Our flagship adsorbent
CALF-20. The solid adsorbent with a documented performance record.
Most next-generation solid adsorbents have promising laboratory data. Few have been tested independently, repeatedly, and under the conditions that actually exist in industrial operation: humid flue gas, acid gases, oxygen, variable temperatures, and multi-cycle stress.
CALF-20 has. More than 40 independent research groups across Canada, the United States, Europe, and Asia have published studies confirming its performance. The foundational paper, published in Science, has been downloaded more than 100,000 times. That body of evidence is public, peer-reviewed, and available for any technical team to examine.
CALF-20 captures CO2 through physisorption. Physical interactions hold CO2 molecules efficiently during capture and release them with much lower energy demands than chemical sorbents require. The mechanism holds up under real industrial conditions, including water vapor, SOx, NOx, and oxygen without extensive flue gas dehydration. This means lower regeneration energy, lower total cost of capture, and performance that does not require idealized gas preconditioning.
CALF-20 is not a research stage material. It can be shaped into industry-ready form factors. Existent makes CALF-20 available to any qualified buyer, at any scale, for any qualifying application.
Our sorbents, including our flagship CALF-20 sorbent, make gas separations like carbon capture simpler to design, simpler to integrate, and more predictable to operate. They provide an option for teams that need real performance under real conditions.
What Existent offers
CALF-20 in the form you require
Industrial Deployment
Shaped CALF-20, including extrudates and other forms are available for packed-bed system design, pilot programs, and commercial scale deployment. For teams developing systems around CALF-20, we engage directly on form factor selection, scale-up planning, and long-term supply.
R&D Evaluation
Powdered CALF-20 is available from 1 gram through kilogram quantities for laboratory screening, isotherm measurement, breakthrough testing, and feasibility studies. Every order ships with CO2 isotherm data at 298 K. No black-box material risk for your R&D team.
Who we are
Existent is founded by an operator-inventor team deploying CALF-20, and new advanced adsorbents.
Adrien Côté
CEO and co-founder
Adrien Côté builds commercial pathways for advanced materials. His background spans inorganic chemistry research, 50+ patents from materials scale-up at Xerox, and leading one of Canada’s most active startup commercialization programs. His postdoctoral research was conducted in a laboratory that later produced a Nobel laureate in Chemistry for metal-organic frameworks.
George Shimizu
CTO and co-founder
George Shimizu is the inventor CALF-20 and is Professor of Chemistry at the University of Calgary. He drives materials from discovery-driven research at TRL 0 through industrial deployment at TRL 9. His understanding of CALF-20 runs from its molecular design to its industrial deployment. He is the recipient of many research and industrial innovation awards.
