In the commercial vehicle sector hydrogen as a propulsion source has already become well established For instance 50 000 forklift trucks worldwide now have a fuel cell on board Most manufacturers such as Linde Jungheinrich Toyota and Still off er a hydrogen version of their forklifts and many large companies are gradually changing their intralogistics fl eets as part of their transformation towards CO2 free manufacturing The industry network Clean Intralogistics Net CIN supports this development and Schaeffl er is on board as well Together with other partnering companies CIN is driving the market activation and market development of the fuel cell in intralogistics With 77 production plants Schaeffl er is also a potential user of fuel cell powered forklifts The network members represent the entire value chain from manufacturers of forklifts and fuel cells to component and gas suppliers to users of the technology In the truck segment there s a lot of momentum towards hydrogen Practically every manufacturer is currently working on hydrogen models and the fi rst prototypes have already been deployed to fl eets Volvo and Mercedes recently entered into a joint venture for mass production of fuel cells The advantage of commercial vehicles over passenger cars is that they travel according to pre planned schedules and routes so that the sparse fi lling station network is not as critical Plus due to the fact that commercial vehicles are typically on the road all the time the operation of an IC engine with liquid hydrogen is conceivable as well Consequently the disadvantage of hydrogen evaporating when the vehicle is not being used for longer periods of time is clearly less critical than in the case of passenger cars Fuel cell technology is near perfectly suited for use in garbage trucks because green hydrogen for their powertrains can be produced directly from biogenic waste at incineration plants German vehicle manufacturer Faun is planning to launch mass production of such a garbage truck in 2021 featuring a hybrid powertrain with a fuel cell serving as a range extender for the battery electric drive system Dr Stefan Gossens High performance long range fast refueling and lower weight compared to batteries in commercial vehicles hydrogen can display its strengths even more eff ectively than in passenger cars The tens of thousands of forklifts existing by now have shown that the technology is also suitable for mass deployment in the fi eld Increasing use of hydrogen trucks would also boost the expansion of H2 fi llings sta tions Hyundai has projected that such a facility would be profi table if just 15 trucks would regularly fi ll their tanks there H2 in commercial vehicles of gaseous hydrogen are suffi cient for propelling the hydrogen bike presented by Linde in 2015 across a distance of 100 kilometers 62 miles Afterwards the tank would be refi lled in six minutes At CES in Las Vegas in 2019 the French company Pragma Industries unveiled another hydrogen bike called Alpha 2 0 that s primarily intended for use by fl eet operators Initial prototypes are on the road in the motorcycle segment as well However Schaeffl er s expert Dr Stefan Gossens feels that the H2 bike market is an absolute niche His conclusion There s no potential there for hydrogen 34 grams 1 2 oz Like many truck manufacturers Daimler Trucks is pursuing fuel cell technology in the electrifi cation of its vehicles from urban distributors to international long distance haulers Pictured above are sketches of the GenH2 concept vehicle with a targeted range of 1 000 km 621 mi Its mass production launch is planned for the middle of this decade 57 Here and now
