- Rice husk is a residue from rice, which is grown in large quantities in Vietnam. By using rice husk as a fuel for heat andpower production, dual environmental benefits can be achieved. Since it is a carbon neutral fuel, it can be a way ofoffsetting carbon dioxide emissions from energy supply systems. The use of rice husk for energy purposes can also helpsolve disposal problems at locations where husk is dumped in rivers or burnt in open piles. The aim of this study is toinvestigate whether rice husk can be used in an economical way to meet the energy demand within the rice millingindustry, mainly electricity, and/or to produce electricity for sales to the national grid. Different energy conversiontechnologies are considered for three sizes of power plants, suitable to meet different demand categories, and their respective lifetime costs of generation are calculated. The impacts on project economy of the Clean Development Mechanism, rice husk ash sales and cogeneration of heat are also investigated. The lifetime costs of generation of the different power plants are compared with the electricity price in Vietnam. The results show that the profitability is influenced by whether the electricity is sold directly to rice mills or to the national grid. For large plants, economic viability can be reached without revenues from ash sales or the CDM. For smaller plants either of them is required.

- This paper focuses on energy system development of the three largest ASEAN (Association of South East Asian Nations) countries; Indonesia, Philippines and Vietnam. The energy infrastructures in these counties are in the process of rapid development and, therefore, technology choices are critical. Applying the energy system model MARKAL and scenario analysis, this paper examines and quantifies the role of clean and advanced energy technologies for efficient local resource exploitation and improving energy security and environmental conditions. The main focus is on the power sector and the paper also addresses the potential ASEAN markets for European energy technologies. The paper concludes that there is a large potential market for clean and advanced energy technologies in the studied countries. If adopted, these technologies will bring several benefits like reduction in primary energy requirement, reduced investments requirement in the power sector and other parts of the energy infrastructure, reduced import of primary energy, reduced CO2 emissions and local pollution, reduced energy system costs and marginal cost of electricity supply. Finally, barriers for transfer and diffusion of advanced energy technologies are discussed.
