The study is based on a literature and web review of the status of emerging (2nd and 3rd generation) CO2 capture technologies and existing test facilities. It was performed jointly by the CSLF Policy and Technical Groups. Neither the inventory of emerging technologies nor of test facilities can be regarded as complete. nd rd Around 30 groups of 2 and 3 generation CO2 capture technologies
