At CES this previous week, the trucking startup Nikola showed off a hydrogen-fueled semi truck, one in every of its first ever constructed within the U.S. However the troubled firm with a convicted founder will not be the one participant today seeing a promising future in fuel-cell fueled massive rigs. Daimler Truck has additionally lately introduced their GenH2 electric semi. GenH2’s motors draw energy from a gas cell that runs on liquid hydrogen, and Daimler has stated the car will seem on German roads by mid-2024.
The corporate has entered agreements with a number of corporations which have fleet operations within the German area, the place Daimler successfully tested a GenH2 prototype on a monitor and on public roads. Through these early highway assessments, the corporate says they’ve discovered {that a} absolutely loaded GenH2 proved able to hauling its roughly 25-ton payload greater than 1,000 kilometers on a single fueling.
Underneath the Hood of the GenH2 Truck
The fuel-cell system of the GenH2 Truck, in line with the corporate, delivers 300 kilowatts. The truck additionally has a battery that may kick in a further 400 kW briefly bursts for fast acceleration and hill climbing. The battery’s 70 kilowatt-hour storage capability could seem small, bu appears it’s ample for recycling kinetic vitality that’s transformed to electrical cost by way of regenerative braking.

Daimler, together with Linde and Air Liquide, the German and French multinational suppliers of business gases and hydrogen refueling providers, are profiting from advances in liquid hydrogen storage that yield notable benefits over utilizing pressurized gasoline.
In its liquified state, extra hydrogen may be carried per unit quantity in comparison with room-temperature H2, which is a gasoline. Because of this, vitality density is considerably greater, whereas smaller tanks on the car can nonetheless yield larger vary than is feasible than gaseous hydrogen. That area financial savings and increase in vitality density let the truck haul an even bigger payload.
At specially-equipped liquid hydrogen filling stations in Wörth am Rhein and within the Duisburg space, cryogenic liquid hydrogen cooled to minus 253 levels Celsius may be pumped into two 44-kilogram stainless-steel tanks mounted on both aspect of a GenH2 semi’s chassis. Refueling may be accomplished inside 10 to fifteen minutes. In response to the corporate, high-efficiency insulation on the tanks preserve the hydrogen under its ultra-low boiling level with out lively cooling.
“We’re additionally proud to be offering Daimler Truck with a few of the essential refueling infrastructure and hydrogen as a part of the trials,” says Caroline Stancell, Normal Supervisor (Europe and Africa area) of the Hydrogen for Mobility division at Air Products, a U.S.-based industrial gasoline provider taking part within the undertaking. “Our newest cell fueling station for liquid hydrogen shall be used for the undertaking within the Duisburg space and might due to this fact function below actual situations.”
Daimler Truck’s Subsequent Steps
Because it has carried out up to now with security applied sciences it has spearheaded, Daimler has made the recipe for liquid hydrogen (LH2) publicly out there. It’s now an ISO standard. What’s extra, the automaker plans to work immediately with different corporations to assist them develop their very own liquid hydrogen refueling and gas cell car applied sciences. The intention, Daimler stated in a press launch, is to “set up a worldwide mass marketplace for the brand new refueling course of.”
Daimler Truck is already at work with Linde on one other new course of for dealing with hydrogen cooled to the tremendous low temperatures at which it takes the type of a liquid. The automaker says that course of will yield even greater storage (and thus vitality) density with simpler refueling in contrast with the LH2 course of.
Daimler is laying the groundwork for making hydrogen a extra broadly out there automotive vitality modality. The corporate says additionally it is planning to work along with Shell, BP, and TotalEnergies to construct out hydrogen refueling infrastructure for main transport routes in Europe.
Pricing particulars on the GenH2 Truck had been unavailable at presstime. For comparability, Fleet Proprietor journal estimates a Nikola fuel-cell semi prices roughly $750,000—though Fleet Proprietor provides that incentives from the U.S. Inflation Reduction Act and California HVIP grants might, for some house owners, reduce the fee again by $40,000 and $288,000, respectively.
