Energy - Process for energy storage and transport

The expanding installation of wind and solar plants leads inevitably to peaks in electricity generation. As a result, surplus electricity is generated in windy and sunny periods, which to an increasing share cannot be fed into the grid. On the other hand, the deconstruction of conventional power plants causes supply gaps in times of low wind and sun. Therefore, the development and installation of innovative long term storage technologies is one of the main challenges in the transformation of the energy system. In order to tackle this challenge, this solution has developed its own system of power-to-gas technology. With this process, electricity can be converted into hydrogen by electrolysis. This hydrogen can either be used directly or, in a second step, converted together with carbon dioxide from a biogas or sewage plant into methane gas.
