Bankable batteries: markets, execution, and trust

On this episode of the Hypercube Energy Podcast, Adam Sroka speaks with Antonio Montoto, Head of Storage at Greenvolt Power, about how battery storage has evolved from niche, bespoke projects into core infrastructure for modern power systems and what it really takes to deliver storage at scale across global markets.

Antonio shares his journey from working on early, technically driven storage projects to leading utility-scale battery portfolios across Europe, the US, and Japan. He explains how the challenges facing storage have shifted over the past decade, from understanding degradation and cycling limits to executing complex projects, securing bankability, and integrating batteries into increasingly competitive energy markets. The conversation explores how market maturity, regulation, and geography shape storage outcomes, and why realistic returns, strong execution, and the right mix of software and in-house expertise are critical to long-term value.

Adam and Antonio cover:

• Antonio’s role at Greenvolt Power and how large-scale storage portfolios are built
• Why battery storage has moved from bespoke use cases to mainstream grid infrastructure
• Where storage projects most commonly fail and how experienced teams avoid it
• The gap between engineering reality and financial bankability
• How regulation and market maturity differ across regions
• What’s really changed in battery hardware over the past decade
