Norway-based thermal energy storage company Kyoto Group has signed a letter of intent (LOI) to deploy an 88MWh system in Spain in the second half of 2023.
The LOI has been signed with an unnamed company described in a press release as “one of the largest owners of cogeneration facilities in Spain”. The agreement, if followed through, will see Kyoto Group deploy an 88MWh energy storage system at one of the company’s facilities in Spain, providing emissions-free heat production 24/7.
Major owners of combined cycle gas turbine plants in the country include Naturgy, AES, Endesa and Iberdrola.
“With the Heatcube system, we would like to operate our plant in a more optimal way than we have been doing up to now, allowing the generation of additional renewable steam for our industrial process. Additionally, we want to continue with our strategy of reducing the carbon footprint in our facilities,” said the COO of Kyoto’s unnamed partner company.
Although the link between the two developments is not clear, Kyoto bought a Spain-based firm with a number of intellectual property rights related to the development of thermal energy storage, which it then renamed Kyoto Technology Spain, in March. The acquisition of Mercury Energy was covered at the time by Energy-Storage.news.
Kyoto’s Heatcube product is a modular storage solution for thermal energy, which works by heating salt to – currently – 415 degrees celsius, which is then used to produce stream for industrial production processes. The company says its ternary salt can store thermal energy up to 525 degrees celsius.
The Heatcube can be configured with storage capacities from 16-96 MWh, or more, with a discharge for each Heatcube of up to 5MW.
In August, it signed an LOI with corrugated cardboard manufacturer Glomma Papp to deploy a system for a commissioning as early as summer 2023.
