Office of Electricity and Energy Innovation came up with a “Managing Biogas Manufacturing System” Project for use with Khon Kaen University’s vehicles and machinery so that the use of energy is worthwhile and most efficient. This will lead to the university’s being the prototype of sustainable energy conservation and a major mechanism behind energy conservation success. In addition, the system is a research and innovation resource for the production process and utilization of biogas. Moreover, the project supports the policy of Green University & Smart Campus, with personnel’s understanding and having skills for using energy for utmost benefits and supporting the government’s policy.  


          On March 9, 2017, at the Compressed Biomethane Gas (CBG) Station, Faculty of Agriculture; Office of Electricity and Energy Innovation held a debut for the use of biogas fuel manufactured from animal wastes in cars. Asst. Prof. Dr. Panomchai Weerayutsin, Vice President for Infrastructures; Asst. Prof. Kritpat Thapalabut, Assistant to the President for Infrastructures; Asst. Prof. Dr. Somsak Pitaksanurat Director of Environmental and Hygiene Office; Mr. Pitoon Moonsri, Head of Maintenance and Special Operation Work; Mr. Watchara Patanawiwat porn, Director of Division of Buildings and Areas; Mr. Chainiyom Sintorn, Mechanical Machine Trainer; Mr. Mongkon Puinoi, Head of Innovation and Energy Management Work; Asst. Prof. Dr. Chatchai Benjapiyaporn, Director of Energy Management and Conservation Office (EMCO) were honorary guests. The CBG  is produced from animal wastes and Napier grass.

          Mr. Chainiyom Sintorn, Mechanical Machine Trainer and Secretary of the Project said, “This renewable energy of biogas from animal wastes can be used to fill in gasoline or benzene hybrid cars. Some cars at the President Office use NGV, and so they can be filled in with CBG without having to be adjusted. Today, we filled in 4 cars with CBG. These cars belong to Environmental and Hygiene Office and Maintenance and Special Operation Work, Division of Buildings and Areas. There is a plan to use this biogas fuel for pumping treated wastewater to the grazing grass of Faculty of Agriculture and for watering plants in the Yang-Na wood at Srithan. The biogas fuel will also be used to operate sprinklers in the farm, electricity generators, biodiesel distiller and Yang-Na oil distiller. Office of Electricity and Energy Innovation itself will open this production as an efficient learning resource to disseminate knowledge of energy management among relevant organizations, communities, and people in general as a model organization that care for the environment.”


Asst. Prof. Dr. Chatchai Benjapiyaporn, Director of Energy Management and Conservation Office (EMCO) said, “CBG Station, KKU or Compressed Biomethane Gas Station, Khon Kaen University is the station that produces biogas through the cleaning or removing of unclean gases, i.e., Hydrogen sulfide and carbon dioxide. The amount of gas can be measured from digital values. For instance one baht equals 2 kilos. At present the station cannot produce quite a big amount of biogas, i.e., about 200 ft3 of fermented biogas can be produced into 100 kg for 10 cars, which is not enough. The production will remain unchanged for these 3 years since the methane gas source, hen and pig pens do not yield sufficient gas. If in the future, these animal farms are expanded, more gas may be available.”


          Asst. Prof. Dr. Chatcha added, “The gas produced at the station meets the standard of the Department of Energy Business, Ministry of Energy. The problematic gas or hydrogen sulfide should not exceed 15 ppm. The station invented an element to get rid of this gas and therefore it only measures 0.9 ppm, comparable to NGV at stations in general. The only difference is the business stations contain methane gas from drilling, but it is from fermentation at our station. Hydrogen sulfide at the station is 0.2 ppm from 200 ppm. This means the gas is clean.”


The “Managing Biogas Manufacturing System” Project is under the responsibility of Office of Electricity and Energy Innovation, Khon Kaen University. The project was implemented in order to be a prototype for managing biogas system for the benefits of study, research, system and process development and management of sustainable database. The office is the supporting organization for planning the use of biogas in governmental and private organizations, which will be the learning resource.
