A $20 million incentive from XPRIZE aims to convert carbon dioxide emissions from power plants into useable products such as enhanced concrete, biofuels, nanotubes, toothpaste, fish food or fertilizer, among others.
The organization, which organizes and manages a range of incentive competitions designed to help solve problems, has selected 27 teams to advance to the semi-final portion of the NRG COSIA Carbon XPRIZE.
The teams, which are listed on the XPRIZE site, include 12 teams working with coal and 21 working with natural gas. Six teams work with both. These teams include carbon capture technology companies, academic institutes, non-profits and new startups.
The next step is for teams to demonstrate their technology at a pilot scale using either real flue gas or simulated flue gas. Over the next 10 months, teams must meet minimum requirements and will be scored on how much carbon they can convert and the net value of their products.
Five winners will be selected, and they’ll share $2.5 million and move onto the finals of the competition.
Finals will have the teams demonstrating their technology under real-world conditions at a larger scale. Coal teams will work at the Wyoming Integrated Test Center in Gillette, Wyoming, while natural gas teams will test at an unannounced natural gas power plant in Alberta.
