Passing Gas: Policy Implications of Leakage From Geologic Carbon Storage Sites

摘要: Publisher Summary Increasing attention is being given to injection of carbon dioxide (CO2) into geologic reservoirs as a management technique reduce releases greenhouse gases (GHG) the atmosphere. Among many issues that need be resolved for storage an effective GHG leak-rate performance system. Storage sites must designed avoid sudden releases, which could pose acute risks asphyxiation. The more complex challenge structure design strategy and oversight system not only has goal limiting slow leaks atmosphere de minimis level but also robust if we, or future generations, encounter less than perfect in real-world operation. To mitigation strategy, systems leak trivial amounts over time spans hundreds years. While individual can have varying rates without undermining effectiveness, whole close leak-free. One might think at first blush choice stabilization target would strongest driver maximum permissible long-term from However, annual global budgets targets between 450 750 ppm tend converge low levels within two three hundred This means cumulative amount stored during this period major influence on required system, regardless selected.
