The EPA has announced ambitious plans to limit carbon emissions from power plants, which may lead these plants to use carbon capture technology. The technology, in turn, would capture the carbon emissions, preventing them from getting into the atmosphere.
Carbon capture technology does exist, and it does work. But in the entire world, there is currently only one power plant that uses it at scale, The Boundary Dam Power Station in North America. For everyone else, the technology is just too expensive.
This may make it difficult for power plants to follow the EPA’s proposal. There are two big factors. One is that the technology has to scale, and the other is that the carbon has to be stored.
