Environmental impact of the energy industry to virtually all aspects of present society, especially for transportation and heating for both homes and for commercial activities. Natural gas is often described as the cleanest fossil fuel, producing less carbon dioxide per joule delivered than either coal or oil., and far fewer pollutants than other fossil fuels. However, in absolute terms it does contribute substantially to global carbon emissions, and this contribution is projected to grow. According to the IPCC Fourth Assessment Report, in 2004 natural gas produced about 5,300 Mt/yr of CO emissions, while coal and oil produced 10,600 and 10,200 respectively (Figure 4.4); but by 2030,
Electricity sector in India 100 MMSCMD. The break even price for switching from imported coal to LNG in electricity generation is estimated near 6 US$/mmBtu. Indian government has taken steps to enhance the generation from the stranded gas based power plants for meeting peak load demand by waiving applicable import duties and taxes due to drastic fall in the LNG and crude oil international prices. Gasification of coal or lignite or pet coke or biomass, produces syngas or coal gas or wood gas which is a mixture of hydrogen, carbon monoxide and carbon dioxide gases. Coal gas can be converted into synthetic natural gas
