Securing Energy Infrastructure: ETICA Wins Japan's First Commercial Immersion-Cooled Energy

Storage Project Amid growing geopolitical uncertainties and the ongoing restructuring of global supply chains, Japan has accelerated efforts to strengthen grid resilience and expand localized microgrid infrastructure as part of its long-term energy security strategy. However, the country's dense urban environment and high seismic activity have resulted in some of the world's most stringent fire safety regulations governing large-scale energy infrastructure.

Conventional air-cooled and water-cooled BESS have faced significant deployment challenges in Japan due to concerns over thermal runaway propagation and fire safety risks, particularly in densely populated regions. Against this backdrop, ETICA formally signed a MOU with a leading Japanese green energy developer on June 2, establishing a strategic partnership to advance the deployment of Japan's first commercial immersion-cooled energy storage facility. The two parties plan to complete contractual procedures by Q3 2026 for a project with a total installed capacity of 4MW / 16MWh.

The project represents a major milestone for Taiwan's green energy technology sector and highlights the growing international recognition of advanced energy storage solutions developed in Taiwan.

At the core of the project is ETICA's proprietary LiquidShield™ platform, designed around the principle of intrinsic physical safety. By fully immersing battery cells in a specially engineered dielectric cooling fluid, the system provides continuous thermal management and immediate heat absorption under abnormal operating conditions. Even in extreme scenarios, such as internal short circuits triggered by severe seismic events, the system can rapidly suppress heat accumulation, prevent thermal runaway propagation, and significantly reduce the risk of battery reignition.

The deployment will mark the first commercial application of full-immersion energy storage technology in Japan, setting a new benchmark for safety and reliability in the country's energy storage market. More importantly, the project strengthens ETICA's position within the emerging Asia-Pacific resilient and diversified supply chain ecosystem, establishing a strategic foothold in one of the world's most demanding energy infrastructure markets.

As governments and industries increasingly prioritize energy security, grid resilience, and critical infrastructure protection, the partnership is expected to serve as a model for the next generation of safe and sustainable energy storage deployments across the region.

Chairman of ETICA stated: "The MOU signed today with our Japanese partner represents far more than a commercial order for ETICA. It is compelling evidence that Taiwan's advanced energy storage technology has earned recognition under some of the world's most rigorous safety standards.

While global industry leaders gathered at COMPUTEX are focused on advancing AI computing power and next-generation digital infrastructure, we firmly believe that sustainable computing begins with secure and reliable energy. Without absolute power safety, there can be no sustainable computing capacity.

ETICA's power architecture for future AI Data Centers (AIDCs) demonstrates our ability to bridge the energy and digital economies. By placing intrinsic safety at the core of our innovation strategy, we are building a green energy platform capable of delivering value across multiple high-growth industries. This project marks another important step in transforming advanced energy storage technology into critical infrastructure for the AI era."

Representative of the Japanese Energy Developer commented: "The Japanese market maintains exceptionally stringent requirements for the safety of power infrastructure. As the nation accelerates its energy transition and grid resilience initiatives, we have been actively seeking technologies capable of delivering both high energy density and uncompromising safety within a demanding regulatory environment.

ETICA's LiquidShield™ immersion cooling platform fundamentally addresses our concerns regarding thermal runaway risks in BESS. The technology's intrinsic safety characteristics provide a level of confidence rarely seen in the industry.

The signing of this 4MW / 16MWh project is only the beginning of what we expect to be a long-term strategic partnership. Together, we have already established a roadmap for future collaboration and plan to advance large-scale immersion-cooled energy storage deployments across Japan, targeting a cumulative installed capacity of approximately 1.6GWh over the coming years.

We believe that Taiwan's innovative approach, combining industry-leading safety standards with AI-driven energy management capabilities, will become a critical enabler of Japan's next-generation microgrid transformation and energy resilience strategy."

Advancing Beyond Battery Innovation: ETICA Unveils Its Vision for Future AIDC Power Architecture

According to projections from international energy agencies, the rapid evolution of AI servers is driving exponential growth in rack-level thermal design power (TDP), placing unprecedented demands on power delivery infrastructure. As next-generation AI workloads continue to scale, ensuring stable and resilient power supply is becoming as critical as the advancement of computing hardware itself. Recognizing this industry transformation, ETICA has introduced its vision for a high-resilience power architecture designed specifically for future AIDCs.

In the emerging era of AI factories, the training of large-scale foundation models and trillion-parameter AI systems will generate massive, highly dynamic computing loads. These workloads can create millisecond-level power fluctuations that place significant stress on utility grids and facility power systems. Without an ultra-stable power buffering mechanism, such fluctuations may accelerate the degradation of high-value semiconductor assets, reduce operational efficiency, and potentially disrupt mission-critical computing operations.

To address these challenges, ETICA is developing a next-generation power infrastructure framework that integrates advanced energy storage directly into AI computing environments. In addition to collaborating with customers on the adoption of 800V DC architectures to improve energy efficiency and reduce transmission losses, the company envisions its proprietary immersion-cooled energy storage systems serving as the foundational "power buffer" for future AI facilities.

Unlike conventional uninterruptible power supply (UPS) systems, which are primarily designed for short-duration backup protection, ETICA's zero-latency battery output architecture is engineered to provide continuous power stabilization. The system can instantaneously compensate for voltage sag events, smooth power fluctuations, and deliver highly stable current to support demanding AI workloads.

By converging energy storage, intelligent power management, and AI infrastructure into a unified architecture, ETICA aims to establish a new paradigm for energy-compute integration. The approach is designed not only to enhance operational reliability and energy efficiency but also to support the long-term scalability of next-generation AI data centers.

Several overseas data center operators have already expressed interest in adopting the company's integrated energy-and-computing design philosophy, with pilot deployments and validation programs expected to commence within this year.
