Facts about hydrogen
- General facts
-
Under normal conditions, hydrogen exists as an H2 molecule, a colorless and odorless gas.
In the periodic table of the elements, it is the lightest element and thus ranks first.
Hydrogen is the most common element in the universe and a component of water and all living things.
- Technical data
-
Calorific value: 3 kWh/ Nm3 - 33,33 kW/kg
Density: 0.0899 kg/Nm3
Energy content of 1 Nm3 hydrogen corresponds to 0.34 l gasoline
1 kg hydrogen corresponds to 2.75 kg gasoline or about 2.1 kg natural gas --> Highest mass-related energy density
Hydrogen is:
non-explosive (in pure form), non-toxic, non-corrosive, non-spontaneously combustible, non-disintegrating, non-radioactive, non-foul-smelling, non-hazardous to water, non-carcinogenic
Hydrogen is about 14 times lighter than air and very volatile. This results in rapid mixing to non-hazardous concentrations with ambient air.
Burns with oxygen only to water.
- Areas of application
-
Hydrogen offers innumerable technological possibilities.
Electricity (and heat) generation | Use in fuel cells / power-pacs in the energy sector or in mobility | Energy storage | Material use in power-to-X | Process gas | Coolant | Fuel, and many more.
Due to its properties, green hydrogen plays the decisive role in the decarbonization of the energy sector, mobility and production. It is produced by the electrolysis of water. The electricity required for this comes from renewable sources.
- Energetic use
-
By means of hydrogen technology, not only extremely energy-intensive industrial processes, e.g. in steel production, can be supplied. Also our energy system, the chemical industry and mobility can effectively benefit from an energetic use.
The corresponding products can be found under hähn hydrogen fuel cell systems.
Due to its storage capacity and high specific energy density, large amounts of energy can be stored for months. By using renewable energies, this is the most climate-friendly method of energy storage on a large scale.
Hydrogen can also be used directly as an additive energy carrier in the conventional natural gas grid or converted back into electricity using fuel cell systems.
Countless opportunities arise from dual use across sectors. In the mobility sector, hähn hydrogen power pacs offer emission-free and noise-reduced drives in shipping, rail or heavy-duty transport and for work machines.
- Material use
-
In addition to the energetic possibilities, hydrogen holds innumerable potentials in a material processing.
hähn hydrogen offers a range of power-to-X (PtX) technologies for this purpose. Hydrogen is used as a synthesis gas in chemical production plants, for example to produce low-CO2 synthetic fuels or basic chemicals.
The plants available from hähn hydrogen include
- Haber-Bosch synthesis: ammonia production
- Fischer-Tropsch synthesis: gases, gasolines, kerosene, kerosenes
- Methanol synthesis: methanol as energy storage, higher energy density than H2 and storable in liquid state
- Hazard analysis
-
Hydrogen is not self-igniting. It is nevertheless classified as a hazardous substance, since an explosion can occur at a certain mixing ratio with air and, for example, a spark (oxyhydrogen reaction).
However, hydrogen is about 14 times lighter than air and very volatile. This leads to rapid mixing to harmless concentrations with the ambient air.
It has been used in the chemical industry in particular for over 100 years with very good safety ratings.
Hydrogen is no more dangerous than conventional energy carriers such as natural gas, gasoline or petroleum.

Short history of electrolysis
In electrolysis, water is split using electrical energy. The resulting hydrogen is then available for various applications. Hydrogen is always present as a molecule (H2). In addition to hydrogen, oxygen (O2) and waste heat are produced, which can also be used profitably.
Due to the expansion of renewable energies, electrolysers for the production of green hydrogen are becoming increasingly important. In the context of high energy prices, industry has been showing interest in hydrogen technology for years, and the current energy crisis underscores the importance of these technologies.
Hydrogen technologies have been known in industrial circles for decades and the chemical industry in particular has been working extensively with the molecule for over 100 years. Until now, however, the various technologies have had a shadowy existence in the public eye and their potentials were hardly known in any depth to the general public. At the latest since the adoption of the National Hydrogen Strategy of the Federal Government 2020, the hydrogen economy has also moved back into the focus of politics.
Especially since the beginning of the energy crisis, the industry has experienced a radical change accompanied by a growing demand for the technologies and for the potentials that the technology specifically holds for each customer. Hähn is at the forefront. Be one too.
Hähn hydrogen electrolysers
hähn hydrogen electrolysers enable the decentralized and demand-adapted production of hydrogen - even on a small scale.
The plants of hähn hydrogen work with the PEM technology and are available as compact and container plants. If required, we also supply the corresponding periphery.
PEM electrolysers are currently the primary technology used. It is a membrane-based process for splitting water into oxygen and hydrogen using a solid electrolyte. PEM stands for proton exchange membrane or polymer electrolyte membrane.
At the catalytically coated membrane, both the splitting of water into oxygen, free electrons and protons takes place under electrical voltage, as well as the combination to H2. The membranes are only permeable to protons. Together with the anode and cathode, the construct is an electrolytic cell. These are installed in the electrolysis stacks of hähn hydrogen (see picture).
Hähn has been working on hydrogen technologies since its foundation. The expertise of hähn hydrogen has grown over the years and the company is happy to be at your side with their detailed knowledge and solutions.
Currently, a new location with a state-of-the-art production line for stack production and manufacturing of hydrogen systems is being built not far from the current site.
