The opinion article published in the Proceedings of the National Academy of Sciences of the United States (PNAS) seeks to cast doubt on the safety of CO2 storage. The authors highlight the importance of considering seismic activity for siting, permitting and managing CO2 storage sites and arrive at a very pessimistic conclusion about the achievable safety. As pointed out by Hill in his rebuttal, the researchers fail to fully account for the multiple geologic storage options that when taken together indicate a much more optimistic outlook of long-term safety of CO2 storage.
Over 1 billion tonne of CO2 has already been safely injected into depleted oil fields for enhanced oil recovery in the United States since the 1970’s. According to the National Energy Technology Laboratory, at least 20 billion additional tonnes of CO2 could be injected into such fields. These projects, along with other CO2 injection projects globally, are closely monitored for any resulting seismic activity. To date, none has been reported.
At Bellona we fully recognise the importance of seismicity and careful selection of suitable sites for CO2 storage. We appreciate the Stanford researchers bringing attention to this issue, but strongly disagree with their conclusions about the pessimistic outlook of geologic CO2 storage.
Even more research is needed in this topic, but the evidence is already there. We are convinced by the potential of CCS to be a safe and sustainable solution for dramatically reducing CO2 emissions globally.
A survey of events in the field of nuclear and radiation safety relating to Russia and Ukraine.
Russian president Vladimir Putin has told the United Nations atomic energy watchdog that Russia plans to restart Ukraine’s embattled Zaporizhzhia nuclear plant, currently occupied by Russian troops and technicians, fueling worries about a serious nuclear accident on the front lines of a grinding military conflict.
Wednesday, April 10, 2024 | Brussels, Belgium – Today, the European Parliament approved the newly revised Construction Products regulation (CPR)...
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.
