Abstract

In Asia, Vietnam is one of the countries severely affected by energy shortages and climate change. Development of renewable energy from livestock wastes, e.g., production of electricity from biogas, is a solution for reducing greenhouse gas emissions and pollution from untreated livestock wastes, as well as energy shortages. So that, biogas technology has been researched and applied in Vietnam since the 1960s. The development and state-of-art issue of household biogas, specifically, the opportunities and constraints of household biogas are presented in this paper. There are several opportunities for household biogas development, including, the availability of biogas fermentation materials, energy shortage issues, and policy support from the Government of Vietnam and international organizations. Besides, barriers encountered in household biogas development in Vietnam included technical barriers, financial policy barriers, awareness and capacity limitations. The capacity building should include the dissemination and update of policy to maintain transparency and credibility for attracting potential domestic investors. Training courses should be provided to technical staff of biogas digester on operation and maintenance. Measures should be taken to improve the policy and mechanisms, especially, financial mechanisms.
