Okay okay, the historical development, the theoretical feasibility, the vision, a lot makes sense with the fuel cell. But apart from that, what about the practical application of this type of electricity generation in the here and now # Germany2020? After all, the microbiological fuel cell or bio-battery is still in its infancy and still has a few miles to go before it can run alone or is marketable.
Be careful, there is a business case that connects two social goals so elegantly that, thanks to the synergies that are released, viable use of microbiological fuel cells is already possible today. And that without, but especially when setting up funding programs. What is meant is the combination of energy generation (electricity) and wastewater treatment. As with the (hot) combustion of sewage gas in a combined heat and power plant, it can also be converted into electricity directly with the help of a microbiological fuel cell. In other words, using the flowing wastewater as a source of food for microorganisms. Integrated into a bio-battery, the bacteria not only clean the wastewater (biochemical oxygen demand, BOD), but also promote the targeted flow of electrons (electricity).
