Where are the flow batteries? (fuel cells) Lithium ion batteries are light with a high energy density, so are great for cars. Flow batteries have a low energy density, but increasing the duration means a bigger tank, and the cost of bigger tanks increases as a function of the cube root (?) of their volume
Flow batteries are well over a century old, but I have been reading about improvements over the last two decades. Where are they? |
