Biomethane Copyright Blaabjerg Biogas AmbaBiomethane is often overlooked as a viable transport fuel option, yet when produced from wastes can provide a highly competitive, low-cost transport fuel alternative. Biomethane upgraded for use in vehicles can be produced for between USD 0.45/lge and USD 0.55/lge from wastes, and between USD 0.65-0.75/lge when maize silage is added.

Large-scale production requires the purchase of feedstocks (e.g. maize silage) for the majority of the throughput and is thus more expensive. To the production costs for biogas, the cost of upgrading to biomethane must be added, but this typcially only accounts for 5-10% of production costs. The main constraint to the expanded use of biomethane is the need for a dedicated gas-based refuelling network and the relatively limited quantities of waste feedstocks relative to total transport demand.

Advanced biofuels to be competitive with fossil fuels by 2020.       Solar PV module prices of around USD 0.75/Watt makes PV the economic solution for 1.3 billion people.       Electric vehicle battery packs to fall 40% to 55% by 2020 to cost USD 300-400/kWh in 2020.       Some of today's first-of-a-kind commercial plug-in hybrid and battery electric vehicles are economic today.       Road transport accounted for 76% of total transport demand in 2010.       Biodiesel consumption grew 42% per year between 2000-2010.       Feedstock costs account for 60-80% of total conventional ethanol production costs.       The levelised cost of electricity of wind, solar PV, CSP and biomass is declining.       Electricity from hydropower, geothermal and biomass where good resources remain are the cheapest way to generate electricity.       Renewables are increasingly the most economic solution for new grid connected capacity.       Wind turbine prices have been declining since 2009.       Renewables are becoming the economic choice for off-grid and mini-grids.       Wind turbine prices in China in 2012 were USD 620/kW.       The installed cost of wind is typically lower than coal-fired power plants in OECD countries.
