Coupling water storage with solar can successfully and cost effectively reduce the intermittency of solar energy for different applications. However the elaborate exploration of water storage mediums (including in the forms of steam or ice) specifically regarding solar storage has been overlooked.
For example, when we have lights on, it’s all coming from a power plant that is using a carbon source to generate electricity. The two most popular ways to store energy are batteries and fuels. What people don’t realize is batteries have a limited storage capacity. The best batteries store energy 50 to 100 times less than fuel.
Among the most reliable and cost effective storage mediums, water has been always a favorable option due to its high specific heat, non-toxicity, lower costs, chemical stability, availability and high capacity rate during charge and discharge (Alva et al., 2017, Xu et al., 2014).
When there are two storage reservoirs (upper and lower), some of them may be a river or even the sea separated by a height, h. This determines the gross energy stored. The units in the international system are Joules (J), but normally in electricity, kilowatts per hour (kWh) is used.
To store energy, the system uses electricity to pump water out into the sea. When discharging, the pump works in reverse, generating electricity as water refills the sphere. In November, Fraunhofer IWES installed a 3-meter-wide pilot sphere in southern Germany’s Lake Konstanz at a depth of around 100 meters.
Applying water/steam medium for solar storage is capable of producing heat up to 380–400 °C, which expands the water storage potential to be used in various high-temperature industrial applications while being environmentally safe.
The present work is an effort to provide an elaborated evaluation on all those storage technologies that use "pure water" as their main medium. This includes both thermal …
