Carbon capture has started at the 500 MW unit 13 of NTPC’s 4.8 GW Vindhyachal Super Thermal Power Station in Madhya Pradesh, India. The owner of the plant, NTPC selected the UK firms Carbon Clean and Green Power International to set up the carbon capture plant.
The plant is designed to capture 20 tonnes of CO2 per day, using a modified tertiary amine to capture CO2 from the flue gas. The CO2 will be combined with hydrogen to produce 10 tonnes per day of methanol through a catalytic hydrogenation process.
NTPC envisions that the project will comprise three parts: a carbon capture unit, a hydrogen generation unit that will use high temperature steam electrolysis (HTSE) to generate 3 tonnes per day of hydrogen, and a methanol production unit that will convert 10 tonnes per day of methanol from CO2.
Carbon Clean said that its CDRMax carbon capture technology can be used: “With point source gases that contain CO2 concentrations between 3-25 per cent by volume and produces CO2 with purities greater than 99 per cent which can then be sold, reused, or sequestered.”
