The technology for producing hydrogen from solid municipal waste using algae was proposed by scientists of St. Petersburg Polytechnic University.
According to them, the addition of biomass of microalgae of the genus chlorella to landfills accelerates the fermentation of waste for the processing of landfill gases into biohydrogen.
The result is presented in the International Journal of Hydrogen Energy.
Solid municipal waste is stored in special landfills, which during operation and for a long time after closure are sources of landfill gas emissions into the atmosphere.
Landfill gas partially consists of methane thanks to which it can be used as a secondary energy resource. The gas enriched with this hydrocarbon can be used to produce another type of unconventional fuel – biohydrogen.
At the same time, according to scientists, due to the processing of microalgae biomass and organic waste, disposal costs can be reduced by 20% - 30%, ria.ru reports.
