The Synergetic Utilisation Of CO2 Storage Coupled With Geothermal Energy Deployment (SUCCEED) project brings together eight partners from across academia and industry interested in CO2 capture, utilisation and storage (CCUS).
The project aims at accelerating and maturing the use of CCUS by developing, testing and demonstrating measurement, monitoring and verification technologies that can be used in most CO2 geological storage projects.
The team will be working with two existing facilities at Kizildere in Turkey and Hellisheidi in Iceland.
Led by Professor Sevket Durucan at Imperial College London, SUCCEED will run for three years and is funded by ACT, an international initiative to establish CCUS as a tool to combat global warming.
The objectives of the project are to:
- Research and demonstrate the feasibility of utilising produced CO2 for re-injection to improve geothermal performance, while also storing the CO2
- Develop further, test and demonstrate innovative monitoring technologies:
- New higher signal-to-noise ratio distributed fibre-optic acoustic sensing system (iDAS)
- New permanent and highly repeatable vibratory-type (environmentally friendly) seismic monitoring electric seismic-vibrators
- Test and demonstrate the industrial CCUS opportunity for geothermal field operators to:
- Maintain and enhance reservoir pressure as the driving mechanism for the geothermal fluid and improve geothermal performance,
- Increase reservoir permeability and productivity while suppressing scaling by artificial acidification
- Utilise advantageous operational field environments, facilitated by thermally and hydrologically active geothermal fields which are currently in production, for accelerated testing of CO2 utilisation, supercritical and dissolved CO2 injection, reactive transport and storage,
- Use a real field environment for the testing of supercritical and dissolved CO2 injection into a reservoir and provide the geothermal energy sector with the means to address the current climate change challenge through CO2 utilisation and storage.
The project aims to:
- Field test and implement of a new higher signal-to-noise ratio iDAS system and a new and novel vibratory-type electric seismic sources to provide layer-specific seismic monitoring capability for CCUS and geothermal applications.
- Accelerate testing and assessment of the effectiveness, and validation of a number of CO2 injection and plume monitoring techniques in carbonate reservoirs in the main.
- Gain further insights into the potential for injection induced seismicity in geothermal fields.
- Improve understanding of the fundamentals of field scale behaviour of injected supercritical and dissolved CO2 in geothermal reservoirs, and critical assessment of current theories.
- Develop strategies for pressure management in geothermal reservoirs through supercritical and dissolved CO2 injection and storage in order to extend the operational life of wells/fields with commercial benefits.
- Create a reliable techno-economic assessment method to assess the economic benefits of CCUS implementation in geothermal energy production.
- Develop a flexible and modular life cycle inventory model for geothermal CCUS implementation to enable the environmental assessment of the proposed technologies and support stakeholder communication.
- Develop and demonstrate an innovative CCUS technology to help accelerate CCS by opening it to an important CO2 emitting power sector.
