Presentation Description
The leading technology for CO2-capture is based on the use of liquid absorbents, across a broad range of quite different applications. Over the last decades, the frontier of capture technology development has gradually shifted towards the lower CO2-partial pressure levels. Also, the composition of the CO2-containing source gases has dramatically changed with a more recent shift towards emissions abatement from the hard-to-abate industries and the growing interest in CO2-capture from air. This means that the liquid absorbent CO2-separation process development has been one of continuous adaptation to changing circumstances and shifting focus. The context for CO2-capture will also increasingly involve CO2-utilisation options in addition to CO2-storage.
The presentation will provide an overview of CSIRO’s work in liquid absorbent CO2-capture over the last two decades. It will discuss how emerging challenges were addressed and what solutions were developed and also provide some insights into the challenges ahead.
