Climate change: electric trucks can 'compete with diesels'


A new study by scientists challenges established beliefs that electric trucks cannot compete with heavy-duty diesel-powered trucks.

A new study by scientists challenges established beliefs that electric trucks cannot compete with heavy-duty diesel-powered trucks.

Until now, it was thought that the batteries required to provide these trucks with a long range would create a huge cost.

But researchers have shown that installing fast charging stations on the roads instead of putting large batteries in trucks will make electric trucks more advantageous over diesels.

The popularity of electric vehicles has been increasing in the world recently.

In the united kingdom Mart in the month of car Electric or plug-in hybrid vehicles accounted for 14 percent of its sales.

One of the regions where the most electric vehicles are sold per person West Europe700 thousand electric vehicles were sold in 2020.

But the situation is different in freight transport.

This is also an important issue for climate change. It is estimated that 7 percent of global carbon emissions are emitted by trucks.

Although Tesla and other manufacturers tried to enter this sector with small steps, many experts were of the opinion that these vehicles could not compete with diesel vehicles in terms of cost.

According to this view, the cost of extra batteries to be added for the longer range makes financially profitable impossible.

But a new study by the Stockholm Environment Institute (SEI) suggests the issue is being viewed from the wrong angle.

SEI researchers say that common and fast charging stations instead of larger batteries will give electric trucks an advantage over diesels.

“When we look at the average numbers, we have come to the point where this makes sense,” says Björn Nykvist, who is part of the team of the research published in Joule magazine.

“The size of the battery in the truck is not that important. It just needs to be fast enough for the charger.

“The main thing here is that heavy vehicles consume more energy. The more energy a vehicle consumes, being an electric vehicle makes it more economical in the same place. For example, a heavy truck consumes more diesel than a light truck, but this is why it is an electric vehicle. makes it more profitable to be a vehicle. “

In the model they developed, the researchers assumed that a truck would charge for 40 minutes after traveling 4.5 hours.

Since the majority of trucks make most of their journeys on highways, ports and terminals, the fast charging stations needed will be significantly less than the charging stations needed by cars in much wider variety of locations.

The only problem here is that such charging station technology is not yet available. But researchers are of the opinion that the technology will reach this point quickly.

Experts recommend that governments concerned about climate change give incentives in this area.

Dr. “It would be a good starting point for the government to support people who want to buy these vehicles,” says Heikki Liimatainen.

“But I think if a subsidy is to be given, it should be given to setting up fast charging station networks on highways.”

Big truck manufacturers also say that the transition to electric trucks will depend on fast charging stations on important routes.

“The potential to decarbonise road transport is enormous,” says Lars Martensson, Director of Environment and Innovation, Volvo Trucks.

“But for this, fast charging station infrastructure is important and governments need to give incentives to install these stations at critical points, especially warehouses and logistics centers.”

Although there are those who oppose the use of electric trucks, there are also those who say that hydrogen-powered trucks can be used to transport the heaviest loads.

Dr. “The most important thing here is the price of the hydrogen fuel cell. These prices are in a downward trend, but they are not falling as fast as the battery prices.
