Heatcube

Kyoto Heatcube is a breakthrough and highly innovative solution to effectively electrify industrial process heat by replacing today’s natural gas boilers. Utilizing Heatcube instead leads to significant CO2 reductions, ranging from 1,000 to 14,000 tons annually per Heatcube, depending on its size and configuration. With substantial CO2 reductions, reasonable initial investment, and a 25-year lifespan, Heatcube offers an immediately available, cost-effective, flexible, safe, and sustainable solution. Our solution can be replicated wherever process heat in the temperature range supplied by Heatcube is needed. The installation of Heatcube on client sites is a plug-and-play concept, facilitating the replacement of old carbon-intensive technology.

Heatcube allows industrial heat to be produced independently from when power is supplied. By allowing for energy to be stored in the salt medium, Heatcube can be charged when electricity is least expensive. This is called load shifting and promotes the use of abundant and affordable renewable energy for clean and stable process heat. Heatcube can be tailored to optimize performance based on the required heat demand by utilizing three core components for charging, storing, and discharging. By combining proven technology with state-of-the-art design, our current Heatcube can provide a constant steam output between 170° C and 400° C. Kyoto’s modular approach allows solutions to be dimensioned to each industrial customer based on charging capacity, storage capacity, and heat generation, while still being a plug-and-play solution.   

Heatcube can be fully charged in hours and, at the same time, supply heat continuously. A distinctive feature is that it can charge and discharge simultaneously, allowing the utilization of renewable energy whenever it is available without interrupting the heat supply. The short ramp-up time enables users to access the balancing (frequency reserve) markets, offering an additional source of income for its operator and a balancing asset for the grid for the TSO/DSO (grid operators – Transmission System Operator/Distribution System Operator).
