CO2 capture : technologies to reduce greenhouse gas emissions
CO<sub>2</sub> capture and geological storage (CCS) is now recognised as
being one of the pathways that can be implemented to reduce
CO<sub>2</sub> emissions and fight against global warming. But where, how and
at what price can CO<sub>2</sub> be captured? This book attempts to provide the
answers to these questions, reviewing the state of the art of the technologies
required. It presents the three main pathways considered in
which the CO<sub>2</sub> capture technologies are expected to be implemented,
respectively: the post-combustion pathway, in which the CO<sub>2</sub> contained
in industrial flue gases is extracted; the oxy-combustion pathway, in
which combustion is performed in oxygen to obtain flue gases with
high CO<sub>2</sub> concentration; and lastly the pre-combustion pathway, in
which carbon is extracted from the initial fuel to generate hydrogen,
whose combustion will produce only water vapour. The book introduces,
for each pathway, the technologies currently available and those
under development. It is intended for everyone wanting to gain a better
understanding of the mechanisms implemented in CO<sub>2</sub> capture operations,
as well as the technological and economic challenges to be met
to ensure that the costs generated by these operations are no longer an
obstacle to their worldwide generalisation.
