Types of Battery Energy Storage Systems (BESS) Explained
One of the oldest types of rechargeable batteries, lead-acid is still widely used in applications like off-grid power systems and backup power supplies (UPS). They are cheaper
Currently, stationary energy-storage only accounts for a tiny fraction of the total sales of lead–acid batteries. Indeed the total installed capacity for stationary applications of lead–acid in 2010 (35 MW) was dwarfed by the installed capacity of sodium–sulfur batteries (315 MW), see Figure 13.13.
It consists of lead dioxide and sponge lead electrodes submerged in a dilute sulfuric acid electrolyte. According to the Department of Energy, lead acid batteries are widely used in applications where high power is needed, such as in vehicles and backup power systems.
Lithium-ion battery cabinets are popular for their high energy density, long cycle life, and efficiency, making them suitable for both residential and commercial applications. Lead-acid battery cabinets are well-known for their cost-effectiveness and reliability, though they offer lower energy density compared to lithium-ion batteries.
One of the oldest types of rechargeable batteries, lead-acid is still widely used in applications like off-grid power systems and backup power supplies (UPS). They are cheaper than lithium-ion but have a shorter lifespan and lower energy density. Pros: Low cost, widely available, recyclable.
