The 2nd HyLand specialist workshop on the topics of hydrogen storage, transportation and distribution took place on Tuesday, 14 June 2022 at the city of Mainz municipal utilities – the Mainzer Stadtwerke. Mainz, which is the capital city of Rhineland-Palatinate and itself a HyExpert in the second HyLand phase, played host to the hybrid event with a total of 65 participants.

A multifaceted programme awaited the HyLand network. Besides news on the funding landscape and the presentation of the HyLand network activities by NOW, technical, economic and regulatory aspects of the hydrogen infrastructure were highlighted. Prof. Dr. Birgit Scheppat (Rhine-Main University of Applied Sciences), Oliver Antoni (Stiftung Umweltenergierecht) and Tilman Wilhelm (DVGW) delivered compelling presentations on this topic. Practical experience with the conversion of natural gas pipelines to hydrogen (H2HoWi project) was also presented by Carsten Stabenau (westnetz). Volker Hans and Hilmar-Andreas Holland presented the regional hydrogen project approaches of the two HyLand regions HyExpert-Landeshauptstadt Mainz and the neighbouring HyStarter region Rheinhessen-Nahe. Anne Wincheringer (Mainzer Stadtwerke) reported on practical experiences from the seven-year operation of the Mainz Energy Park. The event was moderated by Dr. Thomas Kattenstein (EE ENERGY ENGINEERS GmbH).

20 local participants toured the Energiepark Mainz following the presentations and technical discussions. Since July 2015, the energy park has been producing hydrogen from wind power, which is then filled into trailers and supplies the hydrogen filling station in Wiesbaden. The trip to the Energiepark Mainz was made with the fuel cell bus from Mainzer Mobilität.
