Notice of Centennial Challenges CO2 Conversion Challenge.
Phase 2 of the CO2 Conversion Challenge is open, and teams that wish to compete may now register. Centennial Challenges is a program of prize competitions to stimulate innovation in technologies of interest and value to NASA and the nation. This competition has two phases with a total prize purse of up to $1 million. Phase 1 (completed in April 2019) was the Concept Phase with a prize purse of $250,000 awarded equality among the top five scoring teams. Teams were asked to demonstrate capabilities to develop technologies to manufacture “food” for microbial bioreactors from CO2 and hydrogen molecules, with the ultimate goal of producing glucose. Phase 2 is a Demonstration Challenge with a prize purse of up to $750,000. NASA is providing the prize purse, and NASA Centennial Challenges will be managing the Challenge with support from The Common Pool.
Challenge registration for Phase 2 opens September 19, 2019, and will remain open until 6:00 p.m. Eastern Time on November 30, 2019. Teams must submit their application by June 5, 2020. The competition will conclude in September.
Other important dates:
March 1-31, 2020—Optional Challenge Mid-Point Progress Updates Due
June 5, 2020—Application Deadline
September 2020—Winners Announced
The CO2 Conversion Challenge Phase 2 competitors will initially register and submit an application explaining components of their system and its operation virtually via electronic submissions. Upon review of a team's registration and eligibility, a judge will schedule a site visit to the team's laboratory to observe the successful operation of the system and collect a sample. The sample will then be collected and sent to an independent laboratory for analysis. Phase 2 will be executed at the participants' facility or lab.

Competitors are required to build, demonstrate and produce a product from a system that manufactures simple sugars for microbial bioreactors from CO2 and hydrogen molecules, with the ultimate goal of producing glucose.
Future planetary habitats on Mars will require a high degree of self-sufficiency. This requires a concerted effort to both effectively recycle supplies brought from Earth and use local resources such as CO2, water and regolith to manufacture mission-relevant products. Human life support and habitation systems will treat wastewater to make drinking water, recover oxygen from CO2, convert solid wastes to useable products, grow food, and specially design equipment and develop equipment packaging to allow reuse in alternate forms. In addition, In-Situ resource utilization (ISRU) techniques will use available local materials to generate substantial quantities of products to supply life support needs, propellants and building materials, and support other In-Space manufacturing (ISM) activities.
Many of these required mission products such as food, nutrients, medicines, plastics, fuels, and adhesives are organic, and are comprised mostly of carbon, hydrogen, oxygen and nitrogen molecules. These molecules are readily available within the Martian atmosphere (CO2, N2) and surface water (H2 O), and could be used as the feedstock to produce an array of desired products. While some products will be most efficiently made using physicochemical methods or photosynthetic organisms such as plants and algae, many products may best be produced using heterotrophic (organic substrate utilizing) microbial production systems. Terrestrially, commercial heterotrophic bioreactor systems utilize fast growing microbes combined with high concentrations of readily metabolized organic substrates, such as sugars, to enable very rapid rates of bio-product generation.
The type of organic substrate used strongly affects the efficiency of the microbial system. For example, while an organism may be able to use simple organic compounds such as formate (1- carbon) and acetate (2-carbon), these “low-energy” substrates will typically result in poor growth. In order to maximize the rate of growth and reduce system size and mass, organic substrates that are rich in energy and carbon, such as sugars, are needed. Sugars such as D-Glucose, a six-carbon sugar that is used by a wide variety of model heterotrophic microbes, is typically the preferred organic substrate for commercial terrestrial microbial production systems and experimentation. There are a wide range of other compounds, such as less complex sugars and glycerol that could also support relatively rapid rates of growth.
To effectively employ microbial bio-manufacturing platforms on planetary bodies such as Mars, it is vital that the carbon substrates be made on-site using local materials. However, generating complex compounds like glucose on Mars presents an array of challenges. While sugar-based substrates are inexpensively made in bulk on Earth from plant biomass, this approach is currently not feasible in space. Alternatively, current physicochemical processes such as photo/electrochemical and thermal catalytic systems are able to make smaller organic compounds such as methane, formate, acetate and some alcohols from CO2; however, these systems have not been developed to make more complex organic molecules, such as sugars, primarily because of difficult technical challenges combined with the low cost of obtaining sugars from alternate methods on Earth. Novel research and development is required to create the physicochemical systems required to directly make more complex molecules from CO2 in space environments. It is hoped that advancements in the generation of suitable microbial substrates will spur interest in making complex organic compounds from CO2 that could also serve as feedstock molecules in traditional terrestrial chemical synthesis and manufacturing operations.Start Printed Page 49771
The CO2Conversion Challenge is devoted to fostering the development of CO2conversion systems that can effectively produce singular or multiple molecular compounds identified as desired microbial manufacturing ingredients and/or that provide a significant advancement of physicochemical CO2conversion for the production of useful molecules.
I. Prize Amounts
Phase 2 of the CO2 Conversion Challenge will award to up to three (3) top teams, who will receive prizes from a prize purse of $750,000 (seven-hundred fifty thousand dollars). Teams will be required to submit: (1) An application containing a description of the physiochemical conversion system they will build to demonstrate the production of carbon-based molecular compounds and (2) a video of the system in operation that clearly depicts the overall component and operation of the system. Upon completion of a phone interview with a judge, teams will be required to host a site visit by a judge where the operation of the system is demonstrated and a sample to be analyzed is produced and collected. The team's product will be examined using an independent chemical analysis to determine if any of the targeted compounds are present.
|Challenge targeted compounds||Weighting factor|
|Other 6-carbon sugars (D-hexoses)||80|
|5-carbon sugars (D-pentoses)||50|
|4-carbon sugars (D-tetroses)||10|
|3-carbon sugars (D-trioses)||5|
If enantiomers of the targeted compounds are present, the mass of each will be measured. The total score will be calculated by taking the mass of the most desired enantiomer “D” form minus the mass of the undesired “L” form. For example, if equal amounts of “D” and “L” glucose are found, then no points will be given for that compound.
The three highest scoring teams will be awarded the following prizes:
First place—$350,000 (three hundred fifty thousand U.S. dollars)
Second place—$200,000 (two hundred thousand U.S. dollars)
Third place—$100,000 (one hundred thousand U.S. dollars)
In the event of a tie score between two or more teams, the corresponding award(s) will be divided evenly among the teams. For example, a tie for first place will result in both teams receiving ($350,000 + $200,000)/2 = $275,000.
$100,000 bonus prizes awarded to as many three (3) teams.
Bonus Prize—System Effectiveness for Space Mission Applications: The information provided in the Demonstration Application as well as information gathered during the on-site judging event will be used by the judging panel to assess the overall system effectiveness for future application in space missions. A total of $100,000 will be available for bonus prizes in amounts determined by the judges for up to 3 teams. Teams do not need to win one of the contest prizes to be awarded a Bonus Prize. The top score will receive $50,000 and the next two highest scores will receive $25,000. A minimum score of 65 points is required to be eligible for a bonus prize.
