In an effort to clean up the industrial sector, some startups are changing manufacturing processes for specific materials. Some are even changing the materials themselves. Daniel Stack SM '17, PhD '21 is trying to address industrial emissions across the board by replacing the heat source. Since coming to MIT in 2014, Stack has worked to develop thermal batteries that use electricity to heat up a conductive version of ceramic firebricks, which have been used as heat stores and insulators for centuries. In 2021, Stack co-founded Electrified Thermal Solutions, which has since demonstrated that its firebricks can store heat efficiently for hours and discharge it by heating air or gas up to 3,272 degrees Fahrenheit ' hot enough to power the most demanding industrial applications. Achieving temperatures north of 3,000 F represents a breakthrough for the electric heating industry, as it enables some of the world's hardest-to-decarbonize sectors to utilize renewable energy for the first...
