Organization Name: Research Triangle Institute (RTI)
Project Title: Novel Non-Aqueous CO₂ Solvents and Capture Process with Substantially Reduced Energy Penalties

RTI is developing a solvent and process that could significantly reduce the temperature associated with regenerating solvent and CO₂ captured from the exhaust gas of coal-fired power plants. Traditional CO₂ removal processes using water-based solvents require significant amount of steam from power plants in order to regenerate the solvent so it can be reused after each reaction. RTI’s solvents can be better at absorbing CO₂ than many water-based solvents, and are regenerated at lower temperatures using less steam. Thus, industrial heat that is normally too cool to re-use can be deployed for regeneration, rather than using high-value steam. This saves the power plant money, which results in increased cost savings for consumers.
