Coal

The coal-direct chemical looping (CDCL) process seeks to produce more energy, while also reducing emissions from energy production, specifically from coal-fired plants. Chemical looping uses oxygen carrier particles to convert carbon fuels while also capturing carbon dioxide. This is done in a two-step process, with one step involving the usage of these oxygen carrier particles to react with the coal, enabling combustion. The other part of the process involves recycling non-oxidized particles by allowing them to react with air, and then being allowed to react with coal once more. A demonstration of this has been performed, specifically with the collaboration of the Advanced Research Projects Agency. Coal-direct chemical looping is a unique type of chemical looping combustion that uses two reactors, one specifically for the reduction process and another for the combustion process.[1] [2]
