Lithium-ion batteries were developed in 1970 by a British scientist named Stanley Whittingham. However, they were not used commercially until 1991. They are the most common form of energy storage technology that we have today. With the growth of technology, lithium-ion batteries are far more advanced than in the 70s or even the 90s.
Many of these technologies can be deployed at multiple scales, but batteries represent the most scalable energy-storage technology. For example, a Tesla power wall in a home has the capacity to store 13.5 kWh of energy, while a Tesla mega pack array can store 1,000,000 kWh of energy for utility-scale applications.
Furthermore, energy storage provides increased reliability and strengthens system resilience at large and small substation levels. Energy storage is commonly used in transportation devices, like electric vehicles, trains, and bikes.
