Ammonia is a promising zero-carbon fuel with features that include a high hydrogen density and ease of storing and transporting. Solid oxide fuel cells (SOFCs) are efficient and clean energy conversion devices. Direct ammonia fuel SOFCs (DA-SOFCs) possess evident cost effectiveness and practicality. The efficient and compact DA-SOFCs is ideal for electric power and transportation applications. At medium-high temperatures (700–1000 °C), the use of ammonia in traditional SOFCs can achieve performance close to hydrogen. However, high temperatures are detrimental to the long - term stability and commercialization of the cell. Thus, low temperature DA-SOFCs (<600 °C) are attractive for low cost and commercialization. But low ammonia decomposition rate and high polarization at low temperatures hindering their progress. Our objective is to present the progress on low temperature SOFCs and ammonia decomposition catalysts over the two decades, including advanced DA-SOFCs performance, characteristics of low temperature induced performance loss, high-performance cell structures, and ammonia decomposition catalysts. The implementation strategies of low operating temperature DA-SOFCs are introduced, including low polarization cell structures, such as semiconductor ion membrane fuel cells (SIMFCs) and hydrogen-permeable metal supported thin film fuel cells (HMFCs), are applied to enhance the low temperature performance. High-entropy alloys, alkaline promoters and hydrogen-permeable metal supports are utilized to increase the ammonia decomposition rate. This review is a state - of - the - art survey of DA-SOFCs, covering performance, materials, techniques, and basic principles, focusing on the implementation and prospects of low temperature DA-SOFCs.

An effective energy management system in a microgrid is of paramount importance, optimizing local energy utilization for diverse consumer needs. Prevalent strategies often rely on offline day-ahead or two-stage methods, assuming stable microgrid configurations or precise forecasts—a challenge in practical operations. A real-time energy management system approach struggles to achieve global optimal solutions, though inherently providing robustness against forecast uncertainties. A recent and promising approach is applying the Lyapunov optimization method, known for online optimization, to address challenges in real-time microgrid energy management systems. This paper provides a comprehensive exploration of Lyapunov-based real-time energy management systems in microgrids. We begin by elucidating the integration of the Lyapunov method into microgrid energy management. Categorizing pertinent research papers systematically, we differentiate parameters such as microgrid components with respect to real-time energy management systems, objective functions, and designs of the Lyapunov algorithm, covering establishment of virtual queues, drift-plus-penalty, and the control parameter roles of the algorithm. Integral to our investigation is a thorough assessment of the efficacy of the Lyapunov method in real-time microgrid energy management. The analysis highlights the efficacy of Lyapunov optimization in microgrid energy management system operation and underscores it as a solution to real-time energy management system challenges in microgrids, establishing its merits and applicability in scholarly and practical contexts.

Energy recovery devices (ERDs), are increasingly adopted across various industries due to escalating global concerns regarding finite energy resources and associated environmental impacts. Pressure exchangers (PX), a common ERD, is an integral part of key industries like desalination and is increasingly prevalent in other energy-intensive industries like refrigeration. PXs play pivotal roles in reducing energy consumption by harnessing waste hydraulic energy within working cycles. The efficiency and recoverable energy in PXs are significantly influenced by internal leakages. While leakage is well-understood in individual bearings and mechanical seals, leakage within PXs remains a complex phenomenon due to the interdependency of multiple axial and radial leakage flows. Aligned with UN SDG 7 (Affordable and Clean Energy), PXs enhance the efficiency of critical technologies, resulting in lower energy consumption, improved system performance, and a reduction in GHG emissions. This reduction in emissions also plays a key role in supporting SDG 13 (Climate Action). Therefore, optimizing PX efficiency and minimizing losses are essential to maximizing their impact. This article provides a comprehensive modeling approach to analyze leakages and properties variation within bearings in PXs. Furthermore, a global optimization search methodology was developed to capture the interconnected nature of leakages and properties at the leakages intersection zones. Models for both radial and annular leakages within PXs were developed to analyze flow rates and variation of properties within bearings. These models avoid idealized assumptions and are based on real fluids. Models’ predictions for properties variation within bearings and pressures within leakage intersection zones were found to be in a good agreement with CFD and experimental validation.

The integration of power electronics-based energy storage systems (PEESs) into power systems introduces potential instabilities. This study reviews efforts in dynamic analysis of both AC and DC power systems integrated with PEESs, covering dynamic modeling, analysis methods, and potential instability risks. Major conclusions are drawn as: 1) Simplified models of PEESs have been widely used for dynamic analysis of power systems. However, it may cause "error aggregation" as the scale of PEESs increases, leading to mistakes in results, which induces significant concerns. 2) Traditional stability mechanism analysis methods remain effective for single grid-connected PEES and large-scale PEESs with parallel and series connections. However, they are inadequate for PEESs with distributed connections. To fill in this gap, an idea of mechanism analysis based on "dynamic reconstruction" is proposed. 3) Potential instability risks caused by PEESs integration may differ from those caused by renewable energy integration due to differences in functional controls and bidirectional power flow. However, comprehensive investigations in this regard are lacking and require significant attention. To ensure the stable operation of power systems with increasing integration of PEESs, significant challenges are summarized in the end, providing inspirations for future studies.

The main objective of this article is to explore the utilization of sorghum as a potential substrate to produce valuable enzymes using Aspergillus strains. It focuses on two key aspects: (i) the environmental and economic sustainability of enzyme production from sorghum ii. enhancing enzymes and biofuel production through process and host cell optimization. A comparative study is conducted among sorghum, wheat, and corn to understand the current state of knowledge and research gap on large-scale enzyme production. Sorghum is an adaptable crop with all types of environments and is overall more sustainable than wheat and corn. With its rich composition of starch (60%-75%), lignin (11%-25%), hemicellulose (18%-25%), and cellulose (25%-45%), sorghum represents itself an excellent candidate for the enzyme, and also first and second-generation biofuel production. The advantages and associated challenges of the Aspergillus strains are then discussed for enzyme production. It highlights the development of an integrated process for enzyme and bioethanol production at a low cost without relying on external carbon and nitrogen sources through an eco-friendly and economically viable approach.

Extreme weather events caused by climate change can affect the energy sector in different ways. For example, extreme heat, cold spells, strong winds, or flooding may lead to increased energy demand and consumption, reduced energy production, or cause infrastructure failures and outages. Underserved communities are among those most impacted by power outages resulting from extreme weather events due to lower infrastructure investment in the areas where they live. These phenomena encompass a variety of social and technical challenges, for which we propose a new, transdisciplinary framework to explore solutions for providing clean, affordable, and resilient energy systems to vulnerable and at-risk communities. The authors consider a new approach using perspectives from engineering, hazards science, and policy studies to identify and develop solutions for the expansion of the use of solar energy production coupled with increased storage capacities in places where power outages and social vulnerability intersect.

This study presents a geodata-based analysis of agrivoltaic potential and site selection in Germany, addressing the country's photovoltaic expansion targets to achieve climate neutrality by 2045. By integrating Geographic Information Systems with the Analytical Hierarchy Process, the study quantifies available agricultural areas and identifies optimal sites. Notably, it is the first to apply a Multi-Criteria Decision-Making approach considering all agricultural classes. Two criteria catalogs were developed: the first for potential analysis, incorporating geographical factors and legal and regulatory requirements, categorized into hard and soft restrictions; the second for site selection, considering political-economic and agro-economic suitability criteria, with weightings assigned by experts. A Land Suitability Index was calculated to classify areas into five suitability classes, from most suitable to least suitable. The study introduced two new potential levels, regulatory and synergy potential. This research showed a regulatory potential of 7900 GWp (Scenario 1) and 5600 GWp (Scenario 2) and a synergy potential of 136 GWp (Scenario 1) and 98 GWp (Scenario 2). The most suitable areas, in terms of economic feasibility, indicate an installable capacity of 800 GWp (Scenario 1) and 500 GWp (Scenario 2), approximately 3.5- and 2.5-times Germany's photovoltaic expansion targets for 2030. The sensitivity analysis indicated that the most suitable areas varying between 8.4 % and 12.8 %, suggesting the robustness of the results. This study contributes to the Sustainable Development Goal 7 and 13, providing a robust data foundation for policymakers and stakeholders to promote the expansion of renewable energy and contribute to achieving climate goals.

Despite a surge in Foreign Direct Investment (FDI) in Mexico, like nearshoring, the slow growth in international investment in renewables challenges the country's progress in achieving Sustainable Development Goals (SDGs) related to clean energy. To the best of current knowledge, this research is one of the first to explore the integration of renewable energy (Green/Blue/Turquoise Hydrogen, Solar, and Wind plants) in Mexico, emphasizing a diverse portfolio of projects aligned with SDGs and Industry 5.0. While previous works have focused on the nexus between energy, Industry 4.0, and sustainability, the present study advances this discourse by incorporating Industry 5.0 principles and a comprehensive methodological approach. Through a comprehensive methodology involving Value-Focused Thinking (VFT), fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL), and multi-objective mathematical programming, the study identifies key criteria encompassing social, economic, environmental, and technological dimensions. The resulting criteria form a robust framework for evaluating project sustainability. The fuzzy DEMATEL analysis reveals intricate interrelations among criteria, emphasizing the need for balanced considerations. Results highlighted job creation, income equality, and microfinance support as key social considerations, while energy-related criteria emphasized sustainable practices. The proposed multi-objective programming model and COmbined COmpromise SOlution (COCOSO) method facilitated the selection of eight projects, with one project as the top-ranked option across various scoring strategies. Overall, this research provides a nuanced roadmap for effective decision-making in renewable energy projects, offering insights into project strengths, weaknesses, and potential areas for improvement.

Hydrogen is emerging as a clean and renewable energy source indispensable to the realization of a carbon neutral society. Inspired by the prospect of sustainable and carbon-free energy supplies, hydrogen has been widely utilized in various combustion engines. This review article highlights recent progress in understanding hydrogen combustion chemistry in the gas phase. At first, the explosion limits of hydrogen-oxygen mixtures are discussed to demonstrate the intrinsically nonmonotonic kinetic behavior. Fundamental experiments of hydrogen combustion in terms of ignition delay times, laminar flame speeds and speciation are systematically summarized, and the value of the reported data is discussed. Furthermore, effective strategies towards more accurate experimental diagnostics are outlined. The current status of detailed and simplified kinetic model development is then appraised, followed by a critical discussion on the rate constants of important elementary reactions that are still in dispute. The essential importance of the comprehensiveness of chemical fidelity for mechanisms at the detailed and reduced levels is emphasized. Subsequently, the knowledge of ozone-assisted oxidation of hydrogen is overviewed. The effects of ozone addition on the characteristics of hydrogen oxidation are analyzed, including ignition temperature, flame burning velocity and flame structure. The ozone sub-mechanism and associated reaction rates are also carefully assessed. Finally, concluding comments and an outlook towards future research on gas-phase hydrogen combustion chemistry are presented.

In the natural gas era, an underground gas storage capacity of more than 10 trillion cubic feet has been developed globally. However, as the global energy demand shifts toward hydrogen, the potential for repurposing these storage facilities for hydrogen has not been systematically investigated. In the hydrogen era, failing to utilize this substantial volume could result in significant resource wastage. This study systematically analyzes the feasibility of Converting Underground Gas Storage (CUGS) for hydrogen for the first time. We establish a new conceptual framework by carefully exploring the reuse potential of surface facilities and evaluating the effects of reservoir environment changes. Based on these analyses, we summarize the advantages and challenges of this technical framework. In addition, an economic assessment is conducted by comparing the CUGS route with the traditional method of Converting Depleted Gas Reservoirs (CDGR) for hydrogen storage. Our results show that the CUGS route will face significant challenges, including water intrusion, geochemical reactions, leakage, and potential integrity damage. Nevertheless, it remains a rapid, stable, and low-cost method for underground hydrogen storage. In particular, our findings indicate that it can increase economic benefits by 3.1 times compared to the traditional CDGR route. Such evidence suggests that the CUGS route offers a large-scale, stable, and economical option for underground hydrogen storage, while also avoiding the abandonment of existing underground natural gas storage facilities in a future hydrogen-oriented society.
