This study provides a comprehensive assessment of solar energy integration and fuel efficiency optimization in the Bushehr Commercial Port, addressing a critical research gap in sustainable maritime logistics. While global trade has intensified port energy demand, existing studies lack a comprehensive assessment of operational energy efficiency in commercial ports. This paper introduces an innovative framework that quantifies the technical benefits of solar photovoltaic (PV) systems in port operations. Using pv syst software, including solar radiation analysis and port-specific energy assessments, the study shows that the deployment of 6336 PV panels, each with a power of 585 W, results in a total installed capacity of 3707 kWh. The system exhibits an annual energy generation rate of 7385,951 kWh with a performance ratio (PR) of 83.92 %, indicating high operational efficiency. Furthermore, the analysis of fossil fuel consumption shows significant seasonal fluctuations, with peak diesel consumption exceeding 10,578,132 liters in February due to increased operational demand, while the summer months show lower consumption. The findings highlight the critical role of solar photovoltaics in reducing seaports’ dependence on conventional fuels, thereby reducing greenhouse gas emissions and operating costs. This paper contributes to the strategic transition towards low-carbon port infrastructure and provides a replicable model for implementing sustainable energy in maritime hubs with high solar potential. Future research should focus on long-term energy resilience and optimization strategies for long-term outage scenarios.

Increasing emissions in the mobility sector pose a significant challenge for modern society, contributing extensively to climate change. One promising approach to mitigating these emissions is the development of CO₂-based alternative fuels, which can reduce dependence on fossil fuels, such as gasoline and diesel, by capturing and reusing CO₂ emissions. While the technical feasibility of these fuels has been widely studied, limited research exists on consumer preferences regarding how information about alternative fuels is communicated. Understanding communication preferences is essential and critical for designing effective communication strategies that foster public acceptance and adoption, as they shape how individuals process information, form attitudes, and ultimately decide whether to adopt sustainable technologies. To address this gap, an online survey study (N = 215) was conducted to explore laypeople’s perceptions of alternative fuels, focusing on their information needs and communication preferences. The results revealed two distinct consumer clusters with differing expectations for content, channels, and trusted sources of information and communication. One group preferred detailed, science-based information from institutions, while the other favored accessible, practice-oriented content from industry or media. These findings emphasize the need for tailored communication strategies that reflect varying trust dynamics and information preferences. They offer practical guidance for policymakers and industry actors aiming to increase public engagement and acceptance of CO₂-based alternative fuels.

The present research work is related to the optimization of a hybrid renewable energy system, combining Waste-to-Energy (WTE) and Photovoltaic (PV) technologies for hydrogen production by means of water electrolysis in both on-grid and off-grid operation modes. A WTE plant of 3 MW rated capacity is combined with a PV array of capacity varying from 0.5 to 3 MW. The Particle Swarm Optimization (PSO), Genetic Algorithm (GA), Simulated Annealing (SA), Gradient Descent, and Newton's Method algorithms were used to minimize Levelized Cost of Hydrogen (LCOH) while ensuring energy reliability. In the on-grid scenario, the minimum LCOH of around -399.215 $/kg was achieved by PSO, GA, and SA, which indicates cost-effectiveness with the help of grid exportation and importation. Whereas, in the off-grid case, LCOH values are higher: the minimum value of LCOH by PSO, GA, and SA was 34.81 $/kg, while the highest was obtained from Gradient Descent with 42.85 $/kg. The main problems that the configuration faced in an off-grid setting were related to not being able to satisfy energy demand and increased curtailment rates. These findings evidence the economic advantages of on-grid systems and underline the necessity for additional measures in off-grid setups, such as energy storage, to reach higher performance and reliability.

The urgency of mitigating global warming and the growing threat of natural disasters demand swift and decisive action. Carbon Capture and Utilization (CCU) technologies have emerged as a solution to this challenge, capturing and converting carbon dioxide (CO2) into products, rather than allowing it to be released into the atmosphere. We explore public perception and acceptance of CCU-based products, with a focus on jet fuel as a case study. Using conjoint analysis within an online survey (N = 1204), we evaluated how contextual factors—transport options, energy sources, and production settings—affect consumer preferences. Participants rated both the acceptability of CO2-based jet fuel and the infrastructure required for its local and general production. The results suggest that preferences for the production conditions of CCU plants were driven more by energy supply and transport than by the type of plant manufacturing the final product in both local and general contexts. The acceptance of CCU plants and the production of CO2-based jet fuel in both contexts were the strongest predictors of overall acceptance. However, the final CCU product itself, regardless of context, was the least influential factor in shaping public perception. This study provides insights into public perceptions of the production of CO2-based jet fuel and identifies key factors influencing local and general acceptance. Our findings contribute to a deeper understanding of the societal dimensions of CCU adoption and complement efforts in technology development and regulatory frameworks necessary for technology integration.

Lignocellulosic biomass derived from food waste, microalgae, and agroresidues is key in the circular bioeconomy, promoting eco-friendly bioethanol production while addressing waste management challenges. This paper aimed to comprehensively review the role of amylases secreted from different strains in bioethanol production. The sources and optimizing factors critical for effective starch breakdown are discussed. Amylase, derived from various organisms, constitutes an essential enzyme and facilitates starch hydrolysis into fermentable sugars like glucose, a key step in bioethanol production. However, its activity depends on factors such as pH, temperature, incubation time, and the substrates used, necessitating optimization for efficient starch degradation. Moreover, the review also explores strategies to engineer amylase-producing strains with enhanced amylase production capabilities using an advanced clustered regularly interspaced short palindromic repeat (CRISPR/Cas9)-based gene editing technology. Further research is crucial to identify novel amylase-producing strains from different environments, including from extremophiles, characterize their enzymes, and leverage tools like CRISPR/Cas9-mediated genome editing in microorganisms, and leverage these advancements to ensure sustainable bioethanol production.
从食物垃圾、微藻和农业残留物中提取的木质纤维素生物质是循环生物经济的关键，可以促进生态友好的生物乙醇生产，同时解决废物管理方面的挑战。本文旨在全面综述不同菌株分泌的淀粉酶在生物乙醇生产中的作用。讨论了淀粉有效分解的来源和关键优化因素。淀粉酶来源于多种生物体，是一种必需的酶，能促进淀粉水解成葡萄糖等可发酵糖，这是生物乙醇生产的关键步骤。然而，其活性取决于pH、温度、孵育时间和所使用的底物等因素，因此需要对淀粉的有效降解进行优化。此外，该综述还探讨了利用基于CRISPR/Cas9的先进簇状规则间隔短回文重复（clustered regularly interspaced short palindromic repeat，简称Cas9）的基因编辑技术，设计具有增强淀粉酶生产能力的淀粉酶生产菌株的策略。进一步的研究对于鉴定来自不同环境的新型淀粉酶产生菌株至关重要，包括来自极端微生物，表征它们的酶，利用微生物中CRISPR/ cas9介导的基因组编辑等工具，并利用这些进步来确保可持续的生物乙醇生产。

In this study, the macroscopic properties of kerosene-H2 blended flames are investigated in a multi-phase, multi-fuel combustor, focusing on the effects of increasing H2 blending fractions. The non-reacting flow field of the swirl-stabilized combustor is characterized using PIV, and macro-structures in the flow and spray-swirl interactions are analyzed. Kerosene atomizers are tested to estimate variations in spray quality across different fuel blends. The changes in the optical properties of the flames are recorded using broadband chemiluminescence imaging while the changes in the acoustic emissions are recorded using a microphone. Results show that H2 addition significantly alters the flame topology, transitioning from a lobed flame for pure kerosene to a single contiguous swirling flame for blended or pure H2 cases. The flame luminosity decreases, with the emission color shifting from bright yellow (pure kerosene case) to dull yellow (multi-fuel cases) to a red-blue hue (pure H2 case). These changes are attributed to variations in fuel distribution, heat release patterns, combustion mode, flame speed, and soot formation tendencies. The acoustic analysis reveals that a strong tonal behavior is observed under pure fuel conditions (prominent peaks at higher harmonics of 150 Hz) while broadband characteristics are exhibited under blended fuel conditions. The overall acoustic emissions in multi-fuel cases are reduced by ∼80 % compared to pure H2 and ∼55 % compared to pure kerosene. This study highlights the effects of high levels of H2 blending on flame dynamics and acoustic behavior in a multi-phase, multi-fuel combustor, offering valuable insights for the development of fuel-agnostic combustion systems.

Background
This study develops a novel water-based fracturing fluid to address challenges of high water consumption, poor thermal stability, and inadequate proppant transport in conventional hydraulic fracturing fluids. Current fluids face limitations due to thermal degradation and environmental impact. To optimize performance, experimental analyses were conducted using water as the base fluid, with added gas condensate and various additives. Key assessments included viscosity measurements, stability tests across temperature ranges, and proppant fall rate evaluations.
Methods
The optimized formulation features a linear fluid with 45 cp viscosity and a crosslinked fluid enhanced to 135 cp through boric acid and a cross-linker. The addition of triethanolamine (TEA) further stabilized the fluid, reducing viscosity loss at higher temperatures. Comparative tests showed a 134 % viscosity increase in the crosslinked fluid, boosting proppant transport, while TEA addition decreased the proppant fall rate by 6.8 %.
Findings
Results confirm that the new fluid meets API standards, offering improved thermal stability and proppant transport efficiency, addressing key environmental concerns. This formulation represents a promising alternative for more effective and sustainable hydraulic fracturing.

This study evaluates the environmental impacts of using Refuse-Derived Fuel (RDF) as an alternative fuel in the cement industry during natural gas shortages in Tehran, Iran. Given the increasing municipal solid waste production and the cement industry's significant carbon emissions, this research takes an innovative approach to assess RDF's potential to mitigate these issues through a life cycle approach. The analysis employs OpenLCA software to compare the environmental effects of RDF against traditional fossil fuels fuel oil and coal during colder months when natural gas is scarce. The study examines two RDF compositions, including organic waste and one excluding it, to determine their impacts on sustainability and fuel efficiency. Key findings indicate that RDF, mainly when produced with organic waste, offers substantial reductions in global warming potential (GWP) and other environmental impacts compared to conventional fuels. Specifically, the results demonstrate that RDF can significantly lower CO₂ emissions associated with cement production, positioning it as a viable option for enhancing energy sustainability within the industry.

The analysis employs OpenLCA software to compare the environmental effects of RDF against traditional fossil fuels fuel oil and coal during colder months when natural gas is scarce. The study examines two RDF compositions, including organic waste and one excluding it, to determine their impacts on sustainability and fuel efficiency. Key findings indicate that RDF, mainly when produced with organic waste, offers substantial reductions in global warming potential (GWP) and other environmental impacts compared to conventional fuels. Specifically, the results demonstrate that RDF can significantly lower CO₂ emissions associated with cement production, positioning it as a viable option for enhancing energy sustainability within the industry.

The heat capacity of the flue gas is a basic property of a combustion process since it establishes the link between the energy balance and the combustion temperature. The dependencies of the average specific heat capacity on composition and temperature are thus of significance in interpreting differences in the achievable combustion temperature of different fuels. In this contribution, these dependencies are discussed and evaluated to provide simple correlations for use in practice. The correlations are applicable over the wide temperature range of 25…1600°C, while deviations at higher temperature are mainly due to dissociation of polyatomic gases. The provided correlations are also applicable if an oxygen carrier other than air is used, so that they are useful for a wide range of practical applications. This study also shows that the specific heat capacities of flue gases from different fuels are very similar, which is another reason – besides their similar "heat of oxidation" – why the adiabatic flame temperatures of different fuels are within a narrow range.
