High-pressure water and gas energy storage pump station

What is energy storage system based on water pumping?

In the last part of the research, an energy storage system was designed to store the generated electrical energy. For this purpose, an energy storage system based on water pumping in water towers was designed. Water towers with different classes were investigated.

What is the best energy storage method based on water pumping?

3.2.1. Energy analysis of energy storage system based on water towers Energy storage in a water tower is a special method of pumped-hydro energy storage system. This energy storage mechanism proposed in this research is the best energy storage method based on water pumping for a gas pressure reduction station.

What is pumped storage hydropower (PSH)?

Pumped storage hydropower (PSH) currently accounts for over 90% of storage capacity and stored energy in grid scale applications globally. The current storage volume of PSH stations is at least 9,000 GWh, whereas batteries amount to just 7-8 GWh.

How does a gas pressure reduction station store energy?

In order to store the electrical energy generated as a result of energy recovery in the gas pressure reduction station, the pumps transfer water from the water reservoir to the tank above the water tower by consuming that energy and thus store the energy in it.

Does gas pressure reduction station have energy recovery system?

Currently, the gas pressure reduction station does not have an energy recovery system; hence, energy of high-pressure natural gas is wasted in it. For this reason, first, the energy recovery system was thermodynamically designed based on the use of a turbo-expander instead of the regulator, and the extracted energy was calculated.

How does energy storage work?

As shown in Fig. 1, in this method, in the energy storage stage, the pump transfers water from the water reservoir to the water tower tank using the energy generated by the turbo-generator installed in the gas pressure reduction station.
