Thermal Energy Storage and Nuclear Power

Compared to fossil fuel energy conversion, nuclear power plants struggle to address the constantly changing electrical loads, a process known as load-following. To meet the fluctuating grid demand, conventional fossil-fuel-based power plants can increase and decrease their power output by burning more or less fuel.
