ReMeF-tuning

AI Quick Summary

ReMeF-tuning: Increased reactivity of aluminium grains for the use as ReMeF - Renewable Metal Fuel that can be used to cover winter peak loads of electricity and heat based on renewable energy stored in the aluminium. Renewable Metal Fuels offer new possibilities for the long-term storage of energy with energy densities that are volumetrically twice as high as those of heating oil and ten time higher than liquid hydrogen. For example, a sensational 23.4 MWh of energy can be obtained from an aluminium cube with 1 m side length. This energy can be used in winter to cover the electricity and heat requirements of buildings or industrial processes. For further information of this technology please consult https://doi.org/10.1016/j.ecmx.2019.100017 or https://www.reveal-storage.eu. One of the most promising materials for a Renewable Metal Fuel is aluminium. Due to its low cost and high abundance in the earth's crust, it can be expected that carbon emission free aluminium produced from renewable energies will become a global commodity with largetrade volume in the near future. Previous attempts to use aluminium as a fuel for combustion or for aluminium-water reactions were based on fine aluminium powder. This brings along safety issues and extra cost for safety measures since fine metal powders may react explosively with oxygen. We areusing larger granules or grains that are safe to handle, which comes along with less surface area per weight and thus slower reactivity. In this project we want to increase reactivity of aluminium grains in our specific reaction environment by alloying with other elements that enhance reactivity of the exothermic aluminium-water reaction that produces hydrogen and aluminium hydroxide.

One of the most promising materials for a Renewable Metal Fuel is aluminium. Due to its low cost and high abundance in the earth's crust, it can be expected that carbon emission free aluminium produced from renewable energies will become a global commodity with large

trade volume in the near future.

Previous attempts to use aluminium as a fuel for combustion or for aluminium-water reactions were based on fine aluminium powder. This brings along safety issues and extra cost for safety measures since fine metal powders may react explosively with oxygen. We are

using larger granules or grains that are safe to handle, which comes along with less surface area per weight and thus slower reactivity.

In this project we want to increase reactivity of aluminium grains in our specific reaction environment by alloying with other elements that enhance reactivity of the exothermic aluminium-water reaction that produces hydrogen and aluminium hydroxide.
