Naturally, the financial aspect will always be a compelling factor. However, the key to unlocking the potential of flow batteries lies in understanding their unique cost structure and capitalizing on their distinctive strengths. It’s clear that the cost per kWh of flow batteries may seem high at first glance.
It’s integral to understanding the long-term value of a solution, including flow batteries. Diving into the specifics, the cost per kWh is calculated by taking the total costs of the battery system (equipment, installation, operation, and maintenance) and dividing it by the total amount of electrical energy it can deliver over its lifetime.
Flow batteries also boast impressive longevity. In ideal conditions, they can withstand many years of use with minimal degradation, allowing for up to 20,000 cycles. This fact is especially significant, as it can directly affect the total cost of energy storage, bringing down the cost per kWh over the battery’s lifespan.
However, the key to unlocking the potential of flow batteries lies in understanding their unique cost structure and capitalizing on their distinctive strengths. It’s clear that the cost per kWh of flow batteries may seem high at first glance. Yet, their long lifespan and scalability make them a cost-effective choice in the long run.
The research and analysis conducted for this report were supported by the European Climate Foundation. This report is part of a series that analyses the battery storage market in select European countries. Italy has both a rapidly growing utility-scale market as well as a flourishing customer-sited battery storage market.
At their heart, flow batteries are electrochemical systems that store power in liquid solutions contained within external tanks. This design differs significantly from solid-state batteries, such as lithium-ion variants, where energy is enclosed within the battery unit itself.
