Summary

In this episode of Transmission, host Ed Porter interviews Marek Kubik, an industry expert based in Saudi Arabia, about the rapid changes in the battery storage sector. They discuss the surprising growth of battery storage in the Middle East, with Saudi Arabia going from zero to 18 GWh operational in just over a year. The conversation covers the dramatic fall in battery system costs since 2022, driven by scale and innovation, but notes recent increases in raw material prices and Chinese anti-involution measures. They explore the potential of sodium-ion batteries to replicate LFP’s takeover, highlighting its lower raw material costs and longer cycle life, though density remains a trade-off. The discussion also examines CATL’s declining market share and the fragmentation of the supplier market, contrasting with the historical fall of Korean manufacturers. They touch on container design innovations, long-duration storage, and the role of flow batteries and other emerging technologies. The episode concludes with insights on the future of sodium-ion and the importance of adapting to a rapidly evolving industry.
