CO2 capture, utilization and storage

Lignocellulosic biomass is a renewable resource for which conversion into bioethanol is a promising avenue for producing alternative, low-carbon fuels. Converting this biomass requires a pretreatment step to break it down. However, this process generates compounds that can inhibit the action of enzymes used to hydrolyze cellulose into glucose, thereby reducing the efficiency of this reaction. In order to improve the profitability of such processes, these inhibitors need to be identified, but their presence in a highly complex environment composed of several hundred products is a real challenge.

The average global temperature has already risen by more than 1°C. What is to blame? The increase in the concentration of greenhouse gases, including CO2, in the atmosphere caused by human activities. To limit future increases, technologies known as CCUNET, which combine CO2 utilization and negative emissions, show great promise: capturing, converting, and then storing CO2 from the atmosphere would not only reduce atmospheric CO2 concentrations, but also reduce the extraction of fossil fuels.
