Combined Effect of Cetane Improver, Aluminum Oxide Nanoparticles, and Waste Cooking Oil Biodiesel Blend on a Dual Fuel Combustion Engine Run With Biogas Originated From Food Waste

open access: yesEnergy Science &Engineering, Volume 14, Issue 3, Page 1372-1386, March 2026.
Sugarcane juice is clarified and fermented with yeast to produce ethanol and CO₂. The broth is refined through distillation and molecular sieves, yielding fuel‐grade ethanol stored for transport. Bagasse, vinasse, and residues are recycled as valuable by‐products, enabling a sustainable bioethanol production pathway ABSTRACT This study investigates the

Advanced Thermodynamic Analysis and Evaluation of a Supercritical Power Plant

open access: yesEnergies, 2012
A conventional exergy analysis can highlight the main components having high thermodynamic inefficiencies, but cannot consider the interactions among components or the true potential for the improvement of each component.

Exergy sustainability. [PDF]

open access: yes, 2006
Exergy is the elixir of life. Exergy is that portion of energy available to do work. Elixir is defined as a substance held capable of prolonging life indefinitely, which implies sustainability of life. In terms of mathematics and engineering, exergy sustainability is defined as the continuous compensation of irreversible entropy production in an open ...

Exergy and cumulative exergy use analysis

open access: yes, 2016
Exergy is a thermodynamic metric that represents the amount of useful energy one can obtain out of an object in a given reference environment. The exergy concept is used in several applications: from the analysis of industrial processes to economic, sustainability and ecosystem analysis.
