MIT Engineers Innovate Zero-Emissions Hydrogen Fuel from Aluminum and Seawater

Using recycled soda cans and caffeine, researchers develop a sustainable method to produce hydrogen gas for marine and underwater vehicles.

Hydrogen gas is generated by mixing pretreated aluminum pellets with seawater, accelerating with caffeine.
The reaction avoids the need to carry hydrogen tanks, using aluminum as the fuel source instead.
A rare-metal alloy helps to maintain aluminum's reactivity by removing oxide layers.
The process is sustainable, allowing the recovery and reuse of the alloy from seawater.
Potential applications include powering marine vessels, underwater vehicles, and potentially other transportation forms.
