Press Release: 350Solutions Technology Verification Approach Vital in the $20M NRG COSIA Carbon XPRIZE

  • The firm designed and executed the verification protocol used to independently evaluate data from finalists which was critical to determining the competition’s winners
  • Signifies an industry shift toward increasing rigor and 3rd party assessment in evaluating low-carbon technologies critical to the net zero and carbon removal future

Raleigh, North Carolina (April 19, 2021) – 350Solutions has successfully completed their work as the official technology verification body of the NRG COSIA Carbon XPRIZE, with the winners of the five-year, carbon-future competition announced today. The firm’s role as independent verifiers for the $20M global competition included working with XPRIZE to establish the technically and environmentally focused verification protocols and metrics for each of the carbon utilization technologies in rounds two and three, as well as completing the independent verifications of each technology’s performance. 350Solutions’ efforts meant the competition’s judges received high-quality, vetted performance data for each of the nine finalists. Verified data from each technology’s operations was also used as inputs for life cycle analysis, economic assessment, and XPRIZE-specific scoring approaches. 

“As our best innovators and entrepreneurs develop and scale technologies and approaches to use or sequester carbon dioxide, we need to be sure we have high-quality, rigorous evaluations, including independent verification, so we have a sound understanding of the actual impact of each approach,” said Tim Hansen, Founder and CEO of 350Solutions. “Verification helps reduce risk for developers and investors while spurring continued innovation by providing credibility regarding a technology’s performance and impact.”

The team at 350Solutions brought more than 40 years of experience as independent environmental technology verifiers to their work within the competition.  350Solutions worked extensively with each of the finalists, designing verification procedures that were unique to each team because of the unique aspects, products, and processes of each technology, while staying within the rules, regulations, and needs of the larger XPRIZE competition. Each of the verifications included assessment of the amount of CO2 converted into a useful product, the energy and water consumption of the technology, and the overall net value of the final product.

“350Solutions played a critical role in the success of the NRG COSIA Carbon XPRIZE. Independent technical verification was a key requirement of the prize something we believe should be adopted industry wide for emerging cleantech such as carbon utilization,” said Michael Leitch, Technical Lead, NRG COSIA Carbon XPRIZE. “Their expertise across a wide variety of technical domains made them an ideal partner to verify the technologies of the Carbon XPRIZE finalists and semi-finalists.”
