Abstract

Carbon capture, utilization, and storage (CCUS) is an important pathway that can effectively reduce CO2emissions, and the convective mixing phenomenon driven by a density difference in CO2brine reservoir storage is very important for long-term storage. In this study, the convective mixing process of CO2and brine under a series of reservoir conditions was investigated by high-pressure Hele-Shaw cell experiments and numerical simulations. The effects of pressure and salinity on the convective mixing characteristics were explored. The number of fingers increased to the peak and then decreased with small fluctuations. Then, the patterns of variation in dissolution concentration, dissolution rate, and density parameters over time were obtained. The density of the mixed solution and the concentration of dissolved CO2both increased with time. Higher pressure promotes convective mixing, and the increase in salinity rather inhibits the convective mixing to proceed. At a pressure of 8.5 MPa and a salinity of 10 g/L, the density difference as a driving force of convective mixing is the largest; therefore, the process is the fastest. Additionally, the numerical simulation modeled the convective mixing process and clearly showed the flow state of each fluid, with most of the fingers moving downward and the brine moving upward, with boundary effects affecting the fluid at the boundary. The numerical simulations also produced quantitative analysis results, which agreed with the experimental data. This study provides a more detailed understanding of the CO2convection mixing process under reservoir conditions, which has positive implications for the development of CCUS technology.

Abstract

Summary: The conquest of land by plants was concomitant with, and possibly enabled by, the evolution of three‐dimensional (3D) growth. The moss Physcomitrium patens provides a model system for elucidating molecular mechanisms in the initiation of 3D growth. Here, we investigate whether the phytohormone ethylene, which is believed to have been a signal before land plant emergence, plays a role in 3D growth regulation in P. patens.We report ethylene controls 3D gametophore formation, based on results from exogenously applied ethylene and genetic manipulation of PpEIN2, which is a central component in the ethylene signaling pathway.Overexpression (OE) of PpEIN2 activates ethylene responses and leads to earlier formation of gametophores with fewer gametophores produced thereafter, phenocopying ethylene‐treated wild‐type. Conversely, Ppein2 knockout mutants, which are ethylene insensitive, show initially delayed gametophore formation with more gametophores produced later. Furthermore, pharmacological and biochemical analyses reveal auxin levels are decreased in the OE lines but increased in the knockout mutants.Our results suggest that evolutionarily, ethylene and auxin molecular networks were recruited to build the plant body plan in ancestral land plants. This might have played a role in enabling ancient plants to acclimate to the continental surfaces of the planet. [ABSTRACT FROM AUTHOR]
