German Biogas Project Recycles Wastewater to Grow Corn

Biopact reports on the construction of a €10 million (US$13 million) biogas complex in Germany that includes a dedicated field of corn watered by wastewater, a pipeline and a combined heat-and-power plant.

Corn will be raised on a dedicated plot of 10 square kilometers (2471 acres). The entire plant's biomass (grain, cobs, stems, leaves) will be fed to a fermentation process which produces biogas. The unpurified biogas will be pumped to the city of Braunschweig, via a 20 km (12 mile) pipeline, to a combined heat-and-power plant which converts the energy contained in it with an efficiency of almost 90%. The heat and power will satisfy the total energy demand of some 7000 households. The biogas maize will be irrigated with waste water from Braunschweig.

According to a German bioenergy expert, "This is the perfect closed loop. Waste water, renewable biomass, biogas, heat and power. This holds a lot of potential, also for the developing world":

According to some German analysts, locally produced biogas can replace all of the country's natural gas imports from Russia by 2030, others put its potential at half that amount. The green gas can be purified to natural gas standards and fed to the gas grid. It is also being used more and more often as an automotive fuel, particularly in Central and Northern Europe.

Interesting,

Yes we already have biogas here in Germany... Unfortunlately we cannot tank biogas in our both cars because we don't have biogas in our cars...

My friend have one and told me that it's good but how long?

Come and discuss what you think of this. Its about future... because of oil and gas expenses...

It might be OK if they limit how much farm land is used for this. It's not good to use up or mix farm land for food use and fuel use. Also, it depends on how much cost is involved in the growing and production cycle, from plant to fuel, compared to regular gas costs. Since it uses waste products, that should keep the cost down.

I don't know if it can feasibly replace 100% of Germany's natural gas imports.
