Hydrogen-Enriched Turbines
Program Goals
- Develop advanced combustion capabilities for H2 in gas turbine applications
Drivers
- H2 and H2-enriched hydrocarbon fuels allow stable combustion at the low temperatures needed to minimize NOx
- H2-blend approach provides solution to contemporary problems and provides a transition strategy to a carbon-free H2 energy system.
- Alternative low- and medium-heating value fuels containing H2 could provide a significant source of cost-effective fuels.
- Gas turbines are the fastest growing power production technology.
- Gas turbines are responsible for about 15% of the U.S. CO2 budget and are anticipated to grow to 28% in the next 20 years.
Collaborations
- We have working collaborations with GE Aircraft Engines, Pratt Whitney, National Energy Technology Laboratory (NETL) and NASA to develop H2 and H2-enriched gas turbine.
- Collaborations with GE and Goodrich to identify problematic areas related to gas turbines and demonstrate merits of H2 enrichment.
IEA Collaboration
- A subcommittee has been established to identify areas for collaborative research. The use of gas turbines in “zero-emission„ H2 applications was identified as a primary program focus.
- An administrative framework has been established. Technical and Strategy Committee members were selected with Sandia co-chairs on each.

Economic Analysis
- Cost comparisons with dry low NOx combustors and selective catalytic reduction showed 15% H2 addition cost competitive.
- Less than 3 ppm NOx achievable with 15% H2 addition
- H2 addition up to 20% offers NOx levels below 1 ppm and reduced CO2 emissions.
