Carbon Capture, Utilization and Storage

MGRRE Resources
What is carbon capture, utilization and storage (CCUS)?
CCUS involves the capture of CO2, generally from large point sources like power generation or industrial facilities that use either fossil fuels or biomass as fuel. If not being used on-site, the captured CO2 is compressed and transported by pipeline, ship, rail or truck to be used in a range of applications, or injected into deep geological formations such as depleted oil and gas reservoirs or saline aquifers.

What is the role of CCUS in clean energy transitions?

CCUS can be retrofitted to existing power and industrial plants, allowing for their continued operation. It can tackle emissions in hard-to-abate sectors, particularly heavy industries like cement, steel or chemicals. CCUS is an enabler of least-cost low-carbon hydrogen production, which can support the decarbonisation of other parts of the energy system, such as industry, trucks and ships. Finally, CCUS can remove CO2 from the air to balance emissions that are unavoidable or technically difficult to abate.

Combining CO2 Sequestration with enhanced oil recovery to reduce global warming and produce more domestic energy

Large volumes of technically recoverable domestic oil resources remain undeveloped or are yet to be discovered in the United States. The EOR potential associated with CO2 represents a large portion of this potential. Undeveloped U.S. domestic oil resources that are still in the ground (in-place) total 1,124 billion barrels. Of this large in-place resource, 430 billion barrels are estimated to be technically recoverable. This resource includes undiscovered oil, “stranded” light oil amenable to CO2 EOR technologies, unconventional oil (deep heavy oil and tar sands) and new petroleum concepts (residual oil in reservoir transition zones). Michigan is typical of mature basins where initial wells produced only about 30 percent of the hydrocarbons in place. Using CO2 injection to increase formation pressure and reduce oil viscosity can produce another 20 percent, potentially bringing millions of additional barrels of oil to production annually.
