Pacific Northwest National Laboratory (PNNL) developed transformational carbon dioxide (CO2) capture solvents based on their nonaqueous switchable organic solvents, known as CO2-binding organic liquids (CO2BOLs). The project focus used computation-aided molecular design to optimize, synthesize, and characterize CO2BOLs with a CO2-rich viscosity of less than 50 cP at a cost of less than $10/kg.
