“…Second, different regions may approve different policies for different alternative and transitional energy sources because production costs also depend on the regional characteristics, such as the availability of resources. For example, in Paraguay, the use of hydrofuel cell buses is an economically feasible alternative for diesel fuel buses [27]; however, the high price of EVs still limits its applications [28]. It is more difficult to reduce CO 2 emissions than it is to reduce reliance on diesel and gasoline consumption because the electricity used in hybrid EVs, PHEVs, and pure EVs (PEVs) in some regions is produced by using a high share of coal power [29].…”

In urban areas, the transportation sector is one of the principal sources of substantial energy consumption and carbon emission. Although diesel and gasoline are still the main energy sources used in urban transportation, alternative and transitional energy sources have been introduced. The alternative and transitional energy sources include electricity (used in hybrid, electric, and fuel-cell vehicles), biofuels, gaseous fuels from other sources (hydrogen, natural gas, and liquefied petroleum gas [LPG]), alcohols, and ethers. Alternative and transitional energy sources can be used to promote the development of sustainable transportation systems because these sources are renewable and have a lower environmental impact than diesel and gasoline. However, various technical, economic, and policy factors can prevent the successful application of alternative energy sources. In this review, we summarize the latest literature regarding alternative and transitional energy sources in order to understand the current applications of these energy sources in urban transportation and their future applications.

This paper performs an assessment of the potential energy-purposed H 2 production in Ecuador from municipal solid waste (MSW). Thermochemical and electrochemical paths are considered for MSW conversion. Ecuadorian provincial MSW distribution (2016 data) provides the base information for assessing and constructing maps of the theoretical H production yield 2 and its density per unit area. Additionally, the use of H 2 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 H 2; 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, H 2 generation could replace by 2.57 times (on average) the local urban transportation diesel fuel demand.Finally, a possible scenario for a non-conventional H 2 production path is shown, which could also represent a suitable MSW fnal disposal alternative with benefts to urban mobility.
