Monitoring and Control of Networks for CCS

Alternative title: Overvåking og kontroll av CCS-nettverk

Awarded: NOK 13.9 mill.

Carbon Capture and Storage (CCS) is seen as a promising technology to meet climate goals. In a not-so-distant future, the CCS clusters consisting of different CO2 sources with large variations in flow rates, operating conditions, and impurity content are expected. This scenario challenges the transport operations and precludes reliable flow of CO2 to the permanent storage site. MACON CCS aims to aid in CCS becoming a widespread, efficient climate policy instrument by tackling identified barriers in monitoring and controlling upcoming CCS transport networks. The project has just started, and we are preparing the groundwork to target pressing data gaps for the development of efficient and robust predictive flow models, along with sensor technology assessments for monitoring of CCS streams in real-time. The scientific results of MACON CCS will have the potential to enable large-scale deployment of CCS from industrial sources and the long-term business case of the Norwegian large-scale project for CO2 transport and storage infrastructure (Northern Lights). To unlock the potential discussed above, MACON CCS brings together key industrial and research players in a consortium aiming for excellence in innovation and research. The project is coordinated by SINTEF Energy Research, who, along with NTNU, undertakes the core of the research activities and educate PhD and MSc students. The industrial partners TechnipFMC, Roxar, KROHNE, and Norsk Elektro Optikk contribute with know-how and equipment, including sensors, meters, and systems for monitoring and control.

MACON CCS will be an enabler for large-scale deployment of CCS from industrial sources and the Northern Lights long-term business case by addressing selected and internationally recognized barriers in monitoring and control of diverse industrial CCS transport networks. Such networks, with CO2 sources like e.g., gas reforming for hydrogen and bio-energy processes, will have large local and temporal variations in flow rates, conditions, and impurity content, with distinctively different flow assurance challenges than in natural gas transport. Some species that originates from industrial sources, like H2, NOx, sulfuric components, water, ammonia, and amines may even in small concentrations have a large impact on the phase behaviour of CO2-rich fluids. The formation of a second phase could have consequences such as plugging, reduced lifetime of rotating machinery, and inaccurate metering. In addition, a minority phase will typically be enriched in the impurity, which could be toxic, corrosive and/or flammable. MACON CCS will close gaps in thermodynamic data for such species and develop efficient and robust thermodynamic models. Further, sensor technology needed for monitoring such networks in terms of flow rates, phase state, and composition will be evaluated. The thermodynamic models and acquired knowledge on sensors will be used to develop a metering and allocation philosophy for intelligent monitoring and control systems. Flow assurance and operability issues in CO2 networks will be investigated. A predictive module for dedicated control, leak detection and mass balance will be developed. MACON CCS will be coordinated by SINTEF Energy Research which will contribute in most project tasks. TechnipFMC will contribute with their know-how and systems for monitoring and control. Roxar and KROHNE will provide sensors, meters, and expertise on flow monitoring. Norsk Elektro Optikk will contribute industrial spectroscopy knowledge. NTNU will educate PhD and MSc candidates.
