Turbine systems and components targeted for improvement include combustor technology, materials research, enhanced cooling technology, and coatings development. These technologies are considered key components of FutureGen, which will use technology developed from the core R&D program, including Advanced Turbines, to build and operate the world’s first near-zero emissions power plant that will produce electricity and hydrogen from coal while capturing and storing CO2 through sequestration. It is intended that the successful prototype would be a model for other near-zero emission coal plants that can produce electricity at no more than a 10 percent increase in cost over a conventional plant, and produce hydrogen at $4/million Btu (wholesale).
By 2010 (on syngas):
- Reduce NOx emissions to 2 ppm in the turbine exhaust at 15 percent oxygen.
- Contribute to increasing power block efficiency by 2–3 percentage points over baseline (the performance currently achieved by the F-frame turbines at the Tampa Electric and Wabash River IGCC facilities).
- Contribute to reducing the capital costs of a CC power island by 20–30 percent over the previously established baseline.
By 2012 (on hydrogen with carbon capture):
- Develop a turbine fueled with hydrogen that facilitates integration with coal-based IGCC power plants designed for CO2 capture and sequestration.
- Demonstrate fuel flexibility, allowing for turbine operation on conventional syngas or 100 percent hydrogen (on a heat input basis).
- Develop emissions control technology capable of reducing NOx emissions to near-zero.
