“…Al respecto, primero se precisaron las investigaciones hechas bajo la modalidad de tesis de grado de licenciatura, obteniendo un total de 7 en el lapso 2010-2014, Tabla 8. Es resaltable que en 5 de ellas se estudia la producción de H 2 por electró-lisis con vista a su utilización en mezclas combustibles para motores de combustión interna, aplicación bastante debatida y controversial en cuanto a su soporte teórico, viabilidad técnica y seguridad operativa [53][54][55].…”

The hydrogen economy, H2, is an emerging energy paradigm proposed to H2 as the vector that drives the development of human society in this century, and as embodied in the energy system Solar Hydrogen SESH where primary sources are renewable, and it is the secondary source H2. A large number of countries are undertaking plans to incorporate the SESH in their energy structure. In this context, this paper argues whose purpose is to identify and analyze the factors involved in the development of SESH in Ecuador, through research supported methodologically on a literature review and a survey of a group of experts involved, from different fields, renewable energy and the H2 as a vector. It is obtained that the country has sufficient potential exploitable renewable energy to ensure the operability of SESH, with hydropower and biomass are the most appropriate sources. Furthermore, the vision of development of the Ecuadorian state, driving the transformation of the energy matrix by the massive incorporation of renewable energy, would favor the gradual penetration SESH, especially in two niche opportunities, rural electrification and urban transport. Barriers are also reported: scarce and scattered research activity; minimum formation of human talent necessary for the operation and innovation in the technologies of H2; absence of a legal and regulatory framework that encourages penetration SESH and the incipient formation of collaborative networks in research and advocacy, in the balance predominate advantages over the barriers. It is concluded that only by agreed action academia, research centers and private companies, under the tutelage of the state will allow this new energy system contributes to sustainable development and conductive Ecuador joining hydrogen economy.Keywords.

ResumenLa economía del hidrógeno, H2, es un paradigma energético emergente que propone al H2 como el vector que conduzca el desarrollo de la sociedad humana en este siglo, y que se concreta en el sistema energético Solar Hidrógeno, SESH, en el cual las fuentes primarias son renovables y la fuente secundaria es el H2. Una amplia cantidad de países están emprendiendo planes para la incorporación del SESH en su estructura energética. En este contexto se plantea este artículo cuyo propósito es identificar y analizar los factores intervinientes en el desarrollo del SESH en el Ecuador, mediante una investigación soportada metodológicamente en una encuesta aplicada a un conjunto de expertos involucrados, desde diferentes ámbitos, con las energías renovables y con el H2 como vector, y en una revisión documental. Se obtiene que el país dispone de suficientes potenciales aprovechables de energías renovables para garantizar la operatividad del SESH, siendo la hidroenergía y la biomasa las fuentes más adecuadas. Además, la visión del desarrollo del Estado ecuatoriano, impulsando la transformación de la matriz energética mediante la incorporación masiva de las energías renovables, favorecería...

“…Musmar [19] y Al-Rousan [20] diseñaron dispositivos capaces de generar HHO para motores a gasolina. Los autores mostraron que los porcentajes de emisión de contaminantes se reducían hasta en un 50% de óxidos de nitrógeno, 20% de monóxido de carbono y el gasto de combustible en un 30 % al ser agregado a la mezcla de combustión gas HHO.…”

RESUMENLos motores de combustión interna a gasolina tienen conocidos problemas de eficiencia térmica y alto índice de emisión de gases contaminantes. Por otro lado, existen procesos químicos y eléctricos que han permitido obtener fuentes de energía limpia del agua. La electrólisis permite mediante un proceso electroquímico la obtención de gas de hidrógeno y oxígeno, de cuya mezcla se obtiene HHO. Las características moleculares del HHO permiten la disminución de gases tóxicos al ambiente y el ahorro de combustibles hidrocarbonados en motores de combustión interna. En este trabajo se investigan los beneficios potenciales de la mezcla de HHO como aditivo a los combustibles fósiles, en particular, la gasolina comercial. Se describe el diseño de un sistema con una celda electrolítica y se evalúa el desempeño de un motor de 110 cm 3 en términos del consumo específico de combustible, potencia, torque y emisión de gases.PALABRAS CLAVE: electrólisis; celdas de oxihidrógeno; motores de combustión interna; energía limpia; combustibles. ABSTRACTGasoline internal combustion engines have known issues related to thermal efficiency and high emission of polluting gases. On the other hand, there are chemical and electrical processes that have provided sources of clean energy from water. Electrolysis allows the production of hydrogen and oxygen gas by means of an electrochemical process, from which HHO is obtained. The molecular characteristics of HHO allow the reduction of toxic gases to the environment and the saving of hydrocarbon fuels in internal combustion engines. In this paper, we investigate the potential benefits of HHO mixtures as an additive to fossil fuels, in particular, commercial gasoline. We describe the design of a system with an electrolytic cell and evaluate the performance of a 110 cm 3 engine in terms of brake specific fuel consumption, brake power, brake torque and gas emissions.

Control Scheme Formulation for the Production of Hydrogen on Demand to Feed an Internal Combustion Engine

et al. 2016

Abstract:In this work, a control strategy is presented to produce hydrogen on demand to feed an internal combustion (IC) engine. For this purpose, the modeling of the IC engine fueled by gasoline blended with 10% v/v of anhydrous ethanol (E10) and hydrogen as an additive is developed. It is considered that the hydrogen gas is produced according to the IC engine demand, and that the hydrogen gas is obtained by an alkaline electrolyzer. The gasoline-ethanol blend added into the combustion chamber is determined according to the stoichiometric ratio and the production of hydrogen gas is regulated by a proportional and integral controller (P.I.). The controller reference is varying according to the mass flow air induced into the cylinder, in order to ensure an adequate production of hydrogen gas for any operating condition of the IC engine. The main contribution of this work is the control scheme developed, through simulation, in order to produce hydrogen on demand for any operating point of an internal combustion engine fueled by an E10 blend. The simulation results showed that the use of hydrogen gas as an additive in an E10 blend decreases the E10 fuel consumption 23% on average, and the thermal efficiency is increased approximately 2.13%, without brake power loss in the IC engine.
