Heat supply alternatives for CO2 capture in the process industry

► This paper is a techno-economic analysis for CO2 capture in a process industry. ► Five heat supply options have been evaluated by using energy market scenarios. ► Using excess heat to the post-combustion process is the most robust alternative. ► If CO2 charges are high in the future, excess heat options may become profitable. ► High process integration potential makes CCS an interesting option for the industry.
