Representatives of energy authorities from the Gulf region visit clean energy sites in Germany in the framework of the clean energy study tour organised by the EU GCC Clean Energy Technology Network. The initiative is coordinated with the Gulf Cooperation Council Secretariat General (GCC SC) and it aims to promote the exchange of experiences and know-how between the EU and the GCC on clean energy technologies and applications, mainly on renewables and electricity interconnections. At the ZSW in Ulm, Dr. Alexander Kabza from the Fuel Cell Systems Department spoke about the opportunities and challenges of hydrogen as the energy carrier of the future. The tour took the participants via the H2 filling station to the laboratories for hydrogen analysis and the fuel cell test centre.
