The University of Zagreb, Faculty of Mechanical Engineering and Naval Architecture, (UNIZAG FSB) is a leading higher educational and research institution in the region covering wide range of research and teaching (http://www.fsb.hr/). UNIZAG FSB consists of 13 Departments that have been divided into several chairs and in total more than 400 people work on the Faculty. The Department of Energy, Power Engineering and Environment (DEPEE) offers education, research and development in energy engineering, energy management, environmental protection and fluid mechanics. It comprises four chairs and three laboratories: Chair of Environmental Protection and Water Treatment Technology, Power Engineering and Energy Management Chair, Fluid Mechanics Chair, Chair of Turbomachinery, Hydromechanics and Hydraulic Machinery Laboratory, Laboratory for Water, Fuels and Lubricants and Power Engineering Laboratory. DEPEE has 16 senior researchers, 13 junior researchers and 5 laboratory technicians. Power Engineering and Energy Management Chair has given special attention to the development of new fields in energy engineering, such as renewable energy sources, cogeneration, biofuels, energy storage, energy planning, energy efficiency and energy economics and management, so they are increasingly present in the R&D and teaching activities of the Chair. Chair of Environmental Protection and Water Treatment Technology is conducting research activities of application of advanced oxidation processes for the degradation of emerging contaminants
of concern which cannot be completely removed by conventional water treatment technology. Chair of Turbomachinery is conducting scientific work within projects funded by the Ministry of Science, Education and Sports and it has resulted in about 90 published scientific and professional papers.

Power Engineering Laboratory occupies an area of 400m2. Recently, the Laboratory has been used for conducting an intensive research on the possible use of solar equipment for electricity and hydrogen production. In this respect, photovoltaic technology, electrolysis and thermoacoustics are studied in particular. Laboratory for Water, Fuels and Lubricants conducts research for the purpose of scientific projects and in collaboration with industry, various experiments are conducted to reproduce laboratory-scale results in a pilot-scale system.
