Dotz’ Sorbent Technology Demonstrates Potential to Significantly Drive Down the Cost of Carbon Capture 

Validation tests and process simulations performed by SINTEF, yielded enhanced performance: DotzEarth nanoporous sorbent showed a 3-fold increase in adsorption capacity, higher selectivity, and lower regeneration energy compared to commercially available activated carbon

Dotz Nano Limited (ASX: DTZ, OTC: DTZNY), a leading developer of innovative climate and industrial nanotechnologies, is pleased to announce DotzEarth’s successful performance in testing performed in SINTEF’s labs, which showed superior results compared with existing commercial activated carbon sorbents. The company has also completed a bench-scale demonstration unit.

Dotz CEO Sharon Malka said: “As the world fast tracks the capture of CO2 to achieve global net zero by 2050, one of the main factors hindering these efforts is the high cost of capture. Carbon-based sorbents have long been identified as a cost-efficient method, and we are thrilled to see validation testing and process simulations results demonstrating our sorbents’ enhanced properties compared with commercially available carbon-based sorbents. This includes greater adsorption capacity, better selectivity, and a reduction in regeneration energy, highlighting the potential of our DotzEarth sorbent technology to offer substantial practical advantages for the future of carbon capture.”

SINTEF Research Manager, Jasmina H. Cavka said, “As a pioneer in the research and development of climate technologies, with longstanding experience in CCUS technologies, the initial results obtained on the Dotz’s adsorbent speak directly to strength of the technology, showing superior properties compared with commercial sorbent case study. These enhanced properties further support potential cost savings and provide a basis for advancing the technology towards its next stage of demonstration.”

Dotz’s nanoporous carbon sorbent testing and validation conducted at SINTEF labs, showed a 3-fold increase in adsorption capacity when compared to a commercially available activated carbon sorbent (at 10 kPa) and significantly higher selectivity vs. nitrogen (N2). 

Process simulations using SINTEF’s validated Moving Bed Temperature Swing Process (“MBTSA”), resulted in superior results compared with commercial sorbents. Most importantly, use of the Dotz nanoporous carbon adsorbent reduces the energy required for sorbent regeneration and release of CO2 (energy penalty), which was significantly lower than energy requirements of commercial activated carbon and commercial liquid amines.
