XPRIZE Projects Aim To Convert CO2 Emissions, But Skepticism Remains
The XPRIZE foundation exists to encourage particular innovations that might be useful but from which conventional financial backers are likely to shy away. Previous X Prizes have been awarded for feats such as flying a reusable spacecraft to the edge of space, and designing cheap sensors to measure oceanic acidity. This week, the foundation announced a new prize. From a report: One pioneering team hopes to use carbon dioxide to make a stronger form of cement. Another wants to use carbon to make bioplastic. Still another is planning to transform CO2 into solid carbonates that can be used as building materials. The XPRIZE Foundation unveiled 10 teams yesterday as finalists in its $20 million contest to find a solution to carbon emissions. Its carbon competition is meant to find an economic use for planet-warming emissions. The basic idea: If emissions can be turned into a product, power companies will have an incentive to capture and sell carbon instead of releasing it into the atmosphere. A group of 47 teams from across the world initially submitted proposals. The remaining 10 teams will compete in two groups. One will test their technologies at a coal-fired power plant in Gillette, Wyo. The other will compete at a natural gas plant in Calgary, Alberta. Winners will be announced in 2020. They will split the $20 million purse. [...] Significant skepticism over carbon utilization's effectiveness persists, however. The chief concern is that global carbon emissions outweigh the market for carbon products. "There is no question you can do it. The question is whether it can be a meaningful contribution to climate mitigation," said Edward Rubin, a professor of environmental engineering at Carnegie Mellon University.Read more of this story at Slashdot.
