Use
of
Biomass
for
SNG
 The
use
of
biomass
to
generate
SNG
could
be
the
most
interesting
scenario.
SNG
production
from
 biomass—also
referred
to
as
“bio‐SNG”—has
advantages
because
biomass
is
carbon‐neutral,
and
above
 all,
CO2
capture
would
generate
negative
carbon
emissions.
The
challenges
of
using
biomass
instead
of
 coal
arise
due
to
the
chemical
composition
of
biomass,
the
lower
calorific
value
per
unit
of
biomass
 compared
with
coal,
and
the
higher
moisture
content
of
biomass.
One
of
the
issues
associated
with
 biomass
gasification
is
tar
formation.
The
seasonal
variation
in
the
biomass
supply
and
moisture
content
 could
require
large
storage
and
drying
capacities
for
commercial‐scale
biomass
gasification
units.
 Another
possible
way
of
utilizing
biomass
would
be
in
a
coal‐biomass
co‐gasification
process.
Co‐ gasification
could
make
it
possible
to
install
large‐scale
gasification
capacity,
which
could
be
more
 commercially
viable.

 Synthetic

(SNG):
Technology,
Environmental
Implications,
and
Economics
 The
concept
of
biomass‐to‐SNG
is
relatively
new.
The
process
components
for
coal
and
biomass
should
 be
similar,
although
there
may
be
slight
differences
in
the
gasification
and
tar
removal
processes.
The
 fluidized‐bed
gasifier
may
be
better
suited
for
biomass
gasification
as
it
can
handle
variations
in
size,
 density,
moisture,
and
tar
formation.
