Economic sustainability of biomethane: The green revolution in the transport sector.
The transport sector has a low penetration of renewable energy representing a serious obstacle to tackle the climate change. Biomethane isa decarbonisation solution and the recovery of some wastesupports the development of circular economy models. This presentation aims to investigate its economic sustainability. An integrated SWOT-AHP analysis is applied to the biomethane sector showing as the adoption of governmental support programs plays a key role. An economic model based on DCF methodology is proposedto evaluate the profitability of biomethane plants. Currently, production costs of biomethane are not competitive with fossil gas. Its discounted value varies from 0.61 to 0.88 €/m3 for by-products and from 0.64 to 0.91 €/m3 for organic waste. The economic feasibility is verified only in some scenarios and subsidies play a key role. Furthermore, the variation of critical variables significantly influences the profitability leading to the necessity to present alternative case studies. Currently, energy companies are interested in plants realization that recovered organic wastes due to the additional income obtained by their treatment. Finally, biomethane can be defined as a value added resource that integrates waste management and renewable energy supporting the reduction of the air pollution.
