This study explored the role of airports in aviation sector from both energy and sustainability perspectives, highlighting their potential contribution to reducing sector’s carbon emissions. The methodology involved a literature review questionnaire distributed organizations. results these approaches indicated varying focuses on tackling subject. clear preference papers for SAF solutions over development more environmentally friendly airports. Adoption 100% aircraft is still its early stages can be considered long-term goal because it requires heavy engineering intervention alteration engines. transition airports’ infrastructures, other hand, visualized as feasible attainable hence should short-term attain. Many airports, including respondents questionnaire, have already worked infrastructure; however, they also expressed concerns about lack enabling policies incentives. Other action steps, such close collaborations among stakeholders, enhancing research development, government support, were seen significant establishing greener indicate major gap integral part (i.e., airports). It therefore important that member states collaborate work closely with key organizations ICAO, IATA, UN through latter’s Sustainable Development Goals (SDGs) breach this establish sustainable near future.

The current study focuses on the theoretical assessment of Sustainable Aviation Fuels (SAFs) obtained by blending traditional jet fuel (Jet A) and different liquids (biodiesel alcohols) from an analytical point view. Aeroshell 500 oil was added (5% vol.) to ensure lubrication turbo engine. An in-depth analysis physical-chemical properties Jet A blended with biodiesels alcohols performed. considered blends consisted biodiesel palm oil, pork fat, sunflower methanol, ethanol, butanol. All six were mixed 10, 20 30%. Flash point, kinematic viscosity, density, freezing elemental analysis, FTIR conducted for all blends. acquired results show influence each component Based blends, conclusions latter’s behavior during burning drawn gaseous pollutants resulting process examined.

A novel integrated gas-cooled fast nuclear reactor and vanadium chloride thermochemical cycle for sustainable fuel production

Journal of Cleaner Production, Год журнала: 2024, Номер 468, С. 142853 - 142853

Опубликована: Июнь 12, 2024

The continuous growth of anthropogenic carbon emissions from the aviation industry has emphasized urgent request to substitute traditional fuels with Sustainable Aviation Fuels (SAFs) because SAFs can potentially reduce by around 50-90% as compared kerosene-based fuels. In this paper, a novel SAF production pathway been developed which is based on biomass processing, nuclear energy, and thermochemical reactions vanadium chloride cycle for SAF, clean power, hydrogen production. entire system assessed thermodynamically in terms energy exergy performances. Various sensitivity analyses are computed determine reliable operating parameters. study concludes that biomass-to-SAF energetic exergetic performance was achieved be approximately 76.72% 74.35%. values, through efficiencies, V-Cl were calculated 68.08% 53.50%, respectively. For storage, an penalty 16.83 kJ/kg H2 calculated, results efficiency 6.18%. overall efficiencies proposed integrated found 59.79% 23.78%,

Fuelling a Clean Future: A Systematic Review of Techno-Economic and Life Cycle Assessments in E-Fuel Development

Applied Sciences, Год журнала: 2024, Номер 14(16), С. 7321 - 7321

Опубликована: Авг. 20, 2024

The transition to sustainable energy has ushered in the era of electrofuels (e-fuels), which are synthesised using electricity from renewable sources, water, and CO2 as a alternative fossil fuels. This paper presents systematic review techno-economic (TEA) life cycle assessments (LCAs) e-fuel production. We critically evaluate advancements production technologies, economic feasibility, environmental implications, potential societal impacts. Our findings indicate that while e-fuels offer promising solution reduce carbon emissions, their viability depends on optimising processes reducing input material costs. LCA highlights necessity for hydrogen ensure genuine sustainability e-fuels. also identifies knowledge gaps, suggesting areas future research policy intervention. As world moves toward greener future, understanding holistic implications becomes paramount. aims provide comprehensive overview guide stakeholders decision-making processes.

In Situ Hydrogenation of Methyl Palmitate to Hexadecanol on TiO₂- and ZrO₂-Supported Ni–In Catalysts in the Aqueous Phase Using Methanol as a Hydrogen Donor

Energy & Fuels, Год журнала: 2024, Номер 38(21), С. 21232 - 21244

Опубликована: Окт. 21, 2024

Selective hydrogenation of fatty acids/esters is an efficient way to produce alcohols, and it very promising provide in situ H2 generated via aqueous phase reforming hydrogen donors. Here, the supported Ni–In intermetallic compounds (IMCs) were prepared for methyl palmitate hexadecanol using methanol as a donor. First, effects Ni/In atomic ratio metal loading on performance ZrO2-supported IMCs investigated. Different from metallic Ni that favors decarbonylation/decarboxylation generating n-pentadecane, all Ni2In, NiIn, Ni2In3 facilitate selective yield hexadecanol. Therein, NiIn IMC with total 40 wt % gives best 87.6%. Second, different supports [ZrO2, TiO2, Al2O3, SiO2, activated carbon (AC)] was compared. ZrO2- TiO2-supported (especially TiO2) show higher stability than others. This ascribed their hydrothermal interaction IMC, restraining sintering leaching IMC. During four times recycling, maintains ∼80% while slightly decreases 87.6% ∼83% slight deactivation which due deposition. In contrast, Al2O3 converted boehmite under condition, there remarkable species SiO2 AC, are detrimental catalyst stability.
