Understanding the Dynamics and Future Trends in the Portable Energy Storage Industry
Overview of the Portable Energy Storage Industry
1. Introduction
The energy storage industry, especially the portable energy storage industry, has been attracting increasing attention worldwide due to its pivotal role in facilitating the development of smart electric grids and renewable energy. In recent years, China, as a major player in the energy sector, has made significant efforts in building a sustainable energy system and promoting the development of the energy storage industry.
The evolution of the portable energy storage industry in China can be divided into three stages: the foundation stage, the nurturing stage, and the commercialization stage.
During the foundation stage, the Chinese government focused on encouraging innovation in energy storage technology. In 2010, the 12th Five-Year Plan was issued, marking the first appearance of the term "energy storage" in national documents. This helped lay a solid foundation for the industry's development. The government also initiated China's first large-scale energy storage demonstration project, the "Zhangbei landscape storage demonstration project (2011)", integrating wind power generation, photovoltaic power generation, energy storage systems, and smart power transmission.
During the nurturing stage, the Chinese government issued more energy storage policies involving power system reform, ancillary services, technical R&D, and environmental protection. In 2014, the State Council officially issued the "Energy Development Strategic Action Plan (2014–2020)", proposing to build a clean, efficient, safe, and sustainable modern energy system. The government encouraged the application of large-scale energy storage systems and promoted the commercial development of China’s energy storage industry.
The commercialization stage witnessed a preliminary exploration period for the commercialization of the energy storage industry in China. The National Energy Administration promulgated the “Guiding Opinions on Promoting Energy Storage Technology and Industry Development (2017),” which first clarified the strategic position of energy storage. This stage saw the government actively promoting the commercialization of energy storage and focusing on large-scale and industrial development.
The public's attitude towards energy storage policies plays a crucial role in determining whether storage is widely accepted. A positive public sentiment towards energy storage policies is essential for promoting the development of the energy storage industry. In China, the public has shown more positive sentiment towards energy storage than negative sentiment, indicating a general recognition of the potential of the energy storage industry. However, the positive sentiment towards energy storage showed a decreasing trend, while the proportion of negative emotions gradually increased, indicating that there are still many obstacles to be overcome in the development of energy storage.
The development of the portable energy storage industry in China has experienced rapid growth in recent years, with the government playing a significant role in its promotion. However, there still exist challenges such as incoordination of policies and a lack of market mechanism. The government needs to introduce more policies concerning market mechanism, R&D, and subsidies to enhance the effect of energy storage policies and increase public recognition. By doing so, the energy storage industry in China can further develop and contribute to the global energy transition

Market Dynamics in the Battery Storage Technology Sector
The Battery Energy Storage System (BESS) market is expanding rapidly due to increasing demand for renewable energy, falling battery prices, and the growing need for energy storage solutions. The global BESS market size was valued at $9.21 billion in 2021 and is projected to grow to $31.20 billion by 2029.
One of the major factors driving the growth of the BESS market is the shift toward low carbon energy generation to reduce greenhouse gases emission. This shift has led to large investments in various battery energy storage systems across the world, especially in the residential, non-residential, and utility sectors.
In addition, the increasing global population, coupled with the growing initiatives to boost rural electrification, has increased the peak energy demand. The increased rate of urbanization and the introduction of infrastructure projects have also increased the power supply-demand from utilities.
Furthermore, the development of new and advanced BESS units is expected to play a significant role in industry dynamics. For instance, in March 2021, Tesvolt, a German storage system manufacturer, launched a technologically advanced product line TS-I HV 80 battery, primarily designed to shave load peaks and comply with the demand from business and industrial customers.
Despite the growth drivers, the BESS market also faces some challenges. The primary factor that hampers the BESS market growth is the requirement of substantial capital investments. These systems are mainly deployed for large BESS plants to cater to the energy demand at peak loads.
Another challenge is the lack of robust regulatory framework and market standardization. Without common manufacturing codes or standards developed for energy storage devices, each manufacturer is free to develop its internal standards, which could lead to compatibility issues during installations and maintenance.
Investments in the design and manufacturing of BESS devices are expected to significantly influence industry dynamics. The exponential demand for energy resources across developing and developed countries, combined with expanding measures to ensure energy security, is set to push the market growth. Furthermore, advancements in the rising integration of new power generation technologies and revamping existing foundations have increased the requirement for new grid systems with effective backup and peak load characteristics.
In terms of technology, lithium-ion batteries are currently the dominant technology in the BESS market due to their cost and performance advantages, deep discharge cycle life, energy and power density, and other attributes. However, other promising technologies like sodium-ion, sodium-sulfur, metal-air, and flow batteries are also emerging.
Based on type, the lithium-ion battery segment is projected to lead the industry and hold a significant portion of the global market during the forecast period. Demand for lead-acid batteries will be fostered by the transportation sector slated to grow exponentially at the end of 2029 due to increasing hybridization of vehicle fleets and their safe & reliable operations in rechargeable systems.
In terms of market segmentation, the battery energy storage market can be divided into three segments: front-of-the-meter (FTM) utility-scale installations, behind-the-meter (BTM) commercial and industrial installations, and BTM residential installations. The FTM utility-scale installations are expected to grow the fastest among these three segments
