===Technology===
Original FutureGen project was intended to combine and test several new technologies in a single location, including [[Coal#Gasification|coal gasification]], emissions controls, [[hydrogen production]], electricity generation, and [[Carbon capture and storage|carbon dioxide capture and storage]] (CCS).<ref>{{cite web |url=http://www.futuregenalliance.org/technology.stm |title=FutureGen - Technology |access-date=2008-01-04 |url-status=dead |archive-url=https://web.archive.org/web/20080101033603/http://www.futuregenalliance.org/technology.stm |archive-date=2008-01-01 }} FutureGen Technology Overview</ref>

[[Integrated Gasification Combined Cycle]] (IGCC) was the core technology behind FutureGen. IGCC power plants use two turbines – a gas and a steam turbine – to produce electric power more efficiently than pulverized coal plants. IGCC plants also make it easier to capture carbon dioxide for carbon sequestration.<ref>{{cite web |url=http://www.futuregenalliance.org/technology/coal.stm |title=FutureGen - Coal Gasification |access-date=2008-01-21 |url-status=dead |archive-url=https://web.archive.org/web/20080113072754/http://www.futuregenalliance.org/technology/coal.stm |archive-date=2008-01-13 }} Coal Gassification</ref>

FutureGen was to capture carbon dioxide produced during the gasification process and pump it into deep rock formations thousands of feet under ground. FutureGen specifically targeted rock formations containing saline water, as these are one of the most abundant types of geologic formations that can be used to store carbon dioxide worldwide.<ref>{{cite web |url=http://www.futuregenalliance.org/technology/carbon.stm |title=FutureGen - Carbon Sequestration |access-date=2008-01-21 |url-status=dead |archive-url=https://web.archive.org/web/20080112193255/http://www.futuregenalliance.org/technology/carbon.stm |archive-date=2008-01-12 }} Carbon Sequestration</ref> A study by the Global Energy Technology Strategy Program estimates the storage capacity of these saline rock formations in the U.S. to be 2,970 gigatons of carbon dioxide, compared to a capacity of 77 gigatons of carbon dioxide for all other types of reservoirs, such as depleted gas fields.<ref>“Carbon Dioxide Capture and Geologic Storage: A Core Element of A Global Energy Technology Strategy To Address Climate Change, p. 26. {{cite web |url=http://www.pnl.gov/gtsp/docs/gtsp_reportfinal_2006.pdf |title=Archived copy |access-date=2008-02-02 |url-status=dead |archive-url=https://web.archive.org/web/20080216073055/http://www.pnl.gov/gtsp/docs/gtsp_reportfinal_2006.pdf |archive-date=2008-02-16 }}</ref> Focusing on rock formations with saline water was intended to help ensure that the lessons learned from the project are broadly transferable throughout the U.S. and around the world.
