Overview

  • Firebricks can store heat from renewable sources, reducing reliance on fossil fuels for industrial processes.
  • Using firebricks could save $1.27 trillion in capital costs compared to electric heat solutions by 2050.
  • The technology can decrease the need for battery storage by 14.5% and hydrogen production by 27.3%.
  • Firebricks are one-tenth the cost of batteries and made from simple materials like alumina and magnesia.
  • Researchers believe firebricks will accelerate the shift to net zero emissions and improve public health.
