Enabling safe and efficient CO2 transport for carbon capture networks

Carbon capture and storage (CCS) projects rely on pipelines to move large volumes of carbon dioxide safely and efficiently from capture sites to permanent storage.

As new CO2 networks are commissioned and existing infrastructure is repurposed, operators face a different operating environment from traditional natural gas transmission. Dense phase behavior, higher operating pressures, corrosion risk from impurities, and evolving regulatory requirements all demand precision engineering and continuous monitoring.

Atmos supports CO2 pipeline operators with integrated simulation, leak detection and regulatory compliance solutions that provide operational visibility, predictive insight and rapid response.

The pipeline industry is facing a new operating reality

The energy transition is reshaping pipeline infrastructure. Networks are being repurposed for hydrogen and CO2, while new CCS systems are being developed under evolving regulatory frameworks.

With over 650 CCUS projects targeting operation by 2030, operators must validate designs, manage new fluid behavior, and maintain safety margins from day one.

Protect your CO2 infrastructure from day one

Carbon dioxide transport is central to carbon capture networks. Whether you are building new CO2 pipelines or repurposing existing gas assets, the commercial and regulatory stakes are high.

You need to know:

  • Will the pipeline operate safely within pressure limits?
  • How will it respond to transient events?
  • Can we detect leaks quickly and reliably?
  • Are we compliant with rupture response requirements?
  • Are we using our installed capacity efficiently?
  • Can we demonstrate regulatory and operational control to stakeholders?

Atmos delivers integrated simulation, leak detection and regulatory compliance solutions that give CO2 pipeline operators clarity and control from commissioning through long-term operation.

Validate your CO2 pipeline design before you commit capital

CO2 behaves differently from conventional natural gas, particularly under dense phase operating conditions. Pressure, temperature, and inventory management require precision.

Atmos SIM creates a high-fidelity digital twin of your pipeline so you can:

Instead of discovering limits during operation, you understand them in advance with Atmos SIM.

This reduces commissioning risk, protects capital investment and supports confident network expansion. It also provides a structured foundation for operational procedures, emergency planning, and regulatory engagement from the outset.

When your CO2 pipeline goes live, you are operating within defined limits, not testing them in real time.

Stay ahead of pressure limits and operational risk

CO2 transport networks are dynamic. Injection rates change. Storage facilities cycle. Interconnected systems introduce operational dependencies.

Atmos SIM runs in real time alongside your control system, continuously reconciling measured and modeled data. This enables operators to:

CO2 Stay Ahead Of Pressure Limits And Operational Risk

  • Forecast pressure behavior across the network

  • Predict survivability time under constrained conditions

  • Evaluate the impact of supply or compressor trips

  • Assess ramp-up scenarios before committing

  • Manage linepack within defined operating limits

Look-ahead capabilities allow you to transform operational planning from reactive to proactive and see risk forming before it becomes a problem.

Detect and respond to CO2 leaks quickly and confidently

CO2 pipelines operating at high pressure demand fast and reliable leak detection.

Atmos provides integrated leak detection technologies suitable for CO2 service, including:

Web GUI For CO2 And Carbon Capture

  • Statistical volume balance using sequential probability ratio testing

  • Real-time transient model-based detection

  • Continuous reconciliation of measured and calculated pressures and flows

These systems identify abnormal conditions quickly and provide clear alarms aligned with operational procedures.

Leak detection is not isolated from simulation. It operates within a broader monitoring framework, providing context and reducing false confidence or unnecessary shutdowns.

The objective is simple: detect early, respond decisively, and minimize operational and environmental impact.

Stay aligned with evolving CO2 pipeline standards and regulations

CO2 transport infrastructure operates under increasing regulatory and public scrutiny. In addition to national requirements, international standards such as ISO 27913:2024 define guidance for the safe transportation of carbon dioxide in CCS systems.

Compliance is not a one-time exercise. It requires continuous validation of operating limits, monitoring systems, response procedures, and documentation.

Atmos provides ongoing regulatory compliance support to help operators:

CO2 Regulations Graph GIF

  • Interpret and apply evolving CO2 pipeline standards

  • Validate detection thresholds and response logic

  • Align monitoring systems with rupture and pressure loss requirements

  • Conduct structured compliance gap analysis

  • Prepare technical documentation for audits and regulatory engagement

  • Adapt operating models as standards and guidance evolve

By embedding compliance into your simulation and leak detection framework, regulatory alignment becomes part of daily operations, not an external burden.

Increase usable capacity without compromising safety

As CO2 networks scale, commercial performance becomes critical. Operators must balance pressure limits, safety margins, and throughput targets.

Using advanced simulation and optimization capabilities, Atmos helps operators:

  • Manage linepack strategically

  • Harmonize pressures across interconnected systems

  • Reduce unnecessary flow reductions

  • Improve utilization of installed transport capacity

  • Support efficient blending and constraint management
