Long-Duration Energy Storage: Why the Grid's Hardest Problem Isn't a Battery Problem
Lithium-ion shifts power by hours. The grid's real challenge is shifting it by days. That gap is where long-duration storage lives — and where the sustainability case has to be measured, not assumed.

Battery Recycling in 2026: When Sustainability Becomes Supply-Chain Security
The recycling you learned as a child is not the industry reshaping battery supply chains today. Recovering critical minerals from spent cells is now strategy as much as sustainability — where the claims hold up.

Second-Life EV Battery Economics: Stationary Storage's Most Contested Supply
Used EV packs are flowing into stationary applications, but warranty, integration, and SOH variability create real constraints. We map the supply economics for the next 24 months.
