expansion plans for 2023 of the Carseland
plant, blue H2
will be available in
sufficient quantity to support up to 160
MMft3
d of 5% blend natural gas. Future
plant expansions will bring co-production
capacity to 100 metric tpd of blue H2
volumes of co-generated H2
,
which is sufficient to support up to 850
MMft3
d of 5% blend natural gas. These
, as shown by
TABLE 3, demonstrate the significant role
the Carseland GTL plant can play in supporting
the decarbonization of Alberta's
natural gas supply system.

recently completed study, the Carseland
GTL plant's current blue H2
production
capacity of 16 metric tpd could support
the integration of a 2,500-bpd-4,000bpd
canola seed oil HDRD plant (FIG. 8),
producing a combined site capacity of up
to 4,500 bpd of low-carbon diesel with a
combined CI of less than 25. The study
additionally confirmed that the propane
byproduct generated by the HDRD process
could be recycled and used as feed
for the GTL plant, reducing the plant's
demand for natural gas and further reducing
the combined CI.
From Kitimat to California: A blue H2
market opportunity. H2
production
represents a significant opportunity for
Alberta and British Columbia to move
beyond satisfying Canadian needs and
export H2
to markets possessing ambitious
decarbonization plants but lacking
the CCUS capabilities and projected lowcost,
sustainable supply of natural gas that
make these two regions so well-suited to
producing blue H2
. Potentially key export
markets for Canadian-produced blue H2
include Japan, China, South Korea and
California; a proposed GTL plant in KitiH2Tech
