Unformatted text preview: long
pilot
run
in
November
2007.
The
pilot
plant
for
the
process
is
a
60‐foot‐high
gasifier
with
an
 internal
diameter
of
14
inches.
A
proposed
large
pre‐commercial
plant
is
expected
to
be
operational
by
 2009.
The
price
of
pipeline‐quality
gas
by
GreatPoint
Energy’s
process
could
be
less
than
$3
per
MMBtu
 (Fairley
2007).
GreatPoint
Energy
Inc.
and
Peabody
are
working
together
to
commercialize
the
 technology
with
the
goal
of
developing
a
coal‐to‐SNG
plant
at
or
near
Wyoming’s
Powder
River
Basin
 area
(GreatPoint
Energy
2008b).
 2.4.2.
Commercial
SNG
plants
planned
in
the
U.S.
 Table
2
shows
that
there
are
at
least
15
coal‐to‐SNG
plants
proposed
in
U.S.,
all
in
different
stages
of
 development.
Some
of
these
plants
are
also
considering
carbon
capture
and
storage.
For
example,
the
 joint
ConocoPhillips/Peabody
Energy
project
in
the
Midwest
is
considering
CO2
capture
and
storage
for
 its
mine‐mouth
facility
(ConocoPhillips
2007).
An
Indiana
Gasification
LLC
plant
in
southwest
Indiana
 would
demonstrate
geologic
CO2
sequestration
(Indiana
Coal
to
SNG
2008).
Secure
Energy
Inc.’s
plant
in
 Illinois
would
use
10%
biomass
for
SNG
generation.
