Increasing volumes of MSW (municipal solid waste) pose disposal problems for many cities. Costs are rising as landfilling becomes more difficult. The production of clean transportation fuels (methanol or hydrogen) from MSW is one economically and environmentally promising option for dealing with these problems. An attractive feature is that elimination of essentially all air pollutant emissions is inherent in the process. Methanol or hydrogen used in FCV (fuel cell vehicles) can help address problems of deteriorating urban air quality due to vehicle pollution and heavy dependence of the transport sector on imported petroleum. Buses are initial targets for commercial application of fuel cells. Coupled with FCV's, MSW could become a major transportation energy resource. For example, less than 25 % of New York City's MSW supple would be sufficient to produce the methanol or hydrogen needed to fuel the entire city's bus fleet, if the buses were fuel cell powered. Estimated breakeven tipping fees required for hydrogen or methanol from MSW to compete with the cost of these fuels made from natural gas today are USD 52 to USD 89/raw tonne MSW for hydrogen and USD 64 to USD 104/raw tonne MSW for methanol, depending on the gasification technology considered. For comparison, the average tipping fee today in New York City is USD 74/tonne. Because of the high fuel economies expected for fuel cell buses, total lifecycle costs per bus-km could be lower than for conventional diesel-engine buses.
