Though LNG based power plant can entirely eliminate the pollution level because of proper combustion of the gas. However, we must look into the constraints associated with its usage. The following points should be looked into -
1) At present, we don't have huge stock of this Liquified Natural Gas and as such this material needs to be imported from South Arabia, Iran, Qatar etc at a sorbitant price and hence the final product, ie the power generated per unit has to sold at a very expensive price. In such a case, the customers would like to switch other options.
2) Since feeding this gas would be a continious affair and hence a large storage area is required to be made. At present we do have different terminals such as Cochin, Kakinada, Ennore etc.
3) The behaviour of the International market is erratic and in future, the price of this product may escalate further causing a heavy pay out by way of import price.
However, we must carry out geological explorations to locate more basins so that we may curtail the use this fuel considerably by means of import and power generation with LNG can be conveniently commissioned.
We must encourage the usage of wind - energy, solar - panels wherever possible and further installation of Atomic Power Generation would solve our scarcity in terms of power generation.
Coal - based power plant has its inherent defect the chief being emission of obnoxious gases through the chimney apart from large handling of ashes making the land infertile in its adjoining area. At the same time, rate of depletion of the same is very fast and as such we need to switch over this fuel.
