Possible applications of hydrogen fuel cells in rescue and disaster operations

• Mobile emergency power supply: Rescue and disaster operations often require mobile units that operate away from the regular power infrastructure. Fuel cell generators can provide an uninterrupted and emission-free power supply for communication centers, field hospitals, lighting systems and other critical equipment. Compared to diesel generators, which are heavy and noisy, fuel cells operate quietly and emit no pollutants. This is particularly advantageous in dense urban or enclosed environments.
• Camp and field hospitals: When setting up temporary facilities such as field hospitals or emergency shelters, a stable and clean energy source is essential. Fuel cells provide a constant and emission-free power supply for medical equipment, ventilation systems and IT infrastructure without degrading air quality through diesel exhaust or having to run noisy engines in close proximity to patients.
• Communication and emergency centers: In the event of a disaster, communications infrastructure is crucial. Stationary and mobile radio and communication centers require an uninterruptible power supply that functions reliably even under difficult conditions. Fuel cells can provide a self-sufficient source of energy here, as they generate electricity continuously as long as hydrogen is available.
• Long-term energy autonomy in remote areas: In remote or hard-to-reach disaster areas that are not connected to the power grid, aid organizations or civil defense units often have to work self-sufficiently for days or even weeks. Fuel cell generators offer a sustainable source of energy that can be operated over long periods of time without having to rely on large diesel supplies.

Emission-free and environmentally friendly energy
A major advantage of hydrogen fuel cells is their emission-free power generation. In contrast to diesel generators, which emit CO₂, nitrogen oxides and particulate matter, fuel cells only produce water and heat as by-products. This is particularly advantageous in densely populated or heavily polluted environments where air pollution poses a health risk. In addition, fuel cells do not contribute to noise pollution as they operate almost silently.

High operating efficiency and flexibility
Fuel cell generators are extremely efficient as they generate electricity through a direct electrochemical reaction and have no thermal losses through combustion. This results in lower fuel consumption compared to diesel generators. In addition, fuel cell systems are modular and scalable, which means that they can be flexibly adapted to different power requirements. Whether for smaller task forces or larger mobile operations – the power can be adapted to the respective requirements.

Quiet operation and better operational capability in critical situations
In rescue operations, especially at night or in clandestine operations, the noise level is a decisive factor. Diesel generators are not only loud, but also susceptible to vibrations that can hinder the use of sensitive equipment. Fuel cells, on the other hand, operate almost silently and can therefore be used inconspicuously and without disturbing the surroundings. This is not only a great advantage in urban disaster areas, but also in military and clandestine rescue operations.

Longer operating time compared to battery storage solutions
Battery storage solutions have the advantage of being emission-free and a quick and easy way to supply energy in certain applications. However, they have considerable limitations in disaster situations: The capacity of battery storage systems is limited and they need to be recharged after a certain period of use. Particularly in remote areas or in situations where a continuous energy supply is required, battery storage systems cannot compete with the continuous output of a fuel cell generator. As long as hydrogen is available, a fuel cell can provide uninterrupted power.

Longer fuel life compared to diesel
Another advantage of hydrogen fuel cells over diesel generators is the durability of the fuel. Diesel is susceptible to ageing and microbial infestation (known as diesel pest), which can degrade its quality over time. This can lead to problems with power generation, especially when used in remote or extreme environments where the fuel is stored for long periods. Hydrogen, on the other hand, is stable and does not lose quality over time. This makes it particularly suitable for emergency situations where fuel needs to be stored for longer periods.

Challenges and solutions
Although hydrogen fuel cells offer clear advantages in their application for rescue and disaster operations, there are also challenges that need to be overcome. These include, above all, the infrastructure for supplying hydrogen. While diesel generators can rely on established logistics, the supply of hydrogen is still being developed in many regions. Nevertheless, the expansion of hydrogen filling stations and supply chains is progressing steadily, and mobile hydrogen supply systems already offer flexible solutions for use in remote areas.

The procurement of hydrogen for applications like PowerUP is generally unproblematic, as there is a wide availability of suppliers for technical gases across Europe. These suppliers ensure that hydrogen is provided in various purity levels and quantities for industrial, commercial, or private use.

Another challenge is the initial investment. Fuel cell systems are currently still more expensive than diesel generators or battery storage solutions. However, prices are falling due to technological advances and increasing demand, and long-term operating costs are often significantly lower as hydrogen is cheaper and fuel cells require less maintenance.
