Hydrogen Economy

Hydrogen economy is the synonymous for sustainable energy system in which pure hydrogen replaces fossil fuels – hydrocarbons. In order to be successful and sustainable hydrogen economy, hydrogen should be produced using renewable energy sources (RES). One of the recommended technique is the hydrogen production via water electrolysis using Solar energy.

Faculty of Mechanical Engineering and Naval Architecture

Faculty of Mechanical Engineering and Naval Architecture (FSB) is a member of University of Zagreb. It was founded in the year of 1919 and is considered as the one of the most prestigious technical faculties in the Republic of Croatia.

Laboratory of Power Engineering

The Laboratory of Power Engineering focuses towards new clean technologies based on using hydrogen as the energy storage and renewable energy sources (RES) with an emphasis on Solar energy.


First Croatian hydrogen fuel cells powered bicycle

Hydrogen powered bicycle is the electric bicycle that electric energy needed to run electric motor gets from the fuel cell stack. Particularly for this bicycle, it is a PEM fuel stack with total power of 300 W.

Solar power plant

Solar power plant is installed on the top roof of Laboratory of Power Engineering. With a total installed power of 960 Wp, a produced electric energy is used for hydrogen production via water electrolysis, i.e. energy storage.

First Croatian hydrogen refuelling station

The project is based on the ecological solution of using Solar energy to produce alternative fuel, i.e. hydrogen for cleaner transport, which will reduce air pollution and improve the quality of life in the cities. This project has been awarded by Croatian Telecom Inc. (HT) as the best project in the category of Innovation.

Refuelling stations for battery powered electric vehicles

Within the outside area of Faculty of Mechanical Engineering and Naval Architecture (FSB), there are installed two chargers for battery powered electric vehicles and thus we became the first e-Faculty in the Republic of Croatia. In this way, FSB placed itself in the prestige category of world e-Faculties. Each of the two charges is equipped with two 22 kW ports for simultaneous charging of two vehicles.



Hydrogen production

Today, hydrogen is mainly produced by reforming of hydrocarbons with water vapor, and via water electrolysis. Although hydrogen production via reforming is the three times cheaper than water electrolysis, the main disadvantage of such a process is the harmful carbon dioxide (CO2) emision.


Hydrogen storage

Hydrogen storage is divided into mass (stationary) and mobile (for vehicles). The effective hydrogen storage is the key to wider acceptance of hydrogen technologies in general.


Hydrogen distribution

Hydrogen can be distributed through pipelines already existing in hundreds of miles across the Europe and the United States (US). Furthermore, it can be compressed into above ground and underground pressurized storage tanks. It can also be liquefied and stored in cryogenic storage tanks.


Hydrogen utilization

Hydrogen can be used as a fuel in internal combustion engines and gas turbines, or can be mixed with natural gas and burn on the steam generator burners. It is also possible to utilize it in the chemical industry and households. But the most attractive technique is hydrogen utilization in fuel cells.


State of the art and perspectives

Considering the awareness of global warming and the importance of environmental protection, today’s market trends are such that hydrogen is a constituent part of almost all energy strategies and directives. Scientific researches on hydrogen fuel cells in conjunction with renewable energy sources (RES), demonstration projects, and their application are present in all EU framework programs as one of the seven key technologies of the 21st century. In the developed world technology is developing exponentially and it is in political focus because it is a condition of survival and retention of the existing global positions of the state economy.
