Summary: With the development of renewable energy sources, integrating energy storage systems within microgrids has become a focus of attention. Hydrogen systems are considered a promising energy storage option that utilizes electrolysers to produce and store hydrogen, which can be supplied back to microgrids using fuel cells. Designing an energy management system is crucial for controlling the energy flow within hybrid energy systems and optimizing the operation of microgrids. This study provides a comprehensive review and analysis of energy management systems for hydrogen technologies-based microgrids, including objectives, constraints, techniques, optimization methods, and simulation tools, as well as discussing challenges and future research directions.

Summary: The digital economy has become a new driving force for economic growth in various countries. Research on China's digital economy development and green total factor productivity shows that the digital economy has a positive direct impact and spatial spillover effect on green total factor productivity, mainly through promoting green technology progress. Industrial structure upgrading and factor market distortion are the two primary channels through which the digital economy affects green total factor productivity.

Summary: Although operational activities in the aviation sector inevitably bring more emissions, they also reshape the structure of the regional economy, often leading to a shift from emission-heavy industries to cleaner service sectors. The overall impact of aviation network development on the region's environmental trajectory is unclear and requires rigorous empirical study. Using data from 283 Chinese prefecture-level cities, this paper calculates a comprehensive carbon lock-in index to measure cities' reliance on emission-heavy sectors and resistance to emission reduction. The empirical results suggest that an improved aviation network development helps alleviate carbon lock-in through mechanisms such as fixed input, industrial structure upgrading, and technological innovation.

Summary: This paper explores different types of hydrogen production and assigns each a different color to represent a gradual reduction in pollution. The basic principles, advantages, and disadvantages of various production methods are examined at a technical level. The study concludes that coal-based hydrogen production is currently the primary method in China, while converting brown and grey hydrogen to blue and turquoise hydrogen is more economically viable as CCUS technology matures. The challenges for green hydrogen lie in electrolyzer technology and high renewable power costs, which can be addressed by increasing hydrogen production using wind and light abandonment in the short term and transitioning to renewable energy generation for clean hydrogen production in the long term. Vigorously developing hydrogen fuel cell vehicles and reducing greenhouse gas emissions in transport are crucial for achieving carbon neutrality and ensuring a stable supply of blue and green hydrogen.

Summary: Global warming is a critical issue extensively discussed by mankind, caused by greenhouse gases, mainly CO2, produced from our fossil fuel-based energy economy. The resulting climate change has severe consequences on the environment, such as increased frequency and intensity of natural disasters. Without keeping the average temperature rise below 1.5 K by the end of the century, climatologists predict disastrous events including a significant rise in sea level and shift of climate zones. This article presents the historical evolution of anthropogenic CO2 emissions and discusses technically feasible measures and an alternative world energy economy based on renewable energies and hydrogen/electricity as secondary energy sources. It also addresses the question of whether necessary measures can be implemented under the dominant neoliberal capitalistic system or if a dysfunctional dystopian future becomes inevitable.

Summary: Previous literature on improving environmental efficiency has focused on the role of the government and neglected the contribution of public participation represented by environmental non-governmental organizations (ENGOs). This paper evaluates the effectiveness of public participation using a quasi-natural experiment generated by the Institute of Public and Environmental Affairs (IPE) in China. The empirical results show that environmental efficiency in cities with environmental information disclosure improves by 21.11% compared to cities without such disclosure. However, this improvement diminishes in the long-term. The study also demonstrates that controlling pollutant emissions is the main mechanism for enhancing environmental efficiency. Moreover, the effects of public participation are more prominent in eastern, developed, large, and non-resource-based cities. These findings highlight the importance of public participation in green development and provide empirical evidence for a diversified environmental governance system.
