In a bid to curb greenhouse gases in the atmosphere of which CO2 is prominent, research carried out by a team of scientists at Peking University has led to a breakthrough finding. The research shows that liquid CO2 could be safely isolated in deep sea sediments which might help with Global Warming. As revealed in the paper published in Science Advances, the research team detailed the model that was built to showcase CO2 injections under the ocean floor and what it exhibited.
Coal-powered Power Plants Mainly Responsible for CO2 Emissions
As continued discharge of greenhouse gases in the atmosphere continues to heat up our planet and might help with Global Warming, scientists are looking for alternate places to stow them. Carbon dioxide has been identified as one of the leading greenhouse gases, which has led to efforts to curb its release. While some efforts are focused on looking for ways to prevent its release, some others are aimed at ways to capture and store it not to leak in the atmosphere.
The sediments beneath the ocean is one such place to store CO2. The finding is yet to be established if such a site could hold CO2 without leaking into water, and eventually in the atmosphere. For the study, researchers constructed a model to imitate ocean floor sediment conditions and what it might lead to if liquid CO2 was injected into it.
Among various sources, coal-burning power plants are mainly responsible for release of CO2 in the atmosphere. To curb this, initiatives are undertaken to find ways to trap the CO2 in these emissions. Such initiatives reveal that CO2 can be trapped and converted into different states, for example, from solid to liquid.
