Purpose This paper aims to review the role of government initiatives for developing clean fuels in India, decarbonize the transport sector and maximize the use of renewable sources of energy. India’s socio-economic prosperity is dependent on modern energy. The authors examine the role of biofuel in India’s emerging fuel mix. Design/methodology/approach A 20-year timeframe between 2000 and 2021 was set to learn about the subject and find the existing gaps. Of the 40 research papers, the authors found using keywords and delimiting criteria in the database, the authors have shortlisted 21 papers, which provided the theoretical framework for the study. Additionally, the authors used the government database to develop future projections using compound annual growth rate and trend analysis. Findings The study findings suggest that India should strictly implement the Biofuel Policy to promote indigenous production of biofuel to enhance affordability and accessibility. With blending options available with biofuels and biogas, the country can replace the right proportion of fossil fuel use by 2050. It will not only decrease India’s import dependence but also will create new job opportunities, specifically in tribal and remote locations and promote green energy mix. With emerging options like electric vehicle and hydrogen, the transport sector could be decarbonized to a greater extent. Social implications Indigenous cleaner fuel adoption and transport sector will generate additional employment and cut down fossil fuel import. Financial savings through reduced fossil fuel import will be directed toward social development. Originality/value The paper carries out critical analysis for the active use of modern green fuels in the present and coming days. Such unique analysis must help India to balance its energy basket.

This paper reviews the economic and managerial literature on the relationship between energy-ICT and the development of the green energy economy. It is summarized that there are four lines of existing literature on energy-ICT: cost and benefit analysis, fair competition issues, cybersecurity issues, and promotion policy issues. Even though ICT is energy-consuming, most of the existing empirical studies support the idea that energy-ICT has net positive effects on energy savings, energy efficiency improvement, emission reduction, and economic growth at both enterprise and economy-wide levels. Energy-ICT equips the platform operator with higher bargaining power, such that a governance mechanism to assure the fair access right of each entitled participant is required. A smarter energy-ICT network also becomes riskier, and hence the cybersecurity protection is more important than before. Future research and development opportunities remain on these issues of the fair competition, cybersecurity, and promotion policy of energy-ICT.

The transition to a low-carbon power system is among the measures to forge green energy transition and carbon neutrality, where grid firms have a crucial role. In this context, this paper uses the provincial data from 2004 to 2017 to evaluate the impact of market power of grid companies on service quality in China. Panel dynamic ordinary least square (DOLS) and fully modified ordinary least square (FMOLS) models are employed. The findings indicate that higher market power has indeed reduced reliability measured by average outage duration. Renewable energy integration also has negative effects and reduces electricity reliability. Finally, the effects are also heterogeneous across the different regions. The results may also provide useful lessons for other developing countries aiming to improve the electricity supply chain.

The purpose of this research was to derive promising technologies for the transport of hydrogen fuel cells, thereby supporting the development of research and development policy and presenting directions for investment. We also provide researchers with information about technology that will lead the technology field in the future. Hydrogen energy, as the core of carbon neutral and green energy, is a major issue in changing the future industrial structure and national competitive advantage. In this study, we derived promising technology at the core of future hydrogen fuel cell transportation using the published US patent and paper databases (DB). We first performed text mining and data preprocessing and then discovered promising technologies through generative topographic mapping analysis. We analyzed both the patent DB and treatise DB in parallel and compared the results. As a result, two promising technologies were derived from the patent DB analysis, and five were derived from the paper DB analysis.

In the context of the complete phase-out of lignite-fired power plants and the corresponding surface mines, the central priority is to ensure a fair development transition for the lignite mining areas. In the context of the installation of renewable energy system projects in the surface lignite mines of Western Macedonia, this paper aims to analyze the challenges for developing photovoltaic projects in areas with different characteristics and to propose solutions for selecting suitable areas, based on corresponding analysis. The investigated parameters cover a wide range of spatial criteria. The results contribute to a pragmatic transition to green energy generation involving a circular economy and sustainable development.

Abstract With the acceleration of urbanization, cities are the main targets for carbon neutrality and urban energy is the terminal of energy consumption and the integration point of various energy systems. Therefore, there is a need to promote the development of urban green energy and achieve low input and high output to achieve a low-carbon economy in cities. Previous studies have not considered the input–output efficiency of urban green-energy development. This study fills this gap. Based on the economic–energy–environmental framework, an input–output efficiency-evaluation index system for urban green-energy development was constructed. Based on improved data-envelopment analysis, a comparative evaluation of the input–output efficiency of green-energy development was carried out in 30 provinces in China in 2019. Considering the differences in regions, the development of urban green energy in different provinces was classified. From the perspective of a low-carbon economy, economic growth factors and environmental constraint factors were set. Together with the generalized Divisia index approach, the input–output efficiency optimization directions of urban green-energy development were obtained. The results showed that the input–output efficiencies of urban green-energy development in Jiangsu, Zhejiang, Fujian, Inner Mongolia, Ningxia and other provinces and cities were relatively high. Provinces with faster economic development and higher environmental carrying capacity have advantages after optimization and will become pilot areas for the development of urban green energy. This research provides a reference for the development of urban green energy in various provinces from the input and output perspective.

The electrical energy storage system faces numerous obstacles as green energy usage rises. The demand for electric vehicles (EVs) is growing in tandem with the technological advance of EV range on a single charge. To tackle the low-range EV problem, an effective electrical energy storage device is necessary. Traditionally, electric vehicles have been powered by a single source of power, which is insufficient to handle the EV’s dynamic demand. As a result, a unique storage medium is necessary to meet the EV load characteristics of high-energy density and high-power density. This EV storage system is made up of two complementing sources: chemical batteries and ultracapacitors/supercapacitors. The benefits of using ultracapacitors in a hybrid energy storage system (HESS) to meet the low-power electric car dynamic load are explored in this study. In this paper, a HESS technique for regulating the active power of low-powered EV simulations was tested in a MATLAB/Simulink environment with various dynamic loading situations. The feature of this design, as noted from the simulation results, is that it efficiently regulates the DC link voltage of an EV with a hybrid source while putting minimal load stress on the battery, resulting in longer battery life, lower costs, and increased vehicle range.
