AB  - Renewable hydrogen produced from the waste streams can be a good option for clean energy production and reduction of greenhouse gases emissions into the environment. In this study, the potential for hydrogen production from the food industry wastewaters in Serbia and the further use of the calculated potentials were investigated. This was performed through two technological routes including the biogas steam reforming process and the electrolysis after biogas cogeneration process. Furthermore, the environmental impacts of these processes were considered. The total hydrogen potential via the biogas steam reforming process was 4094.70 tons, while the total hydrogen potential via the electrolysis after biogas cogeneration process was 1751.08 tons. These potentials can be used for direct energy production in the food industry, electricity production for the national electric grid, transport, injection in the natural gas grid and/or as a resource in the chemical industry. Regarding the Greenhouse Gas emissions reduction, hydrogen production by both routes represents a promising pathway. The results of this work can serve the decision makers to plan hydrogen application in the energy sector of the Republic of Serbia defining supporting measures for its application. Also, the presented analysis is enforceable in the Western Balkan countries for the application of hydrogen as an energy source in their systems for energy production, transport and economy.

AB  - MgH2 based composites combined with NaNH2 were synthesized by mechanical milling for
three different milling times ranging from 15 to 60 minutes. Microstructure and particle
size of the samples were analyzed by SEM microscopy while desorption properties were
followed by Thermal Desorption Spectroscopy (TDS). The kinetic properties of NaNH2-
MgH2 composites were investigated by isoconversional kinetic method as implemented in
code developed by our group. Composites show hydrogen desorption peaks shifted to
lower temperatures in comparison to mechanically modified and as received MgH2. All
NaNH2-MgH2 composites show enhanced kinetics with lowered apparent activation energy
(Ea) in comparison to milled MgH2. The mechanism of desorption changes from Avrami
eErofeev n ¼ 3 for as received MgH2 to AvramieErofeev n ¼ 4 for composite materials.
The change from 3 to 4 can be due to the modification of the nucleation process or a change
in the dimensionality of the growth. Those high values of n disregard a diffusion control as
a rate limiting step. It has been shown that there is a synergistic effect on the enhanced
hydrogen storage performance of chemical reaction and structural changes caused by ball
milling. This can be used as a starting point for synthesis of innovative hydrogen storage
materials.
