Hydrogen - a vital component on the path to energy transition

Energy obtained from hydrogen is highly versatile, available in almost unlimited quantities and, above all, it is clean. 
For reasons of climate protection, there is, therefore, much to be said for expanding the use of H2. This applies, in particular, to the industrial sector, long-distance transport and the storage of electrical energy. 


As an energy source, hydrogen boasts significant advantages making it a key element of the energy transition, the movement towards the decarbonisation of our energy system. Hydrogen is the most abundant natural element on earth and its availability is, theoretically, almost unlimited. 

The European Union countries have set themselves the goal of reducing their CO2 emissions to zero by 2050. This requires the decarbonisation of various spheres of life and the economy with simultaneous electrification. To this aim, renewable energy sources must be increased and electricity needs to be used as efficiently as possible.

In the process of phasing-out fossil fuels, hydrogen is a promising energy source with almost inexhaustible applications. Not all of these are, however, worthwhile or economically justifiable. Hydrogen contributes to climate protection when it is used in a strategically intelligent way and, above all, when it is obtained using renewable energy sources. 

Electricity should be used directly wherever possible. Only in areas where this is difficult or impossible, does it make sense to use H2. Hydrogen Austria provides support for all those involved in defining these fields of application and developing solutions.

Hydrogen must become greener

Hydrogen occurs on earth only in compound form. For this reason, its extraction involves a number of energy-intensive processes.

Today, most hydrogen is produced using fossil energy sources, which results in the emission of CO2 - the main driver of climate change.  

The splitting of water, i.e. H2O, by electrolysis produces so-called "green hydrogen” and oxygen. When splitting is carried out using energy from renewable sources, the process is emission-free.  

Other emission-free procedures for obtaining hydrogen do exist; these, however, are either (currently) very expensive or they are still in the research and development phase.
