Published: May 30, 2024

This comprehensive review examines the role of sustainable aviation fuels (SAFs) in promoting a more environmentally responsible industry. study explores various types biofuels, including hydroprocessed esters and fatty acids (HEFAs), Fischer–Tropsch (FT) fuels, alcohol-to-jet (ATJ) oil derived from algae. Technological advancements production processing have enabled SAF to offer significant reductions greenhouse gas emissions other pollutants, contributing cleaner environment better air quality. The addresses environmental, economic, technical benefits SAF, as well challenges associated with their adoption. Lifecycle analyses are used assess net environmental focus on feedstock sustainability, energy efficiency, potential impacts biodiversity land use. Challenges such economic viability, scalability, regulatory compliance discussed, emphasis need for supportive policies international collaboration ensure long-term sustainability SAF. also current applications commercial airlines military settings, highlighting successful case studies regional differences driven by policy frameworks government incentives. By technological innovation addressing barriers, has play crucial industry’s transition toward sustainability.

This paper investigates the techno-economic implications on air travel when fossil-based kerosene is phased out of market, specifically focusing comparison between liquid hydrogen, methane and renewable for ten exemplary flight routes to estimate cost per passenger 100 km distance travelled €2020PAX100km every fuel type. By considering entire supply chain, including hydrogen production from sources, synthesis, oversea transport, domestic distribution, utilization, this study addresses overarching question whether it more economical change source or itself reduce fossil usage in aviation industry. It demonstrated that aircraft acquisition costs play a minor role compared specific demand. The shows electricity-based fuels, most economic option, even with potential energy penalty, followed by kerosene. results an capacity 180 passengers are 3.08, 4.57 5.11 €PAX100km kerosene, respectively. Challenges regarding storage isolation requirements cryogenic fuels discussed, assumptions made these obstacles can be overcome realize benefits.

Portrait of the Decarbonization and Renewables Penetration in Oman’s Energy Mix, Motivated by Oman’s National Green Hydrogen Plan

Energies, Journal Year: 2024, Volume and Issue: 17(19), P. 4769 - 4769

Published: Sept. 24, 2024

The aim of this study is to quantitatively describe the anticipated change in energy mix Sultanate Oman (Oman) as country moves forward its national plan for green hydrogen, order become a global producer and exporter. This achieved by curating recent data about projects that are either operating or planned (in construction pre-construction stage). Then, these processed further extract useful insights how would if realized added ones. reveals serious commitment accomplish hydrogen (GH), where production ambition 2030 1.125 million tons per annum (Mtpa), using renewable capacity approximately 18 GW. increases 3.5 Mtpa with 70 GW renewables 2040, 8 180 2050. As portrait Oman’s assumption successfully completing all projects, we found expected have total 83.1271 GW, share (solar wind) reaching 83.133% (as compared 15.0711 an 8.907% projects). Nearly (precisely 99.571%) 68.0560 additions based on solar wind energy, while traditional oil–gas gradually phased out. Green dominates surge penetration within Omani mix, 84.659% 34.3140 linked production, water electrolyzers. Similarly, 98.804% 33.4500 production.

Published: March 10, 2025

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.
