High oil pressure 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 is high-flow pressurized gas storage?

The primary focus of high-flow pressurized gas storage is on pipe column safety and the study of injection and extraction schemes. Currently, international research on utilizing depleted oil and gas reservoirs for gas storage is still in the exploratory and theoretical analysis stage.

What are the advantages of a large-scale energy storage system?

With advantages such as substantial storage capacity, extended storage duration, high system efficiency, long operational lifespan, flexibility, intermittency management, low cost, and scalability, CAES is regarded as one of the most promising large-scale energy storage technologies (Ozarslan 2012; Wan et al. 2023a; Wang et al. 2018).

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).

Why is energy storage important?

Energy storage options like CAES are particularly important in the transition to clean energy, according to the researchers, because they help address the intermittent nature of renewable sources. By storing excess renewable energy and releasing it when needed, energy storage contributes to grid stability and reliability.

Does CO2 migrate in low permeability heavy oil reservoirs?

However, analyzing the migration and storage effects of CO 2 in low permeability heavy oil reservoirs is challenging. In this study, high-pressure and high-temperature (50 MPa,100 °C) microfluidic experiments were designed and carried out, and the CO 2 flooding characteristics and storage efficiency were studied.
