Co-gasification of coal-petcoke and biomass in the Puertollano IGCC power plant

- The Puertollano IGCC plant performance is not affected by 2-4% biomass in the feed.
- A 46% reduction of CO2 emissions is calculated for mixtures with 60% biomass.
- The net power decreases for increasing biomass content due to its lower LHV.
- The biomass price is crucial for making the mitigation cost sustainable.
