Summary: In this study, glycol ether-functionalized imidazolium, phosphonium, and ammonium ionic liquids containing acetate (OAc-) or Tf2N- anions were designed. These task-specific ILs were found to have the capability to solubilize up to 0.55 mol CO2 per mole of IL (or 5.9 wt% CO2) at room temperature and atmospheric pressure. While acetate anions provided better CO2 capture, Tf2N- anions were more compatible with alcohol dehydrogenase (ADH), a key enzyme involved in the enzymatic conversion of CO2 to methanol. These promising results suggest the possibility of capturing and enzymatically converting CO2 under ambient pressure.

Summary: This study investigates the effect of CO2 injection pressure on gas migration characteristics and coalbed methane (CBM) extraction. Experimental tests were conducted using a CH4 to CO2 replacement platform under different CO2 injection pressures. The results indicate that gas migration rate increases with higher injection pressure, and CH4 desorption rate and coal seam permeability display different stages of decline and stability. Higher injection pressure leads to increased CH4 desorption volume and CO(2) sequestration volume, and improved CH4 extraction efficiency. These findings are of great importance for optimizing CO2 injection pressure and enhancing CBM extraction.

Summary: In this study, reservoir simulations were conducted to investigate the impact of CO2 hydrate formation on CO2 storage capacity in shallow gas fields. Results showed that the formation of CO2 hydrate moderated the reservoir pressure, allowing for a significantly higher storage capacity of CO2. The storage capacity increased by up to 3.2 times in gas fields with CO2 hydrate formation compared to those without. The initial water saturation had an effect on the storage capacity, with an increase up to a certain point and then a decrease. Screening results identified several gas fields in Alberta with high CO2 storage capacity, including Chard and Saleski gas fields.

Summary: This paper investigates the opportunities to use carbon capture and storage (CCS) in Vietnam's power and industry sectors to reduce carbon emissions. The results show that Vietnam's power sector emits 136 Mtpa CO2 and the industry sector emits 88 Mtpa CO2. The nearby sedimentary basins have sufficient storage capacity to store 831 years of CO2 emissions. Additionally, there is potential for CO2 enhanced oil recovery and enhanced gas recovery, which could recover 1058 MMbbl and 95 MMbbl of oil from oil fields and gas fields, respectively. The study proposes establishing four CCS hubs to connect regional CO2 sources and sinks, which could remove up to 142 Mtpa CO2 or 64% of Vietnam's stationary emissions.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
