When mixed with an oxidizer (e.g., ammonium perchlorate) in solid rocket boosters, it burns hotter and with higher specific impulse (thrust efficiency) than traditional aluminium powder. The main issue preventing mass adoption is its lack of long\u2011term shelf stability.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4.2 Hydrogen Storage Vector (Fuel Cells)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Hydrogen\u2011powered cars struggle because storing enough hydrogen requires high\u2011pressure tanks.

LiAlH\u2084 is an ionic salt that is easier to handle and more common in synthesis. Pure AlH\u2083 (alane) is a polymer lacking lithium, making it significantly harder to synthesize and store safely.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q: If it holds so much hydrogen, why aren\u2019t our cars powered by this powder yet?<\/strong><br>A: Two major problems: (1) Alane degrades on the shelf over months, releasing hydrogen prematurely. (2) Regenerating AlH\u2083 from the leftover aluminum dust requires extremely high hydrogen pressure (nearly 100,000 atmospheres), making the recycling loop currently impractical.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q: Does it actually explode when wet?<\/strong><br>A: It does not detonate like TNT. Instead, water causes violent boiling, releasing large volumes of hydrogen gas.
