Energy is an issue of growing political and social significance. Electricity prices climb on a constant basis, worldwide energy consumption is increasing rapidly, however fossil fuels are finite. At the same time the environmental impact of burning
coal, oil, and gas and the problem of how to store nuclear waste is becoming ever more conspicuous. In light of these developments the demand for alternative energy sources is growing.
Biogas is a natural decomposition product thatoccurs when organic substances ferment.Production of energy from biogas is particularly environmentally-friendly, as it does not cause additional emission of the greenhouse gas CO2 and reduces the quantity of organic waste materials.In this way biogas significantly contributesto the reduction of CO2, and in many countries around the world it is promoted through statutory regulations. Biogas can be stored, so it is capable of supplying both base and peak energy loads. Unlike wind power and solar energy, biogas can be obtained regardless of climate and weather conditions.
Biomass is the only renewable energy source that is suitable for generating heat, power, gas as well as liquid fuels. The energy obtained from biogas is not only environmentally-friendly, it is also incredibly versatile. For example the
waste heat that occurs as a byproduct when generating biogas can be used to heat greenhouses or even for cooling. In particular the injection of biogas into the existing natural gas grid and use as fuel for automobiles will increase in significance in the coming years.
Biogas is an outstanding capital investment. Its production is safe and reliable; at the same time power production can be flexibly adapted to match consumption. Today biogas can be produced on industrial scale and marketed profitably. With fast construction times, low investment and consequential costs, biogas offers excellent returns and excellent added-value within a short time.
