Maybe I could just start by saying this is a relatively new field of research. Anybody who has coal is interested in it, so lots of countries are doing work right now in oxy-fuel and gasification and so on.
For instance, if this feed study from SaskPower allows them to go forward with that technology, that will be the first oxy-fuel clean coal power plant in the world. Although a lot of people are looking at it, it's brand new.
