7 Options to address Large Scale Grid Storage are limited Key Statements Ammonia/ Methane There is no universal solution for electrical storage Large scale storage can currently only be addressed by - Pumped Hydro - Compressed Air (CAES) - Chemical storage media, like Hydrogen, Ammonia and Methane Page 9 / 5 December 2017

8 PEM Electrolyzer: H 2 drives the convergence between energy & industry markets Application Focus Large Refueling scale station production for for cars industrial & busses use, e.g. MT/HT-heat, as process chemical Conversion and to renewable hydrogen for feedstock energy Conversion storage and wind energy to balancing hydrogen grids for balancing e-grids, seasonal energy storage and high volume On-site energy production transport and use Refueling station for cars & busses Page 10 / 5 December 2017
