Cut emissions and costs with thermal storage


Food and beverage producers face an urgent challenge: transitioning to sustainable energy.

Food and beverage producers face mounting pressure to adopt clean energy. Rising energy costs squeeze already tight margins, while looming regulatory deadlines leave little time to act. At the same time, sustainability demands from customers, investors, and ESG frameworks are growing louder. Balancing these pressures with practical solutions is no easy task, and delays only drive up costs and risk falling behind competitors.

That’s where Kyoto Group’s Heatcube steps in. Our thermal battery technology replaces fossil fuel boilers to deliver clean process heat, simplifying the transition to clean energy and cutting scope 1 and scope 2 emissions. Whether you invest in your own Heatcube or opt for Heat-as-a-Service (HaaS)—delivering clean steam on demand with no upfront costs—we have a solution tailored to your business and budget.

Partnering with Kyoto Group turns sustainability into a business asset.

Hit ESG targets

The EU food & beverage sector accounts for 30% of greenhouse gas emissions. Thermal storage integrates clean process heat into your processes, cutting CO₂ emissions by 1,000 to 14,000 tons annually and helping you achieve sustainability goals with ease.

Control energy costs

By leveraging cheaper, off-peak electricity, thermal storage reduces dependence on volatile gas markets and shields your operations from rising carbon taxes—all while ensuring a continuous heat supply for your production.

Get paid to play

Heatcube is a balancing asset for the electrical grid, enabling you to earn additional revenue by providing load balancing or demand response services to grid operators—backed by expert insights and guidance from the Kyoto Group team.

Heatcube: Proven and working

Heatcube is a thermal battery delivering high-temperature clean process heat for industrial processes, replacing fossil fuels with renewable energy. The tech is already operational, providing reliable heat in real-world settings. Designed to integrate seamlessly into existing systems, it offers a tested, cost-effective solution for industries looking to cut emissions and stabilize energy costs.

Here’s how Heatcube works

Heatcube stores energy from renewable sources like wind and solar during off-peak, low-cost hours. Molten salt is heated by multiple renewable sources to over 415°C to release high-temperature heat (steam) on demand, ensuring a consistent and sustainable energy supply.

 

KALL Ingredients: Thermal storage at work

In Hungary, KALL Ingredients is decarbonizing and advancing starch production with Kyoto Group’s Heatcube. This project, now nearing completion, is set to replace fossil fuels with clean, renewable heat—cutting emissions by up to 8,000 tons of CO₂ annually, stabilizing energy costs, acting as a balancing asset for the electrical grid and proving that industrial decarbonization is not just a concept, but a tangible reality.

FAQs

Answers to the most common customer questions about Heatcube.

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.

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.
