With the large-scale deployment of renewable energy the issue of wind power consumption has become increasingly prominent leading to serious wind energy abandonment. In order to promote energy sustainability this paper proposes a low-carbon economic scheduling model of an integrated energy system (IES) that combines the flexible supply–demand response with the diversified utilization of hydrogen energy. A mixedinteger linear progra Read More

This work aims to study the technical and economical feasibility of a new hydrogen transport network by 2035 in France. The goal is to furnish charging stations for fuel cell electrical vehicles with hydrogen produced by electrolysis of water using low-carbon energy. Contrary to previous research works on hydrogen transport for road transport we assume a more realistic assumption of the demand side: we assume that only drivers driving more than Read More

This article summarizes current research on the life cycle assessment (LCA) of fuel cell electric vehicles (FCEVs) in road transport. Increasing greenhouse gas emissions and climate change are pushing the transport sector to intensify efforts toward decarbonization. One promising solution is the adoption of hydrogen technologies whose development is supported by European Union regulations such as the “Fit for 55” package. FCEVs are characterized Read More

The combustion of pure H2 in engines is still troublesome needing further research and development. Using H2 and diesel in a dual-fuel compression ignition engine appears as a more feasible approach. Here we report an experimental assessment of performance and emissions for a single-cylinder four-stroke air-cooled compression ignition engine operating with neat diesel and H2-diesel dual-fuel. Previous studies typically show the performance and emissi Read More

One of the primary contributors to automobile exhaust pollution is the significant deviation be tween the actual and theoretical air-fuel ratios during transient conditions leading to a decrease in the conversion efficiency of three-way catalytic converters. Therefore it becomes imperative to enhance fuel economy reduce pollutant emissions and improve the accuracy of transient control over air-fuel ratio (AFR) in order to mitigate automobile exhaust pollutio Read More

Hydrogen is regarded as a viable alternative energy carrier because of its superior energy density and low emissions with great potential for decarbonizing multiple sectors and improving energy sustainability by integrating into the existing energy systems and renewable energy source within the utility. This paper provides a bibliometric assessment through an extensive review of highly cited articles on hydrogen storage integrated microgrid. The study utiliz Read More

Electric bus transit is crucial in reducing greenhouse gas (GHG) emissions decreasing fossil fuel reliance and combating climate change. However the transition to electric-powered buses demands a comprehensive plan for optimal resource allocation technology choice infrastructure deployment and component sizing. This study develops system configuration optimization models for battery electric buses (BEBs) and hydrogen fuel cell buses (H Read More

Hydrogen injection (HI) is an emerging decarbonisation technology for ironmaking blast furnaces (BFs) yet its impact on the in-furnace phenomenon in the raceway of an industry BF remains unclear. In this study an industrialscale Reactive Computational Fluid Dynamic Discrete Element Method coupling model (rCFD-DEM) is developed to study the impacts of HI on the raceway dynamics and coke combustion inside an industrial-scale BF. To overcome the l Read More

The utilization of “green” hydrogen in transportation areas gives rise to production- and supply infrastructure-related challenges; therefore its wider application in automotive transport would lead to higher demand with cost reduction and a faster expansion of the hydrogen refuelling network. This study presents energy and environmental performance indicators analyses of a Nissan Qashqai J10 engine during the Worldwide Harmonised Light Vehi Read More

To reduce hydrogen consumption by hydrogen fuel cell vehicles (HFCVs) an adaptive power-following control strategy based on gated recurrent unit (GRU) neural network operating condition recognition was proposed. The future vehicle speed was predicted based on a GRU neural network and a driving cycle condition recognition model was established based on k-means cluster analysis. By predicting the speed over a specific time horizon feature para Read More
