Heatcube´s high voltage connection to grid at Nordjylland Power Station successfully commissioned

Heatcube´s high voltage connection to grid at Nordjylland Power Station successfully commissioned

Oslo, Norway 12 July 2023 - Kyoto Group is pleased to announce that the first

ever full-scale Heatcube, at the Nordjylland Power Station in Aalborg, Denmark

("Norbis Park") has now been connected to the grid and the high voltage

connection between the transformer building and the world's largest electrical

heater for molten salt, as a key equipment of Heatcube, has been successfully

commissioned.

The connection and electronical testing of the heater were accompanied by a team

of technicians from Vulcanic, the Spirax Sarco company that has delivered the

electrical heater to Heatcube at Norbis Park and that recently invested in and

signed a long-term Partnership Agreement with Kyoto Group, covering commercial

roll-out and technology development related to the electrical heater for future

generations of Heatcube.

"We are proud of the smooth and successful introduction of the world's largest

electrical heater for molten salt and are looking forward to the large-scale

commercial roll-out of Heatcube as well as the further development of the

technology together with Kyoto Group," says Christopher Molnar, Managing

Director of Vulcanic and incoming board member of Kyoto Group.

Heatcube is now monitored and controlled using the Battery Management System

(BMS) from a remote control room or locally at the panels, by the commissioning

engineers. The BMS enables all equipment and assets for testing and protects

Heatcube using automatic safety measures which are now installed.

"Today marks a momentous milestone in our journey as a leading technology

provider to the net-zero society," says Kyoto's Chief Project Officer Agnieszka

Sledz. "We are about to successfully conclude our groundbreaking project that

not only showcases the capabilities of our technology as well as our

organization but also sets a precedent for thermal energy storage as an enabler

to electrify industrial process heat."

The final step in the hot commissioning process for Heatcube at Norbis Park is

to circulate molten salt through Heatcube to discharge steam from the steam

generator, which is planned for the second half of July.

About Heatcube

Kyoto Heatcube provides thermal energy storage and heat generation in one

product. It supplies industrial customers with the technology needed to lower

both their costs for producing process heat and their CO2 emissions using

intermittent renewable energy sources instead of fossil fuels for heat

production.

Heatcube can be configured with storage capacities from 16 MWh to over 96 MWh,

with a discharge effect for each Heatcube of up to 20 MW. It is an innovative,

low-cost, and modular storage solution for thermal energy that can use multiple

renewable energy sources to heat molten salt to over 415 degrees Celsius. The

high-temperature salt is then used to produce steam for industrial production

processes.

About Kyoto Group

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, Kyoto Group is headquartered in Oslo,

Norway, and has subsidiaries in Spain and Denmark. The Kyoto share is listed on
