[hal-01107615] Rice husk gasification for electricity generation in Cambodia in December 2014

Rice husks are the indigestible coatings of grains of rice. They are produced in large quantities by the rice milling industry, more than 1 million ton per year in Cambodia. In recent years, Cambodian enterprises have installed gasifiers, which burn rice husks to generate electricity. This is a two stage process: the biomass is first fed into a gasifier which produces syngas and ashes, then the syngas is cleaned and burned into an engine where it saves diesel fuel. Many of these enterprises have been in local communities currently without electricity or in fuel poverty. To learn more about the benefits and drawbacks of using rice-husk gasifiers, and to study about the sustainability challenges for deploying these technologies, the Clean energy and sustainable development lab (CleanED lab) of the University of Science and Technology of Hanoi (USTH), and the SNV Netherlands Development Organisation (SNV) have conducted a visit of several rice mills and rural electricity enterprises from 18 th to 22nd December 2014. Five rice mills and a rural electricity enterprise in Battambang, Siem Reap and Kampong Thom provinces were selected for the field survey. In addition with desk research, semi-structured interviews with gasifier users, with the representatives of Canadia Bank PLC and the Federation of Cambodian Rice Millers Association (FCRMA) during the field surveys were also conducted. This report present and justifies the main conclusions of the visit.
