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.
Elestor’s Hydrogen-Iron Flow Batteries: Powering Europe’s Resilient and Sovereign Energy Future
In its Innovation News Network article from 15 July 2025, Elestor illustrates how its hydrogen‑iron flow batteries can deliver long‑duration, modular energy storage to bolster Europe’s grid stability and strategic autonomy. The story highlights the team’s use of abundant, safe materials and regulatory-aligned design to ensure rapid deployment at scale.
