“…If, however, the lowest and cautious case (efficiency of 2 per cent) is more accurate, the derived capacity of 65 Gt will only last less than a decade. To our knowledge, only Wei et al (2013) recommended such a low efficiency factor (2.7 per cent) for the national level. If low efficiency factors -which are used in about two third of all analysed studies (compare figure 2) -are confirmed in future research, it is debatable whether Chinese policy-makers should implement this technology as a major mitigation strategy for the power and industrial sector, considering its temporary nature.…”

China is very active in the research and development of CO 2 capture and storage technologies (CCS). However, existing estimates for CO 2 storage capacity are very uncertain. This uncertainty is due to limited geological knowledge, a lack of large-scale research on CO 2 injection, and different assessment approaches and parameter settings.Hence storage scenarios represent a method that can be used by policy makers to demonstrate the range of possible storage capacity developments, to help interpret uncertain results and to identify the limitations of existing assessments. In this paper, three storage scenarios are developed for China by evaluating China-wide studies supplemented with more detailed site-and basin-specific assessments. It is estimated that the greatest storage potential can be found in deep saline aquifers. Oil and gas fields may also be used. Coal seams are only included in the highest storage scenario. In total, the scenarios presented demonstrate that China has an effective storage capacity of between 65 and 1,551 Gt of CO 2 . Furthermore, the authors emphasise a need for action to harmonise storage capacity assessment approaches due to the uncertainties involved in the capacity assessments analysed in this study. Highlights:• China's CO 2 storage capacity varies considerably in existing estimates.• Assumptions must be transparent to enable all stakeholders to evaluate the results.• The storage scenarios yield a range between the maximum and minimum storage capacity.• Storage scenarios S1-S3 for China yield a capacity of 1,551, 402 and 65 Gt of CO 2 .

“…The database on individual oil fields was obtained mainly from the Atlas of Oil and Gas Basins in China (Li andLv, 1988, 2002), the geology database, Petroleum Geology of China (Chinese Petroleum Geology Editorial Committee, 1992;Zhai, 1987), and some other oil field data (Wei et al, 2013). The oil fields omitted in this study are likely to be similar with these oil fields evaluated.…”

a b s t r a c tCarbon dioxide enhanced oil recovery (CO 2 -EOR) and sequestration in depleted oil reservoirs is a plausible option for utilizing anthropogenic CO 2 to increase oil production while storing CO 2 underground. Evaluation of the storage resources and cost of potential CO 2 -EOR projects is an essential step before the commencement of large-scale deployment of such activities. In this paper, a hybrid techno-economic evaluation method, including a performance model and cost model for onshore CO 2 -EOR projects, has been developed based on previous studies. Total 296 onshore oil fields, accounting for about 70% of total mature onshore oil fields in China, were evaluated by the techno-economic method. The key findings of this study are summarized as follows:(1) deterministic analysis shows there are approximately 1.1 billion tons (7.7 billion barrels) of incremental crude oil and 2.2 billion tons CO 2 storage resource for onshore CO 2 -EOR at net positive revenue within the Chinese oil fields reviewed under the given operating strategy and economic assumptions. (2) Sensitivity study highlights that the cumulative oil production and cumulative CO 2 storage resource are very sensitive to crude oil price, CO 2 cost, project lifetime, discount rate and tax policy. High oil price, short project lifetime, low discount rate, low CO 2 cost, and low tax policy can greatly increase the net income of the oil enterprise, incremental oil recovery and CO 2 storage resource.(3) From this techno-economic evaluation, the major barriers to large-scale deployment of CO 2 -EOR include complex geological conditions, low API of crude oil, high tax policy, and lack of incentives for the CO 2 -EOR project.

“…CO 2 -EWR combines the CO 2 aquifer storage with underground water recovery. Water recovery is a necessary operating strategy of the large-scale CO 2 aquifer storage for pressure building-up mitigation [10]. CO 2 -EWR is one special case of CO 2 aquifer storage technology with purpose for water recovery.…”
