Verification of the Green Microalgae Biomass Use for Biogas Production

Abstract

The article reviews the energy potential of microalgae as an alternative raw material for anaerobic digestion. Currently, energy security is one of the main topics among researchers. The amount of generated fossil fuels is limited, it is a question of time when fossil fuels will not continue to be accessible at low cost. There is a need to find an alternative carrier of energy which will replace the fossil fuels in the World. Green microalgae can be proposed as a possible bio raw-material, which can be used as an input material in order to produce energy. Lots of alternative technologies of algae cultivation are currently being developed all over the world. There is a necessity to search for a sensible way to produce algal biomass for bioenergy purposes, while maintaining all requirements involved in environmental and economic issues. The research results presented in the science article show that microalgae biomass is the proper alternative material for biogas production with the method of anaerobic fermentation. We believe that these research results can contribute to the future development of all forms of renewable energy in the Slovak Republic.

Biomass of Microalgae as a Source of Renewable Energy

Abstract

Algae represent a potential source of energy via anaerobic digestion. The aim of the study was to obtain the possible potential of green microalgae, which could replace the commonly used corn silage for the production of biogas in the future. The intensive construction of new biogas plants stations across Europe and the lack of arable land suitable for the cultivation of biomass for energy purposes are the fundamental reasons behind looking for the alternative raw materials for energy production as a substitute for commonly used input materials. When comparing green microalgae with conventional crops the high productivity potential (high oil content) as well as the possibility of their production during the whole year can be noticed. It is necessary to find the effective way to produce biomass from green microalgae, proper for energy conversion, while ensuring the economic and environmental aspects. The interim research results mentioned in this article indicate that microalgae present appropriate alternative material for the process of anaerobic digestion.
