Fuel cells
Selection and integration of fuel cell modules tailored to vehicle requirements, operating profile and project assumptions.
Hydrogen drive integration for vehicles and working machines
We provide support in the design and integration of hydrogen drive systems for utility and specialist vehicles. Our services cover the entire process — from concept and component selection to building a complete drive system and integrating it with an existing vehicle.

Ennovation Technology supports clients in the design and integration of hydrogen systems, combining expertise in automotive, electric drives, battery systems and software.
With hydrogen drive systems, clients gain:
- Zero-emission vehicle operation.
- Short refuelling time compared with conventional charging.
- The ability to achieve the required vehicle range.
- A modern and innovative fleet of the future.
What do we integrate?
We build complete drive systems by combining mechanical, electrical, hydrogen and control components into one functional and safe system.
HV battery systems
Design and integration of batteries supporting the operation of the hydrogen system and electric drive.
Electric drive
Selection of the electric motor, integrated gearbox and drive system components.
Vehicle controllers
Design of dedicated controllers enabling management of the entire drive system.
Software and control
Control algorithms tailored to the specific vehicle, components and client requirements.
What does cooperation look like in hydrogen projects?
We focus on a comprehensive approach and partnership-based cooperation, which is why we tailor our projects to clients’ individual needs — not the other way around. In hydrogen projects, we guide the client through five main areas of cooperation.
01
Needs analysis and preliminary design
We begin the process with a client consultation. Based on this, our engineering team prepares an individual design tailored to the specific vehicle and its intended use. The design includes the placement of all necessary hydrogen system components.
02
Component selection and delivery
Based on the project assumptions, we are responsible for selecting and delivering all required elements, such as fuel cell modules, compressed hydrogen storage system, battery system, electric motor, integrated gearbox and others. Components are selected within the assumed budget.
03
Quotation and approval
Before starting the work, we present a detailed project quotation covering both component costs and the integration service.
04
Mechanical and electrical integration
We carry out the full scope of mechanical and electrical work related to the installation of the drive system. We combine all components into a functional and safe system.
05
Software and control
We design dedicated vehicle controllers that enable efficient management of the entire drive system. The controllers are tailored to the specific vehicle and client requirements.

How does Ennovation ensure the safety of the hydrogen system and prevent leaks?
Our company places a strong emphasis on the safety of the hydrogen system at every stage of vehicle design and integration. To minimize the risk of leaks, high-quality hydrogen system connections and appropriate sealings are used already at the design stage.
Are hydrogen sensors installed in Ennovation vehicles, and how do they enhance vehicle safety?
Hydrogen sensors are a crucial part of the safety system in hydrogen-powered vehicles. Their primary function is to detect potential gas leaks as early as possible. In vehicles designed by Ennovation, sensors are placed in critical areas, such as beneath the driver’s cabin and near the fuel cell module. This strategic placement allows for quick detection of threats and immediate system response, significantly increasing safety for both the user and the vehicle.
How are the batteries cooled, and how does this affect their lifespan?
The batteries are equipped with a liquid cooling system that maintains optimal operating conditions for the lithium-ion cells. Cooling prevents overheating of the cells, which improves performance and extends their lifespan.
Does the battery system for hydrogen drives meet safety standards?
Yes. The systems we design include an advanced Battery Management System (BMS) that monitors cell operation and detects conditions such as thermal runaway and thermal propagation. These functions comply with the UN ECE R100.03 type approval requirements, ensuring a high level of safety.
What is the hydrogen storage system in the Ennovum H670 tractor made of?
The system consists of four Type IV tanks, constructed with an inner layer of HDPE (High-Density Polyethylene) reinforced with a carbon fiber composite. The tanks are located behind the driver’s cabin and operate at a nominal pressure of 700 bar.
What safety features do the hydrogen tanks have?
Each tank is equipped with an OTV (On-Tank Valve), which allows for refueling, supplying hydrogen to the fuel cells, and safely venting the gas in emergency situations. Additionally, thermal protection devices (TPRDs) are used to release hydrogen in case of excessive temperature rise.
