Iron powder as a circular fuel. How does it work?

Iron powder can be used as a safe, compact, cheap and CO2-free circular fuel. Simply put: a dust cloud of iron powder mixed with air is ignited in burners, causing the iron particles to burn quickly (rust in a fraction of a second). The rust particles are collected via a large vacuum cleaner and the remaining hot gas can be used for the use of sustainable (high-temperature) heat for, among other things, industry, built-up areas (district heating) or transport (ships). At places and times where a lot of sustainable energy is available, the collected rust powder is converted back into iron powder, so that the circle is closed and the iron powder can be reused. The iron powder therefore functions as a huge 'battery' for the storage of sustainable energy.
