Techno-socio-economic analysis of geological carbon sequestration opportunities

Abstract

Although geological carbon sequestration is considered one of the pillars required to achieve the goals of the Paris Agreement, only a few demonstration sites are currently being developed around the...

Upcoming Transformations in Integrated Energy/Chemicals Sectors: Some Challenges and Several Opportunities

“…Although variations exist, all approaches identified to achieve the goals of the Paris Agreement require long-term sequestration of CO 2 via geological repositories. 63 Although this final stage closes the carbon cycle initiated with hydrocarbon extraction, it should be noted that, in the realization shown in Figure 5, the cycle would only close after millions of years, when and if the sequestered CO 2 is reduced to hydrocarbons. 64 In each of the stages broadly identified in Figure 5, aggressive research and development programs have contributed to the long-term success of both the energy and chemicals industries for many generations.…”

“…76 State of the art and fundamental challenges: This approach is currently applied in several field sites, for example related to geological storage of CO 2 . 77 Nevertheless, to increase efficiency, it is required to quantify phenomena that occur within porous systems and change fluid properties significantly compared to bulk counterparts. Once quantified, these properties could be included in reservoir simulators to predict and derisk the future development of a petroleum reservoir.…”

“…These strategies require various combinations of low-carbon-energy supplies, reduced energy use, efficient operations, and CO 2 removal. Although variations exist, all approaches identified to achieve the goals of the Paris Agreement require long-term sequestration of CO 2 via geological repositories . Although this final stage closes the carbon cycle initiated with hydrocarbon extraction, it should be noted that, in the realization shown in Figure , the cycle would only close after millions of years, when and if the sequestered CO 2 is reduced to hydrocarbons …”

Mesoscale Simulations Reveal How Salt Influences Clay Particles Agglomeration in Aqueous Dispersions

“…For example, clay minerals (e.g., smectite, kaolinite, Illite, and chlorite) are thought to be responsible for formation damage in sandstone reservoirs . Indeed, clay particles can agglomerate, deposit, and block pore throats, ultimately affecting hydrocarbon production as well as access to the pore space in geological carbon sequestration projects. , …”

“…10 Indeed, clay particles can agglomerate, deposit, and block pore throats, ultimately affecting hydrocarbon production as well as access to the pore space in geological carbon sequestration projects. 11,12 The prediction of particle agglomeration into self-assembled structures has been addressed by several coarse-graining approaches. Indeed, coarse-grained (CG) molecular dynamics is emerging as a powerful tool to study large-sized and complex systems for time scales of up to milliseconds.…”
