Toshiba and Marubeni have revealed plans to build commercial projects based on thermal storage technology using rocks. They have set up a demonstrator with 100 kWh of storage capacity and a relatively high heat storage density. November 23, 2022 Emiliano Bellini Japan’s Toshiba and Marubeni, along with Japanese utility Chubu Electric Power, have deployed a pilot rock-based storage facility at Toshiba’s facility in Yokohama, Japan.The pilot system has a storage capacity of 100 kWh and can use storage materials such as crushed stone, bricks, molten salt, concrete, and ceramics. Toshiba said the pilot facility has a relatively high heat storage density. It claims it can store heat at temperatures above 700 C, with a relatively small heat storage tank.The next step in the project is to build a larger facility with a capacity of 500 kWh. The group aims to eventually launch commercial…
