Abstract The aviation sector is a major emitter of fossil fuel-derived carbon dioxide contributing to global warming. For instance, jet fuel consumed by the industry 1.5–1.7 billion barrels per year, resulting in 705 million metric tons emissions. Aircraft manufacturers have set ambitious goals, aiming for carbon-free growth post-2020 and 50% reduction greenhouse gas emissions 2030. This issue can be solved replacing fuels with biofuels produced from modern biomass, thus meeting neutral objective. Here, we review technologies convert biomass into biofuel focus on reactants, catalysts, chemistry combustion. Reactants include alcohols, oil, esters, fatty acids, sugars. Catalysts Fischer–Tropsch palladium, platinum, ruthenium, nickel, molybdenum. utilization could potentially reduce up 80%. We also discuss economic implications.

Abstract Pollution and the rising energy demand are two major society issues, requiring urgent solutions. Here, we review simultaneous production of hydrogen removal pollutants, with a focus on mechanisms, synthesis photocatalysts, applications. Remarkably, this method utilizes organic pollutants as sacrificial agents for photocatalytic production, thus both reducing pollution producing energy. Metal-doped, cocatalyst-loaded, inorganic composite, heterostructure heterojunction photocatalysts described. We present applications to antibiotics dyes. Pollutant degradation rates range from 5.3 100%, evolution 13.7–2724.89 μmol·g –1 h .

Abstract In the pursuit of sustainable energy solutions, hydrogen emerges as a promising candidate for decarbonization. The United States has potential to sell wind at record‐low price 2.5 cents/kWh, making production electricity up four times cheaper than natural gas. Hydrogen's appeal stems from its highly exothermic reaction with oxygen, producing only water byproduct. With an content equivalent 2.4 kg methane or 2.8 gasoline per kilogram, boasts superior energy‐to‐weight ratio compared fossil fuels. However, energy‐to‐volume ratio, exemplified by liquid hydrogen's 8.5 MJ.L −1 versus gasoline's 32.6 , presents challenge, requiring larger volume energy. addition, this review employs life cycle assessment (LCA) evaluate full cycle, including production, storage, and utilization. Through examination LCA methodologies principles, underscores importance in measuring environmental sustainability consumption. Key findings reveal diverse pathways, such blue, green, purple hydrogen, offering nuanced understanding their inventories. impact is explored, supported case studies illustrating implications. Comparative analysis across different pathways provides crucial insights decision‐making, shaping considerations. Ultimately, emphasizes LCA's pivotal role guiding economy toward low‐carbon future, positioning versatile carrier significant potential.

Rapid urbanization and population growth have intensified global energy demand, with fossil fuel consumption aggravating air pollution climate change. Hydrogen, a clean carrier, is essential for transitioning to low-carbon economy. This study examines the color-coded classification of hydrogen production pathways, derived from both renewable non-renewable sources, their emission profiles. Additionally, it delves into critical aspects storage transportation, highlighting need robust infrastructure ensure effective integration system. The concludes that traditional methods, such as coal gasification steam methane reforming (SMR), significantly contribute due reliance on fuels lack carbon capture. While blue hydrogen, utilizing capture (CCS), offers reduction in greenhouse gas (GHG) emissions, turquoise green produced via pyrolysis water electrolysis, respectively, present cleaner alternatives zero GHG emissions. With regard storage, metal complex hydrides emerge cost-effective options, while compressed suitable large-scale storage. For applications demanding high density, liquefied cryo-compressed are viable, despite associated costs complexities. pressurized tanks, cryogenic liquid tankers, pipelines considered. Pipelines favored long-distance transportation cost-effectiveness, tankers preferred short distances, higher requirements.
