In this episode Sean learns all about quinone flow batteries, ferrocyanide, and a lot more, including how desalination and air conditioning are related and can use the same membrane redox-flow technology.

 

It was a pleasure to have a very intelligent guest with degrees from Harvard and Stanford. We will learn what a flow battery is and its benefits and how they expect to be a greater part of the renewable mix in the future.

 

The water-based technology is different from the acid-based vanadium redox flow batteries, which require vanadium, and much of the vanadium comes from Russia, while quinone can easily be made anywhere, lessening dependence on faraway places, which fits with where our economy seems to be headed.

 

Here are some of the topics we cover:

 

What is a flow battery?

Thermal runaway

What is LDES? Your definition and benefits

Different types of LDES

Flow batteries benefits

Benefits vs Vanadium or Zinc Bromine or others

Full to no charge how many times

How long does the electrolyte and membrane last?

Toxicity

Power block cost

DOE 250/kW

40/kWh

What did you do with that $100

Can you theoretically use electrolyte for an EV?

How did you get DOE funding?

What is quinone

Pioneered at Harvard

Energy density and specific energy?

R/T efficiency

Ferrocyanide and quinone

Temperatures
