CCS - Feasibility study for liquefaction and transport of CO2 for decarbonization of incineration plant

Assignment

Norconsult assisted Returkraft AS in exploring the feasibility of carbon capture from the plant exhaust gas. Norconsult scope was to evaluate technical solutions for condition, liquefaction and intermediate storage of CO2. In addition, alternative transport solutions were evaluated.

Solution

Norconsult explored several concept solutions for handling the CO2 value chain from conditioning, liquefaction, intermediate storage to transport to the port location for shipment.

As part of the study, greenhouse gas calculations were carried out to assess the total greenhouse gas emissions of establishment and operation of the proposed concepts.

Transport solutions evaluated were
train, road tanker and pipeline transport. Process simulations were used to develop a pipeline concept. Concepts for handling and transport solutions were cost-estimated and evaluated against each other based on a multi-criteria matrix. Technical safety and assessments of risk factors associated with the handling and transport of CO2 were also evaluated.

Result

Based on an assessment of technical feasibility, costs and greenhouse gas emissions, transport by road tanker to a local port or train transport both locally and regionally showed to be preferable logistic solutions.

The technical feasibility and logistic study were used as basis for applications for CCS funding programs and regional cluster collaborations.
