6 FAQs about [Nuclear power unit pumping gas storage]

What is pumped Energy Storage?

The PSPS is the best tool for energy storage. The pumped storage has the function of energy reserve, and it solves the problem of electricity production and consumption at the same time, and not easy to store. Thus, it can effectively regulate the dynamic balance of the power systems in electricity generation and utilization.

Can a pumped storage facility be regulated?

The current U.S. fleet of operating (single- speed) pumped storage plants does not provide regulation in the pump mode because the pumping power is “fixed” – a project must pump in “blocks” of power - though a single pumped storage facility may consist of multiple units and smaller blocks of power.

Could a low cost heat storage system create a nuclear power plant?

The potential for very low cost heat storage coupled with the low cost of converting electricity to heat also implies incentives to dump low-price electricity into the same heat storage systems creating nuclear power plants that buy and sell electricity.

Why is pumped storage a good tool for load regulation?

As to the pumped storage unit, it is the optimal tool for load regulation with the function of energy storage, as described above. In addition, it is the only kind of unit that can act as the load when the energy demand of the power network is low. Furthermore, in China, there are a large quantity of good PSPS sites to be exploited.

Should Chinese power systems develop pumped storage systems?

The result shows the urgency of developing the PSPS in Chinese power systems that have given priority to thermal power, and the energy resources need the wide-range optimal allocation within the system. The development cycle of the pumped storage is long, and at least 8–10 years are needed from the planning to the completion.

Can a 100 GW heat storage system match a 1000 MW nuclear plant?

To match the yearly energy output of a 1000-MW (electric) nuclear plant with a 100-GW.h heat storage system, the total CSP land area would be near 130 km 2 (50 square miles) for the total output. There is considerable experience in pumping hot oil over distances of kilometers.
