Biogas production in rural areas of Mexico

Mexico is highly dependent on fossil fuels. One of the governmental initiatives proposes to investigate the possibilities for biogas production in rural areas. Agricultural producers are highly susceptible to energy price variations and in most cases the steadily growing prices of electricity and fu...

A detailed description of a proposed biogas production plant for a case study project at a milk farm in southern Mexico is presented in this study. Different stages and control strategies of biogas production as well as possibilities for biogas utilization in a small-scale CHP unit are assessed. Economical study was aimed to determine the financial flows of the sample project. A simplified economic analysis showed that the electricity produced in the biogas-driven CHP unit can compete with actual grid electricity prices. In addition, comparatively short payback time could be expected and the available governmental support schemes could be efficiency exploited for a commercially viable biogas production.
