Adoption of Rooftop Solar Power as an Energy Option: A Household Level Study in Pune Smart City

Power generation using fossil fuels on a large scale contributes to global greenhouse gases and, therefore, impacts climate change. Renewable energy sources like solar power are needed to overcome such adverse impacts. Solar energy has received attention in the recent years due to both technological improvements resulting in cost reductions as well as the government policy push for renewable energy development and utilization. This research concerns with the adoption of rooftop solar power as an energy option at household level in the context of smart cities. We conducted a questionnaire survey on a sample of resident households in Pune smart city and analysed various parameters concerning households’ adoption. It has been found that the respondents are less willing to adopt rooftop solar power option for the lack of awareness of energy conservation and climate change issues, lack of financial incentives for the adoption and concern for operational issues that arise after the adoption; the respondents who are aware are more likely to adopt it in a timeframe of 1–3 years. Statistical analysis of various important relationships may be useful for future research on household adoption of renewable energy options, such as rooftop solar power.

Financial subsidy optimization to promote renewable energy development for sustainable development goal

Enhancing the efficacy of financial subsidies holds paramount significance in fostering sustainable development due to their influence on energy utilization, installation scalability, and the crucial pursuit of decarbonization. Despite a surge in scholarly interest surrounding financial subsidies for renewable energy, the literature studies fall short in comprehensively addressing the factors that impact on the accuracy and reliability of the model for identifying optimal financial subsidies. This paper introduces a robust approach to optimize financial subsidies to achieve the predefined target for renewable energy installation, considering the equilibrium between investor remuneration and government subsidy outlay. Center to this approach is the integration of a forward-looking price forecasting model and the establishment of an economic evaluation approach based on empirical data encompassing weather patterns, technical factors, investor expectations, subsidy disbursements, market risk assessments, and other pertinent parameters. The case study of Taiwan is conducted, and the results indicate that, in the baseline scenario, the financial subsidy is only effective in the risk-neutral market with a small solar system; in the mix scenario, the benefit of energy system increased at least 4.5%, however, the mix scenario is still ineffective to encourage the renewable energy development; and in the optimal scenario, by providing accurate recommendations for optimal financial subsidies, government can achieve the predefined target, even with reduced subsidies due to declining installation costs.

Photovoltaic Power Station Impacts on the Benthic Ecosystem and Sediment Carbon Storage in Tidal Flats in China.

Photovoltaic power is a rapidly growing component of the renewable energy sector. Photovoltaic power stations (PVPSs) on coastal tidal flats offer benefits, but the lack of information on the effects of PVPSs on benthic ecosystems and sediment carbon storage can hamper the development of eco-friendly renewable energy. We sampled the macrobenthos and sediment cores at a PVPS on a coastal tidal flat in eastern China. The biodiversity indicators and benthic ecological quality based on macrobenthos were mostly higher under the photovoltaic panels than elsewhere. These variations were primarily driven by pH, sediment grain size, and chlorophyll-a content. However, the PVPS had exerted a considerable influence on the macrobenthic community structure. Furthermore, the carbon stocks in the sediment cores from under the photovoltaic panels were similar to those in the reference sites. These results suggest that this PVPS has not had discernible short-term adverse effects on the benthic ecosystems or sediment carbon storage of the tidal flat. Nevertheless, the potentially long-term and cascading risks throughout the ecosystem warrant caution. Therefore, we recommend that policymakers adopt a cautious development strategy and implement long-term, high-frequency monitoring to ensure the sustainability of renewable energy production on coastal tidal flats.

Latent Information in the Evolving Energy Structure

Recent studies indicate that Artificial Intelligence (AI) technology, characterized by its integration of information and communication technology attributes, exerts a multifaceted influence on the energy system. The authors employ Difference-in-Differences (DID) and Triple-Difference (DDD) models to investigate the effects of AI. The research initially demonstrates that AI may exhibit dual attributes of constraining energy structure. Specifically, the rapid development of AI tends to increase the proportion of fossil fuel-based electricity generation while optimizing the consumption of renewable energy. Furthermore, the degradation of energy structure stems from the surge in electricity consumption by AI, which the renewable energy consumption capacity is unable to satisfy. Lastly, industrial agglomeration effects and the construction of the digital economy have positive impacts on development of renewable energy; technological innovation aids in mitigating the negative shocks to the energy structure. This study provides a new perspective on the role of AI technology in energy transition.

The Interplay Between China’s Regulated and Voluntary Carbon Markets and Its Influence on Renewable Energy Development—A Literature Review

This is the first review study that focuses on the interplay between China’s regulated and voluntary carbon markets, the Emissions Trading System (ETS), the China Certified Emission Reduction (CCER) scheme, and their combined influence on the development of renewable energy in the country. Through a comparative literature review of 52 peer-reviewed academic papers published between 2009 and 2024, this study aims to elucidate how these market mechanisms interact to drive renewable energy deployment. The findings indicate that both the ETS and the CCER system positively affect China’s renewable energy landscape. The ETS, with its Cap-and-Trade (CaT) mechanism, sets a cap on total emissions and allows for the trading of emission quotas, thereby creating financial incentives for companies to reduce emissions and invest in renewable energy. The CCER scheme complements the ETS by allowing companies to use the CCER scheme for a capped share of their ETS certificates, whereby the lower CCER price diverts investments to where the saved ton of CO2 in China is cheapest, further incentivizing investments in renewable energy. This dual mechanism allows for a more flexible and cost-effective approach to achieving emission reduction targets, thereby fostering an environment conducive to investment in renewable energy. It will stimulate additional investment in renewable energy projects in the long run, particularly in economically underdeveloped regions, contributing to both local economic development and national emission reduction targets.

Financial component of the hydrogen economy development strategy of Ukraine

The relevance of the study is determined by the need to detail the financial justification of the development of the hydrogen economy in Ukraine, taking into account the need to ensure energy independence and diversification of energy resources. With a sufficient number of publications on the innovativeness of hydrogen technologies, global trends in their use and the importance of decarbonization of public production, the issue of financial support for the development of the hydrogen economy remains insufficiently covered. The purpose of the article is to highlight and characterize the financial component of the strategy for building the hydrogen economy of Ukraine. To achieve the goal, general and special methods of scientific research were used: abstraction, decomposition, comparison, analysis, extrapolation. According to the results of the study, a derived relationship between the number of scientific studies on the development of hydrogen technologies and the state of the energy market was revealed, which made it possible to put forward a hypothesis about the intensity of research on the prospects for the development of the hydrogen economy in the context of the adequacy of its financing. The existing hydrogen technologies can be applied only in connection with the development of renewable energy, they require increased innovations in production, infrastructure, and consumption of hydrogen, therefore, they require increased financing. The financial component of the Hydrogen Strategy of Ukraine (until 2050), developed by the Ministry of Energy, is highlighted at each stage of its implementation. The foreign experience of strategies for the development of the hydrogen economy is presented and the insufficiency of financial resources to ensure the achievement of the target indicators of the Ukrainian strategy, especially in the conditions of war, is stated. The relationship between the Hydrogen Strategy of Ukraine and the Recovery Plan of Ukraine until 2032 is characterized. The general need for financing the development of the hydrogen economy at the second stage of the implementation of the Hydrogen Strategy was determined in connection with the content of the pilot projects. Accordingly, there is a need to detail the focus and sources of funding for the hydrogen economy development strategy in Ukraine, potential sources of cash receipts, changes in institutional and regulatory support for the hydrogen strategy.

Physical–Chemical–Biological Pretreatment for Biomass Degradation and Industrial Applications: A Review

Lignocellulosic biomass, including agricultural, forestry, and energy crop waste, is one of Earth’s most abundant renewable resources, accounting for approximately 50% of global renewable resources. It contains cellulose, hemicellulose, and lignin, making it crucial for biofuels and bio-based chemicals. Due to its complex structure, single-pretreatment methods are inefficient, leading to the development of combined pretreatment technologies. These methods enhance cellulose accessibility and conversion efficiency. This paper analyzes the principles, advantages, and disadvantages of various combined pretreatment methods and their practical benefits. It highlights recent research achievements and applications in biofuel, biochemical production, and feed. By integrating multiple pretreatment methods, biomass degradation efficiency can be significantly improved, energy consumption reduced, and chemical reagent use minimized. Future advancements in combined physical, chemical, and biological pretreatment technologies will further enhance biomass utilization efficiency, reduce energy consumption, and protect the environment, providing robust support for sustainable renewable energy development and ecological protection.

Dynamic impact of green finance on renewable energy development: Based on scale, structure, and efficiency perspectives

Utilizing China's provincial panel data from 2003 to 2021, this paper employs a dynamic panel quantile regression model and mediating test model to investigate the dynamic evolution characteristics, type heterogeneity, and mechanism of green finance (GF) driving renewable energy development (RED) in China, considering the scale, structure, and efficiency of GF. The findings of this study are as follows. While the scale, structure, and efficiency of GF all contribute to the promotion of RED, the impact of green financial structure is particularly significant. As renewable energy continues to develop, the impact of green financial scale and green financial structure gradually diminishes, while the effect of green financial efficiency increases. In comparison to hydropower and solar power, GF has the strongest promotion effect on wind power, and the marginal effect of green financial scale and green financial structure on wind power follows a U-shaped trajectory. The driving of GF on RED is mainly through direct effect, supplemented by indirect effect. In the mechanism by which GF impacts RED, the channels associated with green attributes are relatively smooth. Based on these research conclusions, this paper offers policy recommendations aimed at enhancing RED through GF from perspectives encompassing scale, structure, and efficiency.

Utilization of High-Salinity Crude Glycerol Byproduct from Biodiesel Production for Biosynthesis of γ-Aminobutyric Acid in Engineered Halomonas elongata

As the development of renewable energy has become imperative, biodiesel fuel (BDF) has been used as renewable biofuel with the advantage of having lower levels of greenhouse gas emissions. However, the transesterification reaction that produces BDF generates a high-salinity crude glycerol (CG) byproduct, which is difficult to recycle. Halomonas elongata is a moderately halophilic bacterium being used as a cell factory due to its ability to assimilate varieties of substrates for growth in high-salinity conditions. Previously, we engineered a recombinant H. elongata GOP-Gad to biosynthesize and accumulate γ-aminobutyric acid (GABA) as a high-value product. Here, we tested the ability of H. elongata GOP-Gad to use CG as a substrate for cell growth and GABA production. The CG byproduct was obtained from a BDF facility in Unzen City, Nagasaki, Japan, where geothermal energy catalyzed BDF production from waste cooking oil and biomethanol. Prior to use as the sole carbon (C) source in culture media, the CG byproduct was partially purified to remove soap substances and other impurities. Finally, we showed that H. elongata GOP-Gad could grow and accumulate GABA up to 28 μmol/g cell fresh weight in a minimal M63 medium containing 7% w/v NaCl with 4% w/v glycerol from the partially purified CG as a C source and 15 mM (NH4)2SO4 as a nitrogen (N) source. This result demonstrates a new circulatory bioprocess of C and N, in which H. elongata GOP-Gad can use partially purified CG and (NH4)2SO4 as the sole C and N sources for growth and GABA production.

Can green trade development promote energy security in China? The role of financial development

Energy security is an essential component of overall national security. This paper investigates the impact of green trade (GRTR) on China's energy security and financial development's role in this nexus. The energy security evaluation index in this study is constructed from availability, applicability, acceptability, and affordability (the 4-As) and calculated by employing the Improved Entropy Method (IEM). Based on the two-step robust system-generalized method of moments (SYS-GMM) and data from China's 30 provinces between 2004-2020, this article investigates the impact of GRTR on energy security, the moderating effect of financial development and the impact mechanism of renewable energy development on the GRTR-energy security nexus. Our econometric analysis results indicate that increased GRTR can notably enhance energy security, and financial development can strengthen the positive impact of GRTR on energy security. The advancement of GRTR contributes positively to enhanced energy availability, acceptability, and affordability, but it could potentially decrease progress in the applicability of energy security; the promoting effect of GRTR on energy security in low-GRTR areas will be limited. The results of the mediating mechanism indicate that GRTR can accelerate energy security growth through renewable energy development. These insights provide policy implications for combining GRTR incentives to promote energy security.

National goal, local resistance: How institutional gaps hinder local renewable energy development in Taiwan

In most countries, energy transitions are well supported by the public; however, the implementation of renewable energy policies at the local level is often beset with resistance. Previous research has mainly focused on factors influencing community acceptance and strategies to improve social acceptance. Meanwhile, there has been limited analysis of the institutional gaps that lead to local resistance and the dynamic effects of institutional factors on renewable energy implementation at the local level. This paper thus investigates Taiwan's regulations for renewable energy development, presenting a detailed case study from a local context. It examines the factors contributing to local resistance to the implementation of national renewable energy policy targets and explores the dynamics of these resistance actions. Furthermore, through the lens of multi-level governance, the study reveals the institutional gaps and interactions that influence the execution of national policy at the local level. Six major institutional gaps in Taiwan's renewable energy governance were identified, including the lack of energy governance authorizations for local governments, a lack of superordinate site selection criteria and evaluation mechanisms for development zones, lack of governance systems that can address multiple issues, lack of scientific and academic information, lack of information disclosure and public participation mechanisms, and the burden of carbon reduction responsibilities and costs on local communities with few or no benefits. Compounded together, these six institutional gaps lead to the buildup of negative experiences interacting with the government and the renewable energy industry and feelings of worry, panic, distrust, and injustice among the local populace. These ultimately trigger resistance attitudes and the adoption of protest actions, hindering solar farm developments from reaching national policy targets. This study highlights the critical role of multi-level governance in facilitating the energy transition, emphasizing that the successful development of renewable energy requires a robust institutional framework. Such a framework is essential for addressing the complex governance challenges that arise during this transition, particularly aspects supporting local engagement. The six institutional gaps identified from the Taiwan case can serve as policy references for countries or cities intending to promote ground-mounted solar power.

Efficient H2 evolution over MoS2-NiS2/g-C3N4 S-scheme photocatalyst with NiS2 as electron mediator

Low-cost transition metal sulfides are commonly utilized as photocatalysts for H2 production owing to their exceptional conductivity and superior specific surface area. In this study, MoS2-NiS2 nanoflowers with multidimensional space structure was obtained through the sulphuration reaction between S2- and NiMoO4 under Kirkendall effect during hydrothermal reaction. Subsequently, MoS2-NiS2 was loaded on the surface of g-C3N4 nanosheets using a solvent self-assembly strategy to form 3D MoS2-NiS2/g-C3N4 heterojunctions. The experimental results demonstrate that the H2 production rate of 20 wt% MoS2-NiS2/g-C3N4 reaches 22153 μmol·g-1·h-1 under a 300 W Xe lamp irradiation, which is 59.5 and 201.4-folds than MoS2-NiS2 and g-C3N4, and surpasses 20 wt% MoS2/g-C3N4 (211 μmol·g-1·h-1) and 20 wt% NiS2/g-C3N4 (6183 μmol·g-1·h-1). The XPS and Superoxide radical capture experiments demonstrate that the charge transfer between MoS2-NiS2 and g-C3N4 follows the S-scheme route, and NiS2 functions as an electron mediator, facilitating the transfer of electrons from MoS2 to g-C3N4 to consume the holes, which enhances the efficiency of H2 evolution reaction on g-C3N4. Furthermore, the S-scheme heterojunction of MoS2-NiS2/g-C3N4 with the multidimensional geometric structure can provide abundant active sites for catalytic reactions, this presents a promising approach for the development of cost-effective and high-performance g-C3N4-based heterojunctions. This work offers distinctive perspectives on the trajectory of renewable H2 energy development.

Optimal Dispatch of Coal-fired Power Units with Carbon Capture Considering Peak Shaving and Ladder-type Carbon Trading

In the context of the low-carbon transformation of the power system, carbon markets, and carbon capture technologies have become important means to promote energy conservation and emission reduction. The rapid development of renewable energy poses a challenge to the regulation capability of the power system, and energy storage technology is currently an important means to enhance the regulation capability of the power grid. To reduce the carbon emission level of the power system, improve the system economy and the ability to consume renewable energy, this paper proposes a multi-energy complementary system (MECS) with carbon capture power plant (IFCCPP) considering ladder-type carbon trading (LCT) and energy storage. The optimal dispatch model was developed with the objective of minimizing the overall operating cost. The results indicated that the integration of IFCCPP and LCT has better economic and environmental benefits than separate applications. The integration of the two modes can reduce the total cost by 504.33 k$ and carbon emission by 39232.63 t, which verifies the rationality of integrating the two modes. The LCT produces more significant emission reduction effects due to its higher benefits when carbon emissions are lower. The traditional carbon trading mechanism reduces 4779.88 t of carbon emissions, and LCT reduces 38574.45 t.

The role of hydrogen in the synthesis of High-entropy alloys and their hydrides

The aim of this work is to present the new technique processes of formation of stable hydrides of High-entropy alloys (HEAs) with high hydrogen content. The essence of the proposed method is the sequential use of self-propagating high-temperature synthesis (SHS) method for producing the metal hydrides, followed by the formation of alloys in the hydride cycle (HC) method. Preliminary, the hydrides of three compositions of metal mixtures were synthesized in SHS: 0.2TiH2+0.2ZrH2+0.2HfH2+0.2VH2+0.2NbH2, 0.3TiH2+0.15ZrH2+0.15HfH2+0.2VH2+0.2NbH2 and 0.3TiH2+0.1ZrH2+0.1HfH2+0.2VH2+0.2NbH2+0.1MgH2. From the synthesized mixtures of metal hydrides, the HEAs were produced in HC. The resultant hard alloys Ti0.2Zr0.2Hf0.2V0.2Nb0.2, Ti0.3Zr0.15Hf0.15V0.2Nb0.2 and Ti0.3Zr0.15Hf0.15V0.2Nb0.2Mg0.1 without crushing combusted in Н2 at РH2 = 5-30atm. in SHS mode. As a result, the hydrides of HEAs (Ti0.2Zr0.2Hf0.2V0.2Nb0.2)Н2.05, (Ti0.3Zr0.15Hf0.15V0.2Nb0.2)H2.05 and (Ti0.3Zr0.1Hf0.1V0.2Nb0.2 Mg0.1)H182 were synthesized with H2 content between 2.17-2.42wt.% and H/Me = 1.82-2.05. The repeating the hydrogenation-dehydrogenation processes for 1-3 times confirmed the exceptional cyclic stability of hydrides and the reversible high hydrogen storage capacity of the alloys. The regularities and the mechanism of formation of HEAs and their hydrides were elucidated. The applicability of combination of SHS and HC methods for synthesis of solid solutions of BCC structure HEAs and of their hydrogen-rich hydrides was demonstrated. The remarkable advantages of the developed efficient, low-energy consuming, waste-free and safe method for the synthesis of HEAs and their hydrides can be of commercial interest and attractive to industry, given the current needs for the development of renewable energy, in particular, the solid hydrogen storage facilities.

Optimization Scheduling of Off-grid Hybrid Renewable Energy Systems Based on Dung Beetle Optimizer with Convergence Factor and Mathematical Spiral

With the rapid development of renewable energy and the increasing modernization demands in remote areas, off-grid hybrid renewable energy systems (HRES) have become a key technology for achieving sustainable development. This paper presents an improved Dung Beetle Optimization (DBO) algorithm that enhances step size by introducing six elementary functions as convergence factors. It combines polar coordinate expressions of three different mathematical spirals, multiplied by a zeroing factor related to the number of iterations, resulting in six distinct mathematical images that optimize the algorithm's dancing path, thereby enhancing global search capability. Experiments on the CEC2022 test functions demonstrate improved optimization performance of the algorithm. Furthermore, the algorithm is applied to the optimization design of off-grid HRES, integrating configurations such as photovoltaic panels, wind turbines, biomass generators and various battery types (Lead Acid battery/Lithium-Ion/Nickel-Iron), with lifecycle cost as the objective function while assessing energy costs. The results indicate that the nickel-iron battery system optimized by the improved DBO algorithm achieves the lowest lifecycle cost ($961,139) and energy cost ($0.3607/kWh), requiring a total of 1,329 PV panels, no wind turbines, and 268 nickel-iron battery units.
