All-rounder in sustainable development
Biogas is actually a mixture of gases, predominantly carbon dioxide (CO2) and methane. Methane is the enriching component, which is used for energetic benefits. Sludge, bio-waste and leftovers, farm residues such as dry maure and slurry and selective energy crops like corn are ideally suited as input. Biogas develops through microbial degradation of organic substances without oxygen. The biogas can be transferred to a Combined Heat and Power Unit (CHP). The electricity and heat produced in this way can be used off site or fed into the public grid.
The remaining substances are water and fermented organic material, which may be used as high quality fertiliser. Biogas is forward looking. A full supply is even possible by combining it with wind-waterpower, and photovoltaics.
Successful History of Renewable Energies in Germany
Renewable energies supplied 32,5 percent of gross power consumption in Germany 2015, which is a great historical development. The RENEWS Special “Twenty years of support for electricity from renewable energies in Germany” traces the unique development of renewable energies in Germany. The analysis describes the social background for the reorganization of the power supply system and the most important political and legal measures taken to set the course for the development of renewable energies, and provides a summary of the technological innovations achieved to date. Also in the UK the number of installed biogas plants is increasing, which is an extremely pleasant development. To get an overview about how many biogas plants are installed recently, we recommend you to watch this link: http://www.biogas-info.co.uk/maps/index2.htm.
