In the exhibition hall of the 2025 Asia Power Energy Storage Exhibition, the booth of Guangzhou Mayer Energy Storage Technology Co., Ltd. was bustling with visitors. Its exhibited phase change energy storage boxes and diversified cold/heat storage solutions, covering scenarios such as data center waste heat recovery, constant temperature in agricultural greenhouses, and energy conservation in commercial buildings, became the focus of the exhibition. The parent company of this energy storage technology firm—a Hong Kong-listed company (stock code: 01116.HK) that once focused on stainless steel pipes and carbon steel cutting and distribution—has quietly completed its brand transformation: in June 2025, the company officially adopted the new name "Huiyuan Cowins Technology Group Co., Ltd.", with its stock short name updated to "Huiyuan Cowins Technology" simultaneously. At the same time, the company relocated its headquarters to World Trade Center in Causeway Bay, Hong Kong, to get closer to international capital and technological resources, paving the way for global layout. This rebranding is not just a change of brand identity, but a strategic leap from traditional manufacturing to the smart energy storage technology field.

From "Guangzhou Mayer" to "Huiyuan Cowins Technology": The Strategic Significance Behind Brand Iteration

In April 2025, the company's Extraordinary General Meeting of Shareholders passed the rebranding resolution with a high vote; in May, the Cayman Islands and Hong Kong Companies Registry completed the registration of the name change; on June 27, the Hong Kong Stock Exchange officially adopted the stock short name "Huiyuan Cowins Technology", with the stock code 01116.HK remaining unchanged, marking the conclusion of this two-month brand upgrading.

"This is not only an update of corporate image and geographical location, but also a symbol of our firm commitment to the path of innovation, collaboration, and high-quality development," emphasized Dr. Perry Ip, Chairman of Huiyuan Cowins Technology Group, in his public speech. The new name "Huiyuan Cowins Technology" embodies profound strategic considerations: "Hui" (wisdom) represents gathering global wisdom to overcome energy storage technology challenges; "Yuan" (source) points to the core track of the energy revolution; "Cowins" (co-creation) highlights the company's open philosophy of building a cooperation platform involving governments, research institutions, finance, education, and enterprises. The core driver behind the rebranding lies in the qualitative change of its business landscape. Since its establishment in 1995, the company has become an industry leader in traditional businesses such as stainless steel and carbon steel. Since 2023, it has successively established professional R&D institutions and launched multiple benchmark energy storage projects, achieving breakthroughs in the field of phase change energy storage. The original name could neither carry the new positioning of "technology + green" nor avoid brand confusion due to the universality of "Mayer" in multiple industries, while the new name accurately conveys the company's strategic direction of upgrading to the smart energy field.

Smart Energy Storage as the Second Growth Curve: Technological Breakthroughs and Scenario Implementation

In the smart energy storage track, Huiyuan Cowins Technology has built solid technical barriers relying on phase change energy storage technology (PCM) as its core, forming a solution matrix covering industrial, agricultural, and commercial scenarios.

In the industrial field, phase change energy storage technology provides an efficient solution for temperature regulation in constant temperature and humidity factories. By storing energy using low-cost electricity during off-peak hours and releasing it during peak hours, the technology not only achieves peak shaving and valley filling to significantly reduce enterprise electricity costs, but also precisely maintains a stable temperature and humidity environment inside the factory, reducing frequent start-ups and shutdowns of traditional temperature control systems. This improves the overall system energy efficiency by over 30%, significantly lowers energy costs, and helps enterprises save energy and increase efficiency.

In agricultural scenarios, phase change energy storage technology is combined with data center waste heat and solar energy to open up a new path for heating agricultural greenhouses. A large amount of waste heat generated by data centers is recovered and stored in phase change materials together with solar energy, which stably releases heat at night or in insufficient light to provide continuous heating for greenhouses. This not only solves the problems of high energy consumption and large temperature fluctuations in traditional heating methods, but also keeps the temperature in greenhouses within the optimal range for crop growth, effectively extending the planting duration and practically helping agriculture increase production and income.

In the commercial field, the integration of data center waste heat recovery and phase change energy storage technology provides a green solution for heating residential communities and cooling/heating regulation in shopping malls and other places. The recovered waste heat from data centers is processed and then realizes efficient energy storage and release through phase change energy storage equipment, providing stable heating for communities in winter and meeting the cooling needs of commercial places such as shopping malls through peak shaving and valley filling in summer. This model replaces part of traditional gas or electricity supply, reducing energy costs for commercial operations while cutting carbon emissions, achieving a win-win situation of economic and environmental benefits.

Market Prospects: Dual Drivers from Policies and Demand

At the policy level, all scenarios have received precise support: in the industrial field, the 14th Five-Year Plan for Comprehensive Energy Conservation and Emission Reduction Work requires promoting energy-saving and carbon-reducing actions to make data centers and other facilities meet the energy efficiency benchmark level accounting for over 30%, providing an application foundation for technologies such as waste heat recovery; in agricultural scenarios, the National Modern Facility Agriculture Construction Plan (2023–2030) proposes popularizing energy-saving and consumption-reducing technical equipment to help improve resource utilization in facility agriculture, paving the way for heating solutions combining phase change energy storage with waste heat and solar energy; in the commercial building field, the Carbon Peak Implementation Plan in Urban and Rural Construction clearly states that newly built urban buildings will fully implement green building standards by 2025, encouraging the development of zero-carbon buildings, thus providing space for the application of phase change energy storage in energy efficiency improvement.

The demand side shows structural growth: data center energy consumption continues to rise. According to data from the National Energy Administration, power consumption reached 270 billion kWh in 2022 (accounting for 3.1% of the national total), with an average annual growth rate of about 15% from 2022 to 2025, driving the rapid expansion of the waste heat recovery market. The Research Report on China's Data Center Waste Heat Recovery Technology Market released by the China Center for Information Industry Development (CCID Consulting) in 2023 points out that the special market scale of data centers will exceed 8 billion yuan by 2025, and the overall industrial market is expected to exceed 80 billion yuan; the area of facility agriculture exceeds 40 million mu. Combined with the Report on the Application Prospects of Energy Storage Battery Thermal Management Systems in Smart Agriculture (2025) and local policies, "demand for intelligent temperature control drives the agricultural energy storage market to grow by 20% annually"; the energy-saving renovation market for commercial buildings expands by 18% annually. The 2024 Research Report on Carbon Emissions in China's Urban and Rural Construction released by the China Building Energy Conservation Association shows: "Carbon emissions from the construction sector accounted for 48.3% of the national total in 2022, and the building energy conservation market scale is expected to exceed 300 billion yuan by 2029." The widening peak-valley electricity price difference further increases the penetration rate of energy storage technologies, and multiple demands jointly open up growth space for smart energy storage.

Relying on its technological and project accumulation in the three scenarios of industrial waste heat, agricultural temperature control, and building energy conservation, the company plans to occupy 5%–10% of the phase change energy storage segment market in the next three years, creating a unique growth path deeply bound to application scenarios and injecting new impetus into industry development.

Strategic Outlook: Technological Iteration and Global Layout in Parallel

"In the next three years, we will invest more resources in PCM technology iteration, production line upgrading, and global market expansion," revealed Dr. Perry Ip. The company plans to deepen research and development in collaboration with institutions such as the Chinese Academy of Sciences and China Agricultural University, while expanding production capacity to meet the explosive demand in industrial, agricultural, and commercial scenarios, with the goal of becoming "a globally leading energy storage technology provider."

Industry insiders pointed out that from "making good pipes and transporting good water" in stainless steel pipes to "efficient heat storage and green carbon reduction" in phase change energy storage, Huiyuan Cowins Technology's rebranding and transformation is not only a response to the global low-carbon wave but also a microcosm of the upgrading of traditional manufacturing to high-tech services. In this energy revolution, every layout of this Hong Kong-listed company is reshaping the competitive landscape of the smart energy storage industry.
