21 June 2016 storage of produced energy as methan gases from ecological waste and wind energy http://www.wiwo.de/technologie/green/tech/energiespeicherung-methan-aus-bioabfall-und-windstrom/13766452.html
As to an oral information to me it is necessary for companies to have access to more current energy, because they need that much current. Which companies are those? Instead we produce in Germany too much current and deliver the overproduction abroad. We even pay the receivers, that these please might be so kind and take our overproduction. But storage is possible, already now. Is this is the end of a political system of “leaders” who are not interested in the needs of citizens? Here in Wirtschaftswoche we can read that scientists want to produce Biomethan from superfluous current energy, to be implemented into the earth gaz-grid.
Instead famous University in Zurich / Switzerland made an invention, how gases at the production of oil in the gulf or other regions can be used, instead of burning, i.e. to make the whole process more efficient. If we need oil for chemistry and pharmacy – than in an efficient way of being produced.
