Biomass energy is not a new phenomenon. Many farmers have installed on their lands, for example, appropriate equipment and there turn their farms organic waste into energy. Criticism is get the bio-energy but because more and more crops are grown specifically for this purpose. Are used then so not only the waste makes sense, but whole fields occupied by then no longer stand for the food production available – one speaks of the so-called “Tank or plate”-problem. Increasingly therefore algae got into the focus of scientists in this field. They produce around five to ten times as much biomass as normal land plants and can be grown without that for agricultural land are occupied.
A first example of this can be seen in Berlin at the EUREF campus. There, the Palmetto GmbH has its headquarters. The company had a so called photo bio-reactor on the facade. This consists of a rising upwards Helix of tubes through which water flows. The algae are grown in the tubes in turn. For the growth of plants, it is also necessary to enrich them with CO2. Theoretically algae could later once so also serve to save greenhouse emissions from conventional power plants. Otherwise you can find a wide variety of application possibilities for algae but.
