The Role of CO2-EOR for the Development of a CCTS Infrastructure in the North Sea Region: A Techno-Economic Model and Application

Scenarios of future energy systems attribute an important role to Carbon Capture, Transport, and Storage (CCTS) in achieving emission reductions. Using captured CO2 for enhanced oil recovery (CO2-EOR) can improve the economics of the technology. This paper examines the potential for CO2-EOR in the North Sea region. UK oil fields are found to account for 47% of the estimated additional recovery potential of 3739 Mbbl (1234 MtCO2 of storage potential). Danish and Norwegian fields add 28% and 25%, respectively. Based on a comprehensive dataset, the paper develops a unique techno-economic market equilibrium model of CO2 supply from emission sources and CO2 demand from CO2-EOR to assess implications for a future CCTS infrastructure. A detailed representation of decreasing demand for fresh CO2 for CO2-EOR operation is accomplished via an exponential storage cost function. In all scenarios of varying CO2 and crude oil price paths the assumed CO2-EOR potential is fully exploited. CO2-EOR does add value to CCTS operations but the potential is very limited and does not automatically induce long term CCTS activity. If CO2 prices stay low, little further use of CCTS can be expected after 2035

Towards a New Political Economy of Climate Change and Development

In this article, the authors propose a new political economy of climate change and development in which explicit attention is given to the way that ideas, power and resources are conceptualised, negotiated and implemented by different groups at different scales. The climate change and development interface warrants such attention because of its importance to achieving sustainable poverty reduction outcomes, cross‐sectoral nature, urgency and rapid emergence of international resource transfers, initiatives and governance architectures, and the frequent assumption of linear policymaking and apolitical, techno‐managerial solutions to the climate change challenge

Method to identify opportunities for CCU at regional level — Matching sources and receivers

Carbon Capture and Utilization is an attractive strategy not only due to its potential for CO2 emissions reduction but also because it enables the creation of valuable products. The development of CO2-based industrial symbiosis partnerships can contribute significantly towards achieving the goals of GHG emissions reduction on a European level by 2030, while at the same time it leads to an increased added value through the development of new production lines and carbon neutral products. The presented article focuses on identifying potential partnerships between companies that produce CO2 and companies that may reuse CO2 as input for their industrial process. A novel methodological framework is presented based on developing generic matrices for CO2 sources and receivers and matching the industrial units based on geographical and technical criteria. Moreover, the paper provides the technical requirements of 17 CO2 utilization technologies with relatively high technology readiness level, including the CO2-to-product ratio, the required purity, pressure, temperature and the presence of a catalyst, as well as potential synergies and additional requirements. The methodology has been applied to the Västra Götaland region in West Sweden and the most promising CCU symbiosis have been identified. These include mineral carbonation (annual uptake: 59,600 tCO2), greenhouses (26,000 tCO2), algae production, methanol production (85,500 tCO2), power to gas (66,500 tCO2), pH control, lignin production, polymers synthesis and concrete curing (96,000 tCO2). If all of them could be applied, the total annual CO2 reduction would exceed 250,000 tCO2 per year
