How much does a zinc-iron flow battery cost?
Taking the zinc-iron flow battery as an example, a capital cost of $95 per kWh can be achieved based on a 0.1 MW/0.8 MWh system that works at the current density of 100 mA cm -2 .
Do all zinc-based flow batteries have high energy density?
Indeed, not all zinc-based flow batteries have high energy density because of the limited solubility of redox couples in catholyte. In addition to the energy density, the low cost of zinc-based flow batteries and electrolyte cost in particular provides them a very competitive capital cost.
What is the capital cost of flow battery?
The capital cost of flow battery includes the cost components of cell stacks (electrodes, membranes, gaskets and bolts), electrolytes (active materials, salts, solvents, bromine sequestration agents), balance of plant (BOP) (tanks, pumps, heat exchangers, condensers and rebalance cells) and power conversion system (PCS).
What are the chemistries for zinc-based flow batteries?
2. Material chemistries for Zinc-Based Flow Batteries Since the 1970s, various types of zinc-based flow batteries based on different positive redox couples, e.g., Br - /Br 2, Fe (CN) 64- /Fe (CN) 63- and Ni (OH) 2 /NiOOH , have been proposed and developed, with different characteristics, challenges, maturity and prospects.
What are the advantages of zinc-based flow batteries?
Benefiting from the uniform zinc plating and materials optimization, the areal capacity of zinc-based flow batteries has been remarkably improved, e.g., 435 mAh cm -2 for a single alkaline zinc-iron flow battery, 240 mAh cm -2 for an alkaline zinc-iron flow battery cell stack , 240 mAh cm -2 for a single zinc-iodine flow battery .
Are alkaline zinc-iron flow batteries safe?
Alkaline zinc-iron flow batteries attract great interest for remarkable energy density, high safety, environmentally benign. However, comprehensive cost evaluation and sensitivity analysis of this technology are still absent.
