The energy transition it is not just a question of political will, economic or commercial rules and factors. To make the transformation of our energy production model concrete, it is not enough to pass a law. The question is much more complex and also (or above all) passes through the resolution of technological problems. One of the most important is that of energy storage. When it comes to the energy transition, the first thought that probably comes to mind is how to replace traditional sources with more “green” and renewable ones. It is much less immediate to think about how to conserve the energy that we are already able to produce with these alternative sources and that we will have to produce more and more in the future.
And yet it is such an important problem that, a few days ago, the heads of numerous companies in the energy sector and scientists from prestigious European research institutes wrote an open letter to the media and EU policy makers. The letter (signed by the director of the Karlsruhe Institute of Technology and the head of the Department for Electrical Storage of the Fraunhofer Institute of Solar Energy Systems) is inspired by the REPowerEU Planthe energy plan promoted in May by the EU and notes how “the current geopolitical situation in the continent, combined with the high dependence on natural gas imports, the growing demand for electricity and, consequently, the increase in household bills and businesses, he determines an urgent need to rethink the structure of European energy systems. […] For this plan to be successful, it must be accompanied by objectives and political programs adequate for the diffusion of technologies for the storage of energy and other technologies that allow for flexibility ”.
The authors refer to that set of technologies necessary to make “the safe and efficient integration of renewables into the European energy grid and the time has come to recognize them as the pillars of the European energy transition”. Among these technologies, “battery-based energy storage is a quickly available, cost-effective and low-emission solution, with the potential to become a backbone of modern, resilient and decarbonised energy systems. “. In other words, what the signatories are asking is the adoption of modern technological solutionsadequate and coherent, to face the increasing demands for balancing energy demand and supply.
