GreenGen and GoodSpring are based on the TPRI technology so they have some common traits that are unique in the industry. Record setting levels of cleanliness in acid rain causing gasses, mercury, and particulates should allow both facilities to reduce those major emissions by about 99% or greater when compared to the average coal power plant in the USA.

What’s the time table for Good Spring and GreenGen as IGCC facilities with CO2 handling capabilities?
GreenGen commenced design in 2004 and is currently under construction. GreenGen will likely begin offering electricity in mid 2011. Good Spring IGCC hopes to break ground sometime in the Summer of 2010 and begin producing power in 2013.
Can companies in the USA and China really work effectively on Climate related matters?
The cooperation between the two countries must work. If the leading emitters of greenhouse gases fail to take leadership, it will be difficult to expect others to follow. We have found Huaneng to be a focused and engaged party intent on showing commercial-scale results. Both companies have committed to staffing people at one another’s offices in China and the USA to ensure communications and progress happens in a coordinated and timely manner. There is no time for pageantry and nice-sounding talk.
What kinds of expertise do the parties bring to this relationship?
We evaluated many IGCC technologies and found the technology from TPRI being used at GreenGen was the most efficient for a commercial-scale project. In exchange for information on how to best implement the IGCC technology from GreenGen, we will provide post-gasification clean-up technologies. These technologies should easily make Good Spring IGCC the lowest emission plant of it’s kind and allow GreenGen to be as clean as possible and similar to Good Spring IGCC in areas of particulate, SOx, NOx, mercury, and CO2 emissions.
How do you propose to sequester the CO2?
We chose Pennsylvania in large part because the geology is favorable for CO2 sequestration. The State also has plans for a pipeline network and central sink (storage). We are heavily in favor of the Statewide network because many utilities could use such a system over time. However, if the State cannot construct such a system for any reason, we have sites nearby and even directly underneath our plant. We plan to liquefy the CO2 and pump it underground into sandstone formations so that the CO2 will bind with calcium and become a solid which would not likely seep out. We can sequester about half our CO2 at startup and move towards 90% over 5 years of operation. This means we could meet EPACT stated goals about 10 years ahead of schedule.
What happens next if all goes well?
If this first project goes well, we intend to construct several similar projects in the same area. Our analysis shows that the PJM electricity grid is facing an aging infrastructure of suppliers and a lack of significant and cleaner sources. Combined with rate caps that expire in 2010 and increasing alternative energy portfolio requirements in the State of Pennsylvania, the market is very attractive for us to invest into for a long period of time.
Please outline some of the innovative features envisioned for the GreenGen (Tianjin, China) and GoodSpring (Good Spring, PA) Clean Coal Power Plants?
