Knowledge Space Hydrogen

The most common and lightest element in the universe has in its molecular form of H₂ the most stable and therefore the most energetic of all chemical single bonds. This energy forms the basis of all life and naturally it has always been used. The development of its technical use is currently experiencing an upswing.

Hydrogen is used energetically to provide electricity and heat, or as a fuel. Furthermore, it is used as a starting material in the chemical industry. With the advancing decarbonisation of the economy, the number of possible applications and the quantities required are increasing rapidly.

For the success of the energy transition, hydrogen (H₂) is assigned a central role on a global, national and regional level. In this context, numerous countries have already published their own development strategies for the energy carrier, which provide a political framework for the future production, storage and use of H₂ in order to increase not only its economic viability but also its usability in all sectors. 

Modern electrolysis plants use electricity from renewable energies. These special power-to-gas processes use the surplus electricity from renewable energy plants such as photovoltaics and wind turbines to produce green hydrogen. How much energy is needed to produce hydrogen and which electrolysis processes can be used for this, you can learn here.

The official ARON home energy design tool for private households uses your input to estimate the technical and economic potential of a photovoltaic system, heat pump and the use of a battery home storage system.
