    Residual biomass-based hydrogen production: Potential and possible uses in Ecuador
    (2020-05-11) Posso-Rivera, Fausto Rene; Siguencia, Jorge; Narvaez-C., Ricardo A.; Nuevas Tecnologías
    The residual biomass sources available in Ecuador are evaluated as prime matter for hydrogen (H2) production when considering that it sourced in agriculture, animal husbandry and forestry-related activities. The analysis is performed out of the official cropping information available per provinces. H2 production methods to be assayed consider thermochemical, biochemical and electrochemical paths. The total H2 production potential is 1,600,000 ton H2/year and its use as energy vector would contribute with 38% of the national energy demand in 2017. In addition, its potential application as input in fat hydrogenation and nitrogenated products, in a country-wide scale, would be completely fulfilled. This finding demonstrates that residual biomass-based H2 could become a suitable source of this vector for energy and chemical uses in Ecuador, since it proposes novel approaches for diversifying the secondary energy sources, petrochemical and chemical industry inputs with the purpose of promoting the incorporation of the country to the Hydrogen Economy.

    Use of Municipal Solid Waste (MSW)-Derived Hydrogen in Ecuador : Potential Applications for Urban Transportation
    (2019) Posso Rivera, Fausto René; Narváez C., Ricardo A.; Sánchez, Johanna Patricia; Siguencia, Jorge
    This paper performs an assessment of the potential energy-purposed H production in Ecuador from municipal solid waste (MSW). Thermochemical and electrochemical paths are considered for MSW conversion. Ecuadorian provincial MSW dis- tribution (2016 data) provides the base information for assessing and constructing maps of the theoretical H production yield and its density per unit area. Additionally, the use of H in fuel cell-propelled urban public transportation is proposed as an end-use consumer. Results show that it is possible to fulfl urban public transportation energy demand in 91% of the country with MSW-derived H2; in fact, the three provinces that together generate 57% of the available MSW (Guayas, Pichincha, and Azuay) could satisfy their public transportation diesel fuel demand with MSW-derived hydrogen. In the case of these three provinces, H2 generation could replace by 2.57 times (on average) the local urban transportation diesel fuel demand. Finally, a possible scenario for a non-conventional H2 production path is shown, which could also represent a suitable MSW fnal disposal alternative with benefts to urban mobility.
