that could compactly and safely store energy , laying the foundation for a sustainable future .
Iron Power , the brainchild of this ESA collaboration , introduced a novel approach to energy storage . The process begins with the controlled combustion of iron powder , yielding heat that can be utilized for various applications . What sets Iron Power apart is its regenerative capability — using hydrogen derived from abundant solar and wind energy sources , the iron oxide produced during combustion is seamlessly converted back to iron powder .
Advantages of Iron Power The significance of this technology lies not only in its carbon-free combustion but also in its potential to offer a low-cost , safe , and environmentally friendly solution for storing substantial amounts of energy . Iron Power emerges as a beacon in the energy transition , particularly in industries reliant on intensive heat processes .
The combustion of iron powder stands out due to its low environmental impact , boasting minimal NOx and particle emissions . At approximately 2000 ° C , the combustion temperature aligns with that of fossil fuels , making it relatively easy to integrate into existing infrastructure .
Furthermore , at 25 MJ / L the volumetric energy density of iron powder surpasses that of conventional energy carriers like ammonia and compressed hydrogen , presenting a compelling case for its widespread adoption . This unique combination of clean combustion , high energy density , and cost competitiveness positions Iron Power as a transformative force in the sustainable energy landscape .
Potential of Iron Power Approximately 65 % of industrial energy consumption is allocated to heating processes ,
