Summary: Climate change is a major global challenge, and automakers have introduced fuel cell electric vehicles (FCEVs) as a more eco-friendly alternative. However, the market share for FCEVs is still far below target levels despite government policies and collaborations. This paper explores the growth of the FCEV market and analyzes the effects of contracts and government incentives, finding that incentives supporting capital costs are more effective in the startup phase while consumer-oriented and operating cost-based incentives drive market demand and growth. Relying solely on government incentives is not enough for market growth, and contracts are necessary to reach target market size.

Summary: This paper proposes an adaptive energy management strategy (A-EMS) based on speed forecasting for a heavy-duty fuel cell hybrid electric vehicle (FCV) to achieve stable battery charge sustenance in realistic driving conditions. The A-EMS integrates a validated and optimized fuel cell system model and a short-term velocity prediction layer using a LSTM neural network. The results show that A-EMS improves battery charge sustaining compared to the standard ECMS (S-ECMS) in real driving conditions.

Summary: New energy vehicles such as electric vehicles (EVs) and hydrogen fuel cell vehicles (HFCVs) are being developed to replace internal combustion engine vehicles and fossil oil. A comparative analysis reveals that electric passenger vehicles have more advantages in terms of economy, safety, and environmental impact, while hydrogen fuel cell passenger vehicles face significant obstacles. However, hydrogen fuel cell commercial vehicles have unique application scenarios. The dislocation and complementarity principle should be considered when implementing EVs and HFCVs in different scenarios.

Summary: This paper investigates the impact of the number of working points and response speed on the hydrogen consumption of proton exchange membrane fuel cell (PEMFC) at the system level. A dynamic model is established and verified by experiments, showing that the increase in working point number and response speed can reduce hydrogen consumption. However, the reduction range tends to reach an optimal level considering the trade-off with other costs.

Summary: This study used FLACS software to model hydrogen leaks and diffusion from tube fittings of hydrogen systems. The results showed that in windless conditions, the high concentration region was mainly around the group of hydrogen storage tanks, and there was no flammable region in the entire chassis area. Wind can accelerate hydrogen diffusion and reduce the extension range of the hydrogen envelope. Cutting off the hydrogen supply can rapidly contract the hydrogen envelope.

Summary: This paper examines the impact of real-time pricing and load automation on residential distribution systems. The study finds that implementing real-time pricing can result in an aggregate welfare gain of 39 USD per customer and year. However, it also notes that RTP and load automation may significantly increase peak system load. Introducing a market-based demand management system can further enhance welfare gains and reduce grid investment.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.

Summary: Russia's weaponization of gas supplies shook the energy security of Central and Eastern Europe in 2022. The region responded by increasing alternative energy supplies and developing new gas supply routes. Renewable energy, nuclear energy, and hydrogen play important roles in the long-term. Mitigating the impact of this shock requires the EU to prioritize the integrity of its energy market.

Summary: Economic costs are a major political obstacle to investing in climate change mitigation and adaptation measures. The method of financing plays a crucial role in determining public opposition to government green investments, with debt financing being less opposed than broad-based taxes. This study suggests that credit market tools, such as green bonds and debt for climate swaps, can be politically efficient in increasing support for green financing. Carbon taxes and wealth taxes are found to be the most preferred options.

Summary: This paper investigates China's energy trade stability using a survival analysis approach. It finds that the energy trade linkages between China and 153 other countries are complex and unstable, with short periods of trade with many countries. Geopolitically risky regions, such as the Middle East and Africa, have the lowest trade stability. Climate risks have significant effects on energy trade stability. The paper proposes several policy options to improve energy trade stability in China, with special attention to increasing global climate risks.

Summary: This study estimates the willingness to pay of Indian urban consumers for a continuous supply of electricity using contingent valuation method. The findings show that the amount consumers are willing to pay depends on the duration of power outages, with households preferring shorter outages. Income and environmental attitude also positively influence higher willingness to pay. These insights can inform policymakers in designing more reliable and customer-centric energy generation and distribution models.

Summary: The study finds that oil price shocks have a negative impact on Africa's energy transition, particularly in rural areas and net crude oil exporting countries. However, oil price shocks cannot explain the urban-rural differences in clean energy access. Therefore, increasing investment in clean energy and technologies in rural areas is necessary to enhance the resilience of the energy sector to oil price shocks.

Summary: The Renewable Energy Certificate (REC) is considered an innovative technology for building a green society. This study investigates the impact of REC purchases on stock return and volume in Taiwan between 2017 and 2021. The findings suggest that REC purchases have a positive effect on stock returns of manufacturing firms but not service firms. The frequency of REC purchases is also an important factor in the relationship between REC purchase and firm value. Additionally, the study reveals that public attention to environmental pollution plays a crucial role in positive stock returns and volume, while ESG disclosure is negatively associated with returns and volume.

Summary: This paper addresses the challenges of governing energy procurement from a mix of non-hydropower renewable energy sources supplied by independent producers. Building on political economy analysis and five case studies of independent producer projects from Ethiopia, it seeks to understand the root causes of the protracted delays and limited extent of procurement by independent producers. The key contestations lie in managing long term contracts, risk, uncertainty and in developing the institutional and human capacity to transition.
