Summary: This study presents a process simulation model in Aspen Plus (R) and a techno-economic assessment for the anaerobic digestion of Cuban sugarcane vinasses. It found that the electricity production biogas application (S_1) showed the best economic performance, with the mean electricity price leading to a net present value of zero being 90 USD/MWh. The recommendation is for Cuban plants to increase their capacities significantly or implement centralized biomethane production to ensure project profits.

Summary: The volume of ethanol production waste-molasses waste in Ukraine reaches up to 4 million m(3) per year and is causing environmental pollution. The development of an effective technology for using molasses in biogas plants to obtain energy gas-biogas is urgently needed. The goal of this study was to determine the optimal volume of molasses bard loaded into the methane tank in a quasi-continuous mode to maximize biogas production. Experimental studies were conducted on a laboratory biogas plant to determine the maximum biogas output based on different molasses compositions. The results showed that adding 10.5% and 26.1% molasses to cattle manure resulted in the highest biogas output under the periodic loading system. Adding molasses in the amount of 30% of the substrate volume based on cattle manure is recommended to increase biogas production.

Summary: Anaerobic digestion is a versatile technology that can produce biogas for various energy demands. Brazil has great potential for biogas production, but currently only a small percentage is utilized. This article reviews the technologies for biogas production and utilization in the context of sugarcane biorefineries. The study found that connecting steam boilers to electricity generators can achieve high thermal efficiency, and a portion of vinasse can meet the diesel consumption of agricultural operations. The aim of this review is to strengthen the research on biogas systems to align with the expansion and diversification of the Brazilian energy matrix.

Summary: An experimental study was conducted to investigate the combustion and emission characteristics of a common-rail four-cylinder diesel engine using CH4, CO2, and H-2 mixtures. The results showed that coating the pistons enhanced combustion characteristics, while slightly affecting BSFC and emissions. Gaseous fuel operations exhibited higher in-cylinder pressure and earlier combustion starting compared to diesel fuel, with hydrogen introduction reducing HC emissions and CO2 emissions.

Summary: This study conducted a techno-economic analysis comparing two types of thermophilic anaerobic reactors and three biogas utilization schemes. The results showed that the Fixed Bed Reactor (FBR) produced twice as much biogas as the Continuous Stirred Tank Reactor (CSTR) under the same conditions. The economic analysis indicated that co-firing in existing boilers by fuel-oil replacement and partial substitution of coal was more economically attractive than electricity production at the current electricity pricing in Indonesia.

Summary: Brazil faces water scarcity issues, particularly in the northeast region. Installing desalination plants using incineration as an energy source is a possible solution, but alternative energy technologies are needed. Energy analysis showed incineration alone cannot provide sufficient energy for desalination, but with municipal consortia and government incentives, costs can be reduced significantly.

Summary: Hydroelectric power plants in Brazil have lost competitiveness to wind and solar power due to a water crisis and depleted reservoirs. However, using Pumped Hydropower Storage (PHS) in combination with solar and wind resources could help recover water levels and improve economic performance. Energy calculations show that PHS could generate 1692 MWh/day of energy, but an additional 2729 MWh/day is needed to store the generated energy. Economic studies indicate viability for PHS scenarios I and III, but scenario II is unviable and controversial.

Summary: Electricity demand in Benin has been increasing due to population growth, and the government aims to boost renewable energy production to address energy deficits and ensure electricity access for all by 2035. However, despite the country's potential for renewable energy, it can only supply a small fraction of its energy needs, leading to increased electricity imports. Benin has seen a significant increase in solar power generation, but only a limited number of inhabitants have access to electricity. Additionally, Benin is the largest consumer of oil products and an electricity importer within the West African Economic and Monetary Union (WAEMU).

Summary: The anaerobic digestion process produces renewable fuel biogas and digestate as a by-product. The use of mineral additives improves biogas production, but their chronic effects on digestates are not well studied. This research analyzes the chronic effects of digestates from swine manure with and without iron ore tailings on the survival and reproduction of Enchytraeus crypticus. The findings suggest that the metals in digestates might have a synergistic effect on the organisms' survival and reproduction, but further analysis is needed to understand the toxicity under different climate conditions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
