The Three Competing Ways to Capture Carbon Dioxide

Pre-combustion is a big process. It's already in use actually for natural gas. They've already been using this. The good thing about post-combustions is you can run around the country and retrofit old power plant to capture carbon dioxide. Pre-combustION, you pretty much have to build that in as you're building a new power plant. And then the last one is oxy fuel combustion. Oxy fuels it like 90 percent of the carbon dioxide. So those are pretty much the three competing ways to capture carbon emissions right now.
