Biomethane is a renewable energy source which can be used in multiple ways, including power generation, heating or as a biofuel. It can be produced from various agricultural raw materials and residues. In particular, it can be made from agricultural residues, such as manure, slurry, organic waste and straw.
As an advanced 2nd generation biofuel verbiogas is a renewable energy source that does not compete with food. It is made from slop - a residue from bioethanol production - and from straw. Digested residue conduces as a bio-fertilizer for agriculture.
After fermentation the biogas is purified and conitioned to to the quality of natural gas and fed into the existing natural gas grid. In fact biomethane has the same chemical composition as natural gas. Both can be mixed to any extend.
Biomethane is the most efficient (bio)fuel there is. It has a much higher energy density than any other fuel. Compared to gasoline biomethane reduces CO2 emissions by up to 90% and fuel costs by ca. 50%.
