Carbon Capture and Utilization in the Industrial Sector
The
fabrication and manufacturing processes of industrial commodities
such as iron, glass, and cement are carbon-intensive, accounting for
23% of global CO<sub>2</sub> emissions. As a climate mitigation strategy,
CO<sub>2</sub> capture from flue gases of industrial processesî—¸much
like that of the power sectorî—¸has not experienced wide adoption
given its high associated costs. However, some industrial processes
with relatively high CO<sub>2</sub> flue concentration may be viable
candidates to cost-competitively supply CO<sub>2</sub> for utilization
purposes (e.g., polymer manufacturing, etc.). This work develops a
methodology that determines the levelized cost ($/tCO<sub>2</sub>)
of separating, compressing, and transporting carbon dioxide. A top-down
model determines the cost of separating and compressing CO<sub>2</sub> across 18 industrial processes. Further, the study calculates the
cost of transporting CO<sub>2</sub> via pipeline and tanker truck
to appropriately paired sinks using a bottom-up cost model and geo-referencing
approach. The results show that truck transportation is generally
the low-cost alternative given the relatively small volumes (ca. 100
kt CO<sub>2</sub>/a). We apply our methodology to a regional case
study in Pennsylvania, which shows steel and cement manufacturing
paired to suitable sinks as having the lowest levelized cost of capture,
compression, and transportation
