The Problem
The bottleneck in the AI era is not compute, but energy
AI data center power demand is surging, but grid expansion and infrastructure deployment are not keeping pace with that demand. EX-SMART CELL is a new energy deployment platform designed to solve power, cooling, and carbon challenges at the same time.
Surging power demand
As AI model training and inference workloads increase, data center power demand is expanding rapidly.
Mismatch in supply speed
AI demand is growing quickly, but power infrastructure deployment takes a long time, causing project delays.
Power density limits
AI racks require much higher power density and cooling performance than existing infrastructure.
Grid dependence risk
Grid saturation, renewable intermittency, and outage risk make stable AI infrastructure operations difficult.
Carbon regulation and ESG pressure
As Net Zero and Scope 2 reduction requirements increase, carbon-free power infrastructure is becoming essential.
Rising infrastructure costs
Power infrastructure represents a major share of data center investment costs and increases the CAPEX burden of new projects.
Fundamental Concept
EX-SMART CELL does not store electricity
It is not a concept that replaces conventional batteries and power generation systems, but an energy storage + conversion system that stores air (pressure) and converts it into electricity and cooling when needed.
It does not store electricity
It does not directly store electrical energy like a lithium battery.
It stores air (pressure)
It stores air in high-pressure tanks using a liquid-based compression method.
It converts it into electricity and cooling when needed
It generates electricity through multi-stage expansion and uses exhaust cooling for air conditioning.
Core Concept & Technology
Store air, and convert it into energy when needed
EX-SMART CELL rapidly charges air through liquid-based high-pressure compression, stores it in a high-pressure tank, and then converts it into electricity through a multi-stage expansion process. Air is a safe storage medium that does not combust and can provide both power and cooling.
1
01 — Charge
Liquid-driven air compression rapidly compresses air and charges energy.
2
02 — Store
The compressed air is stored in a high-pressure tank so it is ready for use when needed.
3
03 — Discharge
A multi-stage expansion engine converts compressed air energy into electricity and provides stable output.
4
04 — Cooling
Expansion exhaust cold energy is recovered to help support cooling demand in data centers and industrial facilities.
Technology Advantage
Air Battery that goes beyond the limits of Battery ESS and CAES
EX-SMART CELL is a new energy infrastructure category that combines low fire-risk air storage, long-life architecture, modular scalability, low-noise and low-vibration design, and cold-energy recovery.
Zero fire-risk aspiration
Because air is used as the storage medium, the structure significantly reduces fire risk compared with conventional lithium battery ESS.
Multi-stage Expansion Engine
Applies core technology that converts compressed air energy into electricity through the EX-1 multi-stage expansion engine.
Precision Pressure Control
Stably controls pressure flow through the EX-V precision pneumatic control valve.
Cold Energy Recovery
Through the exhaust cold-energy recovery system, it can be used not only for power but also for cooling infrastructure.
Low Noise & Anti-Vibration
Targets installation suitability for industrial facilities and data center environments through an integrated low-noise, low-vibration structure.
Scalable Architecture
Designed to expand modularly to match project scale, from kW-level to MW-level.
Data Center Strategy
An integrated power + cooling energy platform for AI data centers
Solves the power and cooling challenges of AI data centers with a single system.
Integrated power supply + cooling
Provides carbon-free power supply and cooling based on exhaust cold energy recovery in one system.
PUE improvement potential
By integrating power and cooling infrastructure, it aims to improve data center operating efficiency.
Supports Scope 2 reduction
The carbon-free, non-combustion power supply structure can be linked to data center carbon reduction strategies.
EaaS long-term revenue model
An Energy-as-a-Service model can be structured as a 15–20 year long-term energy service contract.
Infrastructure Advantage
With less resources, higher power density
EX-SMART CELL implements high-density energy infrastructure based on miniaturized, high-efficiency equipment, reducing site acquisition and construction costs. This is the technological and strategic optimization of power CAPEX to build a more stable and sustainable power environment with fewer physical resources.
Reduced site cost
Miniaturized, high-efficiency equipment minimizes the installation footprint for the same output.
Construction cost optimization
The modular structure enables rapid deployment without complex civil or construction work.
Strategic CAPEX optimization
Maximizes infrastructure investment efficiency by increasing power control capability per unit area and investment.
Business Model
From product sales to a long-term cash flow energy platform
EX-SMART CELL stores renewable energy as compressed air energy and is deployed across industrial ESS, data center LDES, and residential EX-cell HOME to simultaneously deliver power stability, cooling efficiency, CAPEX optimization, and carbon-neutral value as an Air Battery-based Net-Zero Power Platform.
