ReMeF is an international scientific symposium on the topic Renewable Metal Fuel organized for the first time in Switzerland by the University of Applied Sciences OST. Distinguished scientists and experts will share their ground-breaking insights regarding renewable metal fuels. ReMeF symposium serves as a platform for the exchange of novel knowledge, fostering discussions that may lead to game-changing solutions.

One of the main challenges preventing the transition to a renewable-energy landscape and achieve the Energy Strategy 2050 is the energy storage. The seasonal or long-term energy storage will become a central issue for our future energy systems. If we can store excess electricity in peak production seasons until the season of peak demand, we will be able to significantly increase our energy independence and increase the share of renewable energy in our consumption mix.

ReMeF are Renewable Metal Fuels – a game-changing solution for providing buildings and industry all year with clean energy and avoiding the use of fossil fuels, thus minimizing the CO2 emissions. Various metals such as aluminium and iron stand out as promising candidates for long-term storage and transport of large amounts of renewable energy over considerable distances. These metals exhibit the ability to undergo reactions, either with oxygen to release heat or with water to generate hydrogen. The resulting by-products, oxidized metals, can be efficiently recycled, and through the input of renewable energy sources, reduced back to their metallic form. This innovative approach addresses the need for reliable, scalable, and sustainable methods for storing and transporting renewable energy.

For storing large amounts of energy over longer periods, there are significant advantages if these metals are not used in rechargeable batteries. Instead, the oxidized metal is reduced in a Power-to-X process in a first step (storage charging), and the energy is recovered later at any place and time via the oxidation of the metal (storage discharging).

Renewable metal fuels can achieve significantly higher energy densities at lower costs and environmental impacts compared to conventional batteries or other Power-to-X processes. Metal fuels can be recycled from the metal oxide products an infinite number of times while avoiding loss of material. Metal fuels offer the safe and efficient solutions and can be stored for longer periods of time and transported over long distances. They are available in large quantities and can be produced carbon-free.

Distinguished scientists and experts at the forefront of this emerging field will converge to share their ground-breaking insights. The ReMeF symposium serves as a platform for the exchange of novel knowledge, fostering discussions that may lead to game-changing solutions. Renewable metal fuels are extremely promising and will attract a significant attention as humanity moves forward on its quest to fight anthropogenic climate change.
