Biomethane
Biogas is caused by biological degradation of various types of biological waste, primarily biomass and organic matter of solid urban waste. Biogas is mostly composed of methane (CH4) and CO2.
Biogas is known as an ecological source of energy, while simultaneously alleviating two major ecological problems:
a global epidemic of waste that daily releases dangerous levels of methane
reliance on fossil fuel energy to meet global energy needs
Benefits of using biomethane:
vehicles that use biomethane do not emit CO2
the combination of biomethane (50%) and gasoline (10%) in vehicles reduces CO2 emissions and up to 53%
using waste for this purpose contributes to its better quality of disposal
The use of biomethane in the transport sector has great potential and potentially significant socio-economic benefits. The number of private vehicles, public, and trucks that use fuel gas is significantly increasing. Biomethane can be used in vehicles in the same way as natural gas. A growing number of European cities are replacing city buses on diesel fuel with those using biomethane. Vehicles powered by biomethane have significant advantages compared to equivalent vehicles on petrol or diesel fuel.
The total CO2 emissions are considerably less as well as emissions of particulates and soot (even compared with very modern diesel engines equipped with particle filters). Compared with other biofuels, biogas (biomethane) is considered to have the greatest potential as future-eligible fuel for vehicles that are most environmentally friendly.
