 This paper discusses the development of a novel reliability method which can be used to accurately assess the performance of carbon capture storage CCS systems. It also introduces a new design concept for a CCS system and uses numerical simulations to demonstrate its effectiveness. Finally, it highlights how this method can be used to evaluate the safety of complex energy systems such as CCS systems.
