Using reservoirs for energy storage

Should energy storage be used in depleted oil and gas reservoirs?

You have full access to this open access article Utilizing energy storage in depleted oil and gas reservoirs can improve productivity while reducing power costs and is one of the best ways to achieve synergistic development of "Carbon Peak–Carbon Neutral" and "Underground Resource Utilization".

What are the advantages of using depleted reservoirs for energy storage?

The advantages of using depleted reservoirs for energy storage are the availability of detailed geological information and historical production records, lower exploration costs and shorter construction periods.

Why do hydropower stations use reservoir storage?

In operations, hydropower stations utilize their own reservoir storage to redistribute uneven inflows over periods of years, months, weeks, days or hours, thereby controlling when and how much electricity is generated. This ability enables them to quickly respond to the increasing demand for flexible power in electrical grids 2, 3.

What is the importance of depleted oil & gas reservoirs?

The development of depleted oil and gas type reservoirs is of great significance to the change of energy structure and the promotion of the development of energy technology, and also lays a solid foundation for the construction and development of smart grids, energy internet and smart cities (Feng 2023).

What is geological thermal energy storage (GeoTES)?

Geological Thermal Energy Storage (GeoTES) Charged with Solar Thermal Technology Using Depleted Oil/Gas Reservoirs and Carnot-Battery Technique Using Shallow Reservoirs: Preprint. Golden, CO: National Renewable Energy Laboratory. NREL/CP-5700-88744.

What is pumped storage hydropower?

Pumped storage hydropower is a type of hydroelectric power generation that plays a significant role in both energy storage and generation. At its core, you've got two reservoirs, one up high, one down low. When electricity demand is low, excess energy from the grid is used to pump water from the lower to the upper reservoir.
