UK and China Partner on EV Battery Swap Stations for Trucks

Electric trucks are about to get a game-changing upgrade that could finally make them cheaper and more practical than diesel rigs.

Octopus Energy, the UK's largest energy provider, has partnered with CATL, the world's biggest battery maker, to build battery swap stations across Europe starting in 2027. The joint venture, called Swaptopus, will focus on keeping electric trucks rolling by replacing drained batteries with fully charged ones in just minutes.

The concept is simple but powerful. Instead of waiting hours for charging or worrying about range, truck drivers can pull into a swap station and get fresh batteries faster than filling a diesel tank. Each hub will service thousands of trucks daily, creating a reliable network that makes long-haul electric trucking genuinely viable.

Battery swapping isn't new. The technology has thrived in Asia for years, with companies like Nio offering consumer car swaps and Gogoro running massive scooter networks across Taiwan. In 2025, CATL partnered with oil giant Sinopec to blanket China with swap stations. But Western companies largely abandoned the idea after Tesla tried and failed a decade ago.

Trucking makes perfect sense for the comeback. Heavy vehicles need enormous batteries to carry their loads, creating a weight spiral where more batteries mean more weight, which requires even more batteries. This makes hydrogen fuel cells look attractive for big rigs. But smaller batteries combined with guaranteed swap access changes the math entirely.

The Ripple Effect

The benefits extend beyond trucking. William Rowe, CEO of Swaptopus, says swap stations will charge batteries when renewable energy is abundant and the grid needs storage. Those thousands of idle batteries essentially create small power plants that can feed electricity back to communities during peak demand.

That flexibility could accelerate renewable energy adoption across Europe. When solar panels produce excess power at midday or wind turbines spin hard at night, swap stations can soak up that clean energy and redistribute it later.

The first UK mega hubs open in 2027. Success depends on convincing trucking companies to trust the infrastructure, but with two industry giants backing the network, the foundation looks solid.

Clean trucks that cost less to run than diesel aren't a distant dream anymore.
