It is increasingly interesting to use energy storage to obtain solar energy for later use at home to reduce reliance on traditional utilities.
However, few studies have conducted a critical assessment of trade
The shutdown associated with storing solar energy, rather than sending solar energy to the grid as it is usually done today.
Here we show that a typical battery system can reduce peak power demand by 8-32% and peak power injection by 5-42% depending on how it operates.
However, storage is inefficient and the average annual energy consumption per household has increased by 324-591 kWh.
In addition, the storage operation indirectly increased the emissions of 153-303 kg/kg CO2, 0. 03–0. 20 kg/kg SO2 and 0. 04–0.
Every household in Texas has 26 kilograms of NOx per year.
Therefore, it will not automatically reduce emissions or energy consumption unless household energy storage makes direct use of renewable energy.
