The aim of this project was to demonstrate that a new approach to energy produced by oxyfuel could significantly reduce coal's enormous carbon footprint. The school built a closed-loop chemical reactor that circulates its components in a continuous cycle. To demonstrate its effectiveness, the school conducted an experiment using the reactor and coal. First, tiny iron oxide beads were used to manage the oxygen supply to the coal particles. The beads then entered the reactor chamber and were oxidized and reacted with the carbon particles to create carbon dioxide. The carbon dioxide then bubbled up and was captured as the beads flowed to a second area where the airflow reoxygenated the beads. The newly oxidized beads were then rolled back to the beginning and the process was repeated. In principle, OSU's closed-loop chemical reactor should be more efficient to operate than traditional oxyfuel reactors, which rely on energy-hungry air separation units for their oxygen supply. This experiment is important because it not only maintains a 90% carbon capture rate, but is also 35% less expensive than average carbon capture facilities (Coelho, 2010, p..
