Long-term, heat-based energy storage in aluminum
From pv magazine Germany
The “Reveal” research project began in July, with a number of big goals. They are focusing on the further development of advanced technologies that can produce aluminum from alumina without carbon dioxide emissions. And they are working on technologies to use the metal as a medium for long-term storage of electricity as heat, which can be extracted and used to heat homes in buildings during winter months.
The EU Horizon Europe funding program and the Swiss State Secretariat for Education, Research and Innovation (SERI) are supporting the project with €3.6 million ($3.7 million). The project will run until 2026.
Reveal’s main focus is the development of technology that can store energy from PV, wind and hydropower for months or even years at low cost. Nine partners from seven different European countries are participating in the project. It builds on ideas and preliminary projects from the SPF Institute for Solar Technology at the OST. The concept is fundamentally different from traditional methods of energy storage such as batteries, hydrogen or synthetic fuels, and uses aluminum metal as a medium for energy storage.
Researchers in Iceland have already shownthat electrical energy from renewable sources can be chemically stored in aluminum without emitting greenhouse gases. The OST team was able to back this up by showing that aluminum can be used to generate heat and electrical energy with great efficiency.
Initial model calculations also showed that storing energy in this way can be significantly cheaper than, for example, with power-to-gas or synthetic fuels. The discharge of the energy stored in the aluminum leads to reaction products. These can be converted to aluminum with new energy. But ultimately, the costs and environmental impact will be decisive for the success and sustainability of the concept, according to the Eastern Swiss University of Applied Sciences.

[…] The basis of a new research project – called “Revell” – is based on taking advantage of renewable energy sources to generate electricity supplies that are stored in aluminum metal, and can be used at a later time, according to what was published by PV Magazines (PV magazine). […]
Pretty useless as presented. Like the last guy, just what are u talking about??? A giant block of solid aluminimium buried in the ground that you heat up, melted aluminium stored in a thermal bottle at 5000 degrees C???
You gave us a worthless and meaningless headline with no info ??? : ((((

I’m intrigued, but baffled. Break it down for me? What exactly is the mechanism? How does it work? Give some practical examples of how it’s applied. This article is bare bones, IMHO. Maybe I’m just not scientific enough.
