Carbon
dioxide
capture
and
storage
(CCS)
technology
is
considered
a
crucial
tactic
for
achieving
the
“dual
carbon”
goals.
However,
current
CCS
technologies
face
several
challenges,
such
as
absence
of
comprehensive
systematic
set
criteria
site
selection,
coupled
with
lack
universally
applicable
evaluation
framework.To
address
these
issues,
this
study
proposes
regional-scale
CO

geological
suitability
assessment
potential
estimation
framework
that
can
be
adapted
to
similar
regions.
Using
Yellow

This

The

key

as:

Are
