High hydrogen content fuels can be used in gas turbine for power generation with CO 2
capture, IGCC plants or with hydrogen from renewables. The challenge for the engine is the
high reactive combustion properties making dilution necessary to mitigate NOx emissions at
the expense of a significant energy cost. In the concept analysed in this study, high Exhaust
Gas Recirculation (EGR) rate is applied to the gas turbine to generate oxygen depleted air.
As a result combustion temperature is inherently limited, keeping NOx emissions low without …

A novel gas turbine cycle concept applicable to power plants with pre-combustion CO 2
capture or integrated gasification combined cycle (IGCC) is presented. These power plants
use a hydrogen rich fuel with high reactive combustion properties which makes fuel dilution
necessary to achieve low NOx emissions. The proposed novel gas turbine arrangement is
set up as to avoid both fuel dilution and its consequent efficiency penalty, and breakthrough
in low NOx combustion technology. In this concept, a high exhaust gas recirculation (EGR) …
