Project brief

Despite considerable support for the hydrogen mobility sector, there remains low take-up of fuel cell electric vehicles (FCEVs) and vehicle sales remain low. This is a significant issue for the commercialisation of the sector, as whilst sales volumes are low, vehicle production costs and prices remain high. The lack of demand for hydrogen also damages the business case for investment in early hydrogen refuelling stations (HRS).

This project is the next step in a major pan-European effort to support commercialisation of hydrogen mobility.


ZEFER started in September 2017 and will run until September 2022. The project will deploy 180 FCEVs (Fuel Cell Electric Vehicles) in Paris and Copenhagen (60 vehicle taxi fleets), and London (50 private hire vehicles and 10 deployed to Metropolitan Police fleets).

Vehicles will each complete at least 40,000km, totalling over 1 million km between them, and more than 100 tonnes of hydrogen will be dispensed.

These applications mean that vehicle performance will be tested to the limit, allowing a demonstration of the technical readiness of new generation FCEVs for high usage applications.


ZEFER will demonstrate viable business cases for captive fleets of FCEVs in operations which can realise value from hydrogen vehicles, for example by intensive use of vehicles and HRS, or by avoiding pollution charges in city centres.

Driver attitudes to FCEVs will be assessed to understand changes in attitudes, lessons learned and the impact of the trial, and any barriers to widespread adoption will be identified.
