Abstract

The demand for hydrogen is expanding, which has led to research into hydrogen manufacturing. Analyzing options for lowering the environmental effect of petroleum-based fuels can be made easier with an understanding of the process by which biomass is transformed into hydrogen gas. This experiment evaluated the culture and growth performance of Spirulina platensis in supernatant derived from digested rotten potato (DRP) supplemented with a thin layer of sour yogurt to enhance algal growth and compared it to Kosaric medium (KM) as a control. Three concentrations of DRP (25%, 50%, and 75%) were used, with Spirulina inoculated in the supernatant for 14 days. The highest cell weight was observed in KM on the 10th day. Spirulina grown in 50% DRP supernatant showed significantly better growth performance than those in 25% and 75% concentrations. The crude protein content was slightly lower in Spirulina cultured in DRP compared to KM, while crude lipid content was substantially higher in 50% DRP compared to KM. Additionally, microwave plasma pyrolysis of Spirulina algae was studied for hydrogen production, with experiments conducted at power levels of 800, 900, and 1000 W, a reactant flow rate of 12 slm, and 1 g of dry Spirulina algae in nitrogen. At the absorbed microwave power levels used in this experiment and yielding hydrogen gas in the range of 12.37-31.46 mg of hydrogen per gram of algae consumed. These findings enhance the understanding of Spirulina cultivation in alternative media for high lipid content and demonstrate the potential of Spirulina algae as a biomass source for hydrogen production using microwave-assisted pyrolysis.
