I'd bet that the E, F, H, or whatever, could be deployed with or without XONON.

I am certain the E and F series can be deployed with Xonon. I am not absolutely certain the H series can without some further modification to the Xonon combustor to achieve the appropriate inlet temperatures and gas flow characteristics. Of course, any new turbine application requires specific modifications to Xonon to match the gas flows, etc. If the late-day sell-off on Friday was because GE did not mention Xonon for the new H series, people have not been paying attention to this market. First of all, the news GE released is nothing new. It has been known for months that this H series turbine would be deployed at the Sithe Power plant. While this is a commercial order, it is analogous to the Xonon order for Pastoria. While we are likely to see other deployments fairly soon, the Sithe plant will act as a bit of a testing ground.

As for no Xonon announcement with the H series, GE has not even officially begun offering Xonon for its E and F class turbines, as final refinements are made. To conclude the H cannot use Xonon is just wrong at this point. GE will offer many turbines with and without Xonon, based on specific NOx level needs of the buyers. If a particular buyer needs only 9 ppm, no Xonon. What will GE offer when power plant operators want new H series turbines in an area that requires < 3ppm for a new permit???????

Here is a little exerpt from the Department of Energy's site on the Advanced Turbine System project. Note, it mentions catalytic combustion as an option.

The emerging General Electric and Westinghouse utility ATS designs share the following features: Combustion System
The dry combustion system has can-annular combustors of lean premixed multi-stage design, resulting in single-digit NOx generation. Options to improve performance offered by this new design include catalytic combustion to reduce NOx, eliminating cooling air injection into the turbine path, and closed-loop steam cooling of the combustors and transitions.
