We create green energy, from water!



Hydrogen Technologies d.o.o. is a company engaged in the research, development and production of hydrogen gas (H2) production, transportation and storage technology. The company was founded by professionals who have been in the business for more than a decade and have an interest and knowledge in developing technology that can contribute to a greener and more secure future. We are one of the few in Europe to begin manufacturing and installing Hydrogen Generators for IC engines (internal combustion engines) in 2009 and in 2013 the first to begin the implementation of Oxy-Hydrogen gas for the decarbonization of diesel and gasoline engines. Both technologies are based on the technology of hydrogen and oxygen gas production by an electrochemical process known as water electrolysis. In the last 10 years, our company has received numerous awards for its achievements in the development of this field.
