Energy retention plays a key function in integrating renewable energy sources (RES) into electricity systems, enabling network stableness and efficient management of production and energy consumption. China, as a global leader in RES, is intensively developing energy retention technologies to meet the challenges of instability of sources specified as solar or wind energy.
Development of energy retention technologies in China
Initially, China focused on conventional retention methods specified as peak-pumped power plants. However, with the dynamic increase in RES participation, the country has invested in modern technologies, including:
- Lithium-ion batteries: Widely utilized in both individual and industrial applications, thanks to advanced energy density and long service life.
- Sodium ion batteries: In 2023, China launched its first test energy warehouse based on sodium-ion cells with a capacity of 10 MWh, with expansion plans of up to 100 MWh.
- Energy retention based on flywheel technology: In 2023, China launched the world's largest energy warehouse based on this technology, which demonstrates their advancement in innovative solutions.
- Compressed air energy retention (CAES): Jintan Salt Cavern CAES, an energy warehouse utilizing compressed air in salt caves, is formed in Changzhou province.
Distribution of energy storage
- Storage for individual use: household systems, frequently integrated with photovoltaic installations, let for increased auto-consumering and energy independence.
- Warehouses for industrial use: Large energy retention systems utilized in manufacture and at the level of energy networks to stabilise networks, manage burden and integrate RES.
Leaders in the production and investigation of energy retention in China
- CATL (Contemporary Amperex Technology Co. Limited): 1 of the world's largest producers of lithium-ion batteries, supplying both the home and global markets.
- BYD (Build Your Dreams): A company known for producing electrical vehicles and energy retention systems, active in many global markets.
- HiNa Battery Technology: A supplier of sodium-ion batteries, utilized in the world's first 100MWh Na-ion energy warehouse.
Importance of energy retention in RES-based systems
Energy retention is crucial for the stableness and efficiency of renewable energy systems. Allow:
- Buffering energy surpluses: retention of surplus energy produced in high-generation periods (e.g. on sunny days) and its usage in periods of scarcity.
- Network stabilisation: Ensuring a balance between production and energy consumption, which is crucial for unstable RES sources.
- Load management: Optimising energy consumption by storing it in periods of low request and releasing it at highest moments.
The deficiency of adequate energy retention systems constitutes an crucial barrier to the improvement of “green energy”. Without warehouses, it is hard to effectively integrate unstable RES sources into the network, which can lead to congestion, energy shortages and simplification of renewables potential. The underestimation of the function of energy warehouses shows a deficiency of full knowing of the specifics and requirements of modern energy based on RES.
Eenovance company and its expansion into the Polish market
Eenovance is simply a Chinese company specializing in energy retention solutions for various segments of the market. It offers products specified as inverters, batteries and comprehensive energy retention systems, adapted for both individual and industrial use. The company plans to enter the Polish market, which can contribute to the further improvement and implementation of modern energy retention technologies in Poland.
China plays a key function in the global improvement of energy retention technologies, investing in a variety of solutions for both individual and industrial users. The presence of companies specified as Eenovance in the Polish marketplace can contribute to the further improvement and implementation of modern energy retention technologies in Poland, thereby supporting energy transformation and expanding the share of renewable energy sources in the national energy mix. Thanks to Chinese innovation and dynamic improvement of energy retention technology, Poland has a chance to increase the efficiency of systems based on renewable sources, which at the same time will contribute to achieving climate neutrality objectives.
The improvement of energy retention is simply a key component of the energy transition, allowing the full possible of renewable energy sources to be overcome. China, as a planet leader in this field, sets out the direction that another countries follow, and their experience and technology can become a model for Poland as well. It is worth tracking the improvement of companies like Eenovance, which not only bring modern technological solutions, but besides support global energy transformation through their global activities.
