Electric HGVs in the fast lane to overtake hydrogen trucks

Hydrogen-powered heavy lorries were once seen as the future of emissions-free road transport but they could soon be relegated to niche markets in Europe. Electric trucks are now the vehicles roaring - or rather purring - into a greener, cleaner world. 

On the outskirts of Trondheim in western Norway, food wholesaler Asko has been testing four hydrogen fuel cell trucks since 2020 supplied by Swedish truckmaker Scania.

The experience has been mixed so far. Integration problems, defective parts and a forced stoppage after the explosion of a charging station near Oslo have meant the vehicles have only been available for use 40 percent of the time.

"They're not on the road as much as we would have liked. That's the least we can say," admits Asko project head Roger Saether. "But we're convinced that it will all work out in the end."

When they're running, the trucks, which have a range of up to 500 kilometers, supply supermarkets spread across a vast region. For closer deliveries, the group uses battery-run vehicles, which today have a shorter range.

That distribution of roles - hydrogen lorries for heavy loads over long distances, electric ones for lighter loads on short distances - has long been accepted as standard among industry experts due to the advantages and disadvantages of each technology.

But things are changing.

"Now what we're seeing is that contrary to a few years ago, electric trucks and buses are actually playing an increasingly big role and we also see a very important role for them to play in the decarbonization process," said Fedor Unterlohner, freight manager at the NGO Transport and Environment.

Electric future

Heavy duty vehicles account for six percent of the EU's greenhouse gas emissions. Brussels has called for the industry to reduce its emissions by 45 percent compared to 2019 levels by 2030, and by 90 percent by 2040.

According to a study conducted last year by German authorities, truckmakers expect 63 percent of new lorries sold in Europe in 2030 to be "zero emission" vehicles. Electric trucks are expected to make up the lion's share, with 85 percent. 

That's because previous concerns about electric trucks have been eliminated as, unlike hydrogen, the technology for electric trucks has benefited from advances made in the electric car industry.

 

Getting charged up

Most heavy trucks in Europe drive fewer than 800 kilometers a day, a distance that could soon be within reach of electric batteries - especially given drivers' strictly regulated breaks, which would allow time to recharge their vehicles.

The amount of energy batteries can store continues to improve, to the point where the weight difference compared to a diesel truck is expected to become insignificant. So-called megawatt charging stations are currently being developed and should soon be able to provide 10 times more power than the fastest charging stations currently available.

Low maintenance

When it comes to cost - a crucial factor, given the narrow margins in the transport sector - electric trucks hold the advantage. Purchase prices benefit from economies of scale generated by the rapid development of electric car batteries.

Operating costs are also modest, with e-trucks requiring little maintenance and electricity normally much less expensive than green hydrogen. However, in some cases hydrogen lorries could be the wiser choice, if for example, there are two drivers in Europe where drivers are allowed to skip regulated breaks.

But even Scania, which has supplied the four hydrogen trucks to Asko, has chosen to focus on electric heavy trucks due to lower costs in "total operation economy and fuel efficiency."
