16. Current and Emerging Technologies for
Carbon Capture
Special thanks to Dr. Hussam Ibrahim of
University of Regina’s CETRI
17. Introduction
There are currently three main types
of capture technologies:
• Pre-combustion
• Post-combustion
• Oxyfuel combustion
Pre combustion: Kemper County Energy Facility
Post combustion: Boundary Dam SaskPower
Left: Allam-Fetvedt Cycle demonstration plant
(Oxy-combustion) in La Porte, Texas, NET POWER
18. Pre-Combustion Capture
• Pre-combustion capture is often
used in integrated gasification
combined cycle (IGCC) power
plants.
• In this process, coal or other fossil
fuels are converted into a gas
mixture of hydrogen and carbon
monoxide, known as syngas.
• The syngas is then burned to
generate electricity, while the
carbon dioxide is separated and
captured.
19. Post Combustion Capture
• Post-combustion capture is
the most widely used
capture technology, as it can
be retrofitted onto existing
power plants.
• This process involves
capturing carbon dioxide
from the flue gas after the
fuel has been burned,
typically using solvents or
membranes.
Shell Consolv Process Figure from Shell
20. Oxyfuel Combustion
• Oxyfuel combustion involves burning fuel in pure oxygen
instead of air, which produces a flue gas consisting mainly of
carbon dioxide and water vapor.
• This makes it easier to capture the carbon dioxide, as there
are fewer other gases present.
21. Emerging Capture Technologies
• There are also several emerging
capture technologies that are still in
the research and development stage
• catalyst-aided novel solvents-based
capture, which uses catalytically
enhanced novel solvent blends to
selectively separate carbon dioxide
from other gases.
• membrane-based capture and direct
air capture, which involves capturing
CO2 directly from the atmosphere
using special filters or chemicals.
• DAC: Direct Air Capture
Direct Air Capture Schematic
23. Transport Types
• Pipelines = predominant
established option for long
distance transportation
• Increasing U.S. interest in rail
• Tankers (both short and long
distance)
• Trucks (short distance transport of
smaller quantities)
• Ship for offshore e.g. Northern
Lights project, Norway (used for
intercontinental transport of CO2)

24. Ship Transport of CO2
https://norlights.com/
• In Europe on shore
storage has been banned
in many countries due to
public perception issues
• Ship transport using
tankers similar to natural
gas transport
• Equinor already has two
offshore projects (Sleipner
and Snohvit) but these are
platform based for CO2
and not ship based)
25. Land Transport of CO2
Photo from: TOMCO Systems
https://tomcosystems.com/product/co2-transportation/
• Land transportation of CO2 via
tanker trucks is most often
associated with pilot injection
projects for EOR or small utilization
efforts like fertilizer or cement
manufacturing
• Most utilization efforts outside of
EOR require smaller amounts of
CO2. Pipeline access would be
expensive (unless the pipelines are
near to these industrial uses)
• CO2 sources would need to have
specially fitted compression and
loading stations for ground
transport
26. Pipelines
Three primary types of pipelines for CO2
• Gathering line
• Trunk line
• Distribution line
Integrity Challenges with CO2 pipeline
• Corrosion both external and internal
• Water accumulation
• CO2 and H2O put into high pressure,
more CO2 can dissolve in the water (
soda)
• CO2+H2O H2CO3 carbonic acid
• Carbonic acid is corrosive , PH goes
down
27. Pipelines
Requirements (EPA standards) :
• Dehydrate the CO2 (dry CO2 consisting less than 50ppm
of water)
• Construct or soak CO2 pipeline with non-corrodible
materials such as polymers and fiber glass
• Water dropout traps – collect and drain excess fluids
• Pipeline exposed to the surface may be wrapped in
insulation to protect against or minimize phase change
and pressure issues resulting from changes in
atmospheric conditions
28. Can we use existing hydrocarbon pipelines?
• Integrity challenges
• Internal corrosion
• Cracking
• Multiple feeders depending on sources
• CO2 needs to be transported at 700 PSI higher
than natural gas therefore CO2 pipeline walls have
to be thicker than other types of pipeline
Pipelines: Repurposing Existing Infrastructure
Best approach to a safe conversion of
existing pipeline to CO2
• Good understanding of integrity of pipeline is a
must
• Operate CO2 in a dense phase
• Understand historical services to deploy proper
inspection strategies
• Pipeline material and fracture toughness
• Monitor metal loss and corrosion and fracture
30. Purpose of Risk Management
The purpose of risk management is to ensure that
the risk scenarios involved in CO2 storage project
are effectively managed and reduced to an
acceptable level.
31. Risk Management for CO2 Storage
Risk Management
(Containment and
Storage Performance)
• Risk Assessment
• Risk Identification, Analysis, and
Evaluation
• Risk Mitigation
• Treating, Monitoring, and
Reviewing/Reevaluating
32. Project Values & Objectives
• Articulate the objectives of the project and define the scope,
conditions, and criteria for the process for risk management.
• Identify the appropriate elements of concern for the project.
• Often defined by the values of the organization
33. Risk Evaluation Criteria
Identify the appropriate elements of concern for the project and establish risk
evaluation criteria for each element of concern based on the scope and objectives
of the project.
Evaluation Criteria
Criteria against which
each risk is evaluated
and distinguished as
acceptable, tolerable, or
unacceptable.
• Acceptable Risk
• Tolerable Risk
• Unacceptable Risk
34. The Risk Assessment Workshop
• Gathering experts to debate risks
• Structured around predetermined
risk scenarios (FEPs)
• Experts are ranked and represent
best the different aspects of the
project
• Timing of workshop is key in the
overall project workflow
• How much data is required vs. how
much data do you have
36. Risk Analysis & Evaluation
Features, Events and Processes (FEPS)
• Risk scenarios for each identified
threat
• Likelihood of each scenario
• Severity of potential
consequences
• Uncertainties associated with
likelihood and severity
• Measures to reduce or manage
uncertainties
• Risk controls to prevent or
mitigate identified risk scenarios
• Measures for timely
implementation of risk mitigation
• Data requirements and modelling
to support risk analysis

38. Oilfield Production - Lifecycle
• Primary Production -
Natural depletion of the
reservoir
• Secondary recovery –
putting energy back into
the reservoir
• Enhanced Oil Recovery
– changing the chemical
and physical properties
of reservoir fluids
Reservoir energy continues to
decline until insufficient energy exists
to force enough oil into the well to
warrant continued production.
39. Secondary Recovery
• Waterflooding most
common
• Simplicity
• Availability
• Cost
• Efficiency determined by
fluid/rock properties,
reservoir heterogeneity
and placement of wells
• Optimized traditionally by
updating reservoir models
using historical data
40. Enhanced Oil Recovery –
Solvent Injection Methods
• A solvent can mix with the
oil, form a homogeneous
mixture, and carry the oil
away from the reservoir.
• CO2, propane, methane……
CO2 Injection
• Is miscible with crude oil
• When the injected CO2 and
residual oil are miscible, the
CO2 dissolves in the oil, it
swells the oil and reduces
its viscosity

54. Why Outreach?
Local communities are very specific for each project with unique needs
• People must feel their regionally specific concerns are being met
• Communities must be involved as a project is being planned, not
informed after decisions have been made
All CCS projects globally are tied to each other
• Global concerns tied to climate change
• What happens in one project will affect another
• Early projects have responsibilities to educate and inform
Carbon Capture and Storage is a suite of complex technologies
• Understanding these are important
• Misunderstanding builds distrust and fear
55. Wrong or is it?
Right
One of the purposes of effective CCS communications is to
provide clear, scientific detail where needed. This means,
for example, the storage images should be to scale.
Image – Drawing to Scale
57. Pipeline Opposition
• Pipelines have been sited through
indigenous lands without consultation
• Rural communities without consent or
minimal consent, minimal information
leading to confusion
• Pipeline right of way can take infringe on
property surface rights
• Confusion about CO2 versus hydrocarbons
and natural gas transport (seen as same
dangers)

Introduction
58. Pipelines: The Denbury Leak 2020 Lessons Learned
Incident occurred on the Denbury Gulf
Coast CO2 Pipeline in Sataria
Mississippi, February 22, 2020
• Incident was not a human induced rupture of
the line, but one caused after heavy rain and
mudslides, leading to axial strain on the
pipeline
• Because CO2 is supercritical (liquid state) for
transport, small leakages usually immediately
turn to gas and dissipate.
• But the location was low lying, near a small
town; there was little wind
• CO2 is heavier than air and did not dissipate as
would normally be expected
• Pipeline operators are expected to prepare
atmospheric models in anticipation of leaks

59. Main failure seen as public
engagement and an effective public
outreach and emergency response plan
“Improved public engagement efforts to ensure public
and emergency responder awareness of nearby CO2
pipeline and pipeline facilities and what to do if a CO2
release occurs. This is especially important for
communities in low-lying areas, with certain
topographical features such as rivers and valleys.”

Impacts of leak:
• 45 people taken to local hospital with
symptoms of excessive CO2 exposure
• Two people retained for observation for two
days
• 200 people evacuated from area
• 21,873 barrels of CO2 gas released
• Evacuation radius was .25 miles
• Pressure drop was notices at 7:07 pm
• Leak verified at 8:46 and valve closed.

When the Project Story Stops Being About Your Project
64. Criteria for Site Closure
Site closure criteria should focus on:
• Observed CO2 plume dispersion and future
expansion of the plume.
• Reservoir pressure and future evolution of it.
• Formation fluid compositional changes resulted
from the project and implications for future fluid
movement.
• Condition of the wells, and their closure and
abandonment.
• Removal of surface facilities and equipment
associated with the storage project.
• Applicable regulations.

ports, INSAR reflector and passive seismic monitoring geophones
65. Post Closure
When site closure is complete:
• No need for future interventions
should be anticipated.
• The storage facility should be
suitable for other uses.
• Post-closure requirements are set
by regulatory authorities to ensure
long-term safety and permanence
of CO2 storage.

plan submitted to EPA
66. Summary
•Cessation of injection does not mean the storage
site is closed.
•Closure plan and criteria for site closure should be
developed by the operator.
•Once closure is complete, no future interventions
should be anticipated.
•Some countries have prescriptive post closure
regulations.
