Abstract
CO 2 Solutions Inc. of Québec, Canada has commercialized a proprietary low-cost, enzyme accelerated solvent technology for the capture of carbon dioxide and its beneficial reuse. Enzyme catalyzed aqueous salt solutions can be deployed with a variety of gas scrubbing equipment configurations to replace costly and environmentally challenged amines solvents as an efficient solution for post-combustion CO 2 capture. The presentation will discuss the results of its 10 tonne-CO 2 /day demonstration carried out in the summer and fall of 2015 in Salaberry-de-Valleyfield (“Valleyfield), near Montreal, Canada. The Valleyfield project was the largest-ever scale test of an enzyme-based CO 2 capture process and used an industrially robust form of carbonic anhydrase enzyme developed by CO 2 Solutions to capture CO 2 from a natural gas fired boiler. The demonstration operated successfully for a total of more than 2,500 hours and saw stable performance of the enzyme catalyst, stable solvent performance with negligible degradation, no wastes generated, and highly pure CO 2 produced suitable for a broad range of reuse applications. In addition, the use of low-grade, nil-value heat for solvent regeneration at low temperature was accomplished, demonstrating this innovative method of operating cost savings. The presentation will include performance aspects of the demonstration and associated techno-economics of the technology for application to electricity and steam generation. An update on the technology's commercial implementation will also be provided.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
