Hydrogen is perhaps the gas with the greatest significance for the energy transition. This is because it has important properties that are needed for the transition to a climate-neutral energy supply. Hydrogen can store energy over long periods of time and can also be transported over long distances using the existing gas grid. With properties similar to those of natural gas, it can replace fossil fuels where electrification is hardly possible - for example, in the generation of process heat.

Hydrogen can be produced by various processes. Depending on how it is produced, hydrogen is divided into different color categories: for example, turquoise hydrogen is a product from so-called methane pyrolysis, blue hydrogen comes from steam reforming and CCS. Green hydrogen a product from electrolysis powered by renewable energy. Orange hydrogen comes from the recycling of waste and wastewater, e.g. by means of plasmolysis technology.

Green hydrogen is particularly sought after because it is indispensable for certain production processes as a low-CO2 alternative, and its production is considered the most climate-friendly option. Additional energy capacity could be sourced both through imports and by adding turquoise or blue hydrogen. This could reduce cost pressure and provide additional energy security.
