Modelling the two-phase plume dynamics of CO2 leakage into open shallow waters
… and biological risk to the marine ecosystem from CO2 leakage from potential carbon storage locations around the North Sea. New sub-models are developed for bubble formation and drag coefficients using in-situ measurements from videos of the Quantifying and monitoring potential ecosystem Impacts of …

Surface Reactivity and Dissolution Rate of Galena: Potential Impact of CO2 Leakage from Geological Carbon Sequestration on Groundwater Quality
… is one promising solution to mitigating CO2 emissions and curtailing global

GEOCHRONOLOGY, GEOCHEMISTRY, AND TECTONIC CHARACTERIZATION OF QUATERNARY LARGE-VOLUME TRAVERTINE DEPOSITS IN THE SOUTHWESTERN UNITED STATES AND THEIR IMPLICATIONS FOR CO2 SEQUESTRATION
… carbonic groundwater due to the degassing of CO2. Travertine deposits are often situated along faults that serve as conduits for CO2-charged groundwater and their geochemistry often records mixing of deeply-derived fluids and volatiles with shallow meteoric water. Travertines are surface …

Implications of geological carbon sequestration on shallow freshwater aquifers geochemistry
… increase in atmospheric concentrations of CO2 over the last few centuries has led to development of various mitigation efforts aimed at preventing CO2 release into the atmosphere. The most promising mitigation technique, in terms of scale and storage potential, is geological carbon capture, …

Reduced-Order Modelling and Observations of Geological Carbon Dioxide Storage
Worldwide carbon dioxide (CO2) emissions targets are unlikely to be met without large scale geological CO2 storage, with much of the storage capacity found in saline aquifers. The key aim of carbon sequestration is the long-term or permanent storage of CO2 within the sub-surface, minimising the …

Electricity Generation Location and Benefits to Human Health: What health benefits can be attributed to RGGI in New Jersey, New York, and Pennsylvania?
… health gains, from the longest running U.S. CO2 control program. Further, it examines the patterns of electric generation to evaluate changes at regional and state levels, to better understand the potential of CO2 leakage, which is CO2 being emitted from generation that has moved from a …

Physiological and molecular determinants of the Chlamydomonas reinhardtii pyrenoid
… low availability and limited diffusion of CO2 in the aquatic milieu, and low affinity for CO2 by the primary carboxylating enzyme, Ribulose 1,5-bisphosphate carboxylase/oxygenase (RuBisCO). Many eukaryotic algae, and a single group of land plants, the hornworts, have an inducible carbon …

Fluid-rock interactions in a carbon storage site analogue, Green River, Utah
Reactions between CO2-charged brines and reservoir minerals might either enhance the long-term storage of CO2 in geological reservoirs or facilitate leakage by corroding cap rocks and fault seals. Modelling the progress of such reactions is frustrated by uncertainties in the absolute mineral …

Numerical Modeling and Simulation of Mineral Dissolution in Fractured Carbonate Formations
… processes including waterflooding, geological CO2 sequestration (GCS), and matrix acidizing in carbonate formations. Such a dissolution process could form the preferential pathways to cause a failure of waterflooding and GCS due to the early breakthrough of the displacing fluid and CO2 leakage, …

The maximum quantum efficiency of CO2 assimilation declines with depth in the canopies of the C4 crops Miscanthus x giganteus and Zea mays
Leakage of CO2 from bundle sheath cells of C4 plants (φ) could limit their productivity. φ is thought to increase at low light in the C4 crop Miscanthus x giganteus (M. x giganteus) (Kromdijk et al., 2008). This should reduce photosynthetic light use efficiency (PLUE) in the lower canopy. Zea mays …

Modeling CO₂ leakage from geological storage formation and reducing the associated risk
… and faults, which can act as pathways for leakage of stored CO₂ Modeling the flux of CO₂ along a leaky pathway requires transport properties along the pathway. We provide an approach based on the analogy between the leakage pathway in wells that exhibit sustained casing pressure (SCP) and …

CO2-rock interaction during CO2-enriched brine injection into storage reservoirs using NMR integrated with fiber optic sensors
… contributor to global warming. The mitigation of CO2 emissions into the atmosphere is therefore critical, where new technologies need to be urgently developed and employed on a large scale. One promising method is to capture anthropogenic CO2 and store it in geological formations, e.g. depleted …
