Energy Storage Systems Background and Trends

In almost every region of the world, government regulators have outlined a decarbonization roadmap to reduce climate change impact.  Many countries are targeting the year 2050 for net-zero carbon dioxide (CO2) emissions. 

Today, electricity is primarily generated by fossil fuels which emit CO2.  In order to meet 2050 net-zero targets, an energy generation renewable mix will be required to phase out fossil fuel generation.  Renewable generation includes wind turbine, solar, hydropower, and Energy Storage Systems (ESS). 

ESS, also referred to as grid storage, serves as a central catalyst for modernizing and creating a more reliable and resilient, efficient, sustainable, and affordable grid.  ESS systems typically charge when there is low demand on the electric grid and discharge during peak demand.  This strategy prevents additional fossil fuel generation from coming online, which is also more expensive during peak demand.  The two battery technologies most ESS integrators are deploying include Li-ion and AGM batteries.

What is an AGM Battery?

AGM batteries, or absorbent glass mat batteries, are a technological improvement to traditional flooded lead batteries. AGM batteries have become the advanced lead battery choice backing up the electric grid due to their reliability, scalability, and maintenance-free design. 

The AGM battery has been the lead battery global preference for grid storage.  AGM batteries are a proven technology, reliable, maintenance-free, safe, lower up-front cost compared to Li-Ion, and recyclable.
