The research, whose primary goal was to gain a better understanding of the behaviour of injected CO2 in the sub-surface, was based on uncertainty analysis using simulations for leakage potential and capacity estimates for saline aquifers.
While the capacity simulations showed that there still remains large uncertainty when it comes to storage capacity estimates, the results for the leakage simulation looked rather different. According to the results, there is a certain probability of leakage. The actual amount of CO2 that leaks, however, is a matter of fractions of one percent of total injected volumes of CO2. In addition, it is in the scope of thousands of years that the leakage will eventually occur.
The complete thesis can be obtained from MIT`s website.
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.
In this news digest, we monitor events that impact the environment in the Russian Arctic. Our main focus lies in identifying the factors that contribute to pollution risks and climate change.
