I have been very busy and have not had time to post or read others’ blogs. Sorry ’bout that.
Clean coal technology aims to permanently capture and isolate carbon dioxide gas resulting from coal combustion so that it does not
contribute to global warming. The most promising method of sequestering carbon dioxide is carbon capture and storage. The coal must
undergo gasification to remove the carbon dioxide before combustion. In this process, the coal is exposed to steam at high pressures and
temperatures, producing syngas, a mixture of carbon monoxide, carbon dioxide, hydrogen gas, and methane. This syngas then reacts
with chemical scrubbers which isolate and capture the carbon dioxide. This captured carbon dioxide is then transported and injected into
either underground or ocean waters. Unfortunately, clean coal does not exist. There are far too many environmental and economic
problems associated with the burning of coal, whether it be considered conventional or clean.
