Daimler Vans begins rigorous testing of fuel-cell truck | Automotive Business Information

Daimler Vans says it hopes to begin testing a hydrogen fuel-cell truck prototype on public roads later this yr.

It goals to attain ranges of as much as 1,000 kilometres and extra with none stops for refuelling. In late April, the truck producer started to conduct rigorous exams of the primary new enhanced prototype of its Mercedes-Benz GenH2 Truck, which was unveiled in 2020. This marks an essential milestone on the trail to collection manufacturing. Throughout these exams, the builders at Daimler Vans are placing the fuel-cell car by means of its paces. The intensive collection of exams could be very demanding for the car and its elements, and focusses, amongst different issues, on steady operation, totally different climate and street situations, and numerous driving manoeuvers.

Based on Daimler Vans’ improvement plan, the car can even be examined on public roads earlier than the top of the yr. Buyer trials are scheduled to start in 2023. The primary series-produced GenH2 Vans are anticipated to be handed over to clients beginning in 2027.

Martin Daum, Chairman of the Board of Administration of Daimler Truck AG and Member of the Board of Administration of Daimler AG: “We’re persistently pursuing our expertise technique for the electrification of our vans. We need to provide our clients the very best domestically CO2-neutral vans — powered by both batteries or hydrogen-based fuel-cells, relying on the use case. We’re proper on schedule and I am delighted that the rigorous exams of the GenH2 Truck have began efficiently.”

“The hydrogen-powered fuel-cell drive will turn into indispensable for CO2-neutral long-haul street transport sooner or later. That is additionally confirmed by our many companions with whom we’re working collectively at full steam to place this expertise on the street in series-production autos. Furthermore, appreciable momentum is being generated by the clear dedication of nationwide and European regulators to using hydrogen for street freight transport. Political assist performs an essential function in selling the creation of an infrastructure for inexperienced hydrogen and making an economically viable use of fuel-cell vans attainable for our clients,” Daum provides.

Demanding exams for 1.2 million kilometres of working efficiency

The event engineers at Daimler Vans are designing the GenH2 Truck in order that the car and its elements meet the identical sturdiness necessities as a comparable standard Mercedes-Benz Actros. This implies 1.2 million kilometres on the street over a interval of ten years and a complete of 25,000 hours of operation. That is why the GenH2 Truck has to finish extraordinarily demanding exams — identical to each different new Actros technology. Through the first few weeks of testing, the car has already lined a whole lot of kilometres beneath steady load on a road-to-rig check stand and gone by means of many excessive conditions which are primarily based on real-life working situations. Examples embrace emergency braking and kerbstone drives alongside the check monitor.

Fully new car idea and new elements

The GenH2 Truck has been newly designed from the bottom up. It options utterly new elements, which the builders are notably specializing in in the course of the exams. These elements embrace the fuel-cell system, the all-electric powertrain, and the entire related techniques such because the particular cooling unit. As well as, the brand new elements’ particular weight and place within the car have an effect on the truck’s dealing with properties. Consequently, the vibrations brought on by bumpy roads, for instance, and particularly by excessive conditions, topic the fuel-cell truck to totally different forces than these in standard autos. With a view to receive intensive details about this at an early stage, the present prototype is loaded in the course of the exams with a payload of as much as 25 tons for a gross car weight of about 40 tons, which is equivalent with the specs deliberate for the series-produced variant of the GenH2 Truck.

Liquid hydrogen presents many benefits

Daimler Vans prefers to make use of liquid hydrogen as a result of on this state, the power service has a far larger power density in relation to quantity than gaseous hydrogen. Consequently, the tanks of a fuel-cell truck utilizing liquid hydrogen are a lot smaller and, because of the decrease stress, considerably lighter. This provides the vans extra cargo house and the next payload. On the identical time, extra hydrogen could be carried, which considerably will increase the vans’ vary. This makes the collection GenH2 Truck, like standard diesel vans, appropriate for multi-day, difficult-to-plan long-haul transport and the place the day by day power throughput is excessive.

The consultants at Daimler Vans are forging forward with the event of tank applied sciences for liquid hydrogen on the idea of a predefined improvement plan. By the top of the yr, the engineers plan to have the brand new prototype tank system sufficiently mature for use to proceed the continuing demanding exams of the GenH2 Truck. The car exams will then be carried out solely with liquid hydrogen tank techniques till the series-production stage is reached. Till this may be carried out, the intensive inside testing of the GenH2 Truck will use a gaseous hydrogen tank system as an interim answer. Daimler Vans is thus demonstrating that each variants – gaseous and liquid – could be technically carried out.
