Myth 1: Hydrogen is dangerous and “explodes easily”
Hydrogen is flammable, but it is not more hazardous than gasoline, diesel, or natural gas – it’s just different. It is very light, disperses quickly upwards in the event of leaks, and only forms dangerous concentrations in small, poorly ventilated areas. Modern systems are fitted with pressure regulators, safety valves, sensors, and emergency shut-off mechanisms. The risk mainly lies in improper handling – not in the substance itself.

Myth 2: Hydrogen is a new and untested technology
Hydrogen technology has been around for over 150 years – it is routinely utilized in aerospace and industrial processes (e.g., ammonia production, metal processing). The only new aspect is the decentralized, mobile, and green utilization in energy supply and transportation.

Myth 3: Hydrogen is too unstable to be stored safely
Storage methods have been long perfected. High-pressure tanks (200–700 bar) are rigorously tested, crash-proof, and equipped with safety valves. Alternatively, there are liquid or chemically-bound storage options (e.g., metal hydrides). The safety level is on par with or better than that of natural gas.

Myth 4: Hydrogen is too costly and inefficient
The efficiency of hydrogen systems is lower than that of pure electricity, but they offer long runtimes, high energy density, and emissions-free operation. Costs are continually declining due to technological advancements and larger production scales. In scenarios where batteries are impractical (e.g., long-term storage, heavy-duty applications, emergency power, industry), hydrogen is economically viable.

Myth 5: Hydrogen is not truly environmentally friendly
This is only partially correct – it relies on the method of production. For sustainable use, transitioning to green hydrogen is essential.

• “Gray” H₂ from natural gas generates CO₂ emissions.
• “Blue” H₂ captures CO₂ through capture and storage technologies.
• “Green” H₂ is produced from renewable electricity through electrolysis – CO₂-free.

Myth 6: Hydrogen burns invisibly, making it more dangerous
It is true that the flame of hydrogen is pale blue and nearly invisible – but it is cooler than, for instance, a gasoline flame.
Visible or infrared flame detectors are employed to reliably identify fires. In professional settings, sensors and alarm systems are standardized.

Myth 7: Hydrogen can explode like a bomb
An explosion necessitates confined, stoichiometric gas-air mixtures and ignition sources – in an open setting, this is nearly impossible. In modern systems, hydrogen is carefully controlled, monitored, and vented promptly in case of overpressure. The risk of an explosion is significantly lower than commonly believed.

Myth 8: Hydrogen vehicles or generators are noisier or more complicated
The opposite is true. Fuel cells are quiet, low-vibration, and largely maintenance-free. While the technology requires training in handling high-pressure systems, it is very straightforward to operate.

Myth 9: Hydrogen diffuses freely and cannot be managed
Hydrogen is the smallest molecule and can indeed diffuse through certain materials, but modern seals, valves, and composites are designed to accommodate this. In practice, there are no safety-relevant losses.

Myth 10: Hydrogen will never have a role in the energy system
The global expansion demonstrates otherwise: industries, shipping, rail, aviation, emergency power systems, and energy storage are increasingly relying on hydrogen. It is not a substitute for electricity, but an enhancement where batteries or grids reach their limitations.
