“How can we store energy using steam?”

 

With the advent of the new energy paradigm, energy storage will play a bigger and bigger factor. Although batteries are promising, they are not an all-encompassing technology and will need support from other systems.

 

One simple method for storing energy involves steam. What if we were to have a container half filled with cold water and connected to a boiler. Steam can be blown if from the boiler into the container, which condenses and warms the water. When the water is about ¾ of the height, it will be considered stable. A valve can then be opened to release energy by driving the steam through a turbine and boiling the water from the resulting pressure drop. This system is known as a Steam Accumulator and is being constructed in conjunction with many solar thermal plants.
