Background
A cleantech company was adapting a carbon capture sorbent technology for a specific industrial facility, but the facility’s flue gas contained impurities not present in the conditions the sorbent was originally developed and validated for.
The Challenge
It was unclear whether the sorbent’s capture efficiency could be maintained in the presence of these impurities, or whether the impurities would degrade sorbent performance faster than published data for cleaner gas streams suggested.
Technological Uncertainty
It was not known in advance whether the sorbent’s capture efficiency and regeneration behaviour would hold up under this specific flue gas composition, or what modification, if any, could mitigate impurity-related performance loss.
Experimental Development
The team systematically tested sorbent performance under simulated flue gas conditions matching the facility’s actual composition, measuring capture efficiency, regeneration behaviour, and degradation rate across multiple sorbent formulation variants.
What Failed?
The original sorbent formulation showed significantly accelerated degradation in the presence of the facility’s specific impurities, and an initial protective coating approach improved durability but reduced capture efficiency below the project’s target.
Technological Advancement
The team developed a modified sorbent formulation that balanced impurity resistance with capture efficiency, generating new technical knowledge about sorbent performance under this specific industrial gas composition.
Potentially Relevant SR&ED Activities
- Systematic sorbent performance testing under simulated site-specific flue gas conditions
- Degradation and regeneration behaviour testing across formulation variants
- Capture efficiency benchmarking across iterations
What Would Generally Not Qualify
Operating the finalized, validated sorbent system in ongoing facility operations would be routine operation and would not itself qualify as further eligible development.
Documentation
Simulated flue gas testing data, degradation and efficiency benchmarks across formulation variants, and technical notes on the impurity interactions investigated would support this claim.
