“…Among these items, maintenance and overhead is the most relevant cost varying from 46%-50% when ofmsw substrate is used and from 24%-29% with mixes. These considerations are obtained for 100−1000 m 3 /h plants, and the results underline that transport costs become more relevant than maintenance and overhead costs when a 1000 m 3 /h plant is considered for a mixed substrate [13].…”

“…The use of biomethane is able to reduce emissions further. This value is equal to 24 gCO2eq/km, if CNG is composed also by 20% of biomethane (also The biogas-biomethane chain is able to tackle the environmental pollution as an alternative to the consumption of natural gas [13]. GHG emissions of vehicle powertrain systems are recorded from the Well To Wheel (WTW).…”

“…The economic feasibility of biogas plants is well defined in the literature [28], but also, the analysis of biomethane production is analyzed for several final uses (fed into the grid, destined for cogeneration or sold as vehicle fuel) [13]. However, there are several approaches.…”

“…The biomethane cost of production is 0.54 €/m 3 injected into the grid and 0.73 €/m 3 as transportation fuel [30]. The discounted total cost for the organic fraction of municipal solid waste (ofmsw) substrate varies from 0.46-0.82 €/m 3 , while it is equal to 0.49-0.76 €/m 3 for a mixed substrate (maize and manure residues) [13].…”

“…A previous analysis underlining the profitability of ofmsw substrate is verified with the following configurations: a minimum size for the plant of 100 m 3 /h if the biomethane is used for cogeneration and 250 m 3 /h for the other two final destinations. Instead, the financial feasibility of mixed substrate is verified only for a 500 m 3 /h plant if the biomethane is used as vehicle fuel [13].…”

Biomethane: A Renewable Resource as Vehicle Fuel

Abstract:The European Union (EU) has set a mandatory target for renewable fuels of 10% for each member state by 2020. Biomethane is a renewable energy representing an alternative to the use of fossil fuels in the transport sector. This resource is a solution to reach this target. Furthermore, it contributes to reducing carbon dioxide emissions, gives social benefits and increases the security supply. Sustainability is reached also when the economic opportunities are verified. This work studies the profitability of small plants of biomethane, which is sold as vehicle fuel using the Net Present Value (NPV) and Discounted Payback Time (DPBT). The paper shows in detail the method used for the economic assessment of two typologies of feedstock recovered: (i) municipal solid waste and (ii) agricultural waste. Detailed information about the various parameters that affect the profitability of biomethane is given, and several case studies are analyzed as a function of two variables: subsidies and selling price. The results support the commercialization of small-scale plants, reducing also several environmental issues. The role of subsidies is strategic, and the profitability is verified only in some case studies.

Buses account for almost 60% of the total public transport services in Europe, and most of the vehicles are diesel fuelled. Regional transport administrators, under pressure by governments to introduce zero-emission buses, require analytical tools for identifying optimal solutions. In literature, few models combine location analysis, least cost planning, and emission assessment, taking into account multiple technologies which might achieve emission reduction goals. In this paper, an existing optimal location model for electric urban transport is adapted to match the needs of regional transport. The model, which aims to evaluate well-to-wheel carbon emissions as well as airborne emissions of NOx and PM10, is applied to a real case study of a regional bus transport service in North Eastern Italy. The optimization has identified electric buses with relatively small (60 kWh) batteries as the best compromise for reducing carbon equivalent emissions; however, under current economic conditions in Italy, the life cycle cost of such vehicles is still much higher than those of Euro VI diesel buses. In this context, our model helps in identifying ways to minimize infrastructure costs and to efficiently allocate expensive resources such as electric buses to the routes where the maximum environmental benefit can be achieved.
