Abstract

Highlights: The most recent achievements for Ca-Cu looping technology are reviewed. Experimental validation of the different Ca-Cu process stages is revised and discussed. Application in hydrogen, ammonia, steel and power production plants is revised. Research needs on experimental testing, reactor arrangement and economic analyses are given. Abstract: Highly efficient pre-combustion systems are sustainable alternatives for producing hydrogen with reduced carbon footprint. The Ca-Cu looping process is a novel CO2 capture process that combines Sorption Enhanced Reforming (SER) for the production of (almost) pure H2 with a Cu/CuO redox cycle to regenerate the CO2 sorbent with a low energy penalty and potential reduction in capture cost. Over the last few years, the Ca-Cu looping process has seen noticeable progresses in its development and has recently been demonstrated up to TRL4/5 within the Ascent EU project, under conditions that are relevant for a range of industrial applications. This work reviews the most recent achievements and open gaps of knowledge in the development of this emerging process, focusing on experimental validation performed in lab-scale fixed bed reactors and on techno-economic assessment of the application in industrial plants for hydrogen, ammonia and steel production.
