A Better Way To Capture Carbon
From MIT’s Technology Review:
Researchers have developed porous materials that can soak up 80 times their volume of carbon dioxide, offering the tantalizing possibility that the greenhouse gas could be cheaply scrubbed from power-plant smokestacks. After the carbon dioxide has been absorbed by the new materials, it could be released through pressure changes, compressed, and, finally, pumped underground for long-term storage.
Such carbon dioxide capture and sequestration could be essential to reducing greenhouse-gas emissions, especially in countries such as the United States that depend heavily on coal for electricity. The first stage, capturing the carbon, is particularly important, since it can account for 75 percent of the total costs, according to the Department of Energy.
