The conversion of carbon dioxide (CO₂) into jet fuel holds significant potential for reducing CO₂ emissions, providing an alternative to carbon-based resources, and offering a renewable means of energy storage. The objective of this study is to conduct a techno-economic analysis and optimize the supply chain network for converting CO₂ to jet fuel in the United States, aiming to minimize total costs while assessing the environmental and economic feasibility of two CO₂ conversion pathways. This first pathway is based on Fischer-Tropsch synthesis (FTS), and the other one is based on the valorization and upgrading of light methanol (MeOH). Incorporating spatial and techno-economic data, a mixed-integer linear programming model was developed to select source plants and conversion pathways, locations of conversion refinery sites, and the amount of captured CO₂ across the United States. The optimal results indicate that the FTS pathway is adopted at all selected refineries when the hydrogen price is $1000/t and the operating cost, mainly electricity used in conversion, is reduced to 5 % of its current level. Under this scenario, the total annual profit is $8B and the net carbon emissions are −88,783,284 tons. The sensitivity analyses reveal that the prices of electricity and hydrogen significantly contribute to total production costs. The CO₂ recycle percentage of the FTS pathway influences the choice of applied pathways at refineries. Additionally, a higher conversion rate holds a substantial promise for reducing the total production cost and can make the MeOH pathway a viable choice.

Offshore energy system integration is particularly important for realising a rapid and cost-effective low-carbon energy transition in the North Sea region. Effective implementation of strategies that require collaboration between countries, developers and operators must be underpinned by robust and comprehensive modelling results. Intra-system interactions and diversity of sectors needed to facilitate the energy transition must be adequately captured within whole-system models. Historically, consideration of the offshore energy environment within macro-scale models has been supplementary to the onshore system. However, increased deployment of offshore wind, focus on geological storage for energy security, and technological development and investment in hydrogen and carbon storage projects highlights the importance of expanding the role of the offshore system within modelling. This study presents a comprehensive investigation of energy system integration challenges within offshore system modelling, and how these define the requirements of the employed methodology. The findings suggest large-scale offshore system modelling studies typically include few energy vectors, limited spatial resolution and simplified network flow characteristics. Despite the North Sea focus, these challenges reflect fundamental barriers within large-scale offshore energy system modelling and thus extend to similar offshore contexts globally. Key approaches are identified to maximise sectoral and technological diversity, while maintaining sufficient temporal and spatial resolution to suitably represent the evolving offshore system, are identified. We make concrete suggestions for future work in this field, based on identified best practice among the reviewed literature.

Bamboo construction materials are increasingly recognized in the construction industry as a promising path toward sustainable development, generating substantial interdisciplinary interest. However, previous research has often supported or criticized its sustainability in specific aspects through fragmented analysis. Comprehensive assessments that reveal the full scope of bamboo’s sustainability remain scarce. To address this gap, this research aims to: (1) conduct an in-depth and systematic review of research on bamboo construction materials and sustainability; (2) elucidate the contributions of bamboo construction materials to sustainable development; and (3) identify research gaps and propose future research directions. This study employs a systematic literature review methodology, examining 742 relevant articles published between 2000 and 2023. Specifically, this research evaluates the sustainability performance of bamboo construction materials from three thematic perspectives: social sustainability, economic sustainability, and environmental sustainability. It summarizes the current state of research and identifies research gaps. Ultimately, four future research directions are proposed, including the relationship between bamboo materials and health and well-being, genomic sequencing and editing technologies, policies and regulations, and life cycle assessment. Unlike previous studies, this research uniquely depicts a comprehensive landscape of sustainability research on bamboo construction materials. The results of this research contribute to revealing the relationship between bamboo construction materials and sustainability, examining knowledge gaps in the field, avoiding repetitive imitative research, and promoting the sustainable development of bamboo construction materials.

The early development of blue hydrogen is often proposed to ‘kick-start’ a hydrogen economy however, the volatility of the cost of gas, different emission intensities of blue technological options, and projected cost reductions in electrolysers could lead to stranded assets. We develop a model to interrogate the dynamics of hydrogen supply and demand using different cost trajectories for green and blue hydrogen production, and under different carbon pricing scenarios. We find that the window of opportunity for blue hydrogen is mostly determined by how quickly green hydrogen costs reduce. We show that blue hydrogen assets deployed within the next three decades are likely to be significantly underutilised, unless the cost of green hydrogen remains at the high end of projections. This analysis implies that there is a substantial risk that investments in blue hydrogen will lead to stranded assets, which could occur without high-quality information and clear policies.

The ethanol industries in the United States and China are witnessing a surge in the production of co-products, especially dried distillers' grains with solubles (DDGS). In the U.S., 90 % of maize-based ethanol byproducts are used for livestock feed, with 38.7 % of 14,575 million bushels repurposed in 2020. The U.S. also contributed 36 % of global maize shipments that year. China achieved a 98.2 % self-sufficiency rate in maize, producing 260.8 million metric tons and importing only 4.8 million metric tons in 2019. However, higher mycotoxin levels in DDGS, up to three times those in raw grain, cost the swine industry $9 million annually due to reduced weight gain from fumonisins. This review examines corn, DDGS, and ethanol production, spotlighting China and the USA. It addresses mycotoxin contamination in DDGS and corn, detailing its adverse effects on animal health. It also explores current challenges in DDGS mycotoxin contamination, focusing on processing, nutrition, and product quality. The propose future research directions to prevent mycotoxin contamination, ensuring a safer and more efficient industry. The increasing demand for animal products, climate change, and food safety issues highlight the need for improved food supply and diverse feed materials. Mycotoxin contamination poses significant health risks in feed. Modernizing detection methods for rapid, accurate results is essential to reduce economic losses. A comprehensive detoxification approach, including physical, chemical, and biological methods, is crucial. Ongoing research and strategic measures are vital to combat mycotoxin contamination, ensuring safe and efficient animal husbandry practices.

As an independent power source that can disconnect from the main grid during a power outage, microgrids continue to gain global popularity due to multiple benefits, including decarbonization and resilience. Nevertheless, their cost – compared to the conventional utility-scale grid – has limited their competitiveness and deployment. Finding ways to value the resilience microgrids provide during outages has become a key challenge for the sector and for advocates and developers hoping to justify the expense of investing in microgrids to public utility commissions. To understand and compare the various approaches being used to value resiliency from microgrids, this study conducted and analyzed 32 interviews with industry experts including companies, advocacy groups, national labs, non-elected officials, research institutions, and utilities working on grid resilience and on resilience valuation tools. A newly designed Timeline, Objective, Organization, Limitations, Services (TOOLS) framework is utilized to describe three selected resilience valuation metrics: Interruption Cost Estimate (ICE), Power Outage Economic Tool (POET) and Resilience Node Cluster Analysis Tool (ReNCAT). While these valuation tools provide important context, experts stressed that the definition of resilience is unique to every community. Valuing resilience is complex and current methods do not fully include difficult-to-quantify factors like equity or spillover economic effects of outages. Combining ongoing resilience valuation efforts can provide useful outcomes.

Solar power has gained popularity as an alternative to tackling global energy and environmental issues. However, concerns about the unpredictable nature of renewable energy sources, irregular behavior, and partial shading of solar panels hinder photovoltaic (PV) system stability and efficiency. Utilization of a solar charge controller (SCC) with pulse width modulation (PWM) and maximum power point tracking (MPPT) functionality is imperative to enhance the effectiveness and reliability of PV systems. Fluctuating external conditions make MPPT challenging, particularly under non-ideal operating conditions such as partial shading or temperature variations. Advanced MPPT control methods have been proposed to address these challenges, outperforming conventional algorithms. This study provides a comprehensive review and analysis of the control strategies employed in PWM and MPPT for PV systems. Each MPPT technique has pros and cons, but a streamlined approach considers cost, accuracy, complexity, speed, analog/digital, and efficiency. The intent is to contribute to the widespread adoption of the MPPT technology and address the challenges associated with PV system implementation. Through diligent research efforts, MPPT systems improved efficiency in managing renewable power generation intricacies. Utilizing advancements in SCC with PWM and MPPT enhances energy harvest, increases system reliability, prolongs battery life, and improves solar energy system performance. The fundamental discoveries are condensed in advancing progressively resilient controllers for enhanced efficiency, reliability, stability, protection, and nations. This work aids the transition to clean energy systems and provides a foundation for selecting the most effective MPPT controller for future research direction toward sustainable development.

Housing accounts for a high proportion of our anthropogenic greenhouse gas (GHG) emissions and represents a large environmental footprint, particularly when supporting infrastructure and transportation are included. This review introduces three housing life cycle assessment (LCA) frameworks, which are distinguished by the spatial scope of analysis and built environment elements included. The choice of housing LCA framework has possible tradeoffs affecting the environmental impact quantification and selection of lower impact housing built form or housing development type. The objective of this systematic review is to compare previous standard housing LCAs, holistic housing LCAs, and neighborhoods LCAs related to the four stages of LCA (goal and scope definition, life cycle inventory, impact assessment, and interpretation). This paper presents quantitative analyses of housing GHG emissions from the reviewed studies which indicate that standard housing LCA underestimates average GHG emissions by 43 % due to exclusion of mobility, and by 11 % due to exclusion of open spaces, and networks. The interpretation of which housing built form has lower GHG emissions switches between standard and holistic housing LCAs. This review recommends the use of holistic housing and neighborhood LCAs to fully assess the environmental impacts of early-stage housing and neighborhood planning. However, these frameworks require standardization, including functional unit definition, scoping of system boundary, and treatment of temporal uncertainty and variability in housing contexts.

Sustainable development has become a core part of all day-to-day activities and considerations because of the critical role it plays in determining the future. This research explores the potential contribution of green education in achieving the sustainable development goals. To achieve this objective, this study relied on a narrative/traditional literature review as the methodology. Drawing on recent research, the review established that green education plays an influential role in achievement of sustainable development goals in several ways. A synthesis of the findings of multiple studies on the relationship between green education and sustainability reveals that the main contribution of green education to achieving these goals is through societal and behavioral change, which is achieved through the universal inculcation of climate change awareness. Consequently, this study concludes that green education could play a stronger role in attainment of sustainable development goals. However, securing this role will be difficult because of vast environmental and climatic changes that are anticipated in the future. To this end, impediments that minimize educational impact are also discussed in this research, along with proposed lessons on the way forward and the implications for future research in this area.

A synthesis of the findings of multiple studies on the relationship between green education and sustainability reveals that the main contribution of green education to achieving these goals is through societal and behavioral change, which is achieved through the universal inculcation of climate change awareness. Consequently, this study concludes that green education could play a stronger role in attainment of sustainable development goals. However, securing this role will be difficult because of vast environmental and climatic changes that are anticipated in the future. To this end, impediments that minimize educational impact are also discussed in this research, along with proposed lessons on the way forward and the implications for future research in this area.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"210 ","pages":"Article 115239"},"PeriodicalIF":16.3,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143171023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Renewable energy needs to be expanded because it is important for sustainble development. There is the need to study the importance of factors that drive renewable energy. This study mainly focuses on assessing the impact of green technology (GTI), research and development (RDT), and the digital economy (DEC) on renewable energy innovation (RENT) in BRICS countries. The study used FMOLS and DOLS as the main econometric methods to determine the long-run empirical estimates from 2000 to 2022. The research is expected to provide important implications to policy planners as to how they should expand the scope of renewable energy. The findings of the study are as follows: (1) Green technology positively influenced RENT in BRICS countries. (2) The study documented a positive relationship between RDT and RENT. (3) The DOLS analysis shows that the DEC fosters renewable energy companies. (4) The findings also indicate a negative correlation between DEC and RENT in BRICS countries. It is recommended that policymakers in BRICS economies formulate and execute policies that promote green technology advancement, research, and development initiatives, and foster digital economy integration to spur renewable energy innovation.
