Offshore CO2 Storage

Detailed overview of innovation with sample startups and prominent university research


What it is

Offshore CO2 storage involves capturing carbon dioxide emissions from various sources, transporting them to offshore locations, and injecting them into deep geological formations beneath the seabed for permanent storage. This approach utilizes depleted oil and gas reservoirs, saline aquifers, and other suitable geological structures found offshore to store CO2 securely and prevent its release into the atmosphere.

Impact on climate action

Offshore CO2 Storage presents a pivotal solution in mitigating climate change by securely sequestering carbon emissions beneath the ocean floor. By safely containing CO2, it prevents its release into the atmosphere, effectively reducing greenhouse gas levels and advancing global efforts towards a more sustainable future and climate action.

Underlying
Technology

The success of offshore CO2 storage relies on a complex interplay of technologies and scientific concepts:

  • Geological Characterization: Comprehensive geophysical surveys, including seismic imaging and seabed mapping, are crucial for identifying suitable storage sites and assessing their capacity, permeability, and geological integrity.
  • Reservoir Modeling and Simulation: Advanced computer models are used to simulate the injection process, predict the long-term behavior of CO2 within the storage formation, and assess potential risks associated with leakage or induced seismicity.
  • Well Engineering and Injection Technologies: Specialized well designs and injection technologies are crucial for safely and efficiently injecting CO2 into deep sub-seabed formations, ensuring the integrity of the wellbore and optimizing CO2 distribution within the reservoir.
  • Monitoring and Verification: Continuous monitoring systems, including seabed sensors and geochemical tracers, are used to track the movement of CO2 within the storage formation, verify its containment, and detect any potential leaks.
  • Environmental Impact Assessment: Thorough environmental impact assessments are conducted to evaluate the potential ecological effects of offshore CO2 storage on marine ecosystems, ensuring responsible and sustainable practices.
