The electric power sector in much of the world has made significant strides in cutting carbon emissions, largely through increased use of renewables such as wind and solar, and a shift from coal to natural gas-fired power generation. Gas turbine industry attention is now directed at accelerating technology development and demonstration of “hydrogen readiness”, or the ability to burn hydrogen as a carbon-free replacement fuel for natural gas, while still maintaining low NOx emissions.
During a webinar presentation earlier this year, Siemens reviewed scope, timing and goals for its hydrogen technology development and demonstration projects. Near-term projects:
- 10 MW SGT-400. A commercial dry low emissions unit is being modified to operate initially in 2021 on a hydrogen and natural gas fuel blend with an incremental build up to 100% hydrogen.
- 24 MW SGT-600. Two DLE gas turbines tested in 2019 on mixtures of up to 60% hydrogen by volume while maintaining 25 ppm NOx emissions are expected to begin commercial operation in 2021.
- 33 MW SGT-700. Developmental hydrogen burner design based on additive manufacturing technology was tested on 100% hydrogen in 2019 while maintaining fairly low NOx emissions.
- 48 MW SGT-800. Full engine sector testing in 2020 with a hydrogen-fed array of 5 burners (out of 30 burners) operating on 75% by volume hydrogen and 40 ppm NOx emissions.
