1. PUMPED STORAGE HYDROELECTRICITY

Pumped storage hydroelectricity represents a pivotal avenue for energy storage, harnessing gravitational potential to create a reservoir of energy. This technique operates by elevating water to a higher altitude during periods of low electricity demand. When energy is required, the stored water is released, flowing back down to generate electricity. This dual functionality allows for rapid energy release, making it particularly beneficial during peak consumption times, thus promoting grid stability.

The development and expansion of pumped storage facilities by CGN exemplify their commitment to enhancing energy security. By establishing reservoirs in strategic locations, CGN can not only optimize energy distribution but also respond promptly to fluctuations in electricity demand. The scale and efficiency of these operations are significant, often capable of generating thousands of megawatts of power within minutes. Essentially, this technology serves as a large-scale battery, supporting the reliability of renewable energy sources by mitigating intermittent supply issues.

Hydrogen, often regarded as the fuel of the future, holds the potential to serve as a formidable energy storage solution. CGN has explored various methods of producing hydrogen through electrolysis, particularly during periods of low demand when surplus electricity is available. This process allows for the conversion of excess electrical energy into chemical energy, stored in the form of hydrogen gas.

The long-term storage capabilities of hydrogen provide a unique advantage over traditional battery systems. As a clean energy source, hydrogen can be utilized across multiple sectors, including transportation and industry, ultimately contributing to a decarbonized economy. CGN’s commitment to exploring hydrogen production and storage underscores their dedication to diversifying their energy portfolio while enhancing resilience. This diversification is essential in adapting to changing market demands and aligns with global energy transition efforts.

FREQUENTLY ASKED QUESTIONS

WHAT IS PUMPED STORAGE HYDROELECTRICITY?

Pumped storage hydroelectricity is a technology designed for energy storage and regulation within power grids. It operates by pumping water to an elevated reservoir during low electricity demand periods, storing gravitational potential energy. When demand increases, the water is released back through turbines, generating electricity. This system supports grid stability, particularly during fluctuating renewable energy production, and allows for efficient electricity management. Pumped storage can respond rapidly to energy demand fluctuations, making it essential for integrating intermittent renewable energy sources like solar and wind, which can experience variations in production.

HOW DO BATTERY STORAGE SYSTEMS WORK?

Battery storage systems function by storing electrical energy in chemical form and releasing it when necessary. These systems typically use various technologies, including lithium-ion and flow batteries, to facilitate energy retention. During low-demand periods, excess electricity can be stored within batteries, which can then be discharged when needed, supporting energy supply during peak hours. The efficiency and scalability of battery systems have made them paramount for harnessing renewable energy, allowing companies to reduce reliance on fossil fuels and achieve greater energy independence. Furthermore, advancements in battery technology continue to enhance their abilities to hold charge longer, reduce costs, and improve life cycles.

WHAT ROLE DOES THERMAL ENERGY STORAGE PLAY IN ENERGY MANAGEMENT?

Thermal energy storage (TES) systems play a critical role in managing energy by capturing and storing heat energy generated during off-peak times. In essence, this allows producers, like CGN, to utilize surplus thermal energy when demand is high, effectively reducing peak electricity usage. TES can be implemented alongside renewable energy sources, such as solar thermal plants, where excess heat can be stored for later application. By smoothing out the variation in energy supply and demand, thermal energy storage enhances the reliability of energy systems, helps to align energy generation with consumption patterns, and ultimately contributes to overall efficiency in energy management practices.

In summation, the multifaceted approach taken by China General Nuclear Power Corporation in energy storage not only enhances the operational efficiency of their energy generation systems but also promotes sustainability across the energy sector.
