Duke
Energy
is
proposing
to
invest
approximately
$121mn
for
a
detailed
characterization
of
storage
sites,
including
the
drilling
of
multiple
wells.
The
project
involves
exploring
storage
in
deep
saline
aquifers
as
well
as
use
in
enhanced
oil
recovery
and
storage
in
depleted
oil
or
gas
fields.
In
enhanced
oil
recovery,
CO2
is
used
to
help
promote
oil
and
gas
production
underground.
The
three-year
site
characterization
would
result
in
about
a
one
percent
average
customer
rate
increase
phased
in
between
2010
and
2013.
If
the
study
is
successful,
Duke
Energy
will
ask
state
utility…
