addition to his role as the director of HI ERN is a co founder and member of the scientific adviso ry council at Hydrogenious says At the moment this onboard technology cannot be accommodated underneath the hood of a small car yet but it defi nitely can be in the technical operations sections of a train or ship Our goal is to make these units increasingly powerful smaller and compact Going forward that may definitely be heading in the di rection of trucks buses construction machinery forestry machines or mine vehicles with prospects up to and including small trucks or large passen ger cars Industrializing hydrogen technologies No matter in which ways hydrogen will be trans ported transformed or used it has to be produced first The 1 5 degree scenario of the Internation al Organization for Renewable Energies IRENA predicts an electrolyzer capacity of 5 000 giga watts for 2050 which would make enough hy drogen available to cover twelve percent of the global energy demand That means that 50 000 large scale electrolyzers the size of the plant in Hamburg Moorburg would have to be established worldwide Technological innovations and their accelerat ed rollout are of crucial importance to ensuring that this will happen Equally important is the achievement of competitive economic feasibility of carbon free hydrogen as soon as possible One of the keys to success in this regard is the provi sion of sufficient and low priced green electricity by expanding renewable energies The fact that today gray hydrogen produced with fossil energy costs only a fourth of what green hydrogen costs shows the need for action in this area Potential cost reductions with a view toward scaling and market ramp up of the technologies are another key to success Schaeffler intends to make important contribu tions to this effort based on its diversified tech nological know how Due to our industrial and automotive divisions we re optimally poised to address hydrogen on a broad base We have a unique competitive advantage here especially be cause an industrialized supplier landscape is still lacking in many areas of hydrogen technology says Dr Stefan Gossens Vice President Hydrogen Strategy at Schaeffler We re already in contact with many potential hydrogen customers in a wide range of business activities Our forte in industrial ization enabling us to quickly transfer innovations into mass production at top quality is a major advantage Water will one day be employed as fuel It will furnish an inexhaustible source of heat and light of an intensity of which coal is not capable Jules Verne in 1874 in his novel Mysterious Island is the power to hydrogen efficiency of current electrolyzers The efficiency of reconverting hydrogen into electricity in a fuel cell is currently 60 80 In the end about 50 of the energy filled into the tank of a fuel cell car arrive at the wheels That puts a hydrogen passenger car between a car with an IC engine 25 45 and a battery electric car 75 90 60 75 Sources sfc com auto motor sport 51 RENEWABLE ENERGIES
