In the framework of the first Energy Climate Tech Forum, which took place at the Vienna Airport Conference & Innovation Center, Experts from the Energy Companies and Industry discussed ways how the sustainable transformation of energy and production systems, that involves major challenges and enormous opportunities, could look like. The forum intends to be an innovation platform for industrial companies with high energy consumption, accelerators and startups in the field of green energy, energy tech and climate tech as well as for energy producers and suppliers. Georg Wagner prepared the green H2 section of the conference. He was holding a brief introduction with an overview about opportunities, trends and road blocks towards a hydrogen economy. After this presentation he was conducting a panel with 2 leading experts for green H2: Alexander Fleischanderl from Primetals, a highly innovative company developing solutions for green steel production and Klaus Hofstadler from Lat Nitrogen, seeking to decarbonize its fertilizer production. The feedback from the audience was terrific!
