American Coalition for Clean Coal Electricity (ACCCE) is a coal-industry trade association working to increase the longevity of the coal industry. The association is comprised of coal industry companies and utilities that burn coal for power production.

What are Clean Coal Technologies? Clean Coal Technologies (CCTs) use coal for power generation in more environmentally acceptable and economically viable ways. They include processes that can be applied before, during and after utilisation.

Anthracite coal is considered "Clean" and has 92-98% Carbon content, whereas bituminous, sub-bituminous, and lignite coal have increasingly high impurity. Burning lower C-content coals (like lignite) would release a LOT of non-carbon into the air, including sulfur, which makes it "dirty".

CCS technology sends the syngas to a shift reactor, where it encounters steam. That steam transforms the carbon monoxide that's present into hydrogen and even more CO2. The CO2 is then captured from the gas stream, compressed, and dehydrated. That leaves it ready for transport and storage.

The Energy Future Coalition is a nonpartisan public policy initiative that seeks to speed the transition to a new energy economy. The Coalition brings together business, labor, and environmental groups to identify new directions in energy policy with broad political support. Energy Future Coalition. Formation.

ACE was formed in 1988 to bring together a wide range of groups in support of ethanol. Part of its mission is to unite agricultural producers, commodity and farm organizations, ethanol producers, rural electric cooperatives, businesses, and individuals.

An added benefit of coal cleaning is that several trace elements, including antimony, arsenic, cobalt, mercury, and selenium, are generally associated with pyritic sulfur in raw coal, and they too are reduced through the cleaning process.

Almost all coal plants operating today use “pulverized coal” (PC) technology, which involves grinding the coal, burning it to make steam, and running the steam through a turbine to generate electricity.

After years of development, the current clean coal technologies based on the partial gasification in foreign countries mainly are gasification combined with combustion technology, combined cycle technology, and polygeneration technology.

Currently IGCC plants typically have a 45% thermal efficiency. Capture of carbon dioxide from coal gasification is already achieved at low marginal cost in some plants.

Low-NOx burners allow coal-fired plants to reduce nitrogen oxide emissions by up to 40%. Coupled with re-burning techniques NOx can be reduced 70% and selective catalytic reduction can clean up 90% of NOx emissions.

CCS involves the capture of carbon dioxide (CO2) emissions from industrial processes, such as steel and cement production, or from the burning of fossil fuels in power generation. This carbon is then transported from where it was produced, via ship or in a pipeline, and stored deep underground in geological formations.
