North Dakota’s lignite coal industry is excited about a new technology that could drastically cut down on carbon dioxide emissions from coal fired power plants.
It’s called the “Allam Cycle.”
"It would allow a power plant to take coal, gasify it, oxy-fire it at very high pressure," said Mike Jones, the vice-president for research and development with the Lignite Energy Council. "By oxy-firing it, we basically would be using a super-critical stream of CO2 as a working fluid that drives the turbine."
Jones says there are a number of reasons to do this.
