In the fight against climate change, Electrified Thermal Solutions' electrically conductive firebrick, developed at MIT, is paving the way for a cleaner industrial future. Known as "e-Bricks," these bricks can reach temperatures above 3,000°F, challenging the industry's reliance on fossil fuels for heating, as per a Massachusetts Institute of Technology report.
Historically, sectors such as cement, steel, and paper production have relied on combustion for their heating needs, releasing copious amounts of carbon into the atmosphere. Daniel Stack, an MIT graduate and a pioneer in this realm, has focused his efforts on revolutionizing this process by developing thermal batteries that provide intense heat from electricity. These thermal batteries, potentially powered by renewable energy sources, present a significant leap towards decarbonizing heavy industry. "We have a global perspective at Electrified Thermal, but in the U.S. over the last five years, we've seen an incredible opportunity emerge in energy prices that favors flexible offtake of electricity," Stack revealed in a statement obtained by MIT News.
The genesis of this innovation can be traced back to Stack's research at MIT, where his original plans to advance nuclear reactor technology took a turn towards the heating properties of bricks, under the guidance of his advisor Charles Forsberg. Through a reimagined approach to the humble firebrick, commonly used for insulation and heat storage, Electrified Thermal's version adds electrical conductivity into the mix. This allows the bricks to direct heat themselves, efficiently storing and releasing thermal energy.
With the vision of scaling this technology for widespread industrial application, Electrified Thermal has been in discussions with companies across a variety of fields, from glass production to food and beverage. Their solution not only promises to fulfill temperature requirements of these industries but also to do so in an affordable and eco-friendly manner. Despite the seeming simplicity of their design, these e-Bricks tackle a complex global challenge. "The industrial heating challenge affects everyone under the sun," Stack said, according to an interview with MIT News, indicating the sweeping potential of this technology for zero-carbon energy transition.
Electrified Thermal is on track to complete a commercially viable megawatt-scale system in the next seven months. This system will not only prove the technology but also highlight the potential of moving away from fossil fuels for industrial heating. The Department of Energy has invested $40 million in the company. "Next year will be a huge proof point to the industry," Stack told MIT News.
