Optimization Study of the Sustainable-Energy Grid Based on the Zero Emission Technology (2003.4-2013.3)
The study project “Optimization Study of the Sustainable-Energy Grid Based on the Zero Emission Technology” was adopted for the project of private university support conducted by the Ministry of Education, Culture, Sports, Science and Technology in Japan. The perpose of this project is to become a main base for the study of the sustainable-energy and zero emission technique based on the research products obtained from the “Academic Frontier” Project, Next-generation Zero Emission Energy Conversion System, and the projects with international-communication. In particular, it is purpose to construct the sustaibable-energy grid based on the holonic control with promoting the studies for each energy conversion devices such as fuel cell, co-generation system, energy reserve unit and so on.
"Academic Frontier" Next Generation Zero Emisson Energy Conversion System (2003.4-2007.3)
Joint research project "Next generation zero emission energy conversion system" (The project leader: Prof. H. Fujimoto, Faculty of Engineering) was adopted, which has a background of "Academic frontier promotion work" of academic research promotion work in private university in 2003, by the Ministry of Education, Culture, Sports, Science and Technology. The research project startrs since April of 2003. In order to carry out the Academic frontier joint research project, Research Center for Energy Conversion System was arranged as a research base in Office for Research Initiative and Development, Doshisha University. The objective of this project is to study the most suitable energy conversion process for environmental preservation. Based on the objective, all the fundamental researchs are conducted regarding energy conversion systems for automobile, industrial, domestic use etc. In addition, hybrid system of the gas engine cogeneration and the CO2 heat pump is set up as a large-scale research apparatus in this project. The investigations related to low-pollution and high-efficiency utilization of the cogeneration of heat and power are carried out.
Co-Generation System ・The gas engine co-generation system using natural gas that is cleam emergy (emissions of CO2 and NOx are a little, and SOx is hardly produced) has been introduced.
The high temperature water is recovered from the exhaust heat (exhaust gas & jacket water) of gas engine, and it is used for air-conditioning in Energy Conversion Research Center.
