Earlier studies by scientists Christine Ehlig-Economides and Michael Economides have questioned whether carbon dioxide storage is feasible with the amount of pressure created. Scientists from The Berkeley Lab refute this, saying that the studies only consider storage in closed storage reservoirs.
Lead Berkeley Lab researcher Quanlin Zhou studied full-scale deployment scenarios with open, partly open and closed storage reservoirs. The conclusion is that in open and partly open systems the pressure build up is relieved naturally by movement of native saline waters into regions far away from where carbon dioxide injection occurs. The study also concludes that pressure management strategies may feasibly be undertaken to relieve a pressurised system.
– This investigation furthers our understanding of the extent and magnitude of pressure build-up induced by large-scale underground carbon storage. Using natural open and partially open formations will help attenuate such pressure build-up to a manageable degree, said Zhou according to Science Daily.
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.
