Buildings are undergoing a metamorphosis, emerging as pivotal actors in the realm of electricity generation and consumption, with vast untapped potential for energy storage. However, current research is marred by a dearth of quantitative methodologies for assessing the existing virtual energy storage (VES) resources within building contexts.

Then, the VES potential of vehicle-to-home system and heat pumps and building thermal capacity are analyzed for winter electric heating in Beijing. The results show that VES system is capable of delivering a maximum equivalent charging power of 432.816 kW, a maximum equivalent discharging power of 385.376 kW, and an equivalent energy storage capacity of 2165.64 kWh.

However, the issue of high cost, poor environmental stability and toxic benzene-based solvents for preparation represent significant challenges for the efficient organic HTLs. In contrast, low-cost and environmentally friendly inorganic hole transport materials have garnered considerable attention due to their excellent carrier mobility and environmental stability. Herein, thermal evaporated inorganic manganese sulfide (MnS) thin films were prepared as HTL for full inorganic Sb<sub>2</sub>S<sub>3</sub> solar cell. The effects of post-annealing treatment on the structure, photoelectric properties of MnS films and device performance were investigated. The post-annealing treatment enables MnS HTL to exhibit high carrier mobility and suitable energy band matching characteristics, thereby suppressing the internal charge recombination and reducing the voltage loss in the device. This ultimately results in a high photovoltaic conversion efficiency (PCE) of 5.66%, which is more than a twofold increase in efficiency compared to that of device with unannealed MnS HTL. Furthermore, the optimal MnS HTL-based Sb<sub>2</sub>S<sub>3</sub> solar cell demonstrated superior environmental stability (around 5.59% degradation in 30 days), compared to that of device with organic Spiro-OMeTAD HTL (around 20% degradation in 30 days).

This process holds significant environmental and economic relevance, especially when high-purity methane and carbon dioxide can be simultaneously produced. In this regard, dual-reflux pressure swing adsorption (DR-PSA) emerges as a promising technology that achieves the separation objective. In this study, a numerical simulation model of a non-isothermal DR-PSA was established using the Aspen Adsorption simulation tool to evaluate the dynamics of the system for binary separation of biogas feed mixture containing 45 mol% CO<sub>2</sub> + 55 mol% CH<sub>4</sub>, using a CO<sub>2</sub>-selective silica gel as the solid adsorbent. The goal was to provide preliminary insights into the capability of the DR-PSA process (with silica gel) to produce two useful products, CH<sub>4</sub> and CO<sub>2</sub>, under typical biogas feed conditions. The behavior of the DR-PSA is described through pressure and temperature profiles within the bed column at cyclic steady-state conditions. The results indicate that, under preliminary unoptimized conditions, 86.0% of CH<sub>4</sub> could be recovered with a purity of 85.8% as a light product, whereas CO<sub>2</sub> enriched to 82.9% was achievable as a heavy product, with a recovery of 82.9%, using a pressure ratio, <em>P</em><sub><em>H</em></sub><em>/P</em><sub><em>L</em></sub> of 5.

This review examines the most recent BTMS that are based on HPs, with a particular emphasis on the role of artificial intelligence (AI) in optimizing thermal performance. It also addresses significant distinctions from prior research, including AI-driven predictive models and hybrid cooling techniques. A classification is created using various wick topologies, working fluids within a lithium-ion BTMS's temperature range, and their appropriate envelope materials. The instances of each one's application in the BTMS or potential uses in the future have been presented. HPs are divided into several categories depending on their form (tubular, flat, loop, etc.) and each variety is given thorough explanations, illustrations, and data on how it performed in various trials. Furthermore, extensive literature research reveals AI's role in fine-tuning operational parameters, crafting algorithms to predict core temperatures in HP systems, and employing advanced optimization and deep learning techniques for efficient and safe management of HP-cooled reactors under stringent power limitations. Moreover, hybrid cooling strategies, including air-cooled, liquid-cooled, phase change material (PCM) cooled, and thermoelectrically cooled HPs, are also highlighted.

However, the impact of disorderly charging and the potential of VGI considering random user behavior requires clarification. This paper established a mixed-integer linear programming model with user behavior simulated by the Monte Carlo algorithm. The travel and charging behavior of EVs are provided by Monte Carlo simulation with characteristic parameters from statistical data of urban vehicle travel data. A digital model describing the VGI charging boundary is built to restrict the transition from uncontrolled charging to VGI. Through analysis of the global optimization results, the comparison of disorderly charging with VGI under different scenarios is provided to illustrate the effectiveness of avoiding load uplift and reducing load peak-valley range.
