RE: Coal Gasification question



Sarah—

 

Most of what I’ve seen is from DOE.  The following paper seemed pretty comprehensive although I don’t recall if it covers CO2 sequestration.

 

J. Ratafia-Brown, L. Manfredo, J. Hoffman, and M. Ramezan, Major Environmental Aspects of Gasification-Based Power Generation Technologies, U.S. DOE NETL (December 2002) http://www.netl.doe.gov/coal/gasification/pubs/pdf/final%20env.pdf

It covers air emissions, water consumption, wastewater, and solid wastes/by-products, including comparison with pulverized coal and fluidized bed combustion in some cases. It does not suggest that coal gasification will yield zero emissions.

 

Also EM, the magazine of the Air & Waste Management Association, had a series of articles on coal gasification and IGCC (integrated gasification combined cycle) technology in its December 2004 issue.

·         “Integrated Gasification Combined Cycle (IGCC) Power Plants: An Introduction”

·         “IGCC Technology: Status, Opportunities, and Issues” by Neville A.H. Holt

·         “The Case for Gasification” by Gary J. Steigel and Massood Ramezan

·         “Stimulating Near-Term IGCC Deployment with 3Party Covenant Financing” by William G. Rosenberg, Dwight C. Alpern, and Michael R. Walker

I hope this is useful.

Subject: Coal Gasification question

 

Hello,

 

Does anyone have any information on the potential impact and/or emissions from a coal gasification plant that would also provide CO2 sequestration?  The DOE is presenting this technology as the pollution free power plant of the future (see http://www.fe.doe.gov/news/techlines/2003/tl_futuregen1.html or read short article below).  The project name is FutureGen - "a $1 billion DOE venture that will combine electricity and hydrogen production with the virtual total elimination of harmful emissions, including greenhouse gases."

 

Too good to be true?  There are some concerned communities that would like to know more.

FutureGen is an initiative to build the world's first integrated sequestration and hydrogen production research power plant. The $1 billion dollar project is intended to create the world's first zero-emissions fossil fuel plant. When operational, the prototype will be the cleanest fossil fuel fired power plant in the world.

The initiative is a response to President Bush's directive to draw upon the best scientific research to address the issue of global climate change. The production of hydrogen will support the President's call to create a hydrogen economy and fuel pollution free vehicles; and the use of coal will help ensure America's energy security by developing technologies that utilize a plentiful domestic resource.

Additionally, other countries will be invited to participate in the demonstration project through the Carbon Sequestration Leadership Forum and other mechanisms.

The prototype plant will establish the technical and economic feasibility of producing electricity and hydrogen from coal (the lowest cost and most abundant domestic energy resource), while capturing and sequestering the carbon dioxide generated in the process. The initiative will be a government/industry partnership to pursue an innovative 'showcase' project focused on the design, construction and operation of a technically cutting-edge power plant that is intended to eliminate environmental concerns associated with coal utilization. This will be a 'living prototype' with future technology innovations incorporated into the design as needed.

The project will employ coal gasification technology integrated with combined cycle electricity generation and the sequestration of carbon dioxide emissions. The project will be supported by the ongoing coal research program, which will also be the principal source of technology for the prototype. The project will require 10 years to complete and will be led by an industrial consortium representing the coal and power industries, with the project results being shared among all participants, and industry as a whole.

In the operational phase, the project will generate revenue streams from the sales of electricity, hydrogen and carbon dioxide. The revenue will be shared among the project participants (including the U.S. Government) in proportion to their respective cost-sharing percentage.
