“…124 Improvement of AAILs for CO 2 capture can be achieved by increasing the number of active sites on the anions and reducing the viscosity. 125 The effect of cation on CO 2 absorption of AAILs appears to be small, with ammonium AAILs slightly better than phosphonium ILs. This subtle difference is likely due to the steric hindrance caused by longer alkyl chains of phosphonium ions.…”

“…More specifically, the conversion process at the anode side begins with the biomass oxidation by POM to form a reduced POM complex (H-POM), while water molecule also serves as a proton (H + ) donor in this process according to the reaction: Bio-mass+H 2 O+POM→Oxidized products+CO 2 +H-POM. Note that the byproduct CO 2 can be captured and absorbed by low-cost hydroxide adsorbents or ionic liquids, and applied to the energy industry such as methane production and enhanced oil recovery [22], [29]. Then, the reduced H-POM can be readily reoxidized at anode surface driven by the applied electric field.…”

Under the pressure of climate change, the demands for alternative green hydrogen (H2) production methods have been on the rise to conform to the global trend of transition to a H2 society. This paper proposes a multi-renewable-to-hydrogen production method to enhance the green H2 production efficiency for renewable-dominated hydrogen fueling stations (HFSs). In this method, the aqueous electrolysis of native biomass can be powered by wind and solar generations based on electrochemical effects, and both electrolysis current and temperature are taken into account for facilitating on-site H2 production and reducing the electricity consumption. Moreover, a capsule network (CN)-based H2 demand forecasting model is formulated to estimate the gas load for HFS by extracting the underlying spatial features and temporal dependencies of traffic flows in the transportation network. Furthermore, a hierarchical coordinated control strategy is developed to suppress high fluctuations in electrolysis current caused by volatility of wind and solar outputs based on model predictive control (MPC) framework. Comparative studies validate the superior performance of the proposed methodology over the power-to-gas (P2G) scheme on electrolysis efficiency and economic benefits.

“…CO 2 absorption with chemical solvents, typically aqueous amine solutions, is the most widely deployed technology used for carbon dioxide separations, however it requires large amounts of energy to regenerate the solvent. The exceptional intrinsic qualities of ionic liquids (ILs), such as negligible volatility and 'designer-solvent' property tunability, have motivated their study for CO 2 separations (for recent reviews see, e.g., [1][2][3][4]). Likewise, deep eutectic solvents (DESs) have also been examined for these separations (see, e.g., [5][6][7][8][9][10] for recent reviews).…”

Classical molecular dynamics simulations were used to study the separation of carbon dioxide from methane by three formulations of the deep eutectic solvent (DES) ethaline (choline chloride: ethylene glycol at 1:2, 1:4 and 1:8 molar ratios), in the bulk and confined inside carbon and titania slit pores of two different pore widths, 2 nm and 5 nm. The highest permselectivities (~20) are observed for 1:2 ethaline in a 5 nm carbon pore, followed by the 1:4 DES in a 5 nm graphite pore, 1:2 ethaline in a 2 nm carbon pore and the 1:8 bulk DES. Our results indicate that variations in the ratio of ethylene glycol, which in turn affect the interactions of all DES species with the gas molecules and the different pore walls, plus confinement effects resulting from varying the pore sizes, can affect the gas separation performance of these systems in complex ways.
