Supporting the Carbon Capture Industry

Carbon Capture Usage and Storage (CCUS) projects have the potential to abate large scale industrial emissions and are likely to play an increasing role in the energy transition.

CCUS is in development internationally with companies managing risk through creation of joint venture operations. Regulatory regimes are currently under development too — for example, the UK published a draft Network Code along with guidance on the requirements for CCS Operation.

Whilst these projects will bring new technical challenges, Accord believe that in many ways they are analogous to gas transportation systems and have similar requirements, all of which can be support by Accord's experienced team. These include:

  • Technical Schedules for Commercial Agreements
  • Capacity Management
  • Planning and Forecasting
  • Nominations Managements
  • Cargo Management (shipped CO2)
  • Deliveries and Measurement
  • Commercial Models
  • Allocation and Reconciliation
  • Measurement Uncertainty
  • Revenue Models (including Tariffing)
  • Pricing and Invoicing
  • Verification and Publication of Data
  • Regulatory and Environmental Reporting

Carbon Capture Measurement and Allocation,
Delivered in Detail

Allocation Philosophies

Accord can support CCUS clients in defining approach, cost-benefit analysis, feasibility studies, stakeholder engagement and devising allocation philosophies.

Measurement Technology Review and Selection

Accord has specialist experience in the definition of CO2 measurement systems to comply with regulatory and commercial regimes. Services include selection of suitable technology and uncertainty analysis. Accord has also developed a new, improved method for measuring CO2 through an orifice meter.

System Implementations

Accord offer dedicated support for delivering systems for CCUS measurement, allocation and administration — from statements of requirements, to system design, to implementation and responsive support.

Carbon Capture Challenges

We understand the specific technical challenges faced by operators in the carbon capture, usage and storage industry, including:

  • Allocation and Attribution of CO2 deliveries at aggregation points
  • Non-ideal behaviour of CO2 at high pressures
  • Impact of impurities from different sources and industries
  • Equitable allocation of high compression power consumption
  • The "Long Pipeline Effect"
  • Calculation of uncertainties

The NSTA Guidance for Measurement of Carbon Dioxide and Carbon Storage Permit Applications references two papers by our team:

  • Cost Benefit Analyses in Design of Allocation Systems (2009)
  • Meeting the Challenges of CO2 Measurement with New Kind of Orifice Meter (2021)

"As a number of CCUS projects in Northern Europe approach FID, we have the opportunity to employ our experience from the oil and gas sector to develop new solutions to meet the requirements of this emerging sector."
