“…Under different leakage models, they found that CCS remains a valuable option even with CO 2 leakage of a few %/yr, which is well above the maximum seepage rates that are thought to be likely from a geoscientific point of view for well-chosen and well-designed CO 2 storage sites. The conclusions of van der Zwaan and Gerlagh [29] are in line with those reported in van der Zwaan and Smekens [30] based on the detailed bottom-up energy systems model MARKAL, but the former involve a higher allowable upper limit of leakage than the 0.5%/yr calculated in the latter.…”

“…Herzog et al [7] proposed a definition for the effectiveness of temporary CO 2 storage (through any means) involving the net present value of the total stream of avoided CO 2 emissions. In an update of earlier work on CCS with the DEMETER model, van der Zwaan and Gerlagh expanded this top-down integrated assessment model by implementing an effectiveness expression similar to Herzog et al [7] and applying it to geological storage of CO 2 in leaky reservoirs [5,29]. Under different leakage models, they found that CCS remains a valuable option even with CO 2 leakage of a few %/yr, which is well above the maximum seepage rates that are thought to be likely from a geoscientific point of view for well-chosen and well-designed CO 2 storage sites.…”

A major characteristic of our global interactive climate-energy system is the large uncertainty that exists with respect to both future environmental requirements and the means available for fulfilling these. Potentially, a key technology for leading the transition from the current fossil fuel-dominated energy system to a more sustainable one is carbon dioxide capture and storage. Uncertainties exist, however, concerning the large-scale implementability of this technology, such as related to the regional availability of storage sites for the captured CO 2 . We analyze these uncertainties from an integrated assessment perspective by using the bottom-up model TIAM-ECN and by studying a set of scenarios that cover a range of different climate targets and technology futures. Our study consists of two main approaches: (1) a sensitivity analysis through the investigation of a number of scenarios under perfect foresight decision making and (2) a stochastic programming exercise that allows for simultaneously considering a set of potential future states-of-the-world. We find that, if a stringent climate (forcing) target is a possibility, it dominates the solution: if deep CO 2 emission reductions are not started as soon as possible, the target may become unreachable. Attaining a stringent climate target comes in any case at a disproportionally high price, which indicates that adaptation measures or climate damages might be preferable to the high mitigation costs such a target implies.

“…Gas and oil fields are low cost storages because the injected CO 2 can be used to increase the total depletion of the fields. Risks are associated with all possible deposits: CO 2 may leak slowly or suddenly from the deposits [34,35] and thus either decrease the utility of CCS or even pose a risk to life. In the case of CO 2 storage in deep oceans, marine eco-systems may be affected negatively [36].…”

“…This study focuses on model outcomes versus leakage rate, while holding all other variables constant. Previous efforts to apply techno-economic analysis toward modeling CCS outcomes have considered leakage to varying degrees [9], [11], [47], [48]. Here, we go into further depth, looking at the dependence of global temperatures, global carbon abatement and sequestration, and gross world product to a wide range of leakage rates.…”

Carbon capture and sequestration (CCS) may play a key role in our energy future. However, the widespread sequestration of CO 2 into storage reservoirs is inhibited by safety and leakage concerns. Effective leakage monitoring at the surface is recently made possible by the development of quantum cascade (QC) laser-based sensors, which are capable of tracking fluxes in CO 2 isotope concentrations. In this paper, we initially discuss the status of this technology, including recent results from distributed feedback QC lasers for use in sensing CO 2 isotopic ratios. These lasers show single-mode emission at 4.32 µm, overlapping strong absorption resonances of 12 CO 2 , 13 CO 2 , and 18 OCO. We then consider the value of such devices for quantifying CO 2 leakage using a climate-economy integrated-assessment model that is modified to include CCS. The sensitivity of model outcomes to reservoir leakage is studied, showing that an average reservoir storage half-life on the order of 1000 years or longer can limit atmospheric temperature increases to 2°C or less over the next 150 years for economically optimal emissions scenarios. The present day economic value of CCS is established versus reservoir half-life, showing a significant return on investment (∼2 trillion U.S.$, or ∼4% of gross world product) when the average reservoir half-life is 250 years, with a sharp drop in the value of CCS technology for half-life values below 250 years. Quantifying CO 2 leakage rates via QC laser-based sensing will contribute greatly toward accurately assessing CCS technology and its efficacy as part of CO 2 limitation strategies.Index Terms-Environmental economics, laser applications, quantum cascade lasers, trace gas sensing.
