About the Challenge


years running




in grants

Repsol Sinopec Brasil is pioneering carbon capture technology with the first pilot-scale Direct Air Capture (DAC) facilities in Latin America, to enable a path towards capture cost of €200 per ton of CO2.

DAC is a powerful tool in combating climate change, but current carbon adsorption materials face high energy demands, low efficiency, and high costs.

We invite startups and R&D institutes to propose innovative adsorbents that are efficient, scalable, and cost-effective.

Top 3 applicants will get to test their materials at PUCRS University’s DAC research facilities, from bench to prototype scale. The best-performing materials will move to field-scale testing (~15 tons/year).

Successful pilots can potentially lead to the exploration of collaboration opportunities.

Leverage Repsol Sinopec Brasil’s resources and expertise to advance DAC technology and create a cleaner future.

"We're thrilled to partner with SOSA to discover innovative solutions within the Bioeconomy. We're searching for startups developing groundbreaking applications in Forestry, Eucalyptus Biomass, Sustainable Packaging and Carbon Removal. If your venture fits the bill, we encourage you to apply!".

August 16th 2024

Selection criteria:

  • Technology:

DAC adsorption materials that undergo temperature-vacuum swing adsorption (TVSA) or vacuum-swing adsorption (VSA). Several classes of adsorbents are potentially promising for direct air capture including but not limited to amine-based sorbents, zeolites, and MOFs.

  • Development Stage:

Developed adsorbents that are already contacted in a form factor such as pellets, fibers, filters, monoliths or gel.

TRL ≥ 4 (Materials that have been tested at least in lab scale for the specific application)

  • Production Capacity:

The three finalists are required to supply material for prototype testing (up to 60g). The best performing material will will move to pilot-scale testing and will be required to provide the material for scale testing (up to 100 kg)

  • Conditions for participation:

Provide supporting documentation (isotherms, breakthrough testing, heat of adsorption, accelerated aging studies or literature references, etc) to your proposal that indicate the adsorbent you are developing meets the KPI criteria for the challenge.

  • Technical Criteria:
Working C02 Capacity
> 1 mmol/g
Contactor Pressure Drop
< 300 Pa
Material Lifetime
> 2 Years
Specific Energy Consumption
< 2000 kWh/t of released CO2
Levelized Cost of Direct Air Capture
< 300 €/t
