Abstract

This paper presents an overview of research related to the production, storage and application of Biogas currently in VietNam and the world. The application of technology to refine and improve quality to meet the use of biogas in internal combustion engines is presented. The characteristics of economic, technique and environmental of four different kinds fuel supply system using biogas on combustion engine are analyzed to meet the advantages and disadvantages of each type and feasibility of practical application use of biogas combustion engine. The modern technology in refining biogas for use in fuel cells and on public transport (bus, taxi) are introduced and researched.
