This is an old article but it gives an idea of the fast happening industrial development in Gujarat. I found this on The Financial Express :
Public Sector oil exploration behemoth Oil and Natural Gas Corp Ltd (ONGC) is expected to start its pilot project for underground gasification of lignite near Vasthan area 20 kms away from Surat in Gujarat within a year. Not only that, the company has also identified three other sites in Bhavnagar district of Saurashtra for similar projects.
ONGC had entered into a MoU with the Gujarat government owned Gujarat Mineral Development Corp (GMDC) for underground gasification of lignite near Surat. ONGC has also identified three sites in Bhavnagar for studying the possibility for undertaking similar projects. Bhavnagar has a sizeable amount of lignite reserves and after the pilot project, the company will look at the three sites in Bhavnagar district for undertaking commercial production of natural gas through the gasification of lignite.
Lignite is a type of coal, and ONGC has identified around 20 odd coal mines for underground gasification of coal.
The project is expected to start by April 2008.
