...Department of Energy is funding seven research partnerships to test sequestration technologies. This summer, one of those projects will inject a modest 2,000 metric tons of CO2 into the sandstone subsurface beneath a spread of tomato fields near Thornton, Calif., where it would stay, in effect, forever...
...investigators involved in the Thornton project insist there is little cause for worry. "The fields held oil and gas for millennia," says Larry Myer, an earth scientist with Lawrence Berkeley National Laboratory in Berkeley, Calif., and the project's director, "so geologically we know they're going to hold CO2...
Even if researchers master the mechanics of sequestration, they must still develop a way to separate CO2 from power-plant exhaust so that there will be something to stash in the cavities in the first place. There are two promising methods. One is to gasify coal before it's burned, reducing it to a high-pressure synthetic gas that can be stripped of its carbon, leaving mostly hydrogen behind. The alternative is to pulverize coal as power-plant operators do now but then rely on new hardware to separate the CO2 after burning. Both methods are at least 20 years...
...easy to overlook how important a building like this one could be. While the power and auto industries get the bulk of the blame for the planet's carbon crisis, the business of operating office buildings and homes is responsible for 38% of U.S. CO2 emissions. In the case of offices, mid--20th century technology worked against us, as the development of low-temperature fluorescent lights and high-powered air conditioning made it possible to design sealed structures that you could drop into any climate. "It gave architects the power to design anything, then hand it over to engineers...
Estimated tons of additional CO2 emissions the "open skies" deal would create annually. Weeks before agreeing to the airline deal, European leaders had pledged to cut overall greenhouse-gas emissions...
