CIRCL - Closing the iron reduction-combustion loop

Iron powder is a new promising high-energy density, CO2-free energy carrier. When iron particles are combusted, heat and power are generated.

The combustion products, iron oxides particles, are recovered and converted back into iron using green hydrogen. Contrary to other storage and conversion concepts, metal powders are simple to store at large scale, safe to handle and transportable.

CIRCL focuses on dedicated experiments and advanced numerical simulations of the regeneration of the iron oxides back to iron in a fluidized bed using green hydrogen. This will enable future scale-up to industrial size applications of the metal energy storage and conversion system.
