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.

交通行业不断增加的排放对现代社会构成了重大挑战，对气候变化产生了广泛影响。减少这些排放的一个有希望的方法是开发以二氧化碳为基础的替代燃料，这种燃料可以通过捕获和再利用二氧化碳排放来减少对汽油和柴油等化石燃料的依赖。虽然已对这些燃料的技术可行性进行了广泛的研究，但关于如何传达替代燃料的信息的消费者偏好的研究有限。了解传播偏好对于设计有效的传播策略至关重要，因为它们决定了个人如何处理信息，形成态度，并最终决定是否采用可持续技术，从而促进公众接受和采用。为了解决这一差距，我们进行了一项在线调查研究（N = 215），以探讨外行人对替代燃料的看法，重点关注他们的信息需求和沟通偏好。结果显示，两种不同的消费者群体对内容、渠道、可信赖的信息和沟通来源有着不同的期望。一组更喜欢来自机构的详细的、基于科学的信息，而另一组更喜欢来自行业或媒体的可访问的、以实践为导向的内容。这些发现强调需要量身定制的沟通策略，以反映不同的信任动态和信息偏好。它们为决策者和行业参与者提供了实用指导，旨在提高公众对二氧化碳替代燃料的参与度和接受度。

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.

目前的研究工作涉及到一个混合可再生能源系统的优化，该系统将废物发电（WTE）和光伏（PV）技术结合起来，在并网和离网两种运行模式下通过水电解制氢。额定容量为3mw的WTE电厂与容量从0.5到3mw的光伏阵列相结合。采用粒子群优化（PSO）、遗传算法（GA）、模拟退火（SA）、梯度下降（Gradient Descent）和牛顿法（Newton’s Method）算法，在保证能源可靠性的同时最小化氢的平准化成本（LCOH）。在并网场景下，PSO、GA和SA的最低LCOH约为-399.215美元/kg，这表明在电网进出口的帮助下，成本效益显著。离网条件下，PSO、GA和SA的LCOH最小值为34.81 $/kg，梯度下降法的LCOH最大值为42.85 $/kg。在离网环境下，该配置面临的主要问题与无法满足能源需求和弃风率增加有关。这些发现证明了并网系统的经济优势，并强调了在离网装置中采取额外措施（如储能）以达到更高性能和可靠性的必要性。

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.

缓解全球变暖和日益严重的自然灾害威胁的紧迫性要求采取迅速和果断的行动。碳捕集与利用（CCU）技术已经成为应对这一挑战的解决方案，它捕获并将二氧化碳（CO2）转化为产品，而不是将其释放到大气中。我们探讨了公众对基于ccu的产品的看法和接受程度，并以航空燃料为例进行了重点研究。利用在线调查（N = 1204）中的联合分析，我们评估了环境因素——交通选择、能源和生产环境——如何影响消费者偏好。与会者对基于二氧化碳的航空燃料的可接受性以及当地和一般生产所需的基础设施进行了评级。结果表明，在当地和一般情况下，对CCU工厂生产条件的偏好更多地取决于能源供应和运输，而不是制造最终产品的工厂类型。在这两种情况下，CCU工厂的接受度和二氧化碳基喷气燃料的生产是总体接受度的最强预测指标。然而，最终的CCU产品本身，无论背景如何，是塑造公众认知的最不具影响力的因素。这项研究提供了公众对二氧化碳基航空燃料生产的看法，并确定了影响当地和普遍接受程度的关键因素。我们的研究结果有助于更深入地了解CCU采用的社会层面，并补充了技术开发和技术整合所需的监管框架方面的努力。

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.

在多相、多燃料燃烧室中，研究了煤油-H2混合火焰的宏观特性，重点研究了增加H2混合分数的影响。利用PIV对旋流稳定燃烧室的非反应流场进行了表征，分析了流动和喷雾-旋流相互作用中的宏观结构。对煤油雾化器进行了测试，以估计不同燃料混合物中喷雾质量的变化。利用宽带化学发光成像技术记录火焰光学特性的变化，同时利用传声器记录声发射的变化。结果表明，H2的加入显著地改变了火焰的拓扑结构，从纯煤油的分叶火焰转变为混合或纯H2情况下的单个连续旋转火焰。火焰亮度降低，发射颜色从亮黄色（纯煤油情况）到暗黄色（多燃料情况）再到红蓝色色调（纯H2情况）。这些变化归因于燃料分布、热释放模式、燃烧模式、火焰速度和烟灰形成趋势的变化。声学分析表明，在纯燃料条件下观察到强烈的音调行为（在150 Hz的高谐波处显著峰值），而在混合燃料条件下表现出宽带特性。与纯氢气相比，多燃料情况下的总声发射减少了~ 80%，与纯煤油相比减少了~ 55%。这项研究强调了高水平的H2混合对多相、多燃料燃烧器中火焰动力学和声学行为的影响，为开发与燃料无关的燃烧系统提供了有价值的见解。

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.

本研究开发了一种新型水基压裂液，以解决传统水力压裂液耗水量大、热稳定性差、支撑剂输送不足等问题。由于热降解和环境影响，目前的流体面临限制。为了优化性能，以水为基液，加入凝析油和各种添加剂进行了实验分析。关键评估包括粘度测量、温度范围内的稳定性测试和支撑剂下降速率评估。方法优化后的配方为45 cp的线性流体，通过硼酸和交联剂将交联流体的粘度提高到135 cp。添加三乙醇胺（TEA）进一步稳定了流体，降低了高温下的粘度损失。对比测试表明，交联液的粘度增加了134%，促进了支撑剂的运输，而TEA的加入使支撑剂的下降率降低了6.8%。研究结果证实，新流体符合API标准，具有更好的热稳定性和支撑剂输送效率，解决了关键的环境问题。该配方代表了一种更有效、更可持续的水力压裂替代方案。

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 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.

烟气的热容量是燃烧过程的一个基本性质，因为它建立了能量平衡和燃烧温度之间的联系。因此，平均比热容对成分和温度的依赖性在解释不同燃料可达到的燃烧温度的差异方面具有重要意义。在本文中，对这些依赖关系进行了讨论和评估，以提供在实践中使用的简单相关性。相关性适用于25 ~ 1600°C的宽温度范围，而在较高温度下的偏差主要是由于多原子气体的解离。所提供的相关性也适用于使用除空气以外的氧载体，因此它们在广泛的实际应用中是有用的。本研究还表明，不同燃料的烟气比热容非常相似，这是不同燃料的绝热火焰温度在一个狭窄范围内的另一个原因——除了它们相似的“氧化热”。

Africa has a pressing need for biofuel policies due to several interconnected challenges encompassing vulnerability to price fluctuations, rural development, waste and land use management, and the need for value-added agricultural goods. State biofuel policies contribute to the ongoing global discourse on climate change, green and circular economy, and sustainability. Unfortunately, the resource curse seems to have befallen the Ghanaian economy as the nation still imports petroleum products after discovering enormous oil reserves. This article reviews Ghana's current biomass potential drawing lessons from failed projects and initiatives of top biofuel nations to effectively implement Ghana's latest biofuel policy. A significant portion of land in Ghana remains unused, yet utilizing less than 3 % of this land would be sufficient to meet the B10/E10 biofuel target using cassava as the feedstock. A closer examination of successful biofuel initiatives in Brazil and the United States highlights common factors contributing to their achievements. These include ambitious blending mandates, substantial investments in infrastructure, technology, and research, active stakeholder participation, and the provision of fiscal incentives. While Ghana's Renewable Energy Master Plan incorporates some of these components, its current targets lack sufficient ambition. Addressing these gaps in practice could place Ghana on a trajectory toward becoming one of the world's leading biofuel producers.

由于若干相互关联的挑战，包括易受价格波动影响、农村发展、废物和土地使用管理以及对增值农产品的需求，非洲迫切需要生物燃料政策。各国的生物燃料政策促进了当前关于气候变化、绿色和循环经济以及可持续性的全球讨论。不幸的是，虽然发现了巨大的石油储量，但加纳仍在进口石油产品，因此“资源诅咒”似乎已经降临到加纳经济身上。本文回顾了加纳目前的生物质潜力，从生物燃料大国的失败项目和倡议中吸取教训，以有效实施加纳最新的生物燃料政策。加纳有很大一部分土地未被利用，但利用不到3%的土地就足以满足以木薯为原料的B10/E10生物燃料的目标。对巴西和美国成功的生物燃料计划进行更仔细的考察，突出了促成它们取得成就的共同因素。这些措施包括雄心勃勃的混合指令，对基础设施、技术和研究的大量投资，利益相关者的积极参与，以及提供财政激励。虽然加纳的可再生能源总体规划包含了其中的一些组成部分，但其目前的目标缺乏足够的雄心。在实践中解决这些差距可以使加纳走上成为世界领先的生物燃料生产国之一的轨道。

Switchable hydrophilic solvents (SHS) and deep eutectic solvents (DES) are trending chemical agents used in enhanced oil recovery. In this study, the oil recovery performance of DES, synthesized from tetrabutylammonium bromide (TBAB) and polyethylene glycol 400 (PEG 400) in a 1:2 molar ratio, and the switchable solvent N,N-dimethylcyclohexylamine (DMCHA) was evaluated through a displacement test. Additionally, the interactions between the rock, solvents, and crude oil were investigated through interfacial tension (IFT) measurements using an Altension tensiometer. The trend in the experimental IFT results was compared to the interactions between DMCHA and oil, DMCHA and rock, DES and oil, and DES and rock using quantum mechanics calculations performed with the Spartan v20 molecular modeling tool. The findings revealed that the IFT between the solvents and oil decreased to 5.32 mN/m with DES and 2.64 mN/m with DMCHA. Furthermore, core flooding experiments showed an incremental recovery of 12.0 % of the original oil in place (OOIP) with DES and 10.0 % OOIP with DMCHA for standard Berea sandstone core samples. Similarly, flooding experiments using Niger-Delta sandstone samples achieved an additional 25.8 % OOIP with DES compared to 12.0 % OOIP with DMCHA. In conclusion, both DES and DMCHA demonstrated their potential for crude oil recovery. However, DES proved to be more promising for tertiary enhanced oil recovery applications.

可切换亲水溶剂（SHS）和深共晶溶剂（DES）是提高采收率的发展趋势。本研究以四丁基溴化铵（TBAB）和聚乙二醇400 （PEG 400）为原料，以1:2的摩尔比合成了DES的采油性能，并通过置换试验评价了可切换溶剂N，N-二甲基环己胺（DMCHA）。此外，通过Altension张力仪的界面张力（IFT）测量，研究了岩石、溶剂和原油之间的相互作用。利用Spartan v20分子建模工具进行量子力学计算，将实验IFT结果的趋势与DMCHA与油、DMCHA与岩石、DES与油以及DES与岩石之间的相互作用进行了比较。结果表明，溶剂与油之间的IFT在DES和DMCHA的作用下分别降至5.32 mN/m和2.64 mN/m。此外，岩心驱油实验表明，对于标准的Berea砂岩岩心样品，使用DES和DMCHA的原始产油量（OOIP）的增量采收率分别为12.0%和10.0%。同样，尼日尔三角洲砂岩样品的驱油实验中，DES的OOIP为25.8%，而DMCHA的OOIP为12.0%。综上所述，DES和DMCHA都显示了它们的原油采收率潜力。然而，事实证明，DES在提高三次采收率的应用中更有前景。
