OSLO, NORWAY - 6 July 2023 - Circa Group AS (stock symbol: CIRCA) has applied
for patents for two new solvents for CO2 capture processes. 

As both the interest and the urgency to capture and transform carbon dioxide
(CO2) emissions increases, Circa has developed two new CO2 solvents from its
platform molecule, levoglucosenone (LGO).

The two new solvents named Furatech:1 and Furatech:2 are the product of 12
months of development and testing across a range of new LGO-based molecules
within Circa's R&D team. 

The Furatech products have been designed to be used in several current CO2
capture processes and discussions are underway about further optimisation with
our engineering partners.

"Applying for patents is a major step and we are sufficiently excited about the
performance of these two new CO2 solvents that getting protection in place as
quickly as possible is a priority," says Tony Duncan, Circa CEO. "Furatech
testing has shown good CO2 capture performance across multiple cycles, as well
as lower energy requirements in the desorption phase compared to current
industry standards."

With the ReSolute plant commissioning planned for mid-2024, further testing and
trialling of Furatech:1 and Furatech:2 will continue in parallel.
