The paper ‘Onset of convection in a porous medium in the presence of chemical reaction’, which was published in the journal Physical Review E, may have implications for CO2 storage in saline aqufiers.
The research was conducted by the Department of Chemical Engineering and Biotechnology at the University of Cambridge. It showed that, depending on the strength of the reaction between dissolved CO2 and porous rock, distinct scenarios of CO2 movement may occur in deep saline rock formations. It is in theory possible to manipulate the strength of reactions, thereby engineering the movement of CO2, keeping it in one area or moving it to another within the aquifer.
– This research shows how rigorous mathematical analysis coupled with strong physical understanding can help us grasp the complex interactions of flow and reaction in a carbon reservoir. Such knowledge will be valuable in guiding future approaches to carbon storage, said project leader Dr. Silvana Cardoso, according to the Carbon Capture Journal.

Recent attacks on Ukraine’s Zaporizhzhia nuclear power plant "mark the beginning of a new and gravely dangerous front of the war," the UN atomic agency's director general said last week.
After years of inaction, Germany is working on its Carbon Management Strategy to resolve how CCS can play a role in climate action in industry. At the end of February, the Federal Ministry for Economic Affairs and Climate Action published first key points and a proposal to amend the law Kohlenstoffdioxid Speicherungsgesetz (KSpG). Bellona Deutschland, who was actively involved in the previous stakeholder dialogue submitted a statement in the association hearing.
In the midst of a global discussion on whether natural gas should be used as a transitional fuel and whether emissions from its extraction, production, transport and use are significantly less than those from other fossil fuels, Russia has developed ambitious plans to increase its own production of liquified natural gas (LNG) in the Arctic – a region with 75% of proven gas reserves in Russia – to raise its share in the international gas trade.
