A New Approach to Energy Storage | Thomas Nann, Founder & CEO @ Allegro Energy

Energy storage and grid infrastructure sit at the center of nearly every serious conversation about the clean energy transition. Generating renewable power is one challenge. Making sure that power is available when and where it is needed is another challenge entirely, and it may be the harder one.
On The Grove, this topic comes up again and again because the guests working on it are rethinking problems that the energy industry has carried for decades. From novel battery chemistries to smarter grid coordination, the work happening in this space is as much about system design as it is about any single technology. Thomas Nann of Allegro Energy, for example, represents a wave of founders who are not simply improving on existing storage solutions but questioning the assumptions behind them.
The throughline across these episodes is practical urgency. Grids built for centralized fossil fuel generation are being asked to handle distributed, variable renewable sources, and the gap between what exists today and what is needed tomorrow is significant. The researchers, engineers, and founders who appear on this show are working directly in that gap.
If you found this page while researching energy storage technologies, grid modernization, or the business of climate infrastructure, these conversations offer something that white papers and press releases rarely do: honest accounts of what the work actually involves, what is proving harder than expected, and where real progress is being made. Start with any episode and follow the threads that interest you most.
