Hydrogen technologies

Hydrogen plays a central role in achieving the climate targets. We are investigating how the individual technologies can be integrated into the energy system and used on a large scale.

Holger Hanselka

Hydrogen technologies are indispensable for the success of the energy transition. They can close the gap between fluctuating electricity generation from renewable energies and the demand for green electricity, replace fossil fuels in industrial processes and link the energy sectors electricity, heat, industry and transport more closely – and do so as efficiently and cost-effectively as possible.

With its unique research infrastructure, Helmholtz is helping to develop, test and market hydrogen technologies. The spectrum ranges from the basics to application and covers the entire value chain.

Hydrogen is only useful to the energy system if it can be stored safely and transported reliably. In the future, the need for storage facilities for large quantities of hydrogen will increase sharply. Various options are possible – from underground storage facilities and the existing natural gas network to new technologies.

Helmholtz scientists are investigating the advantages and disadvantages of underground and natural gas storage facilities for the safe storage of hydrogen. The natural gas network is also suitable for transporting gaseous hydrogen. However, hydrogen can also be stored in solids. When heated, these so-called hydride storage facilities release the hydrogen again.

Another possibility is that hydrogen can react with unsaturated organic compounds to form a liquid organic hydrogen carrier (LOHC), which is stored or transported in a similar way to crude oil. It can be transported safely in tank trucks and trains.

Helmholtz researchers are developing such hydride storage and LOHC technologies and more.
