Biofuels in the Greater Mekong Subregion

Abstract In the Greater Mekong Subregion (GMS), a growing demand for biofuels could help support the agriculture sector and provide an alternative source of energy. However, if deployed unsustainably, biofuels development can be associated with numerous risks that have negative ramifications for human development. This paper reviews existing literature and integrates various themes to provide an overview of four main issues related to biofuels deployment in the GMS: the need for alternative energy, risks to food security, considerations for environmental management, and opportunities for rural development. This paper was prepared as a discussion piece for the GMS 2020 International Conference (20–21 February 2012 in Bangkok, Thailand).

Consultation on Biomass Power Generation Technology Improvement

Abstract Biomass resources are very abundant in China, with great energy potential. Energy utilization from biomass is an important way to national economic sustainable development on renewable energy, as well as reducing pollution to environment. Renewable Energy Law has been legislated in February 2005 in China, in which the development and utilization of renewable energy ranks priority item among Chinese energy development. CRESP cooperated between the State Development and Reform Commission of China and the World Bank aims at expanding and developing China’s renewable energy utilization to accelerate technological scale-up and industrialization process. CRESP office has entrusted and supported Guangzhou Institute of Energy Conversion (GIEC), CAS to make an elaborate analysis and assessment of cogency on the application of biomass electricity generation technology in China, which constitutes part 1 of this report, and is submitted to the Expert Workshop on “Analysis of Potential in China for Improvement in Biomass Power Generation Technology” of CRESP in April 2005. Based on the analysis and assessment, Experts and researchers participating in the conference discussed and expressed various opinions on some important points such as foreign and domestic relevant technologies and future development trend, biomass energy technological industrialization and which technologies are priority of industrial support and special measures. Everyone has the consensus that energetically developing biomass power generation technology is of importance to national sustainable development, particular to the wide rural and remote areas in China. The meeting summary constitutes part 2 of this report. As described in part 1, present key problem of scale-up utilization for biomass power generation technology is that China is very weak in general manufacture and production ability of biomass power generation related equipment. In order to advance China’s biomass power generation technology level and relevant energy equipment manufacturing ability, CRESP office particularly set up the Competitive Grant-in-aid Project according to GoC/ World Bank/ GEF, and entrust GIEC with the project implementation scheme, including the emphasis of technology advance items to be supported by ESCRP, qualifications for supported objectives and examination standard. These constitute part 3 of this report.

Development of Briquetting Machine Model BCYK

Abstract It is one of the sub-grant projects in the second round of of National Biomass competitive grant activities. It is planed that the project develops the biomass briquetting molding prototype with low energy consumption at normal tempreture, through reasearching the two core technologies of the formation of power transmission and molding module. The prototype changes the traditional “compression molding with positive pressure at high temperature ” to “grind molding with partial tensor at normal temperature”, which solves the problems of “poor force conductivity” and “high moisture” of the biomass raw materials of straw type from the mechanism, and reduces the pressure and energy consumption needed by molding radically. The molding machines improve effectively the stability of the equipment and extend the working life of the core components. The project is currently underway.
