What is 鈥渃lean coal?
鈥淐lean coal鈥?usually means capturing carbon emissions from burning coal and storing them in underground pockets of porous rock. While carbon capture and storage (CCS) technically does work, it is expensive to build new infrastructure and retrofit old plants. There are other dangers associated with burning coal, too.
Is coal bad for the environment?
That鈥檚 okay, because, neither does clean coal. Coal is the most carbon-rich fuel we have, and when it comes to the amount of climate-killing carbon dioxide it puts into the atmosphere, it鈥檚 filthy. Here鈥檚 how many pounds of CO2 our various fuels generate per million Btu units of energy produced, from greatest to least.
Can Co-coal ever be clean enough?
Coal-the dirtiest fossil fuel-can never be truly clean. But by capturing the carbon dioxide released by burning it, proponents of the energy say it can be clean enough to meet the large global demand for coal without severely impacting the environment.
Is it possible to capture carbon dioxide from coal gasification?
Capture of carbon dioxide from coal gasification is already achieved at low marginal cost in some plants. One (albeit where the high capital cost has been largely written off) is the Great Plains Synfuels Plant in North Dakota, where 6 million tonnes of lignite is gasified each year to produce clean synthetic natural gas.
