THE CHALLENGE:

Energy intensity vs. volatility 

The chemical sector is the largest industrial energy consumer globally (IEA), with heat driving the majority of emissions. While critical units like distillation columns and continuous reactors demand absolute pressure stability, rising carbon taxes and volatile energy prices threaten margins.

The urgent task: Decarbonize thermal processes immediately, without sacrificing cost competitiveness or process integrity.

HEATCUBE:

Engineered for chemicals 

Heatcube is a thermal battery that replaces fossil dependency with precise steam delivery: low-pressure (2–5 bar) for evaporation or medium-pressure (6–15+ bar) for reaction dynamics.

This turns intermittent renewables into 24/7 baseload steam, shielding your margins from price spikes and turning decarbonization into a competitive advantage.

Engineered for chemical plant integration

Heatcube is a flexible thermal battery designed as a turnkey solution behind the meter. It integrates seamlessly with your existing steam infrastructure without disrupting downstream processes.

Step 1: Charge – Flexible intake

Charges on intermittent renewables or off-peak grid power. The system acts as an active grid asset, allowing you to monetize flexibility while securing energy savings.

Step 2: Store – The energy buffer

Energy is stored in non-flammable molten salt, creating a thermal buffer that decouples your steam supply from grid volatility and ensures uninterrupted heat.

Step 3: Discharge – Precise supply

Discharges stable steam directly to your existing steam header. Whether you need low or high steam pressure, Heatcube follows your load dynamically, replacing fossil boilers with zero operational friction.

Drivers for profitable decarbonization with Heatcube

Guaranteed savings

Heatcube supplies low-cost clean industrial steam.

On-demand heat

Absorbs surplus electricity and delivers heat exactly when you need it, 24/7.

Heat without CO2 

Reduce CO2 emissions up to 15,000 tons annually.

Heatcube in action: Replacing gas at scale

In Hungary, KALL Ingredients utilizes Heatcube to power critical unit operations. Replacing natural gas, the system delivers reliable baseload steam for continuous separation and drying processes, comparable to key stages in chemical manufacturing.

By switching to thermal storage, KALL secures 24/7 operational stability and cuts 8,000 tons of CO2 annually under a 15-year Heat-as-a-Service agreement.

FAQs

Answers to the most common customer questions about Heatcube.

Heatcube is designed with a steam temperature range from 135°C to 400°C and can generate up to 20MW of discharge capacity. The saturated steam temperature is between 135°C and 212°C, with a steam pressure between 8 and 20 bar(a). To achieve 400°C with a pressure 3 - 40 bar(a) (superheated steam) a superheater can be added to Heatcube steam generator.

Based on one cycle per day, the round trip efficiency from electricity to steam is minimum 93%.

Heatcube is equipped with a 20 MW steam generation system. The temperature and pressure do depend on the feed water supply and energy storage volume, but our standard configuration (64 MWh storage) delivers more than 12 hours of 7.5 tons per hour at 16 bar(a), with a feedwater temperature of 100°C (equals 5 MWh for 12 hours).

Heatcube is supplied with a Battery Management System (BMS), which can be connected with the local Energy Management System (EMS) using a standard industry interface. The storage tanks do not require any preventive or periodic maintenance. The auxiliary systems (pumps, valves, etc) require minimal ongoing maintenance and training will be provided.

For an industrial facility with steam demand covered by an electric boiler, the energy cost is directly related to the average and/or peak power prices in the region it is located. With Heatcube, we can offer significant energy savings by load-shifting the electricity demand from high-priced to low-priced hours in the power market.

The increasing share of intermittent renewable power production together with decommissioning of fossil-based power generation creates more price volatility in the power markets. In the hours with high wind and solar power output and low demand, the power prices become very low, while in hours with less wind and solar, the power prices are consequently very high. With Heatcube, we are utilizing the increasing price volatility in the power markets to store energy in hours with high renewable production and low prices. When charging Heatcube with cheap electricity from excess renewable power production, we can deliver renewable heat whenever needed at a very low cost. At the same time, we are replacing fossil fuels with renewable electricity as the energy source for heat production, and so removing close to all carbon emissions associated with the industrial heat demand.
