Norwegian CCS Value Chain Mapping

Motivation: 

The client, a Norwegian exploration license holder, was interested in exploring a series of different CCS value chains, for both long and short distances, at high and low volumes, to deliver CO₂ to its stores in the Norwegian North Sea. This was to inform both technical and commercial workstreams, as the project was at early stage with emitter and development concepts were being investigated.

Our Approach: 

The study approach started by framing up the different value chains to be assessed on a detailed basis, before reviewing any data gaps to generate further conclusions and insights.

Framing and scoping: 

• Initial workshop held to agree key parameters such as study boundaries and scope
• Pre-screening carried out to identify which transportation options and receiving infrastructure pairings would be deemed sub-optimal for the project location
• A value chain strategy table was subsequently created in collaboration with the client to agree on which value chains should be assessed in detail. This resulted in ten different value chain variations considering pipeline and shipping transportation options paired with several different offshore facility concepts

Detailed assessment of specific value chains: 

• A techno-economic assessment was carried out including, but not limited to steady state simulations, emissions assessment, power supply review, shipping logistics, and cost estimations
• This resulted in quantitative metrics for power demand, emissions intensity, availability and levelised cost of transportation and storage (LCoTS)
• Further qualitative metrics were also assessed including schedule, regulatory, and CO₂ specification
• Specific value chain insights and conclusions were drawn, highlighting areas of further study or considerations when building the value chain

Benefit and Impact: 

Collaborative working with the client generated tailored insights based on the data generated for each of the value chains. In combination with the technology and solution agnostic approach, this matured the client's understanding of the potential value chains without external bias. Key factors which influenced a value chain's viability were the impact of shipping technology selection for different distances and volumes, vessel logistics when accessing multiple customers, and buffer storage across the value chain.
