Thermal storage research • Gen-1

Heat,
rethought.

A compact phase-change thermal battery designed around one deliberate rule: keep the salt stationary and keep the working-fluid channels clean.

CLEAN WATER / GLYCOL ONLY
From our thermal lab

Start with the failure modes. Design them out.

Salt hydrates offer attractive thermal density, but corrosion, phase separation, crystal growth and poor heat transfer can undermine a small consumer product. HeatCell Mini Gen-1 is being engineered around those realities instead of hiding them.

The latest design decision

We took the salt out of the microchannels.

The internal microchannels carry only clean working fluid. The phase-change material remains stationary outside two sealed 316L exchanger plates. Heat crosses the wall; the materials never mix.

Technology

Built layer by layer.

Clean-fluid microchannels

Twelve parallel channels per exchanger plate carry approved water/glycol—not PCM—so salt precipitation cannot block the hydraulic path.

Containment first

A sealed PCM cartridge sits inside separate secondary containment with leak sensing and fault response designed into the system architecture.

Graphite-enhanced heat paths

Graphite-rich interfacial regions are being evaluated to shorten the conductive path through stationary PCM while controlling viscosity and segregation.

Application

Put stored heat where the house can use it.

HeatCell Mini is not trying to replace a whole-home electrical battery. It is being developed as a modular thermal buffer for loads that already need heat.

Hydronic heatingWater preheatHVAC bufferingHeat recovery

Shift small heating loads.

Charge from an approved heat source, hold thermal energy in the PCM, and release it later through the closed water/glycol loop.

Preheat before the water heater.

An isolated thermal loop can transfer stored heat into an approved preheat exchanger without exposing potable water to PCM chemistry.

Buffer heat-pump operation.

Thermal storage can be placed between generation and delivery to explore load shifting, cycling reduction and thermal smoothing.

Capture heat that would be discarded.

The same architecture can accept compatible waste-heat sources where the temperature window matches the selected PCM formulation.

How the system works

Charge. Hold. Release. Protect.

01 / CHARGE

Move heat in

Clean fluid enters the buried exchanger channels and transfers heat across the coated metal wall.

02 / STORE

Change phase

The stationary salt-hydrate PCM absorbs latent heat as it moves through its designed transition range.

03 / RELEASE

Move heat out

The thermal gradient reverses and stored heat returns to the working-fluid circuit.

04 / PROTECT

Fail safely

Temperature, flow and leak monitoring are intended to inhibit charging and isolate the module when faults are detected.

Validation program

The product earns its claims.

The launch site will distinguish clearly between design targets and validated specifications. Capacity, cycle life, corrosion resistance, standby loss and safety claims will move to the specification sheet only after representative hardware passes the relevant test gates.

Engineering transparency

Targets are not test results.

We will publish the conditions behind thermal-capacity, standby-loss and cycling figures rather than comparing heat storage with electrical storage without context.

Serviceable by design

Replace the thermal core, not the whole system.

The cartridge architecture is being developed around inspection, traceability, controlled replacement and eventual reconditioning or materials recovery.

LIFETIME VALUE

Heat is valuable.
Especially when you stop wasting it.

HeatCell Mini can store compatible thermal energy from electric and non-electric sources, including heat pumps, natural-gas systems, solar thermal, recovered appliance heat, and other approved sources.

BUILT FOR THE LONG RUN

The cartridge can age.
The system doesn’t have to.

HeatCell Mini separates the reusable enclosure, controls, and thermal interfaces from the sealed PCM cartridge. The architecture is designed for service rather than disposal.
