Daniel Stack won the DOE Energy Storage Innovations Prize ( https://www.energy.gov/oe/articles/doe-announces-energy-storage-innovations-prize-winners ) based on his development of electrically conductive firebrick. The prize and his startup company Electrified Thermal Solutions ( https://www.electrifiedthermal.com/ ) are based on his NSE PhD thesis ( https://dspace.mit.edu/bitstream/handle/1721.1/130800/1252204287-MIT.pdf... ) that was completed in 2021. Electrically conductive firebrick provides a low-cost way to convert electricity into high-temperature heat matching the temperatures of a natural gas flame. The conductive firebrick allows heat storage at very high temperatures in firebrick recuperators for industry, gas turbines and Nuclear Air-Brayton Combined cycles with power peaking capabilities.
