However, the weak policies and economic drivers for CCS have slowed down the commercialization of CO 2 capture technologies needed for large scale removal. At the same time CO 2 for the food and beverage industry is an existing and currently growing market for which the monoethanolamine (MEA)-based approach to provide CO 2 is very energy intensive and in many cases not economical. Finding existing applications for next generation CO 2 capture technologies at the small to medium-scale provides an important intermediate step for demonstrating and gaining the necessary knowledge required for further scaling up of novel CCS technologies. Low temperature CO2 capture represents a novel alternative to state-of-the-art MEA post-combustion technology. The separation process aims at reducing the flue gas temperature from ambient to a low temperature range at which the CO 2 freezes to be able to be removed from the main gas stream in a solid phase. This study presents the results of the assessment of integrating a novel low temperature CO 2 capture technology into a Jenbacher reciprocating gas engine by investigating two different configurations of the low temperature CO 2 capture process and comparing their performance with a stateof-the-art MEA absorption process. Results indicate that both configurations of the low temperature CO 2 removal processes enable reduction of the specific energy requirement to capture CO 2 by approximately 35% compared to the state-of-the-art MEA process.
