The company was founded by experts who have been in this business for more than a decade. Its main goal is to contribute to a greener and more sustainable future in terms of energy. We are one of the few firms in Europe which started the production and installation of the hydrogen generators for internal combustion engines (ICE) in 2009. We were the first to start using Oxy-Hydrogen gas for decarbonization of diesel and gasoline engines. Both technologies are based on the producing hydrogen and oxygen by an electrochemical process known as water electrolysis. Our company has received numerous awards in this field in the last 10 years. “Decarbonization Center“ (DC) is a branch (brand) under “Hydrogen Technologies” d.o.o. company’s umbrella. DC is engaged in the production and franchising of the high quality machines with CE marking for IC engine (petrol and diesel) decarbonization, as well as in providing the service of engine decarbonization. The DC brand is growing globally and actively expanding its franchise network worldwide. Its decarbonization machines are already present in many countries such as Germany, Great Britain, Denmark, Hong Kong, Czech Republic, Slovakia, Hungary, as well as in the Western Balkans region.
