High energy prices affect both social justice and the competitiveness of the economy in Germany. Because energy has become increasingly expensive since the start of the energy turnaround, large sections of the population fear that their cost of living will become unaffordable. How a cost-reducing and socially acceptable energy turnaround can look like and what role hydrogen plays in it will be explained by Dirk Böllert (ADAICA Germany) in his lecture on Thursday, April 27, at 17:30 as part of the lecture series of the Hydrogen Alliance South Lower Saxony. For this purpose, he will present a special cellular approach with demand-side integration of renewable energy generation in regional, interconnected subsystems. ADAICA Deutschland GmbH has been working for many years on the digitalization of energy grids, especially of municipal utilities.
