3 reasons why batteries will power our future trucks, not hydrogen fuel cells

A prominent decarbonization researcher believes battery electric trucks will become the norm for low emissions road freight, as alternatives, like fuel cell vehicles, are more expensive to run.

In an interview with Clean Energy Wire, Auke Hoekstra, an academic researcher from Eindhoven University of Technology, says that fuel cell vehicles “won’t ever be able to compete with electric trucks‘ business case.”

Below are three of the key arguments he makes for why battery electric trucks will become the norm, leaving fuel cell vehicles as a distant concept of a bygone moment.

Battery technology is nearly ready

As he alludes, around 80% of trucks, in the Netherlands at least, travel 750 km (470 miles) per day, at the very most. If you want to haul goods further than this, it starts to get expensive quickly as you’ll need to employ more drivers, and pay overtime.

In reality, most trucks only need to be able to drive 750 km each day. With recent news that Tesla‘s Semi is aiming for a peak range of 1,000 km, it seems the technology is close to where it needs to be for low emission haulage.

Infrastructure is simpler and cheaper

What’s more, the vast majority of truckers these days don’t lead the romanticized lifestyle that Hollywood perhaps suggests. They’re not out on the road for weeks at a time, but perform a few trips per day ferrying goods between ports and distribution terminals, where packages are sorted and moved onto smaller vans for final distribution.

This means that most trucks spend their nights not out on the road, but at distribution centers being packed ready for the morning shift. In other words, it’s the perfect time to recharge the vehicle.

It all seems painfully simple, and it is. Switching to electric trucks requires little change to infrastructure. Assuming the wagons have enough range to complete their entire day’s journey, haulage companies only need to buy some fast chargers for their depots, and upgrade their fleet of trucks.

For fuel cell trucks to work, there needs to be vast changes to national fueling infrastructure, depots will also need to invest great sums into their own fueling hardware.

Battery trucks are easier to design

Moving away from infrastructure-based arguments for a moment, switching to battery electricity trucks offers engineers new, and beneficial, design opportunities.

It’s quite common for electric vehicles to be quite a bit heavier than their petrol or diesel counterparts. This isn’t necessarily the case with haulage trucks.

According to Hoekstra, designing an electric truck from the ground up can save weight — about three tonnes, in fact.
