Not like this, no. Please consider reading articles further before making such statements. I cannot speak for the veracity of the experimental claims, but it isn't a simple clickbait about hydrogen gas - it's a breakthrough in chemical engineering.

In a controlled field test, as reported by the South China Morning Post, the 2kg device produced a white-hot inferno exceeding 1,000C for over two seconds—15 times longer than equivalent TNT blasts

This is similar to napalm in temperature, but rather than spraying hot burning goo, you're effectively igniting the air itself. For two entire seconds, which is a lot longer than it sounds when discussing a literal ball of fire.

When triggered by conventional explosives, the material fractures into micron-scale particles, releasing hydrogen gas that mixes with air and ignites. This creates a self-sustaining combustion loop: the heat from the initial explosion propagates further decomposition of magnesium hydride, releasing more hydrogen and extending the fireball’s duration.

This isn't an article about a hydrogen gas experiment like in school. It's about them finding a way to mass produce the amount of magnesium hydride required for such a potentially devastating firebomb. It's more hydrogen-dense (and therefore more energy dense) than pure liquid hydrogen, which is used as rocket fuel.

For comparison, one cubic meter can contain 45 kg of hydrogen pressurized at 700 atm, 70 kg of liquid hydrogen, or up to 106 kg of hydrogen bound in magnesium hydride

Really good point

"WOW Local Man STRIKES a MATCH, which reached TemperaTures of MORE THAN 500°C !! 🤯"

That is really how headlines like that sound. Stop writing crap like that. Who becomes a journalist just to write clickbait, seriously?

Sorry for the hate OP, but please post a headline which is less clickbaity. It does not paint the article in a good light, no matter how interesting the subject might be.
