German paper and packaging manufacturer Klingele Paper & Packaging Group has signed a term sheet with Kyoto for the installation of its molten salt thermal energy storage solution, Heatcube.

The initiative is part of Klingele’s commitment to reduce its carbon dioxide (CO₂) emissions by 2030.

Kyoto will install Heatcube at Klingele’s corrugated board plant in Werne, Germany, where the company aims to reduce CO₂ emissions by 55%.

Klingele will achieve this target by leveraging off-grid wind and solar energy and replacing its existing gas boilers with steam production.

Kyoto’s Heatcube will capture electricity when available and supply steam when required.

The Heatcube system has a 10MW charge capacity, 48MWh storage capacity, and 7MW discharge capacity.

It will be capable of delivering a capacity of more than 15GWh a year.

The new system is expected to reduce more than 3,400 tons of CO₂ annually, aiding Klingele’s target of complete decarbonisation.

The commercial contract for the Heatcube installation is anticipated to be finalised by April 2024, with the installation process expected to take approximately 12 months.

Klingele managing partner Jan Klingele said: “As a pioneer in sustainability, we have been focusing on environmentally friendly and resource-efficient processes in the production of our corrugated board paper and packaging for years.

“At the same time, we are constantly investing in technologies and innovations to make our energy generation and energy consumption even more environmentally friendly. We are therefore pleased about the joint project with Kyoto Group, as a further milestone in our renewable energy strategy.”
