The CarbonNet Project is investigating the potential for a capture and storage network with capacity for sequestering up to 125 million tonnes of CO2 over 25 years. As part of the storage approval there is a legislative requirement for CCS activities in Australia to have in place a robust monitoring, measurement and verification (MMV) program.
CSIRO, as part of ANLEC R&D funded MMV Project 7-0816-305, ‘Methodology to deploy shallow-focused subsea CCS technologies’, has been testing the use of fixed and mobile platforms to provide recommendations on accurate and cost-effective MM&V methods. These methods are for measuring and attributing small changes in dissolved CO2 and gas bubbles in the water column in a shallow-coastal system. An alternative platform option for MMV currently not in the scope of the existing project is a cabled observatory system concept.
This project aims at delivering a feasibility and design study for integrating the sensor technologies proven during the ANLEC R&D MMV project into a cabled observatory concept. The goal of this research is to provide CarbonNet with several options that will permit robust and cost-effective MMV plan to be developed. This project would seek to understand engineering constraints, data processing requirements and a suite of sensors and platforms that could be employed for such a solution. In addition, the project results would contemplate the design of these systems and provide a reference case for future CCS monitoring options.
