Ideal solution

The Elestor battery makes hydrogen gas-fired power plants obsolete, thus proving to be the ideal solution to reliable and efficient energy storage in the transition to green energy.

As the transition to sustainable energy progresses, reliance on intermittent, unpredictable sources like sun and wind continuously increases while the predictable generation of fossil-based electricity is faded out. Though occurring statistically only once or twice per year, these changes in the electricity generation lead to dark and windless periods – in German referred to as the ‘Dunkelflaute’ – sometimes lasting several days. The question to be answered is how such periods can be managed to ensure the availability of sufficient electrical energy at any time and at the lowest possible costs.
