A brewery in the Netherlands is making environmental history by using a cycle of renewable iron as fuel for its furnace. Here''s how it works.
Energy from sun or wind is weather-dependent and lacks an efficient way to store and transport it. Scientists from the Max-Planck-Institut für Eisenforschung and TU Eindhoven are investigating
Iron Fuel solves this problem by storing renewable energy in iron powder, enabling energy release when and where needed in a safe and CO2-free manner. The combustion of iron powder produces energy, with the only by-product being iron oxide, or rust.
During the iron combustion, thermal energy is released as heat. The combusted products, the iron oxide particles, are captured and cyclically reduced back into iron powder in a process that is powered by renewable energy. Each combustion step, followed by a reduction, constitutes one cycle in the process.
This publication cements the applicability of iron particles as a metal fuel for energy storage and release in retrofitted powerplants. For the envisioned cycle process, high fuel usage efficiencies while retaining a similar morphology and particle size are desired.
Iron Fuel can solve industry's problem by storing renewable energy in iron powder. By burning this iron powder, energy can be released when we need it and where we need it in a safe and CO2 free manner. The burned product, rust, can be regenerated back into iron fuel using renewable energy.
Iron Fuel serves as a transformative energy carrier, addressing the challenges faced by power plants and heat demanding industries responsible for 40% of global CO2 emissions. Sources like the sun and wind generate renewable electricity, but their intermittent nature poses challenges for consistent energy supply.
When burned in laminar or turbulent flames formed from the suspension powders or sprays of micron-sized particles, iron has combustion characteristics close to those of hydrocarbon fuels in terms of heat release, flame temperature and burning velocity , , .
