Gas pressure energy storage power station

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.

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.

What is a battery storage power station?

A battery storage power station is a device designed to output power at its full rated capacity for several hours. It can be used for short-term peak power and ancillary services, such as providing operating reserve and frequency control to minimize the chance of power outages.

What is a pumped storage power station?

The pumped storage power station consists of two circular concrete silos, each of about 32 metres (105 ft) internal diameter. Each of the silos houses a 250 megawatts (340,000 hp) turbine generator and pump set, giving a total capacity of 500 megawatts (670,000 hp).

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.

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.
