Energy storage is a valuable tool for balancing the grid and integrating more renewable energy. When energy demand is low and production of renewables is high, the excess energy can be stored for later use. When demand for energy or power is high and supply is low, the stored energy can be discharged. Due to the hourly, seasonal, and locational
The MITEI report shows that energy storage makes deep decarbonization of reliable electric power systems affordable. "Fossil fuel power plant operators have traditionally responded to demand for electricity — in any given moment — by adjusting the supply of electricity flowing into the grid," says MITEI Director Robert Armstrong, the
The current environmental problems are becoming more and more serious. In dense urban areas and areas with large populations, exhaust fumes from vehicles have become a major source of air pollution [1].According to a case study in Serbia, as the number of vehicles increased the emission of pollutants in the air increased accordingly,
