Sustainability Assessment of Aviation Fuel Blends&nbsp;Cherie Nicola Gambino &amp; T. Agami ReddySchool of Sustainable Engineering and the Built EnvironmentArizona State University, Tempe AZThe aviation industry is comprised of civilian flyers, commercial transport, freight transport, and military operations. In 2009 these&nbsp;&nbsp;stakeholders&nbsp;&nbsp;committed to a goal of 50% reduction in&nbsp;&nbsp;carbon emissions by the year 2050, by reducing emissions by 1.5% each year from 2020 onwards. There are multiple pathways to achieve this goal however; the most promising are one class of fuels, called Sustainable Aviation Fuels (SAF) which are biofuels blended with traditional kerosene jet fuel. As the industry shifts to mass consumption of SAF, it is important to evaluate these fuels in terms of their long-term sustainability. A Multi Criterion Decision Making methodology along the lines of the Modelo Integrado de Valor para Estructuras Sostenibles (MIVES) method is adopted. This approach considers&nbsp;&nbsp;environmental, economic, and social requirements based on&nbsp;&nbsp;lower level criteria represented by&nbsp;&nbsp;indicators. These indicators are first normalized&nbsp;appropriately, then multiplied by their relative importance, and aggregated to form a criterion-level value. The second stage involves a set of similar steps for each criterion to determine a final sustainability score. A Monte Carlo analysis was performed for added sensitivity by varying&nbsp;&nbsp;the relative importance of the three criteria. In total, sixteen (16) aviation fuels have been&nbsp;&nbsp;assessed&nbsp;&nbsp;which include fossil, natural gas, electric, and SAF in order to ensure a valid and representative cross section of possible fuels. The criteria by which the fuels were assessed were ecological footprints, cost of transportation, investment cost, operating costs, employment generation, and health and safety. Of the fuels assessed, the most sustainable was found&nbsp;&nbsp;to be Hydrogen, with a normalized score of 0.91 out of 1.0. The least sustainable fuels were determined to be the military kerosene-based fuels (with the experimental fuel JP-8 + 100LT being the poorest with a normalized score of 0.50).&nbsp;

ASME 2021 Energy Sustainability (ES2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
