Hyundai has delivered the first seven hydrogen-powered trucks to customers in Switzerland, out of a total order of 50.
Hydrogen-powered trucks have a longer range than electric variants, but cost more to build.
However, the relative efficiency of the power source and the longer life of the vehicles will mean that there will be cost parity with diesel trucks by 2030, according to a McKinsey study published at the start of this year.
A new hydrogen infrastructure will enable Migros, the Swiss supermarket chain, to move goods from depot to store. Migros is leasing the trucks from Hyundai Hydrogen.
Hyundai is aiming to make the trucks a regular sight on Swiss roads, with a planned fleet of 1,600 by 2025.
In Europe, the company is also aiming for Austria, Germany, the Netherlands and Norway.
