Ocean crust pillow lavas could store many centuries of industrial CO2
:: University of SouthamptonResearchers from the University of Southampton have identified regions beneath the oceans where the igneous rocks of the upper ocean crust could safely store very large volumes of carbon dioxide.
The burning of fossil fuels such as coal, oil, and natural gas has led to dramatically increasing concentrations of CO2 in the atmosphere causing climate change and ocean acidification. Although technologies are being developed to capture CO2 at major sources such as power stations, this will only avoid further warming if that CO2 is then safely locked away from the atmosphere for centuries.
PhD student Chiara Marieni, who is based at the National Oceanography Centre, Southampton, investigated the physical properties of CO2 to develop global maps of the ocean floor to estimate where CO2 can be safely stored.
