Batteries Events 2022, held last week in Lyon, France, hosted a special session on zinc batteries. Other special sessions were dedicated to sodium-ion batteries and lead-acid batteries. Having all these sessions at one of the largest battery events in Europe tells me that all battery types and chemistries have a role to play in the energy transition. While lithium-ion batteries and lead-acid batteries already have strong positions in the automotive and energy storage markets, new technologies as zinc and sodium-ion batteries can serve complementary roles.

The forecasts for deployed stationary energy storage capacity with batteries is about 1.2 TWh by 2030, and a stunning 7.7 TWh by 2050, according to a recent report by Bloomberg NEF. Approximately 90 percent of this global market requires energy batteries, while only 10 percent requires power batteries. While lithium-ion typically function best as power batteries, zinc batteries, lead-acid batteries and sodium-ion batteries mostly shine as energy batteries.
