Firebricks offer low-cost storage for carbon-free energy

Boston MA (SPX) Sep 15, 2017

Firebricks, designed to withstand high heat, have been part of our technological arsenal for at least three millennia, since the era of the Hittites. Now, a proposal from MIT researchers shows this ancient invention could play a key role in enabling the world to switch away from fossil fuels and rely instead on carbon-free energy sources.

The researchers’ idea is to make use of excess elec
