Here's some evidence that proponents of coal-to-liquids are at least conscious of the problem and making an effort to address it: CO2 Sequestration Options for the Shenhua DCL Plant: A Pre-Feasibility Study April 1, 2007 Jerald J. Fletcher and Qingyun Sun West Virginia University The primary objective of this pre-feasibility study is to investigate and evaluate the technical and economic feasibility of carbon sequestration alternatives for the Shenhua Direct Coal Liquefaction (DCL) Plant in the Shendong coal mining area of Inner Mongolia. The larger objective is to identify and develop feasible, practical carbon management alternatives that can be implemented. Specific objects of this initial effort are to: (1) Develop a dialog between Chinese and American experts on carbon management, (2) Analyze the CO2 sequestration alternatives and related environmental problems for the DCL plant, and (3) Develop a plan for implementing a carbon sequestration option for the DCL plant. http://tiny.cc/g3m2J > >There's no guarantee of this that I've seen.

The "guarantee" you're looking for is approximated by laws and regulations that control air pollution emissions. There is currently a debate raging over whether there is an adequate legal basis for the regulation of CO2 emissions - the UN FCCC internationally and the Clean Air Act in the US. Those of us who wish to secure regulation of CO2 emission should work hard to get appropriate legislation passed. When CO2 emission reduction becomes the law of the land, the coal-to-liquid industry will have to comply. It is a fair bet that CCS technology - already demonstrated to be feasible at the Beulah, North Dakota coal gasification plant - will be the method by which carbon emissions are controlled by this industry. -dl --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups Global Change ("globalchange") newsgroup.
