"Matching storage" into a mystery, who to break the game?

The key to "carbon neutrality" lies in new energy, and the key to the development of new energy is energy storage.

At present, with the increasing proportion of wind power and photovoltaic power generation, the allocation of energy storage for "relying on the sky" new energy has evolved from a policy encouragement to a mandatory requirement. According to statistics, at present there are more than 24 provinces and regions have published the policy of allocating storage, the proportion of allocating storage is generally between 8% and 30%.

However, although "distribution and storage" is imperative, the high cost, hidden security risks and unknown profit model make new energy investors speak of "distribution and storage" headache. Is there a product that can solve the pain points of the industry?

In November 2022, Jiangsu TRW Energy Storage Co., LTD. (hereinafter referred to as "TRW") released "TrinaStorage Elementa", a ten-thousand-cycle liquid-cooled energy storage system. This product has shown unprecedented advantages in the four aspects of safety and reliability, high efficiency and return, ultra-long life and intelligent application, greatly expanding the application space of energy storage.

In particular, the ten-thousand-times cycle life of the system solves the pain point of energy storage economy to a large extent and lays the foundation for large-scale market-oriented application of energy storage, which has attracted high attention in the industry.

Technological progress is the driving force to promote the development of energy storage, and the coordination between cost and safety is the breakthrough of energy storage bottleneck. With the release of TRW 10,000 cycle liquid cooled energy storage system, there are plenty of reasons to believe that it is an expected and effective way to break the barriers of the industry and solve the pain points of "distribution and storage" with technology.

Solve the puzzle

In recent years, with the acceleration of the global process of "carbon neutrality", the energy storage industry has been developing in full swing.

Driven by demand, the price of lithium carbonate, the upstream raw material for energy storage systems, has soared from 50,000 yuan per ton at the beginning of last year to about 500,000 yuan now. At the same time, energy storage system cell costs have also risen by 28 to 30 percent. In addition, due to IGBT shortage, energy storage converters are also rising in price.

In summary, the current energy storage system construction cost has reached 1.6~2.4 yuan /Wh, and the average price has increased by 30% compared with 2021.

However, rising costs are not the biggest concern. The energy storage industry's frequent safety incidents are even more worrying. According to incomplete statistics from the American Electric Power Research Institute (EPIR), a total of 52 major fire and explosion accidents have occurred in the global battery energy storage system (BESS) since 2021.

Increasingly low economy and more and more safety accidents have become the "two mountains" blocking the development of the energy storage industry. All energy storage industry enterprises are trying to explore and hope to break the situation as soon as possible.

The launch of TrinaStorage Elementa, TRW's "ceiling level" product, is a timely solution to the industry's challenges.

The reporter learned that "TrinaStorage Elementa" adopted TRW's new generation of 300Ah dedicated energy storage battery, which has a cycle life of more than 12,000 times, and passed the harsh safety certification test of vehicle gauge level such as prick, squeeze and fall. In contrast, the current industry mainstream energy storage cell cycle is only 8000 times.

On the basis of "Trin-Core", "TrinaStorage Elementa" also adopts the comprehensive matrix sensor layout, multi-point temperature sampling, the new generation of liquid cooling integration technology and other advanced design, finally enabling "TrinaStorage Elementa" to have the ultra-high life of ten thousand system cycles. The life span of energy storage system and photovoltaic system is at the same level. And the number of cycles of the current mainstream manufacturers of energy storage system is only about 6000 times, the large gap can be seen from this.

With high cycle times as the core, "TrinaStorage Elementa" also synchronely applies highly integrated system design and intelligent and efficient temperature management system, which makes the overall KWH cost of "TrinaStorage Elementa" drop by up to 32% compared to the previous generation products!

It is worth mentioning that "TrinaStorage Elementa" not only greatly reduces the KWH cost, but also gives consideration to extreme security.

TRW Energy Storage team found that most energy storage system accidents are caused by thermal runaway, and what determines the probability of thermal runaway is product quality and management quality. To this end, TRW proposed a three-dimensional energy storage security guarantee solution of active fire protection and rapid isolation. It established AI cell health monitoring and early warning function for "TrinaStorage Elementa", designed pack-level fire protection, and reserved water fire protection in the system. Through the trinity of three-dimensional security protection, "TrinaStorage Elementa" can minimize the thermal runaway probability of energy storage system.

At this point, TRW Energy Storage in the spirit of "the simple man moves mountains", step by step, layer by layer, continuous technology overlay, integration of new products, finally dug a channel in the energy storage industry cost and safety "two mountains".

The launch of "TrinaStorage Elementa" is the product of years of accumulation of Trina solar energy.

In 2015, TRW Energy Storage was founded. Based on Trina Solar's more than ten years of technical standards and management experience, TRina Energy Storage started from a high starting point and quickly gained a firm foothold in the market. Over the years, TRW has done a large number of demonstration projects, and has a rich accumulation of technology and talent reserves.

In 2021, TRW strengthened the layout of energy storage cells and established the strategic positioning of "TRW Core". In the same year, its sales exceeded 100 million yuan, and it ranked among the "top10 of China's energy storage system integrators in terms of newly installed units in China". By 2022, TRW's global reserves have reached 5GWh.

After a lot of accumulation and precipitation, TRINA Energy Storage successfully launched "TrinaStorage Elementa". This product further sets the industry benchmark for energy storage and provides a solution to the current focus of the energy storage market.

In the future

Since the beginning of this year, government departments have successively issued the Implementation Plan for the Development of New Energy Storage in the "14th Five-Year Plan", the "14th Five-Year Plan for Scientific and Technological Innovation in the Energy Field", the "Notice on Further Promoting the participation of New Energy storage in the power market and the dispatch and Application" and other documents, which reflects the national emphasis on the development of energy storage and lays the foundation for the great development of energy storage at the policy level.

In addition to the anticipated incremental market, the current inventory of energy storage projects is substantial. According to the statistics of Zhongguancun Energy Storage Industry Technology Alliance, the total scale of independent energy storage power stations planned, put into operation or under construction in 2021 exceeds 17GW/34GWh, involving more than 20 provinces and regions.

Such a huge market requires energy storage systems with higher economy and safety. In this regard, TRW energy storage related person told reporters: "We judge according to the market demand, 10,000 cycle liquid cooling system will become the mainstream product in the industry in the next 3 years."

At present, high-life energy storage system has become the inevitable direction to break the development bottleneck of the industry and increase the economy of energy storage. As the founder of this direction, TRW is still developing a new technology platform, and plans to further increase the number of cell cycles to more than 15,000, in order to further reduce the energy storage system's KWH cost, shorten the investment cycle, and is expected to start mass production in 2024. At that point, the energy storage industry is bound to take on a new level.

It is worth mentioning that TRW has been working on a global layout. Up to now, the company's global project reserves are widely distributed in China, the United States, the United Kingdom, Germany, Australia, Israel, Japan and other countries, which lays the foundation for the development of TRW Energy Storage in the global market.

"Following the launch of TrinaStorage Elementa, TRW has gained a lot of attention in the European and U.S. markets and is experiencing strong business growth momentum. Based on this, TRW has entered into strategic cooperation with Power Electronics, a global energy storage leader, to form a strong alliance. "On the one hand, it shows TRW's appeal in the overseas market. On the other hand, it also means that the new direction of energy storage development, 10,000 cycle liquid cooling system, will be led by Chinese companies in the future." TRW energy storage related person said.

In addition to the energy storage system, the relevant person of TRW Energy Storage also told the reporter that the underlying technology and concept of the "TRW core" with 12,000 cycle life used in "TrinaStorage Elementa" are portable and can be widely used in household energy storage, power battery systems, and even heavy cards. Commercial vehicles, electric ships, etc., to increase the economy and safety of these application scenarios.

In this regard, TRW has not only broken the barriers of the energy storage industry, but also developed and influenced many other industries in the future. The future market performance of "TrinaStorage Elementa" is worth looking forward to.
