Summary: This study presents a robust route optimization model for electric Demand-Responsive Transit (e-DRT) services, incorporating online partial charging strategies and flexible service schedules. A two-phase Adaptive Large Neighborhood Search (ALNS) heuristic is proposed to effectively solve the optimization problem. Experimental results demonstrate the effectiveness and accuracy of the proposed method, with the proposed algorithm significantly improving computational efficiency compared to CPLEX. Furthermore, a comparative analysis shows that the proposed model reduces total cost by 21% compared to a non-robust alternative model. Two sensitivity tests reveal the impacts of unmet real-time requests and charging rate on the performance of the e-DRT system.

Summary: This paper builds a one-way electric carsharing model and integrates it into an open-source multi-agent transport simulation platform (MATSim) to study its supply and demand relationship. A Shanghai baseline scenario was used to validate the model and test the impacts of vehicle range, charging rate, and power supply mode on carsharing demand. The results show that vehicle range and charging rate have minimal impact on carsharing demand, and switching to battery swapping for power supply slightly decreases carsharing usage while trip characteristics remain the same.

Summary: The performance of door-to-door on-demand shared transportation services depends on the operational scheme selected, with economies of scale present when trip rejections are allowed and vehicle automation can reduce operator costs. However, the ability to reject customers goes against the spirit of truly public transportation service.

Summary: China has made notable progress in decarbonizing its transportation sector, specifically in vehicle electrification. However, the economically effective pathways to achieve carbon neutrality still need further exploration. This study examines twenty decarbonization pathways and finds that achieving the 2060 zero-greenhouse gas emission goal for light-duty vehicles is possible through electrification if the battery pack cost remains below CNY483/kWh by 2050. However, under pessimistic battery cost scenarios, additional internal subsidies of CNY8.86 trillion are required to ensure over 80% market penetration of battery electric vehicles in 2050, resulting in a reduction of 246 million tonnes of CO2-eq emissions by 2050.

Summary: The heating sector in the European Union plays a crucial role in the energy transition, and district heating is a promising solution for reducing environmental impact. Excess heat from various sources has the potential to contribute to district heating, but a deregulated heat market is needed. This study examines the feasibility of different bidding strategies on the heat market and finds that supplying low temperature excess heat to high temperature district heating networks is not feasible. Lower temperature district heating is necessary for the utilization of low temperature excess heat. The analysis also shows that power market prices have a significant impact on the feasibility of low temperature excess heat, indicating that increasing the share of renewables in the power market could facilitate the utilization of these heat sources.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
