Why IsoTES®?
IsoTES® (Iso Thermal Energy Storage), the unique technology of GIGAette, provides constant-temperature (isothermal) heat with a single tank
Isothermal Output
Constant-temperature (isothermal) output
Single Tank Design
Single tank instead of conventional two-tank TES
Cost & Footprint Reduction
Cuts CAPEX, OPEX, and footprint (often ~50%)
High Energy Utilization
High utilization of stored thermal energy (>80% for HTS-IsoTES®)
The Challenge We're Solving
Thermal Energy Storage Needs
Industries face critical challenges in storing and dispatching thermal energy effectively:
The IsoTES® Answer
GIGAette's IsoTES® delivers breakthrough solutions that address each challenge:
Heat Demand Without Storage
Heat is over half of final energy demand, but lacks efficient storage and dispatching systems to ensure energy competitiveness.
Efficient Storage & Dispatching
IsoTES® provides efficient thermal energy storage and dispatching systems that transform heat into a competitive energy asset with constant-temperature output.
Supply Volatility & Demand Flexibility
Renewable energy and waste heat are intermittent; high peak demand charges and inflexible consumption patterns increase costs and prevent stable operations.
Taming Volatility, Shaping Demand
IsoTES® converts intermittent renewable energy and waste heat into reliable, dispatchable thermal energy while enabling peak shaving, load shifting, and year-round stable operations.
Economic Barriers to Decarbonization
Traditional decarbonization solutions compromise economic competitiveness with high LCOS, short asset life, and increased OPEX.
Economic Decarbonization
IsoTES® achieves economic competitiveness through lower levelized cost of storage (LCOS), extended asset lifetime exceeding 30 years, and significantly reduced operational expenses.
New Industry Infrastructure Gaps
Emerging industries like SMRs, AI/data centers, and biomass processes lack reliable thermal infrastructure for heat and cold energy management.
Enabling New Industries
IsoTES® provides reliable thermal infrastructure to support emerging industries including small modular reactors, AI/data centers, and biomass processes for both heating and cooling applications.
Proven in the Field
Real-world deployments demonstrating proven performance
Our Technology
Revolutionary thermal piston technology enabling single-tank, constant-temperature thermal storage
Cell Structure
An IsoTES® tank consists of many small tanks called 'Cells', each maintaining different temperatures from neighboring cells.
Temperature Distribution
The temperature profile creates a step-like pattern with a sharp thermal stratification boundary between hot and cold zones.
Thermal Piston Effect
The stratification boundary moves dynamically during charging and discharging, acting like a thermal piston that pushes constant-temperature heat output.
(No physical piston exists—only the thermal piston effect)
