NTPC Hydrogen co-firing feasibility demonstration
NTPC Ltd. and GE Gas Power are looking at hydrogen (H2) co-firing blended with natural gas in GE’s 9E gas turbines installed at NTPC’s Kawas combined-cycle gas power plant in Gujarat, India. The two companies are exploring further implementation at scale across NTPC’s installed units. The plant is powered by four GE 9E gas turbines operating in a combined-cycle mode and has an installed capacity of 645 MW. The E-class can burn up to 100% hydrogen by volume.
This capability varies depending on the type of combustion system used. For fuels with over 5% hydrogen by volume, gas turbine accessories need to be evaluated and possibly modified to reliably deliver the fuel to the combustors. A pilot project for 5% co-firing of hydrogen may be implemented at the Kawas gas power plant, based on the feasibility report.
