At the beginning of July, ambassadors of 27 EU states and representatives of the EU Council visited our region, Ostrava and the Lower Vítkovice region. A total of more than 100 representatives from all over the EU visited us on the occasion of the Czech Presidency of the Council of the EU in the 2nd half of 2022. As part of a tour of Dolní Vítkovice and the Landek Mining Museum, we used the opportunity to present our hydrogen technologies on behalf of the entire Cylinders Holding. In addition to having the opportunity to drive a Toyota Mirai, the ambassadors saw our hydrogen trailer, hydrogen storage, a presentation of our hydrogen applications, oxytherapy and also had the opportunity to taste hydrogen water. The interest of the ambassadors was evidenced by their inquisitive questions and lively discussion on the topic of the use, storage and transportation of hydrogen. As part of ensuring energy self-sufficiency, hydrogen is one of the key sources of energy, and it can be seen that state representatives are increasingly aware of this.
