By proving a fast and reliable charging response, Kyoto's Heatcube at
The power market test confirmed Heatcube's operational performance, successfully achieving a smooth and dependable ramp-up of the heater from 0 MW to 5 MW in 90 seconds, well within the requirements for the balancing market participation in question.
Heatcube consistently operated well and above its designated design parameters, demonstrating its stability and reliability. Please refer to the graph below for a visual representation of the test results, ramping up to, holding and down from 5 000 kWe (5 MW) for approximately 10 minutes during the 15 min test.

The test was executed by giving a start signal for activation, whereafter the battery management system automatically aligned the valves for charging. The pump was then activated, and when steady flow was achieved, the heater swiftly ramped up to 5MW load within seconds.
The complete activation sequence happened within 90 seconds. The heater stayed at a stable level of 5MW for approximately 10 minutes, whereafter the load of the heater was ramped down to 0 MW, the pump was turned off and the valves automatically closed.
The deactivation also happened within 90 seconds, and the system was seamlessly brought to standby mode. Throughout the test, the outlet temperature of the molten salt from the electrical heater smoothly increased from 220°C to a maximum of 415°C.
"We are proud of our offering of flexibility services to the electricity market, which will be a critical component of the energy market going forward, when intermittent renewable energy will dominate the supply side of the global energy system. With Heatcube, Kyoto can provide a balancing asset for the grid operators while at the same time providing heat at the lowest cost possible for our customers," says Bjarke Buchbjerg, CTO of
By proving this first-of-its-kind capability towards the electricity market, Kyoto presents a truly unparalleled and validated technology. This innovation can simultaneously decarbonize industrial process heat, tap into the most cost-effective or even cost-free electricity sources, and sometimes even generate revenue by providing reliable, on-demand heat for industrial decarbonization.
"We are excited by the prospect of integrating Heatcube into the power market. The successful test has unequivocally demonstrated the technical readiness and capabilities of this unique technology," says Søren Gais Kjeldsen, CEO of Aalborg Forsyning.

"This achievement displays the effectiveness of our thermal energy storage technology and paves the way for a future where industrial process heat is sourced from clean, renewable electricity, enabling the industry to finally decarbonize while optimizing its operational expenses. We are proud to lead the change towards a greener future," says

About
Heat accounts for two thirds of industrial energy consumption. Traditionally, nearly all of it is based on fossil fuels. Kyoto Group's Heatcube, a thermal energy storage (TES) solution, provides a sustainable and cost-effective alternative by capturing and storing abundant but variable energy from sources such as solar and wind. Founded in 2016,
