This book surveys the current research on CO2 conversion processes and shows that these can
close the carbon cycle as part of a circular economy. The technical and economic feasibility of
these processes are examined together and current scientific challenges are signposted which
will guide future R&D. Technology sustainability is key for meeting and keeping decarbonization
goals in the long term. However considering economic and environmental sustainability
individually is not enough. An integral view of sustainability that incorporates an energy term
in the equation is needed. This book brings this concept to the fore.
