The publisher Sven Geitmann, owner and founder of the Hydrogeit publishing house, had taken an intense interest in hydrogen and fuel cells as early as 1997 and became a contributor to energieportal24 and H2Report in 2000. After he wrote a number of technical books, he founded his own publishing company in the northwest of Berlin. In 2005, he took on responsibility for the former “H2Tec” magazine, which he renamed “HZwei”. This trade publication soon boasted a revamped design and more issues per year and grew into the quarterly must-read for everyone following the hydrogen and fuel cell market.

In 2015, Hydrogeit Verlag created the global English-language edition H2-international. Since then, it has kept readers in all corners of the world up to date on what’s happening in the sector.

Since spring 2002, he has been working independently as an author and specialist journalist in the field of renewable energies, hydrogen, and fuel cells. In February 2004, he established the Hydrogeit Publishing House, the first specialized publisher for renewable energies, hydrogen, and fuel cells. HZwei, the magazine for hydrogen and fuel cells, has been published here since 2006, along with its English counterpart, H2-international, the e-Journal on hydrogen and fuel cells, introduced in 2015. Welcome to H2-international, your trusted source for all things hydrogen and fuel cells.
