Summary: CPG-F facility can generate more power than CPG power plant, but with less daily energy production. The capital cost of a CPG-F facility designed for varying durations of energy storage is 70% higher than a CPG power plant, but costs only 4% to 27% more than most CPG-F facilities designed for a specific duration, producing significantly more power than a CPG power plant.

Summary: Proper design of a solar-driven photothermal catalytic reactor is proposed, which enables efficient CO2 reduction into solar fuels. A comprehensive numerical model, considering light harvesting, energy and mass transfer, and chemical conversion processes, is developed to analyze the effectiveness of the reactor and obtain the optimal design strategy. Methods are suggested to enhance the chemical reaction by controlling parameters such as light capture, radiation transfer, temperature field, and reactant supply in the catalyst layer. The designed reactor demonstrates outstanding catalytic performance with remarkable light absorptivity, energy confinement, and reactants enrichment characteristics.

Summary: The researchers have developed a tubular-shaped nitrogen-boron-carbon catalyst (C-BN@600) derived from an ionic liquid and metal-organic framework composite, which was used as the cathode catalyst in a rechargeable zinc-carbon dioxide battery. The C-BN@600 catalyst exhibited excellent activity for electrochemical CO2 reduction to methanol with a Faradaic efficiency of 74% and a yield rate of 2665 μg h-1 mg-cat.1. The battery continuously consumes CO2 and electrochemically converts it to methanol during discharge, while simultaneously generating electrical energy, demonstrating a high energy density of 330 Wh kg-1 and a power density of 5.42 mW cm-2. It maintained stability for more than 12 days (>300 h, 800 cycles) at 1 mA cm-2, offering a dual-purpose platform for CO2 reduction and energy storage.

Summary: This study examines the relationship between carbon dioxide emissions per capita, economic complexity index, renewable energy, and inward foreign direct investment in the BRICS countries from 1995 to 2020. The findings confirm the existence of the environmental Kuznets curve, indicating a positive but decreasing impact of economic development on environmental deterioration, with the potential for achieving CO2 emissions neutrality in the long term. Additionally, the study supports the Pollution Haven Hypothesis, suggesting that BRICS economies choose to prioritize economic growth over environmental protection. The results also indicate the potential of Industry 4.0 technologies in contributing to the neutrality of polluting emissions.
