An AAAS policy alert reports that "Coal state Senators Rockefeller (D-WV) and Voinovich (R-OH) have introduced the Carbon Capture and Storage Deployment Act of 2010 (S. 3589), which would invest $20 billion over the next ten years to develop carbon capture and storage (CCS) technology. The bill would support large-scale CCS pilot projects and establish a regulatory framework to monitor and govern long-term geological storage of carbon. The bill may be included in the Senate's climate and energy package."
Arizona gets a reported 36.4% of our electricity from burning coal (33.9% from natural gas, 23.6% from nuclear, and 5.8% from hydroelectric) as of last year [ref. America's Power] [right, coal-burning Navajo Generating Station near Page]
AZGS is participating in three projects to assess and characterize the potential for geologic sequestration of CO2 in Arizona.
