Multi-Pronged Deployment,: Everdura's Win–Win Strategy and Global Strategy

Vanadium redox flow batteries are distinguished by their inherent safety—designed to avoid ignition and combustion—and they offer an exceptionally long operational lifespan. Additionally, more than 99% of their constituent materials are recyclable, underscoring their significant environmental benefits.

Since its official establishment in 2022, Everdura—under the leadership of CEO Brian Tseng—has rapidly emerged as a market standout. Initially formed as a joint venture between Everbrite and Pronergy Tech, the company's roots can be traced back to 2015 when it entered the energy-saving business. Over time, it expanded into system integration and, recognizing the rapid global rise of the virtual power plant industry, ventured into the energy storage market in 2019. Reflecting on the company's founding, Tseng noted that the extensive industry experience, technical expertise, and resource networks accumulated by both parent companies provided a crucial foundation for Everdura. "Although we are a startup, we already possess a wealth of resources and technical know-how," he added.

"Ten years ago, I transitioned from the telecommunications industry into the energy sector and embarked on my mid-career entrepreneurial journey. At that time, while telecom was maturing, the energy industry still held vast potential, " said Tseng. In its early days, Everdura's client base primarily comprised entities requiring energy-saving solutions—ranging from Carrefour hypermarkets to hospitals and hotels. By 2021, the company had attracted the attention of additional enterprises.

"Many companies have shown strong interest in the lithium-ion and vanadium redox flow batteries we represent, and several publicly listed firms proactively approached us for further collaboration. Among these, Everbrite not only provided financial support but also invested team resources—leading us to form a joint venture with them. From initial discussions to the decision to establish the joint venture, the entire process took merely three months, which speaks volumes about our shared objectives and operational efficiency," Tseng explained.

Everdura has concentrated on two core segments: net-zero buildings and energy-related sectors. "Net-zero buildings are our primary priority, and we have received tremendous support from institutions such as PJ Asset Management Group, various developers, and other partners. Our revenue is gradually showing positive results; by 2025, the total value of orders and projects under design is expected to exceed NT$700 million, and we anticipate exponential growth in the coming years," Tseng asserted.

While the company initially centered its efforts on the Taiwanese market, it has also received partnership invitations from companies in several Southeast Asian countries, Australia, and the United Kingdom. "Over the next two years, we will gradually integrate our energy and net-zero building sectors and further expand into the international market. We aim to contribute to the planet and society amid the global trends of net-zero emissions, virtual power plant development, and ESG-driven circular economy—while ensuring that the interests of the state, our clients, and our employees are balanced to create a win–win scenario," he emphasized. Tseng made it clear that this philosophy is not just an abstract idea but a concrete operational guideline.

Diverse Deployment: From Representation to In-House R&D and Investments

From its inception, Everdura set its first-phase targets across a wide spectrum—from energy creation, energy saving, and energy storage to system integration, eco-friendly gas-insulated switchgear, and net-zero buildings—while also exploring adjacent sectors. In addition to securing representation and technology transfers from various domestic and international manufacturers, the company has concurrently embarked on in-house research and development and strategic investments to secure critical core resources. "Our portfolio may appear diverse, but it is all centered on the common goal of achieving net-zero emissions, advancing ESG initiatives, fostering the circular economy, and developing virtual power plants," Tseng summarized.

In the realm of net-zero building services, Everdura places special emphasis on both net-zero/smart buildings and smart homes. "At this stage, in the net-zero/smart building arena, we have integrated multiple technologies—including a building management system for net-zero/smart buildings, community low-voltage systems, Busway busbars, electric vehicle charging stations, and an EMS energy management system. We have also incorporated solutions for mobile communications enhancement, electric vehicle fire blankets, access control intercom and surveillance systems, as well as decentralized virtual power plant applications," Tseng explained.

For smart homes, the company's service blueprint encompasses products such as electronic locks, anti-smog window screens, fresh air systems, and water filters, with ongoing development of additional solutions. "Our goal is to ensure that residential environments are both comfortable and convenient while adhering to the principles of ESG sustainability. By integrating these services and products, we align residential living with the objectives of a circular economy and net-zero emissions," he added.

Everdura also boasts a robust presence in the energy services sector. "We are not only the representative for Panasonic's lithium-ion battery energy storage systems, but we also provide integrated services to EPC (Engineering, Procurement, and Construction) and SI (System Integration) companies. This includes developing dedicated ESS controllers and energy storage cabinets to create customized solutions. Moreover, since 2022, we have been actively negotiating with INVINITY. In December 2022, we officially secured the sales agency rights for their vanadium redox flow battery energy storage system, and by February 2024, we obtained manufacturing authorization. This enables us to sell and produce the system in most global regions as we actively build a virtual power plant ecosystem," Tseng detailed.

Lithium-ion batteries have long faced criticism for potential hazards and their relatively short lifespans—especially from an ESG perspective. "The low recycling rate of lithium-ion batteries undermines their environmental benefits. In contrast, vanadium redox flow batteries do not pose fire risks, have an exceptionally long lifespan, and over 99% of their materials are recyclable. In the context of a circular economy, these batteries offer significant advantages in carbon footprint management and ESG reporting, making them an extremely attractive option," he noted.

Everdura plans to establish a comprehensive upstream supply chain in Taiwan and invest in the production of vanadium redox battery modules, with the goal of transforming Taiwan into a global manufacturing hub. "After discussions with the original manufacturer, we realized that lithium-ion and vanadium redox flow batteries are not competitors but rather complementary technologies. Lithium-ion batteries are power-type—ideal for short-duration, high-output demands—whereas vanadium redox flow batteries are energy-type, suited for long-duration, stable output. Recognizing the need for varied energy storage solutions across different applications, we have introduced a hybrid energy storage solution (Hybrid ESS) that combines both battery types," Tseng emphasized.

Currently, Everdura has launched a grid-connected hybrid energy storage project in central Taiwan and plans to complete the site's construction within the year. "Two years ago, we successfully implemented behind-the-meter hybrid energy storage technology in Guanyin, Taoyuan—making us one of the few companies in Taiwan to bring this technology to fruition," Tseng added.

On another front, the company is developing eco-friendly gas-insulated switchgear (ECO C-GIS) to replace sulfur hexafluoride (SF₆). Given that SF₆ is one of the most harmful greenhouse gases—with a global warming potential over 23,500 times that of CO₂—and plays a critical role in power systems, international trends call for its phase-out beginning in 2026. In response, Everdura has signed a technology transfer memorandum with prominent heavy electrical equipment manufacturers from Japan and Germany and is planning to design and produce eco-friendly switchgear that meets the specifications of both Taiwan and Southeast Asia.

Multi-Front Operations: Persistence Amid Challenges

"Breaking into the market as a startup is never easy, and we found ourselves simultaneously confronting challenges across multiple domains," Tseng candidly remarked. The company faced hurdles in promoting net-zero buildings, managing fluctuations in lithium-ion battery prices, negotiating technology licenses for vanadium redox flow batteries, and forging technical collaborations in eco-friendly gas-insulated switchgear—all of which exerted unprecedented pressure.

In promoting net-zero buildings, one of the initial challenges was overcoming construction companies' skepticism toward new technologies. "Due to the long project cycles in the construction industry—where each project must undergo multiple rounds of evaluation—we spent over a year engaging in repeated discussions with potential partners before successfully entering the market," Tseng explained.

In the lithium-ion battery market, fierce competition from Chinese manufacturers led to a continuous decline in global battery prices. "Our existing inventory suffered impairments, directly impacting our financial statements. Nonetheless, we maintained a long-term perspective in the energy storage market, continuing to invest funds and resources to secure a competitive advantage for the future—even by channeling resources into the development of more cutting-edge technologies," he recalled.

Tseng observed that while regions such as Europe, the United Kingdom, and France have aggressively pursued hybrid energy storage, Taiwan's progress remains in its early stages. International studies indicate that as renewable energy and fast-charging EV stations become more prevalent, the complexity and flexibility requirements of grid dispatch will multiply. Traditional grid management—characterized by predictable, fixed consumption patterns in industrial settings—will be challenged by the unpredictable usage and location patterns of EV charging stations. "If we can deploy hybrid energy storage systems at decentralized charging stations or substations to dynamically manage power-type and energy-type storage based on demand, we can not only alleviate grid pressure but also enhance overall efficiency. This is a key component of virtual power plants (VPPs). Currently, while Europe and mainland China are already testing and implementing such systems, our company is the first in Taiwan to put hybrid energy storage into practical use," Tseng said with evident pride.

Vanadium redox flow batteries have been a flagship project for Everdura over the past several years—a challenging journey that saw the company secure sales agency rights from INVINITY in December 2022 and obtain manufacturing authorization in early 2024. "We had to demonstrate unwavering determination and ambition, engaging in continual negotiations with INVINITY's top management. Once the contract was established, the subsequent stages—site selection, facility leasing, factory registration, production line planning, and equipment procurement—proved extremely complex, but we overcame each challenge step by step," Tseng remarked.

Regarding the development of eco-friendly gas-insulated switchgear, after years of persistent negotiations, Everdura signed cooperation agreements in 2024 with leading heavy electrical equipment manufacturers from Japan and Germany. With comprehensive planning and design of the production line complete—and backed by significant early-stage technical research and the mutual trust built with its partners—the project is progressing smoothly and is expected to enter trial production in 2026.

The implementation of distributed energy storage and VPPs is an inevitable trend. Relying solely on centralized grid resources will not meet the future demands for flexibility and efficiency in energy dispatch, while the private sector, with its abundant resources, can serve as an ideal complementary force if properly harnessed (The left image shows the process of electrolyte quality sampling for a vanadium redox flow battery system, while the right image features a project site for a hybrid energy storage system that integrates lithium-ion batteries with vanadium redox flow batteries.).

From Domestic Trials to Overseas Deployment: Everdura's Global Strategy

"We plan to establish a grid-connected hybrid energy storage system in central Taiwan that integrates Panasonic lithium-ion batteries with INVINITY's vanadium redox flow batteries, thereby participating in Taipower's enhanced dynamic frequency regulation and spinning reserve ancillary services (E-dReg)," Tseng stated confidently.

As renewable energy and fast-charging EV stations proliferate, the demands on grid dispatch are growing ever more complex. The complementary characteristics of lithium-ion and vanadium redox flow batteries—each excelling in different applications—mean that their coordinated use can significantly improve dispatch efficiency and extend system longevity. "In 2023, we built a behind-the-meter hybrid energy storage system for testing. However, due to lengthy local government permitting procedures, the grid-connected system's commissioning has been delayed until the second half of 2025. We have partnered with domestic firms experienced in energy management system development and plan to apply for industry certifications as we jointly develop a comprehensive energy management solution for hybrid storage—with the long-term goal of exporting complete systems overseas," Tseng elaborated.

Discussing industry deployment and policy support, Tseng pointed out that regulations often lag behind market demand and technological innovation. "If policies are delayed too long, many small- and medium-sized enterprises with limited capital may not be able to sustain operations—even if they possess vision and ambition—forcing them to exit the market. For example, under the Renewable Energy Development Act, although the standby capacity policy was only recently announced, the issue of large power users had been on the radar four or five years ago. Many companies with limited capital could not endure until now, leaving the market in need of new teams to fill the void."

"Distributed energy storage and virtual power plants represent an inevitable trend. Relying solely on centralized grid resources will not meet the future needs for flexibility and efficiency in energy dispatch. Meanwhile, the private sector possesses abundant resources which, if properly harnessed, can serve as a crucial supplementary force. For instance, lowering the threshold for large power users from 5,000 kW to 800 kW would encourage companies to adopt more proactive energy strategies and stimulate market investment," Tseng noted.

"Moreover, if Taiwan aspires to secure a position in the international market, it must adopt a forward-looking approach. By developing more advanced technologies ahead of other countries, we can not only implement them domestically but also export them overseas," he added. Although Taiwan may trail Europe and the United States in certain technological areas, it still holds a competitive edge in the Asia–Pacific region—and its overseas market potential is vast. "We have already received strong support from many partners. For example, last year we collaborated with several publicly listed domestic EPC firms to negotiate projects in Southeast Asia, aiming to join forces with more industry partners to expand our international footprint," Tseng explained.

While the Taiwanese market remains its core focus, Everdura is actively pursuing international expansion. "In the future, we intend to use Taiwan as a base to continue cultivating the ESG sector, participate in a variety of ancillary services—including intraday and real-time imbalance markets—and work diligently to export our technologies and products overseas, all while moving toward becoming a global leader," Tseng stated.

"Being a startup does not equate to being small in scale or lacking resources—it signifies unlimited potential. Our mission is to seize emerging trends and focus on technology to accelerate and extend the journey toward net-zero emissions." These words encapsulate Everdura's remarkable achievements in such a short time. As the company continues to evolve across multiple domains, we may well witness more Taiwanese enterprises making significant contributions on the global stage of net-zero transformation.

According to Tseng, being a startup does not equate to having limited scale or resources—it represents boundless possibilities. Everdura is focused on capitalizing on emerging trends and honing its technological expertise to accelerate and extend the journey toward achieving net-zero carbon emissions.
