"The study explored the wide range in #CDR deployment volumes across 1.5ยฐC compatible & high overshoot pathways by evaluating the links btw CDR & conceptually linked scenario aspects, via focus on CDR in 2050 & scenario properties related to reaching #NetZero CO2."
๐งต
"#CDR volumes
were further evaluated in terms of their relative and absolute contribution to total mitigation up until reaching
net-zero CO2, showing considerable variation across scenarios with a median relative contribution of around 20%." 2/7
"The volumes of #CDR in 2050 and 2100 and the cumulative amount throughout the 21st century were most strongly correlated to the degree to which CO2 emissions are reduced as a means of reaching net-zero CO2." 3/7
"The volume of #CDR in 2050
is also substantially correlated to the timing of #NetZero CO2." 4/7
"The robustness of the analyzed relationships was evaluated by comparing different scenario filtering and data-cleaning approaches." 5/7
"Beyond filtering and cleaning, additional factors that influence #CDR deployment in scenarios, such as discount rates, carbon price trajectories, and scenario design choices," were also discussed in this study.

"This investigation was done by performing numerical simulations of coupled multiphase flow and geomechanics on a representative field-scale #geological model in the Gulf of Mexico that could become a typical CO2 #storage site."
2/9
Authors use "representative model to examine 2 potential hazards associated with large-scale CO2 storage:
๐ธCO2 might migrate to shallower formations
๐ธCO2 injection might induce seismicity due to destabilization of pre-existing faults." 3/9

"The system design is elegant in its ability to overcome key technical challenges and highlights the potential for using existing infrastructure to lower #DirectAirCapture cost and land footprint, and secure utilities and public confidence." 2/6
"The techno-economic analysis suggests a cost-of-capture of $100 per metric tonne of CO2 is feasible, allowing #geothermal facilities to increase their net profit by $29 per metric tonne of CO2 captured โ or $6 million per year โ under the 45Q tax credit." 3/6
"The recent paper aims to highlight key operational challenges related to #CO2#Injection in low-temp environments at various pressures."
So, a new approach is provided "to assess injectivity impairment phenomena, & their remediation at the lab scale."

"A novel core flooding-based testing apparatus was used to reckon permeability changes of porous core medium during injection of #CO2 across a range of saturations/T/P. This shows the effect on injectivity of
formation-damage mechanisms, including formation of CO2ย hydrates."
2/11
"The new dynamic dual-phase injection test rig was designed, built, and used in this study to assess a range of conditions expected during #CO2ย #injection either into deep saline aquifers or depleted oil and gas reservoirs."

Various conclusions were drawn in the review which are enlisted below:
1๏ธโฃ "The alkalinity of the ocean creates a massive increase in the oceanโs capacity to #store#carbon, relative to a scenario without #OceanAlkalinity."
2/14
2๏ธโฃ "Ocean warming causes decreases in both #CO2#solubility and the Revelle factor (B), which make the ocean less efficient at #absorbing CO2."
