This review manuscript delves into lignocellulosic biomass (LCB) as a sustainable energy source, addressing the global demand for renewable alternatives amidst increasing oil and gas consumption and solid waste production. LCB, consisting of lignin, cellulose, and hemicellulose, is versatile for biochemical and thermochemical conversions like anaerobic digestion, fermentation, gasification, and pyrolysis. Recent advancements have led to a 25 % increase in bioethanol yields through alkali pre-treatment and optimized fermentation, a 20 % enhancement in microbial delignification efficiency, and a 35 % improvement in enzyme efficiency via nanobiotechnology. These innovations enhance biofuel production sustainability and cost-effectiveness. Decentralized energy systems utilizing locally produced biomass can reduce transmission losses and greenhouse gas emissions by up to 30 %, fostering community energy independence. These developments significantly contribute to global sustainability and socio-economic development by converting waste into valuable energy, promoting environmental stewardship, and supporting economic resilience. Furthermore, this review also discusses innovative strategies to address technological, economic, and environmental challenges and highlights the role of decentralized solutions in promoting sustainable energy production.

Organic Rankine Cycle (ORC) is a power cycle for the exploitation of low-grade energy sources like solar irradiation, geothermal energy, waste heat streams, etc. Different ORC designs have been suggested in the literature aiming to enhance the system’s performance and maximize electricity production. The present review study aims to present and discuss in detail the use of partial evaporation and the dual-phase expansion in the ORC for maximizing the exploitation of the energy source. Usually, the waste heat sources are ideal candidates for the application of the studied idea, while also there are designs with solar thermal sources that use partial-evaporation designs. The working fluid selection, the optimal vapor quality in the expander inlet, the expander selection and other issues are presented and discussed in this work. The analysis of the literature reported results indicates that the system efficiency ranges from 3% up to 16%, while the respective thermodynamic efficiency takes a bit higher value which reaches up to 17.5%. The conclusions of the present review can be exploited for the further development of the ORC with partial evaporation aiming at the sustainability of this technology.

Logistics facilities, while critical to industrial systems, significantly contribute to greenhouse gas emissions, necessitating improved operations, energy use, and renewable energy integration. The use of distributed renewable energy sources, with their intermittent and unpredictable generation, disrupts energy balance and leads to curtailment issues. This places a significant load on the electrical grid, increasing emissions and environmental problems, hindering the effective use of renewable energy. To address these challenges, modifications can be made to existing warehouses to increase their self-consumption. Empirical studies assessing the impact of such modifications, particularly in the logistics field, are lacking. This work contributes to the ongoing research by proposing a simulation-based approach that evaluates multiple scenarios for a real-world logistics facility to enhance the self-consumption ratio. This analysis is based on a conceptual framework providing a roadmap towards sustainable warehousing practices. The study simulates and presents multiple scenarios, including the base case, electrification of the heating system, and an opportunity charging strategy for MHE, aiming to enhance self-consumption, while examining environmental and economic performances, followed by a sensitivity analysis. Findings demonstrate a 25% increase in self-consumption and significant energy consumption reduction (-110 MWh/year) and CO2e emissions (-67.8 tons CO2e/year) for the final proposed scenario.

物流设施对工业系统至关重要，但也是温室气体排放的主要来源，因此必须改善运营、能源利用和可再生能源整合。分布式可再生能源的使用具有间歇性和不可预测性，会破坏能源平衡，导致能源削减问题。这给电网带来了巨大的负荷，增加了排放和环境问题，阻碍了可再生能源的有效利用。为了应对这些挑战，可以对现有仓库进行改造，以增加其自我消耗。目前还缺乏评估此类改造影响的实证研究，尤其是在物流领域。本研究提出了一种基于模拟的方法，对现实世界中物流设施的多种方案进行评估，以提高自消耗率，从而为正在进行的研究做出贡献。该分析基于一个概念框架，为可持续仓储实践提供了路线图。该研究模拟并提出了多种方案，包括基本方案、供热系统电气化方案和 MHE 机会充电策略，旨在提高自用率，同时考察环境和经济性能，并随后进行了敏感性分析。研究结果表明，在最终提出的方案中，自我消费增加了 25%，能源消耗大幅减少（-110 兆瓦时/年），二氧化碳排放量大幅减少（-67.8 吨二氧化碳/年）。

Energy is crucial for technological, scientific, and societal development. Since industrialization, the quest for cheap and abundant energy has led to reliance on fossil fuels across key societal sectors. However, this unrestrained use of fossil fuels has driven climate change, particularly through significant greenhouse gas (GHG) emissions. The early 21st century has seen heightened environmental awareness and efforts to mitigate environmental damage, leading to a search for alternative energy sources. Hydrogen has emerged as a promising energy source due to its potential for low GHG emissions. This paper presents a literature review on hydrogen technologies and economics, outlining the processes for developing an efficient and safe hydrogen infrastructure. The review encompasses all stages of the hydrogen pathway: production, storage, transportation, and end use. Based on this review, two SWOT analyses are conducted: one for the global context and one specific to Brazil, incorporating the studies on the review and Brazil-specific research. These analyses have enabled the development of a potential hydrogen economy in Brazil, based on green hydrogen, for which the country has significant generation potential. However, it also highlights the challenges to be addressed, such as hydrogen storage, which poses a threat both globally and within Brazil. Additionally, the transportation of hydrogen to major consumption centers could be challenging, as production may occur in areas distant from large urban centers due to the country’s vast territorial expanse.

能源对于技术、科学和社会发展至关重要。自工业化以来，对廉价和丰富能源的追求导致社会各主要部门对化石燃料的依赖。然而，对化石燃料的无节制使用导致了气候变化，特别是温室气体的大量排放。21 世纪初，人们的环保意识不断提高，并努力减轻对环境的破坏，从而开始寻找替代能源。由于氢具有低温室气体排放的潜力，它已成为一种前景广阔的能源。本文对氢能技术和经济学进行了文献综述，概述了开发高效、安全的氢能基础设施的过程。文献综述涵盖了氢气利用途径的所有阶段：生产、储存、运输和最终使用。在该综述的基础上，进行了两项 SWOT 分析：一项是全球范围的 SWOT 分析，另一项是针对巴西的 SWOT 分析，其中纳入了有关综述的研究和针对巴西的研究。这些分析有助于在巴西发展以绿色氢为基础的潜在氢经济，巴西在这方面具有巨大的潜力。不过，报告也强调了需要应对的挑战，如氢储存问题，这对全球和巴西国内都构成了威胁。此外，将氢气运输到主要消费中心可能具有挑战性，因为巴西幅员辽阔，生产氢气的地区可能远离大型城市中心。

Hydrothermal carbonization (HTC) can efficiently utilize human faeces and urine as the feedstock and convert them to carbon and nutrient-rich hydrochar and process water. This study investigated the influence of solid content (5, 10, 15, 20, 25, and 30 % of faecal matter, respectively) on the produced hydrochar and process water characteristics. The HTC of human faeces with urine as the reaction medium, at 200 °C for 2 h, resulted in a hydrochar yield of approximately 69.2 to 76.1 wt%, with a heating value ranging from 26.6 to 28.9 MJ/kg. The solubilization of carbon and nutrients in process water resulted in a total organic carbon (TOC) increase from 1.7 g/L in urine to 38.9 g/L in process water following the application of HTC. Furthermore, the morphology and weight % of elements analysed by SEM-EDS demonstrated that struvite was formed from produced process water at an optimum solid content of 10 %. Overall, the hydrochar and process water are rich in nutrients and energy, rendering them suitable for resource recovery.

To achieve the transition towards net-zero carbon economy and transport, reducing the emissions of greenhouse gases and improving the quality of life in the coastal areas, decarbonization of various naval fleets will be essential. In this research, gradual decarbonization, using different hybrid, electric and hydrogen technologies for decarbonization of fleets engaged in activities such as fishery, passenger transport and transport of goods near the coast is investigated and modelled in connection to the power systems’ configuration. The energy system analysis and simulations are carried out in H2RES, a linear energy systems’ configuration optimization software. It considers capacity expansion, decommission and unit commitment in the sectors of power generation, heating, industry, and transport. In this particular case, transport sector module is expanded to provide realistic modelling of different naval fleets’ energy consumption, on the example of fishery fleet. This is performed through the inclusion of learning curves of different technologies that are expected in the naval transport, to replace the old internal combustion engine power drives and the demand curves that characterize the fishery fleet. Results include the changes in the variable renewable energy integration in the sectors of energy demand, general and bottom-up assessments of economic benefits and emissions reduction. Results demonstrate that the presented approach can offer better insights into the changes that are needed in an energy system based on renewable energy sources, in case of detailed modelling of the energy needs emphasized by a fishery fleet and different dynamics of its decarbonization. Through internalization of all costs, the resulting system also achieves better economic results as a whole and from the bottom-up perspective.

为了实现向净零碳经济和运输的过渡，减少温室气体排放，提高沿海地区的生活质量，各种舰队的脱碳至关重要。在这项研究中，利用不同的混合动力、电动和氢气技术对从事渔业、客运和近海货物运输等活动的船队进行逐步脱碳研究，并结合动力系统配置进行建模。能源系统分析和模拟在线性能源系统配置优化软件 H2RES 中进行。它考虑了发电、供热、工业和运输部门的产能扩张、退役和单位承诺。在本案例中，以渔业船队为例，对运输部门模块进行了扩展，以提供不同海军船队能源消耗的真实模型。该模块通过纳入不同技术的学习曲线来实现，预计这些技术将用于海军运输，以取代旧的内燃机动力驱动装置，并纳入渔业船队的需求曲线。结果包括能源需求部门中可变可再生能源集成的变化、经济效益和减排的一般评估和自下而上的评估。结果表明，在对渔业船队强调的能源需求和不同的去碳化动态进行详细建模的情况下，所提出的方法可以更好地洞察基于可再生能源的能源系统所需的变化。通过将所有成本内部化，由此产生的系统还能从整体上和自下而上的角度取得更好的经济效益。

The global waste crisis is exacerbated by the massive daily consumption and disposal of millions of cigarettes. An effective solution to address this issue involves repurposing cigarette butts (CBs), offering a promising avenue for waste management. This research focuses on transforming CBs into environmentally sustainable building materials. A comprehensive analysis of the most common types of CBs was conducted to assess their different thermal and acoustic properties. Subsequently, these CBs were integrated at 2.5 wt% in both a gypsum and cement mixture to produce panels for building applications. In addition, the feasibility of introducing a significantly higher concentration of CBs into these mixtures to produce mineralized samples was explored, achieving a CBs: gypsum/cement: water ratio of 1:2:3. All the panels analyzed showed superior thermal and acoustic characteristics compared to traditional ones, demonstrating the potential of this innovative approach. The introduction of CBs enhanced panel thermal properties and acoustic absorption coefficients. Incorporating recycled CBs in building material production promotes the creation of efficient, sustainable products while extending the lifespan of discarded waste. Life Cycle Assessment of a gypsum panel with CBs analyzed emissions, significantly contributing to waste management by reducing emissions and minimizing harmful substance release into the environment.

每天数以百万计的香烟被大量消耗和丢弃，加剧了全球废物危机。解决这一问题的有效办法是将烟头（CBs）再利用，这为废物管理提供了一条前景广阔的途径。这项研究的重点是将烟头转化为环境可持续建筑材料。研究人员对最常见类型的烟头进行了全面分析，以评估其不同的热学和声学特性。随后，在石膏和水泥混合物中以 2.5 wt% 的比例混合这些 CB，以生产建筑用板材。此外，还探讨了在这些混合物中引入更高浓度的 CBs 以生产矿化样品的可行性，使 CBs：石膏/水泥：水的比例达到 1:2:3。与传统板材相比，所有被分析的板材都显示出更优越的热学和声学特性，证明了这种创新方法的潜力。CBs 的引入增强了板材的热性能和吸声系数。在建筑材料生产中采用回收的 CB 可促进创造高效、可持续的产品，同时延长废弃物的使用寿命。使用 CBs 的石膏板的生命周期评估分析了排放情况，通过减少排放和最大限度地减少向环境中释放有害物质，极大地促进了废物管理。

The present study comprehensively examines the application of hydro, wave, tidal, undersea current and geothermal energy sources of Canada for green hydrogen fuel production. The estimated potential capacity of each province is derived from official data and acceptable assumptions and is subject to discussion and evaluation in the context of a viable hydrogen economy. According to the findings, the potential for green hydrogen generation in Canada is projected to be 48.86 megatons. The economic value of the produced green hydrogen results in an equivalent of 21.30 billion US$. The top three provinces with the highest green hydrogen production potential using hydro resources, including hydro, wave, tidal, undersea current and geothermal, are Alberta, Quebec, and British Columbia with 26.13 Mt, 7.34 Mt, and 4.39 Mt, respectively. Quebec is ranked first by only considering the marine sources, including 4.14 Mt with hydro, 1.46 Mt with wave, 0.27 Mt underwater current, and 1.45 Mt with tidal, respectively. Alberta is listed as the province with the highest capacity for hydrogen production from geothermal energy, amounting up to 26.09 Mt. The primary objective is to provide comprehensive hydrogen maps for each province in Canada, which will be based on the identified renewable energy potential and the utilization of electrolysers. This may further be examined within the framework of the prevailing policies implemented by local communities and officials in order to develop a sustainable energy plan for the nation.

The burning of carbon rich fuels is associated to be the primary cause of developing large quantity of greenhouse gases which alters the earth’s ecosystem, thereby causing problems in human health and environment. This study investigates the use of various lignocellulose biomass sources—Sugarcane Bagasse, Rice Husk, Wheat Straw, Moringa, and Vetiver—in conjunction with different nanoparticles to create combinations aimed at reducing volatile matter to be used in co-pyrolysis operation in a thermal powerplant. The chosen outcome parameters for clustering these nanoparticles include energy yield, combustion efficiency, ash generation, and SO₂ emission. An Adaptive Neuro Fuzzy Interface System (ANFIS) model is employed to identify trends and relationships between biomass-nanoparticle combinations and the output parameters. K-means cluster analysis is used to categorize the combinations into best, worst, and average clusters. The ANFIS algorithm reveals that the relationship is Trapezoidal with the smallest combined error rates. Among the tested combinations, Moringa coupled with silver nanoparticles emerged as the optimal biomass-nanoparticle pair, exhibiting the smallest centroidal distance of 0.14 from the best cluster centroid. Moringa and Silver nanoparticles achieved significant cost reduction and emissions reduction, with outputs showing an energy yield of 19.8 Mg/kg, combustion efficiency of 82.4 %, ash generation of 2.7 %, and SO₂ emission of 0.2 g/kg.

燃烧富碳燃料是产生大量温室气体的主要原因，温室气体改变了地球的生态系统，从而给人类健康和环境带来问题。本研究调查了各种木质纤维素生物质来源（甘蔗渣、稻壳、小麦秸秆、辣木和香根草）与不同纳米粒子的结合使用情况，以创造出旨在减少挥发性物质的组合，用于热电厂的共热解操作。对这些纳米粒子进行聚类所选择的结果参数包括能量产量、燃烧效率、灰分产生量和二氧化硫排放量。采用自适应神经模糊接口系统（ANFIS）模型来确定生物质-纳米颗粒组合与输出参数之间的趋势和关系。K-means 聚类分析用于将组合分为最佳、最差和平均聚类。ANFIS 算法显示，两者之间的关系为梯形，综合误差率最小。在测试的组合中，辣木与纳米银颗粒是最佳的生物质-纳米颗粒组合，与最佳聚类中心点的中心距最小，仅为 0.14。辣木和银纳米粒子显著降低了成本并减少了排放，结果显示能量产量为 19.8 兆克/千克，燃烧效率为 82.4%，灰分产生率为 2.7%，二氧化硫排放量为 0.2 克/千克。
