When it comes to grid level energy storage and integrating renewable energy sources such as solar power, lithium ion batteries have emerged as the technology of choice. The reasons behind this preference warrant closer examination.
The selection of a battery for an energy storage system (ESS) hinges on several key characteristics that customers tend to prioritize. Energy efficiency, particularly from renewables like solar or wind, is a major consideration. The efficiency of a lithium ion battery stands at approximately 95%, markedly surpassing other battery types such as nickel hydrogen, which may only reach around 35% efficiency. Put simply, the ability to retrieve as much of the 100 kilowatt hours input into the storage system is crucial, and this is precisely what lithium ion batteries offer.
Another crucial characteristic is the cycle life of the battery. Lithium ion batteries are renowned for their capacity to attain up to 10,000 cycles, equating to a total lifespan of 10-20 years. Moreover, the rapid response capability sets them apart from alternatives such as pump storage systems, with lithium ion batteries able to respond in less than 10 milliseconds.
When considering the impact of higher energy density and efficiency of a battery storage technology on the levelized cost of energy (LCOE) for a utility or consumer, the advantages become apparent. The 320 Ah Wending battery, for instance, boasts a 15% increase in energy density compared to a traditional 280 Ah battery, enabling more energy to be stored using the same land area, ultimately reducing the overall system cost.
Furthermore, greater energy efficiency leads to higher energy output, thereby enhancing the return on investment. Additionally, it decreases heat generation and carbon emissions, establishing it as an environmentally conscious choice.
The advantages of these Wending battery cells for the grid are significant. The innovation in cell chemistry and structure enables Wending technology to be applied to any type of battery cell, rendering it suitable for both small and large scale projects connecting to the grid. As an energy storage system, it functions as a reservoir, aiding in grid balancing and stabilization, ultimately enhancing efficiency. The higher efficiency of Wending batteries allows for increased energy storage, thereby reducing the need for generation to meet peak demands, a win for the environment.
Looking ahead, the Wending battery cell technology is positioned to undergo further evolution over the next two to three years. Mass production for the 320 Ah cells has already been achieved within the last three years, and efforts are underway to enhance the battery storage capabilities from 320 Ah to 345 Ah, with production scheduled to commence in 2024. This innovation will extend beyond just lithium ion phosphate batteries, encompassing NCM batteries and electric vehicles.
How does the 320 Wending battery cell align with REPT BATTERO’s vision for the future of sustainable energy? The transition from 280 Ah cells to 320 Ah cells using Wending innovation can reduce carbon emissions by around 54 kilograms per cell over the entire lifecycle, perfectly in line with REPT’s ambition to fuel a greener future for our planet. The Wending technology plays a pivotal role in realizing this vision.
