NTPC to set up 100Mw ‘green’ power plant
National Thermal Power Corporation plans to set up a 100Mw green power plant that will run on synthesis gas (coal turned into gas) and plans to finalise consultants for the project by the end of this year. The plant will be based on Integrated gasification combined cycle (IGCC), which creates less pollution and has higher efficiency compared to conventional coal.
The project is part of NTPC’s cleaner coal drive. The technology turns coal into syngas (or synthesis gas) and removes impurities from it before it is combusted. The emerging clean coal technology is gaining importance, as coal-based thermal power plants are heavily polluting.
The 100-Mw thermal power generation project based on IGCC is aimed at adapting the new technology to Indian conditions.Low-ash content coal is a prerequisite for IGCC and the technology has proved quite effective in countires where the ash content in coal is low (up to 10 per cent).
However according to industry experts, the technology needs to be developed further to use it in the Indian scenario where ash content in coal varies between 35-40%.
