Claim: Expensive Vanadium Flow Batteries will Make Renewable Energy Viable

Vanadium is expensive, though the price fluctuates wildly – currently $11K to $15K / tonne of Vanadium Pentoxide. But advocates claim Vanadium flow batteries have the potential to solve the…

Battery Basics for Climate Warriors

There are basically only three non-kinetic electrical storage mechanisms: electrochemical, pseudocapacitive, and capacitive. We deliberately exclude indirectly kinetic pumped hydro, for which there are two big expansion problems: insufficient remaining…
