I’m sure your first question is: what the heck is nanoelectrofuel (NEF). Since that is the main subject of this paper, we will get to that herein, but first let’s talk about the current state of the art for flow batteries. In case you don’t really know much about these, I’m partially to blame, because I haven’t written about the for a couple of years. The last post was in 2020 and is summarized and linked in the introduction to this paper.
However, below are the basic metrics for the Vanadium Redox flow battery.
- Charge/discharge roundtrip efficiency: 65% to 75%
- Typical charge/discharge cycle life: 10,000 cycles
- Present value of installed cost: $5,800 to $6,600 per kW
- Levelized cost of energy: $260 to $300 per MWh
Although, given the right application, these have a place, their niche is very narrow…
