industrial activities to
reduce the effects of global warming.
Significance
minimization of greenhouse gases emission
authorities set the caps on greenhouse gas emissions
companies need to purchase additional carbon credit when doing more
emission
those doing less carbon offset are awarded
Load Shedding
Load shedding is when power companies reduce electricity consumption by
switching off the power supply to groups of customers because the entire
system is at risk.
This could be because there is a shortage of electricity supply, or to prevent
transmission and distribution lines from becoming overloaded.
A number of factors can result in load shedding, including extreme weather
and infrastructure outages.
Coal Beneficiation
Coal beneficiation is the process of improving the calorific value of the coal
by removing the impurities or reducing the ash content.
This helps the power plants to generate a lesser amount of
fly ash, which is harmful to the environment.
Can be done in two stages
1. Mining Stage
removal of stones arid
2. Post Mining stage
Dry Method - crushing
Wet Method - washing
Unit 1 2
, Flow of process
ENVIRONMENTAL BENEFITS OF COAL BENEFICIATION
REDUCTION IN CARBON DIOXIDE EMISSIONS
REDUCTION IN OTHER POLLUTANTS
REDUCTION IN ASH HANDLING
Benefits
Plant operation cost decreases
Present Scenario of power generation in India
India’s energy sector stands-out amongst the most classified power sector in
the world.
Generation of energy extends from conventional sources, for example, coal,
hydro, gaseous petrol, oil, lignite and atomic energy to reasonable non-
conventional sources, for example, wind, sunlight based, and household
& agricultural wastages.
At present installed generation capacity of India is around 4,00,000 MW as
on 31 March 2022.
As of 31 march 2022, 59% of energy generated is from use of fossil (Coal,
Gas, diesel) and 39% by renewable sources (hydro, wind, solar, waste
energy) and around 2% by nuclear energy.
