Energy and Transportation

Energy and Transportation

Transportation and energy sectors face a common concern: electricity storage.


Renewable energies are intermittent. Their development and stringent laws make the storage of produced electricity a fast-growing market.


By implementing more and more “zero emission” zones, the cities actually promote electric vehicles. Therefore, autonomy and recharging time become crucial challenges.

To accomplish this challenge, our engineers design innovative technologies for your organization, in 3 domains:

Thermal management to improve their efficiency and life span

Fuel cells

Fuel cell integration for mobility or energy production


Production and storage into liquid organic hydrogen carriers


Thanks to 10 year experience in Rankine systems, Exoès provides your organization with its thermal management know-how.

According to the Boston Consulting Group, energy storage will reach €26 billion turnover in 2030. Batteries (for stationary and mobile applications) will represent more than 50% of this market. Industrial companies face a tremendous challenge.

By delegating your battery thermal management, you have the certainty to obtain:

  • A considerably shortened recharging or discharging time.
  • An improved efficiency
  • An increased power density.

We work with every type of battery as well as stationary or mobile applications.

Stationary application:
battery containers

The context

The electricity surplus storage into containers.

The issue

To satisfy peak demand.

Mobile application :

The context

Increased sales of hydrid vehicles.

The issue

Satisfaire To satisfy end customers.

Exoès answer

By providing thermal management for batteries or battery containers, Exoès optimizes recharging/discharging time and improves battery autonomy.
As a result, your product life span and efficiency are increased and your organization gets a real competitive advantage. .

Fuel cells

Exoès managers have one conviction: tomorrow’s “zero emission” vehicle will be equipped with a fuel cell which will power a significantly reduced battery.

Indeed, the unique use of batteries in transportation would raise 2 issues: their autonomy and the natural resources needed for their production.

On start-up, the vehicle is fully fuelled by the battery. A few moments later, hydrogen cell supplies enough energy for the vehicle propulsion, lighting, cooling or heating, braking systems…. During acceleration, fuel cell and battery powered the vehicle together.

Exoès provides battery and fuel cell makers with its skills in system integration and thermal management.

A battery powered with a hydrogen cell resolves all the difficulties above:

The fuel-cell is a range extender: it fuels the battery with all the energy necessary for the electric engine propulsion, air conditioning or braking systems, lighting… As a result, the vehicle is more efficient.

The battery pack is reduced: charging time is shortened and it production needs less rare metals.
The fuel cell works with a tank full of hydrogen.. Produced via renewable energies, it is inexhaustible and doesn’t emit any CO2.

By coupling a battery to a fuel cell, manufacturers fully answer end customer requirements. This hybrid electric car is “zero emission”. Moreover, its autonomy and charging time are similar to vehicles equipped with thermal engines.

Exoès research on fuel cells can be applied to the energy sector.

Hydrogen production and storage

With regards to sustainable development, hydrogen appears to be a clean energy: a fuel cell only emits water. On the contrary, a thermal vehicle emits CO2, fine particles, nitrogen oxides, and unburned hydrocarbons which are responsible for greenhouse gases and air pollution.

Nevertheless, there are still many barriers to cross before hydrogen can be widely introduced. The deployment of vehicles equipped with fuel cells have to be related to the development of hydrogen stations. Setting up such infrastructures is very expensive.

That’s the reason why Exoès studies production and storage technologies in pressurized hydrogenated liquids at room temperature as well as the associate reformers. We offer your organization the following skills to develop your storage project according to your particular specifications:
  • Simulation, dimensioning tolelerancing
  • Material selection
  • Design

Working on the transportation sector will bring new opportunities on energy production and storage.
