This paper provides a comprehensive overview of the physical properties and applications natural gas (NG) hydrogen as fuels in internal combustion (IC) engines. The also meticulously examines use both NG fuel vehicles, their production, characteristics, properties. It reviews current experimental studies literature investigates results using fuels. further covers challenges associated with injectors, needle valves, lubrication, spark plugs, safety requirements for Finally, related to storage, are discussed. review reveals that ignition (SI) engines has clear direct positive impact on economy certain emissions, notably reducing CO2 non-methane hydrocarbons. However, its effect other such unburnt hydrocarbons (UHC), nitrogen oxides (NOx), carbon monoxide (CO), is less clear. NG, which primarily methane, lower carbon-to-hydrogen ratio than diesel fuel, resulting emissions per unit energy released. In contrast, particularly well-suited gasoline due high self-ignition temperature. While increasing content reduces torque power output, higher input reduced consumption mitigation toxic exhaust emissions. Due temperature, not inherently suitable engines, necessitating exploration alternative methods introduction into cylinder. suggests shown reduction specific an increase NOx Overall, valuable informative opportunities IC highlights need research development address remaining challenges, more efficient chambers

Green hydrogen from electrolysis of water has attracted widespread attention as a renewable power source. Among several production methods, it become the most promising technology. However, there is no large-scale system currently that can compete with conventional fossil fuel production. Renewable energy electrocatalytic splitting an ideal technology environmental cleanliness protection and good purity, which meet requirements future development. This review summarizes introduces current status by three aspects: electricity, catalyst electrolyte. In particular, present situation latest progress key sources power, catalytic materials electrolyzers for are introduced. Finally, problems generation electrolytic directions next-generation green in discussed outlooked. It expected this will have important impact on field water.

Rapid industrialization and development have led to a tremendous increase in the use of various types plastic commodities daily life. For past several years, pollution has become global issue, posing serious threat mankind. The primary issue with increasing is lack proper management which created huge havoc environment. From initial phase waste management, been discarded, recycled, downcycled, or dumped into landfills large proportion, causing extreme damage ecosystem. Conventionally, treated via thermal processes such as pyrolysis incineration plants require amount capital and, therefore, harms aim circular economy. Chemical upcycling gaining attention high-potential catalytic strategy convert plastics, polyethylene terephthalate, polyethylene, polystyrene, etc. fuels, functionalized polymers, other value-added chemicals having direct impact on affordability viability. In this review, we focused photocatalysis, electrocatalysis, photoelectrocatalysis effective efficient technologies. These approaches can lower dependence nonrenewable resources are more environmentally friendly contrast conventional approaches. This review elaborately discusses pros cons provides detailed overview potential renewable energy-driven for conversion wastes valuable fuels commodity chemicals, along challenges future directions emerging approach treatment.

Abstract The technique of producing hydrogen by utilizing green and renewable energy sources is called production. Therefore, implementing this technique, will become a sustainable clean source lowering greenhouse gas emissions reducing our reliance on fossil fuels. key benefit that no harmful pollutants or gases are directly released throughout the process. Hence, to guarantee all environmental advantages, it crucial consider entire supply chain, involving storage, transportation end users. Hydrogen promising targets plan pathways towards decarbonization net-zero 2050. This paper has highlighted techniques for generating needed environment solutions. Moreover, summarizes an overview, outlook transient Consequently, its perspective provides new insights research directions in order accelerate development identify potential

Under the background of power system profoundly reforming, hydrogen energy from renewable energy, as an important carrier for constructing a clean, low-carbon, safe and efficient system, is necessary way to realize objectives carbon peaking neutrality. As strategic source, plays significant role in accelerating clean transition promoting energy. However, cost technology are two main constraints green development. Herein, technological development status economy whole industrial chain “production-storage-transportation-use” discussed reviewed. After analysis, electricity price equipment key factors limiting alkaline proton exchange membrane production technology; quantity, scale distance transportation controlling costs storage transportation. The application mainly concentrated traditional industries. With gradual upgrading progress top-level design technology, including traffic transportation, engineering, storage, gas microgrid will show diversified trend. And bottleneck problems trends industry also summarized viewed.
