Thermal Energy Storage (TES)

Thermal energy storage turns low-cost electricity, including surplus wind and solar and off-peak grid power, into stored heat that can be used on demand for industrial processes.

Thermal energy storage turns electricity into stable, controllable energy that can be dispatched exactly when your plant needs it.

During low‑cost or low‑carbon hours, the system uses electric heaters or heat pumps to charge insulated tanks or high‑temperature “thermal batteries,” raising the temperature of water, thermal oil, bricks, sand, or specialized materials.

Once charged, that stored heat is metered out through heat exchangers into existing hot‑water, steam, or thermal‑fluid circuits, supplying CIP loads, wash water, drying, or other thermal processes without touching your production schedule.

Controls coordinate charging with power prices and your heat demand profile, so you see a consistent, predictable heat supply. At the same time, the storage absorbs price volatility, reduces boiler runtime, and cuts emissions.

Industrial Heat Pumps

Industrial heat pumps use electricity to recover waste heat already on your site and convert it into useful process heat, hot water, or cooling.

Industrial heat pumps use electricity to upgrade recoverable low‑temperature heat from your site into useful process heat, hot water, or steam.

Waste heat from process units is routed to the evaporator, where a working fluid absorbs that heat and evaporates. A compressor then uses electricity to raise the fluid to a higher pressure and temperature, and in the condenser, that upgraded heat is converted into useful thermal energy.

The cycle runs continuously under automated control, modulating capacity to your production load so that every kilowatt of reclaimed waste heat reduces fuel consumption.

The result is a tightly integrated piece of process infrastructure that lowers energy costs and emissions while improving operational safety.

Electrode Boilers

Electrode boilers produce steam or hot water by passing electricity directly through water, using its natural resistance to generate heat quickly and efficiently without burning fuel.

Electrode boilers provide direct, high‑temperature steam by passing an electric current through water.

Treated feedwater enters a pressure vessel where it contacts submerged electrodes supplied with high‑voltage power.

The water’s electrical resistance converts this power into steam.

Steam is separated from the water, regulated by pressure and flow controls, and then delivered into your existing steam header or hot‑water loop.

With no burners, flues, or fuel trains, the boiler room becomes simpler to operate and maintain, while the electrical input can be paired with clean power to deliver clean steam.

TES + Steam Turbine

Thermal energy storage paired with a conventional steam turbine generator turns stored heat into on-site electricity, giving industrial facilities direct control over their power costs. By sourcing low-cost off-peak or curtailed electricity – stored as heat – Zero Industrial can offer innovative power solutions for large load customers in grid constrained environments.

During off-peak or low-cost hours, the thermal energy storage unit draws electricity from the grid and converts it into stored heat.

When power is most expensive or most needed, that stored heat generates clean steam at temperatures and pressures suitable for driving a conventional steam turbine generator.

The dispatch cycle can be timed to coincide with peak pricing windows or grid reliability events, giving the facility economic optionality that a grid-only supply cannot match.

Where process heat is also needed, steam can be routed to downstream heating loads rather than condensed, extracting additional value from each charge cycle. System sizing and dispatch strategy are engineered to each facility’s specific load shape and tariff structure.
