pp 15-20
Abstract:The objective of this article is to describe hydrogen production through water electrolysis. Water electrolysis is the key to the functionality of energy accumulation systems in the form of stored hydrogen in the use of alternative energy sources (solar, wind, water, etc.). Systems using alternative energy sources connected with the electrolysers provide some flexibility, since the output can be electric energy or hydrogen itself. Hydrogen, as a medium for storing energy, can play a significant role with the increased use of renewable energy sources.
NUMERICAL CALCULATION OF THE PLASMA REACTOR HEAT RATE

Abstract:The publication aims to provide basic information about the results of temperature profiles calculation in the plasma reactor graphite hearth. Numerical calculation was divided into stationary and time dependent, calculated for the output of the arc 5 – 48 kW in the Ansys CFX software tool. Due to the deficit of the tool enabling the direct defining of the fourth state of matter as a heat source, a source was used in the calculations in the form of an isotropic radiant heat flow source.
MEASUREMENT OF CAPACITY HYDROGEN STORAGE

pp 26-29
Abstract:The paper deals with the determination of the physical and material properties of the La0.85Ce0.15Ni5 alloy with a crystalline and amorphous structure. Before of starting of measurement of hydrogen capacity, the alloy was activated in order to improve the storage capacity The activation procedure was as follows: changing the temperature in the range 0-100 ° C and pressure from -0.1 MPa to 5 MPa. The measurement of hydrogen storage capacity measurement was carried out at 10 ° C.
