Extinct Offshore Volcano Could Store Gigatons of Carbon Dioxide
Carbon dioxide (CO2) emissions are a major contributor to climate change, and scientists have been searching for ways to reduce the amount of CO2 in the atmosphere. One potential solution is carbon capture and storage (CCS), which involves capturing CO2 emissions from power plants and other industrial sources and storing them underground. Now, researchers have discovered an unlikely location for CCS: an extinct offshore volcano.
The Discovery
Scientists from the University of Edinburgh and the Scottish Association for Marine Science have discovered that an extinct volcano off the coast of Scotland could store gigatons of carbon dioxide. The volcano, known as the Captain Field, is located in the North Sea and was active around 50 million years ago. The researchers used seismic imaging to map the structure of the volcano and found that it has a large, porous layer of rock that could be used to store CO2.
How It Works
The idea behind CCS is to capture CO2 emissions from power plants and other industrial sources before they are released into the atmosphere. The CO2 is then transported to a storage site, where it is injected into a deep underground formation. The formation must be porous enough to hold the CO2, but also impermeable enough to prevent it from leaking back into the atmosphere.
The Captain Field volcano has a layer of rock that meets these requirements. The layer is made up of volcanic ash and lava flows that have been compacted over millions of years. The rock has tiny pores that can hold CO2, but it is also impermeable enough to prevent leakage.
The Benefits
Storing CO2 in offshore volcanoes like the Captain Field could have several benefits. First, it would provide a new location for CCS that does not require drilling into deep underground formations on land. Second, offshore storage sites could potentially hold much larger amounts of CO2 than onshore sites. Finally, storing CO2 in offshore volcanoes could help to reduce the risk of earthquakes and other geological disturbances that can occur when injecting CO2 into deep underground formations.
The Challenges
While storing CO2 in offshore volcanoes has potential benefits, there are also several challenges that must be addressed. First, the technology for injecting CO2 into offshore formations is still in the early stages of development. Second, there are concerns about the long-term stability of offshore storage sites and the potential for leakage. Finally, there are regulatory and legal issues that must be addressed before CCS can be implemented on a large scale.
Conclusion
The discovery of an extinct offshore volcano that could store gigatons of carbon dioxide is an exciting development in the search for solutions to climate change. While there are still many challenges to overcome, the potential benefits of storing CO2 in offshore formations like the Captain Field are significant. As research continues, it is possible that CCS could become a key tool in the fight against climate change.
