re is a wide range of storage solutions to choose from – energy storage systems enable you to use electricity when you need it

The energy system is in the midst of a transition – and the process is happening faster than most people realise. The share of renewable energy of the total electricity produced in Germany already amounts to around one third of the energy mix. This means that wind and solar power are now the most important energy sources after coal. The Federal Government plans to continue to expand this share: by 2035, 55 to 60 per cent of all electricity is to be generated from renewable sources.

In order for these plans to become reality, however, more is needed than just the expansion of power plants for renewable energy. Because the availability of solar and wind power varies according to the weather, storage technology is becoming more and more important. Efficient storage solutions are essential because these enable us to use the electricity from renewable sources even if there are shortages in the electricity supply caused by factors such as a lack of wind or sun.

innogy is one of the leading companies researching this field and is involved in the development of numerous technologies. Below, we introduce some of the most promising storage solutions, some of which you could even use in your own home.
