This Week in Cleantech is a weekly podcast covering the most impactful stories in clean energy and climate featuring Paul Gerke of Factor This and Tigercomm’s Mike Casey.

This week's episode features special guest Robison Meyer from Heatmap News, who discussed how local opposition to data centers hit a new record in the first quarter of 2026.

This week’s “Cleantecher of the Week” is Tom Sisto, CEO of XL Batteries. XL Batteries makes an organic flow battery that lasts for 250 hours. The technology runs on non-toxic, non-flammable electrolytes, meaning these batteries can be deployed in population-dense communities without the heavy permitting scrutiny that is required for similar-sized lithium-ion installations. Congratulations, Tom!
