The paper presents aspects of the hydrogen technology production using eletrolysis. Laboratory tests were done using an electrolyser connected to a photovoltaic energy conversion system. The worldwide growing energy consumption can be assured using renewable energy resources. CO2 emission reduction can be achieved by reducing dependence on fossil fuels. Based on statistical data and predictive models, solar energy is one of the most important renewable energy resources that has the potential to meet all energy needs in line with current trends. To generate 20 TW of power from the sun is necessary to cover an area of 816.000 km2 with PV modules. (Gratzel, M, 2011, Lewis 2006). The intermittent nature of solar energy can create difficulties for network operators, and converted energy should be stored in dedicated storage systems, which will ultimately increase the price of electricity. One way to solve these problems is to replace fossil fuels with hydrogen. The most important source for hydrogen is water, a convenient and abundant hydrogen resource. If the world energy consumption will be based on energy stored in hydrogen that can be assured from about 3.5 x1013 l water. This corresponds to 0.01 % of the annual rain fall or 0.000002% of the amount of water in world oceans.
