ETTEPLAN OYJ, Press release, March 3, 2025 at 11.00 a.m. (EET)
Etteplan and TheStorage collaborate on an innovative sand battery technology project
The technology service company Etteplan is carrying out subcontracted plant design work for TheStorage's first renewable energy Proof of Concept heat storage project, which aims to support the electrification of heat production in the industry. The collaboration is part of TheStorage's product development program, which seeks to offer a future cost-effective, grid-scale energy storage solution that is capable of discharging heat, steam, or CHP (Combined Heat & Power) using sand battery technology.
TheStorage specializes in developing and manufacturing energy storage systems that enable the flexible electrification of industrial heat production. These systems allow industrial processes requiring high temperatures to transition to fossil-free operations by utilizing stored, affordable, and emission-free renewable energy, resulting in significant cost savings.
The Proof of Concept system is a mobile test device that will be evaluated in various applications with multiple customers. Depending on the customer's needs, the stored heat can be discharged as hot water, steam, hot oil, or air.
"We are honored to support our customer TheStorage in their new and innovative sand battery technology project. With our expertise in technical plant operations, we can contribute to our customer's success in their first projects. Our extensive network enables collaboration among the most competent professionals in various fields, and our close cooperation will certainly prove beneficial to our customer in this project. Our goal is, of course, to continue the collaboration with TheStorage in the future," says Petri Järvenpää, Area Manager of Plant Engineering at Etteplan Tampere.
"We chose Etteplan as our design partner because of their versatile and extensive expertise. Etteplan had the know-how for every design area we needed. Etteplan efficiently addressed our design needs and was not deterred by the tight schedule of our project. Our goal is to successfully complete the project and continue our excellent cooperation in the future," says Timo Siukkola, CEO of TheStorage.
Etteplan's design and procurement services are currently in full swing, and the construction of the Proof of Concept system has already begun. The goal is for the mobile test device to be in the testing and commissioning phase by May 2025.
