The deployment of distributed generation in electricity distribution networks can potentially increase their reliability and reduce the cost of power, by installing energy sources closer to the demand or consumption points. This type of generation involves a great variety of energy sources, such as; wind, solar, hydraulic, fossil fuels, biomass, among others.</p> Edison Fabián Sumba Sumba, Angel Victor Sumba Sumba, Guillermo Antonio Loor Castillo, Jesus Alberto Pérez Rodríguez ##submission.copyrightStatement## Thu, 06 Feb 2020 09:09:35 +0000 Potential energy of plant biomass: banana, coconut, cacao and corn <p style="text-align: justify;">In this document, a study was carried out on the energy potential of plant biomass in the Portoviejo canton, since climate change is not a utopia, but the reality. Throughout this study, an overview of the capacity in biomass at the national, provincial and cantonal level (Portoviejo) was presented, a study on the culture of banana, cocoa, coconut, and corn was made since it is important to know if the canton can respond to the biomass demand of the selected plants. Then the socio-economic and environmental impacts were analyzed in a general way.</p> Genial Belvine Epeni Tombo, Edison Cedeño Zambrano, Jair Loor Barreiro, Jordi Medranda Posligua ##submission.copyrightStatement## Tue, 31 Mar 2020 12:38:31 +0000 Obtaining biogas product from biological residues vaccines in Chone city <p style="text-align: justify;">In this research, we studied the use of cattle biological waste to obtain biogas through a biodigester in the city of Chone, considered the livestock capital of Ecuador. Biogas is a mixed gas produced by the fermentation (anaerobic digestion) of organic materials in the absence of oxygen. It is mostly composed of methane and carbon dioxide. The biogas production process takes place in a container called a digester, in which the anaerobic fermentation process occurs. Obtaining biogas is one of the most used alternative sources for the production of renewable energy, so it can be evidenced by its importance as a tool against the fight of the environmental problem that exists today. The use of biogas of bovine origin has a high calorific value so it can be used for the production of heat, electricity or biofuel. This initiative seeks to manage and sustainably reduce organic waste, reduce the amount of greenhouse gas emitted into the atmosphere and reduce dependence on fossil fuels.</p> Janner Leonel Santos Mantuano, Manuel Enrique Vergara Macías, Erik Sebastian Sanchez Toapanta, Klever Steven Tubay Palma, María Fernanda Vivas Giraldo ##submission.copyrightStatement## Wed, 01 Apr 2020 13:30:15 +0000
