Researchers at a variety of companies are working on using carbon as an ingredient in a range of products including concrete, biofuel—even food. Carbon capture and storage is seen as having failed in the U.S., in part because of high costs, says Marcius Extavour, technical operations director for the Carbon XPrize. Efforts at carbon capture and storage have largely stalled in the U.S., as big utilities have switched from coal to cheap and cleaner-burning natural gas and renewable power. Southern Co.’s Kemper County coal plant in Mississippi has a carbon capture and storage component. NRG earlier this year unveiled a much smaller, $1 billion capture and storage effort at its Parish coal plant near Houston.
