Biogas Turning Agriculture to Energy Producer with Biogas
Germany's energy transition is among the most ambitious projects in technology politics. It will need efforts from all branches and technologies to cut the country's dependency on fuel imports and reduce carbon dioxide emissions - Biogas could play a major role. Discover, how biogas specialists can turn agricultural business to energy industry.
Since 1752 ,the Wenning family has run a successful agricultural business and distillery. 30 years ago, they took the first pioneering steps towards onsite biogas production. Together with the help of Atlas Copco, they now have evolved into an award winning energy producer, using 50% less power than other, comparable plants.
By 2020, 20% of all energy and 10% of all transport fuel should come from renewable sources. To reach these European targets, countries are rethinking their energy mix. Germany is extensively promoting biogas as an alternative source of energy.
Biogas Offers Storage Capacity for Energy
“In comparison with other sources of energy, like electricity for example, the biggest advantage is storability. We can store up to two months’ worth of energy”, says Bernd-Josef Wenning. As biogas is stored in the existing gas network, it doesn’t have to be consumed immediately and no additional investments in the gas grid is required.
In Germany, over 6000 anaerobic digesters convert biomass into raw biogas. This number will more than double over the next ten years. “The energy cycle is simple: the distillery contributes with residues that feed the bulls”, Wenning explains. “The bulls give manure in return, a raw material for the biogas plant. The plant delivers gas, which is used to generate electricity and steam. This is a closed loop that really makes sense.”
