Cheyenne, Wyo. - Organizers of an international competition to turn greenhouse gases into useful products are making a final push for entries before next week's deadline.
The NRG COSIA Carbon XPRIZE will award $20 million to teams that can turn carbon dioxide emissions from coal- and gas-fired power plants into money-making products. Potential uses of the CO2 include graphene, a material stronger than steel.
Paul Bunje with XPRIZE says 15 teams have formally registered. Many others have expressed interest. Entrants so far include corporations, academics and startup companies.
Formal entries are due July 15. Teams that pass the first two rounds of competition will get to demonstrate their ideas at a coal-fired power plant near Gillette.
The contest also will take place at a gas-fired power plant in Alberta, Canada.
