Fleet managers


At Symbio, we are increasing the operational flexibility and autonomy of our zero emissions vehicles, already renowned for their ease of use.

The challenges

The need to reduce pollution and greenhouse gases in urban environments is having a double impact on fleet managers :


– towns and cities are increasingly restricting access to vehicles to their centres through a range of different measures (urban tolls, ultra-low emissions zones, etc.)
– local authorities are placing increasingly stringent demands on service providers (cleansing, waste management, public transport networks, deliveries, etc.) with regards to the environmental impact of the vehicles they use, particularly when they are working on behalf of public services.
As far as the latter are concerned, the plan is to switch to zero-emissions vehicles, all the while reducing the impact of this transition period on operations and costs.

Thanks to the hydrogen battery system and the related services put forward by Symbio, fleet managers are finally able to convert all of their vehicles to zero-emissions vehicles without being required to overhaul their operational structure.

In choosing Symbio, they benefit a few options.


Limited operational constraints

– Real autonomy is at least double that of equivalent battery only vehicles, irrespective of the weather conditions – when the vehicle is moving, the extra energy stored in the form of compressed hydrogen is transformed into electricity via the Symbio hydrogen battery technology. This autonomy extension also allows employees to return home with their zero-emissions service vehicles, without having to connect them to the network overnight.

– A wide range of back-ups and equipment can be used (calorimeter box with cold unit, electrical socket, lifting platform, etc.) on board the vehicle, without in any way affecting its autonomy. With Symbio, zero-emissions is now within reach for delivery companies, even those with the most demanding energy requirements (transporting medication, blood/organs, perishable goods, etc.).

– The charging time is less than 5 minutes at the hydrogen station, for a capacity equivalent to 8 hours of slow charge on an electrical network.

Comfort of use

– The heating can be switched on in winter without this having any impact on the vehicle’s autonomy.

– All of the benefits of driving an electric vehicle are retained (silent driving, no vibrations, no repeated speed changes, etc.).

Zero emissions

– Vehicles equipped with Symbio solutions do not emit any pollutant particles or greenhouse gases from their exhaust pipes. They only emit water vapour.


– An example of this can be found in the enhanced autonomy exhibited following Symbio hydrogen batteries being incorporated into Renault Kangoo ZE models.

A competitive economic equation

– The total cost of owning electric vehicles equipped by Symbio is basically the same as that of owning battery-operated electric vehicles, in part because fleet managers are able to reduce costs involved in installing terminals at their depots or agencies.

– The marginal extra expense has to be put into perspective with regards to benefits such as zero-emissions and ease of use.

– It should be noted that light utility vehicles equipped by Symbio travel partly using electric power – the mix can rise to 70% electric and 30% hydrogen. Given the low price of electricity (€0.10/kWh), this helps reduce the overall cost of the energy used.

A range of digital services

– Vehicle information in real-time: fleet managers have customised access to the web portal mysymbiofleet.com, where they are able to view near real-time information on remaining autonomy, the level gauges for the battery and hydrogen, the distance travelled each day, visits to hydrogen recharge stations and recharge times on the electrical network (for plug-in hydrogen vehicles). This allow fleet managers to optimise the way in which the energy needs of their fleets are managed.

– Easier access to stations: via the MySymbioRech2rge application, drivers have no need for either a badge or an electronic lock to access stations and to pay quickly and easily. This application – only available in France for the time being – also allows you to access real-time information on station availability (conditional on compatibility).

A large after-sales network

– Symbio can carry out remote maintenance on all vehicles in order to deal with any technical issues (“level 2”) and to make repairs.

– Maintenance, repairs and everything covered by the warranty will be managed through our network of garages.

70% of the first and last kilometres covered using low or extremely low emissions vehicles by 2025: this is the target in France set by the world’s leader in express international transport. Faced with the intrinsic limits of battery-operated vehicles – particularly with regards to autonomy and recharge times – it became clear that looking into hydrogen solutions was the right path to follow.


A first delivery vehicle equipped with the Symbio hydrogen battery solution was acquired by DHL Express in Lyon in 2015 as part of a regional project supported by the EU known as the Hyway project, which also aims to implement recharge stations. Two years later, Geoffrey Dimelo, head of the agency, is extremely satisfied: “There’s no way we would have been able to cover so many kilometres with battery only electric vehicles, particularly during winter when drivers have to switch the heating on. Of course, building new stations will make delivery journeys easier, but the Auvergne Rhône-Alpes region has an ambitious deployment plan (the Zéro Emission Valley project).”


Geoffrey Dimelo, who can’t wait to extend their range of hydrogen vehicles in the quest for higher volumes, is convinced with regards to the suitability of hydrogen transport for city centre deliveries: “With our vehicles equipped with Symbio range extenders, we are aiming to anticipate the likely growth of restricted access areas in city centres”, he explains, “whether today in cities like Grenoble or Paris, or in the future in towns and cities across France”.
