Aluminum-powered climate change resiliency: From …
Bulk aluminum can be made water-reactive via a minimal surface treatment of gallium and indium, which works to passivate the oxide layer that would otherwise inhibit the reaction. With this oxide layer disrupted, the underlying bulk aluminum is able to react exothermically with water to produce hydrogen gas and aluminum oxyhydroxide (AlO(OH)) at high levels of reaction completion (>95%).
