Calcium Looping Technology, a competitor with amine scrubbing for CO2 capture, is now being demonstrated at the 1.7 MWth scale with plans for a 10 MWth plant. It can also supply heat for fluidized bed gasification processes by enhancing the water-gas shift reaction. However, sorbent regeneration to produce a pure CO2 stream currently requires a costly oxy-fired CFBC calcination system, albeit at one third scale of a full oxy-fuel plant, and practical calcination times demand high temperatures (~900-950°C) that exacerbate the rapid decline in sorbent capture performance.

钙回路技术是胺洗涤二氧化碳捕获的竞争对手，目前正在以1.7 MWth规模进行演示，并计划建造10 MWth工厂。 它还可以通过增强水煤气变换反应为流化床气化过程提供热量。 然而，吸附剂再生以产生纯CO2流目前需要昂贵的氧燃烧CFBC煅烧系统，尽管是全氧燃料装置的三分之一规模，并且实际煅烧时间需要高温（~900-950°C），这加剧了吸附剂捕获性能的快速下降。
