Capital cost of utility-scale battery storage systems in the New Policies Scenario, 2017-2040 - Chart and data by the International Energy Agency.
Where can you get >100 MW equivalent of RFB stacks and stack components Can you build a sustainable billion-dollar business by manufacturing and selling batteries at low margins? Who
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.
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.
The landscape of utility-scale battery storage costs in Europe continues to evolve rapidly, driven by technological advancements and increasing demand for renewable energy integration. As we’ve explored, the current costs range from €250 to €400 per kWh, with a clear downward trajectory expected in the coming years.
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.
The largest component of utility-scale battery storage costs lies in the battery cells themselves, typically accounting for 30-40% of total system costs. In the European market, lithium-ion batteries currently range from €200 to €300 per kilowatt-hour (kWh), with prices continuing to decrease as manufacturing scales up and technology improves.
Let’s look at some key aspects that make flow batteries an attractive energy storage solution: Scalability: As mentioned earlier, increasing the volume of electrolytes can scale up energy capacity. Durability: Due to low wear and tear, flow batteries can sustain multiple cycles over many years without significant efficiency loss.
