'Green' energy from algae

KIT 'algae platform' develops efficient photoreactors and novel cell decomposition methods

In view of the shortage of petrochemical resources and climate change, development of CO₂-neutral sustainable fuels is one of the most urgent challenges of our times. Energy plants like rape or oil palm are being discussed fervently, as they may also be used for food production. Hence, cultivation of microalgae may contribute decisively to tomorrow's energy supply. For energy production from microalgae, KIT scientists are developing closed photo-bioreactors and novel cell disruption methods.

Microalgae are monocellular, plant-like organisms engaged in photosynthesis and converting carbon dioxide (CO₂) into biomass. From this biomass, both potential resources and active substances as well as fuels like biodiesel may be produced. While growing, algae take up the amount of CO₂ that is later released again when they are used for energy production. Hence, energy from algae can be produced in a CO₂-neutral manner contrary to conventional energy carriers.
