Trucks powered by hydrogen cells are a actuality in many tasks by main producers.

Volvo started working trucks with this know-how in June, the identical month Daimler started testing its second mannequin of the sort. But these aren’t the one firms which are in the know-how, as a result of using cells is best than standard batteries.

UOL Car sought out a hydrologist to clear some doubts. The principal purpose is that some producers want to decide on hydrogen in industrial automobiles even earlier than it has a spot in vehicles – aside from lights that solely make heavy automobiles.

“It’s not that including extra weight to a pick-up, for instance. After 20 years of growth, engineers have come to the conclusion that extra the automobile, the better benefit for the automobiles operated by the petrol station in: autonomy. (identical as a traditional automobile), filling time (from 3 to five minutes ) and value”, explains Monica Saraiva Panik, Hydrogen Instructor at SAE Brasil. When it involves advertising and marketing, the outdated saying “time is cash” is all the time higher.

How a fuel cell works

Here’s a short rationalization of how the system works: the incoming hydrogen is saved below stress in a tank and goes to the fuel tank. It mixes with oxygen earlier than going by the reactor, creating an electrical present, in addition to sending solely pure water into the tube. No extra driving a diesel truck and respiratory that “smoke”. All the vitality is saved in the batteries and despatched to the electrical motor.

Not everyone seems to be in the pattern class. Hyundai is a type of that has already put fashions of the sort on sale. Launched in 2020, the XCIENT Fuel Cell has been extensively examined. The first commercially launched hydrogen truck started testing with 47 items in Switzerland. According to the producer, the mannequin has exceeded 4 million kilometers in July this 12 months.

Although distribution requires its personal services, the community is rising. It is probably not as quick as electrical charging stations, however the good thing about cell charging time is plain, not not like a diesel truck. The vary is greater than 400 km and the overall weight is greater than 40 tons.

Heavy responsibility electrical automobiles have many benefits. “A fuel electrical automobile produces its personal vitality from hydrogen. There is not any approach to fill automobiles with an influence above 200 kW solely with batteries, as a result of they should be provided with electrical energy exterior, the grid needs to be overloaded, and the batteries needs to be bigger. these automobiles needs to be very heavy, in addition to the battery utilizing dearer metals than the fuel cell system”, mentioned Monica.

“Battery know-how can be good, such because the discount of parts in comparison with hydrogen know-how, nevertheless it requires particular alloys and excessive extraction prices. Hydrogen, then again, requires an in depth distribution system to highways”, he concluded. Gerhard Ett , professor in the Chemical Engineering division at FEI and coordinator of Formula FEI H2..

Development is characterised by many connections. “Many automobile producers are engaged on this software. There are many collaborations, each for trucks and for bus manufacturing.

For instance, the German firm Daimler Truck has partnered with the Volvo Group, creating the Cellcentric Hydrogen Fuel Cells collaboration; German auto components firm Mahle and Canadian Ballard Power System, a standard fuel cell firm, signed an settlement for the joint growth of fuel cell methods; Another Canadian firm, Hydrogenics, acquired the American Cummins, an engine firm, and the French Air Liquide, a fuel firm.

Another Swedish big, Scania, has partnered with American Cummins and exports to Norway. In Brazil, we now have a very good instance, like Marcopolo – which is partnering with the Audace fuel cell mannequin in China”, says Gerhard.

If in the present day it’s nonetheless generally known as a producer of diesel engines, Cummins is without doubt one of the strongest firms. More than 20% of its shares are in the palms of Cummins, a Canadian firm Loop Energy believes that hydrogen heavy trucks are as highly effective as electrical trucks. According to an interview revealed by the Reuters information company, “this product provides the financial savings wanted for adoption in the present day,” mentioned Ben Nyland, CEO of Loop Energy.

The firm made a calculation primarily based on the value of diesel on the European continent. According to the research, it prices about US $1.91 per liter and hydrogen prices US $10 per kg. As dangerous because it sounds, these kilograms are extra productive than a liter of diesel. According to the research, a truck geared up with the model’s new cell system can journey 177 kilometers on 100 {dollars} of hydrogen, in comparison with 174 for its electrical counterpart.

When it involves weight, using cells is an actual benefit, in comparison with electrical and diesel opponents. “Comparing the lithium-ion battery financial institution of a 600 kWh Heavy Duty (truck), to run 1,360 kilometers would weigh 3,800 kilograms.

It will probably be changed by hydrogen and fuel cells, with a 350 kWh electrical motor that can eat roughly 7.5 kg per 100 km, and 102 kg for 1,360 km of autonomy. If the truck averages 2.62 km/l (at 100 km/h) for the aforementioned 1,360 km, a tank of about 520 liters of diesel is required, i.e. 5 occasions as a lot. in hydrogen”, says Gerhard.

There is plenty of pleasure about using fuel cells in all areas of automobiles, however they appear to be shifting shortly among the many heavyweights. Although the Toyota Mirai is in its second technology, the electrical market has grown quicker, and the time has come for trucks and buses.

According to Monica, California and Europe alone goal to have 100,000 hydrogen trucks by 2030. Like Mirai, the know-how will probably be distributed to smaller markets. Daimler intends to start out testing its truck with clients from subsequent 12 months, however serial manufacturing is scheduled for 2027. The objective of the automobile is carbon-free operation (tank to the wheel) to Europe, Japan and North America in 2039.
