“…Most of the recent scenarios related to the renewable energy transition, presented at the world level, forecast a significant reduction in carbon emissions across all sectors of energy use 1,2 . This is the reason why most European countries harness all their potential to raise the demand for electrical energy generation by renewable energy sources 3,4 .…”

The operating temperature increase in solar photovoltaic modules is a major problem, which affects their performance negatively. This numerical study introduces the effect of natural convection air‐cooling on the performance a novel hybrid photovoltaic/thermal collector. The standard k‐ε turbulence model is implemented for describing the turbulent natural convection. For improving the heat transfer rate of a novel photovoltaic/thermal collector system (PV/T), a sloped entrance channel (SEC) and an aluminum flat plate (AFP) were installed. The effects of SEC geometry parameters, the number of AFP and their distance to the photovoltaic module (PV) on the average Nusselt number are investigated. In addition, the effect of the PV/T system tilt angle and Rayleigh number on the thermo‐hydrodynamic flow behavior has been discussed. The results indicated that the heat transfer rate of the new hybrid PV/T system was improved by up to 20%, compared to the reference case without an aluminum flat plate. In addition, increasing the tilt angle of the PV/T system boosts airflow velocity, particularly for high Rayleigh number values (with and without AFP). Furthermore, several correlations, as functions of Rayleigh numbers and inlet channel dimensions, have been developed to predict the average Nusselt number.

Carbon dioxide displacement and storage is the most feasible technology to realize carbon neutralization, and also the key technology to improve the recovery of tight reservoirs. CO 2 capture and carbonization can be achieved by precipitation of potassium carbonate by using the "Ethanol + KOH" solution system. The reaction process in the solution system is affected by the ethanol concentration, resulting in different CO 2 carbonization amounts with the change of ethanol concentration. At the same time, the potassium-based acid salt generated by precipitation can react with water to complete the regeneration of ethanol. In this paper, experimental means are used to study the CO2 capture efficiency of the "Ethanol + KOH" system, monitor the ethanol content in the solution in real time, and screen out the best ethanol concentration suitable for the formation temperature. Add KOH to the solution, use the ethanol regenerated in the solution after carbonization reaction to carbonize again, and determine the maximum CO 2 capture of "ethanol + KOH". Based on the high temperature and high pressure core displacement device, the CO2 burial experiment after the injection of "Ethanol + KOH" solution was carried out to clarify the change rule of CO2 burial under the action of "Ethanol + KOH" system in low permeability cores. The research results show that "96% ethanol+3g KOH" can effectively capture CO 2 , and each capture will produce 4.56g precipitation on average. At the same time, after the core is saturated with "96% ethanol+3gKOH" solution, CO 2 is injected to generate sediment, and the core permeability decreases by about 15%. The research results of this paper prove that, compared with direct injection of CO 2 into the formation, injection of this system into the formation in advance can accelerate the CO 2 carbonization process, thus effectively improving the CO 2 burial efficiency.

“…For sustainable development, China is increasing green investment to reduce carbon emissions (Huang et al, 2021; Liu & Lee, 2021; Zhang, Zhang, et al, 2021) and has set a goal of carbon neutrality (Jiang et al, 2022; Wang & Lee, 2022). Most researchers have aimed to achieve it through different strategies like clean energy (Li & Haneklaus, 2022; Wang & Lee, 2022).…”

Carbon emission is a global issue, and China is facing many problems to resolve it, especially in emission‐generating companies (EGCs). To maintain sustainable development, it is necessary to reduce carbon emissions for the well‐being of society, and carbon neutrality can play an important role. With China targeting the goal of carbon neutrality to reduce carbon emissions, this research aims to bridge the gap in the literature by considering carbon neutrality instruments in a duopoly market. The study sets up a mathematical model of the duopoly game to achieve desired objectives and then applies a simulation‐based optimization technique to examine the mathematical model under different experiments. After manipulating various scenarios to find the optimal values of carbon neutrality instruments, the results indicate that green bond provision, emission tax, and emission quota play a vital role in carbon neutrality. Different combinations of carbon neutrality instruments reduce various levels of carbon emissions. We further show that a combination of emission tax upon EGCs plays a key role in reducing carbon emissions during the fifth scenario. In the second scenario, a combination of green bond provision and emission tax reduces carbon emissions, but is lower than the fifth scenario. This research offers a reference for policymakers to move towards carbon neutrality, and it is beneficial for the government to decide the optimal values of carbon neutrality instruments.
