Are you thinking of aluminum recycling, which is much easier than aluminum smelting, which is not an incredibly efficient process? I think recycling aluminum requires 5% of the energy that smelting it requires.
- neltnerb 5y agoIt is possible, I didn't look up numbers. Still, it's hard to imagine inserting a step being a practical solution. I expect a reasonable high density low pressure hydrogen storage solution to happen sooner at any scale, a solid fuel isn't particularly practical either except in a one-use battery.

- Retric 5y agoThat’s a misunderstanding. Aluminium smelting is the process of extracting pure Aluminium from its oxide. https://en.wikipedia.org/wiki/Aluminium_smelting https://en.wikipedia.org/wiki/Aluminium_smelting Recycling generally avoids smelting aluminum because Aluminum in say cans only has an atomic scale coating of Aluminum oxide around pure Aluminium.
