Firebricks offer low-cost storage for carbon-free energy

An ancient technology could be used to level electricity prices for renewables.

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.

One proposed application of the firebrick-based thermal storage system is depicted in this hypothetical configuration, where it is coupled to a nuclear power plant to provide easily dispatchable power.
