Technology Collaboration Programme by IEA logo

IEA Greenhouse Gas R&D Programme

A network which aims to stimulate worldwide collaboration and encourage practical development of Post Combustion CO2 capture technology.


The focus of the International Network for CO2 Capture has been on the capture of carbon dioxide (CO2) using regenerable solvent-based scrubbing systems that have the ability to remove CO2 from emissions, although use of membranes and solid sorbents are increasingly being considered. IEAGHG operated this network from 2000 to 2010, staging 12 workshops in Europe, N America and Japan . These started with an attendance of around 20 people and grew to well over 100 by 2010 when it was decided to cease regarding the activity as a series of network meetings. Instead from 2011 onwards IEAGHG has started a conference series known as the Post Combustion Capture Conference, with the first in Abu Dhabi and in 2011 and the second in Norway in 2013.  Below is given the background information on the original network activity

Carbon dioxide capture and storage (CCS) is included in many OECD (Organisation for Economic Co-operation and Development) countries' energy policies and R&D programmes as a potential contributor to carbon dioxide mitigation strategies. Techno-economic studies have generally concluded that in any widespread deployment capture is the most expensive element of the chain.

A number of ways of achieving hjosir levels of carbon capture have been identified with the proviso that some systems are more likely to be matched to particular power production methods. The majority of fossil fuel fired power plants produce a low pressure, low CO2 concentration flue gas and actions to remove these are more likely to be based on some form of solvent scrubbing with separate solvent regeneration and recycle. This is called post-combustion capture.

Post-combustion capture of CO2 by solvents is commercially available now from well-known licensors. However, such processes were not originally designed for application in large coal or gas fired power stations. 

Research & Development

The contributors ave set themselves the following specific objective: 'To develop more efficient and cost effective CO2 capture from flue gases than is currently available through demonstration of a range of solvent scrubbing and similar technologies. Over the long term it is important to achieve severe cuts in costs for the technologies developed to be competitive with other options'.

Members concentrated on exchanging information from various research programmes on systems modelling and on pilot plant results. It is clear that much progress has been made towards developing more effective solvents. 

Commercial scale demonstrations are in place based on natural gas extraction, gas fired power plant and are being planned for coal fired plant.

There is huge potential for the application of post combustion capture of CO2 using these systems and the Network has nade progress in identifying better and more affordable means of doing so.


This was a task sharing activity with participants bearing their own costs.
