Abstract: Mexico generated 35.4 million tons of urban solid wastes in 2005 of which 51% were organic ones. This biomass can be fermented into H₂ when H₂-based technologies increase their market penetration for the year 2020. The purpose of this work was to review studies that have utilised organic solid wastes for fermentative H₂ production and to evaluate the potential for Mexico. The experimental H₂ yields (m³ H₂/kg VS) were 0.283, 0.151 and 0.052 which correspond with low-, medium- and high-input substrate concentrations. Therefore, a potential of H₂ production of 1.38 × 10⁵ tons H₂/year for the 2020 was calculated which could supply 20% of the future requirements for fuel cells vehicles in the Metropolitan Area of Mexico City.
