Our mission is to enable access to clean and renewable energy for anyone, at any time. We do this by creating an ecosystem for iron fuels as circular energy carriers. In this way, we reduce the emissions originating from heavy industries that currently lack viable solutions.
Iron Combustion
Another technique involves a circular principle in which iron powder is used as a medium for energy storage, also called iron fuel. Iron fuel can be burned to form iron oxide, better known as rust. In this process, a large amount of thermal energy is released that can be used in industrial processes. The resulting iron oxide is a solid material, so it can be captured after the combustion process. It is then reused by regenerating it with green hydrogen into new iron fuel. This way, iron fuel offers a revolutionary method to store energy in a circular and carbon-free fashion.
A detrimental side of iron fuel that it has a relatively low specific energy density, which is the amount of energy per kilogram of iron. Therefore, it cannot be used in applications in which weight is of importance such as cars, trucks and planes. Also, it can only be transported in an economic manner by ship or train. However, most of the heavy industries are located on railways or waterways. Therefore, iron fuel is applicable to those industries.
After multiple years of development by SOLID and its partners, the iron combustion technology reached certain TRL levels that are outside the scope of SOLID. Hence, the development of this technology has been passed on to the industry, especially companies like RIFT and IRON+.
