Gates, Bezos Bet On Flow Battery Technology, A Potential Rival To Big Bets On Lithium-Ion

The title of this post is the same as that of this article on CNBC.

This is the first paragraph.

The U.S. energy storage market is expected to grow by a factor of 12 in the next five years, from 430MW deployed in 2019 to more than 5GW and a value of more than $5 billion by 2024, says Wood Mackenzie Energy Storage Service.

Those are big numbers and it makes me ask the question of whether Planet Earth has enough lithium.

The title of the article says that Bill Gates and Jeff Bezos are looking at flow battery technology, as a possibly alternative to lithium-ion batteries.

What Is Flow Battery Technology?

This is the first sentence of the Wikipedia entry for flow battery.

A flow battery, or redox flow battery (after reduction–oxidation), is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids contained within the system and separated by a membrane.

Wikipedia’s explanation is comprehensive.

  • There are seven different types.
  • There are around twenty different chemistries.
  • They have various advantages and disadvantages.
  • They seem to be less efficient than lithium-ion batteries.

Applications include; load balancing, uninterruptible power supplies, power conversion, electric vehicles and standalone power supplies.

It looks like they are a lithium-ion replacement.

Conclusion

This technology is one to watch.

With all those types and chemistries someone could strike extremely lucky!
