> The molecule is also highly soluble, meaning it can store more energy in a smaller space. It operates in a weak alkaline electrolyte, reducing the cost of the battery by allowing the use of inexpensive containment materials and an inexpensive polymer membrane to separate the positive and negative terminals.

How much power does it output - it's a new electrolyte for a flow battery, so this means for large systems measured in kW and hundreds of kWh storage.
