As part of its efforts to bring some parts of Tamil Nadu under the Compressed Natural Gas (CNG) ambit, GAIL (India) Ltd has proposed to set up a CNG corridor, consisting of Nagapattinam, Karaikkal, Puducherry, Tiruvarur, Ramanathapuram among other areas of the state, said UD Choubey, CMD of GAIL. GAIL Gas, a 100% subsidiary of GAIL will work out a suitable strategy in this regard. He said the plan is in initial stage and the company will consider exploiting the gas sources in these places at maximum level to supply as a fuel for the increasing demand from host of sectors in the state, he said. Given the growing fuel cost and the expected increase over the years, it is ideal to go for natural gas, which is more cleaner, cheaper and environment-friendly. It not only help utilising the gas optimally but will also help indutrialising the state in a big way, he said.
