CATL Partners with Octopus Energy to Enter European Electric Truck Battery Swap Market
0xBroomberg
CATL and Britain's largest home energy supplier Octopus Energy have formed a joint venture to build an electric truck battery-swap network across Europe, targeting over 30 swap hubs serving more than 300,000 trucks by 2035, with the first stations going live in the UK next year.
What exactly is this partnership building?
The two companies formed a joint venture to deploy electric truck battery-swap stations across Europe — a truck drives in, the entire battery pack is swapped in five minutes, faster than refuelling with diesel.
The first stations land in the UK next year, with a target of over 30 swap hubs covering more than 300,000 electric trucks by 2035.
The project is expected to mobilise over £30 billion in private investment. This means → CATL is not just selling batteries — it is exporting a full "swap-as-a-service" business model to Europe.
Why is swapping better than fast charging?
CATL's head of overseas investment, Oscar Luo, said the swap system replaces a 500+ kWh battery pack in under five minutes; ultra-fast charging still takes roughly one hour.
In plain terms = charging is "waiting for the battery to slowly drink its fill"; swapping is "handing over a full tank on the spot" — for a long-haul truck, one hour versus five minutes is a completely different cost equation.
The swap model also means fleet operators never own the battery, cutting the upfront truck price while extending battery life and simplifying recycling.
Can the economics beat diesel?
Octopus Energy founder Greg Jackson said: "With today's swap technology, our costs are already below current diesel prices."
He added that even if diesel prices fall back, swap costs will roughly match — and "unlike diesel, our costs keep falling every year."
This reflects a tailwind from the Middle East conflict pushing diesel prices higher, which has accelerated European heavy-truck operators' interest in electric alternatives — the swap business case is easiest to make when fuel costs are elevated.
Where does European heavy-truck electrification stand today?
In Q1 2026, electric trucks held just 0.9% market share in the UK and 4.4% across Europe — far behind passenger-car electrification.
The main constraints are regulatory pressure and insufficient infrastructure. This means → if the swap network can scale, it addresses precisely the biggest bottleneck: nowhere to recharge.
In plain terms = low share signals both a late start and large headroom — provided the infrastructure keeps pace.
Can China's playbook be replicated in Europe?
Battery swapping was first commercialised by NIO (蔚来) and is now widely deployed in China; CATL plans to complete 900 truck swap stations in China this year, up from roughly 305 last year.
CATL has pledged to cover 80% of China's major logistics corridors by 2030; Beijing's target is 1.6 million electric trucks on the road by then, with EVs reaching 40% of new truck sales.
But overseas, swapping has expanded slowly due to high station-build costs. This means → whether China's scale advantage can transfer to Europe hinges on the joint venture driving per-station costs down — and that is the central question this partnership must answer.
