Hydrogen is a good tool for thermobaric explosives. The hydrogen-oxygen mixture is a very high-explosive material. The problem with hydrogen is that the gas is so lightweight. The wind is always the problem with fuel-air explosives, FAE because it blows the explosive fuel mixture away. In some scenarios, terrorists use hydrogen thermobaric explosives to destroy targets. In those scenarios, the electrolytic system creates a hydrogen cloud. And then that hydrogen will fill the space and the system detonates it. 

The problem is how to make the hydrogen cloud. And keep it so dense. That an explosion can happen. In some scenarios, the system releases hydrogen first into the balloon, and then the ignition system makes a hole in that hydrogen balloon and detonates. 

The Chinese researchers used a solid-state compuóund called magnesium hydride to release very much hydrogen. The 2kg system creates a fireball with a temperature over 1000C. And, when we think about the other ways to use the hydrogen-air mixture as an explosive there is always the possibility of injecting oxygen and hydrogen into the tank. There the detonator can detonate that gas mixture. 

There are many ways to make the hydrogen-oxygen mixture. Ammunition, that uses hydrogen can be two-chamber ammunition, normally used as chemical weapon carriers. The hydrogen creator, like sodium or some other alkali metal that creates hydrogen when it touches water, is in another chamber. And there is water in another tank. When water touches alcal metal, hydrogen is produced. And then. The ignition system ignites the hydrogen in that chamber. 

The system can use very small alkali metal bites that maximize the surface which participates in the hydrogen creation reaction. The problem is that this reaction should create hydrogen very fast so that the hydrogen creator can create enough hydrogen for fast flying. 

Another way is to use hydrogen and oxygen that are stored in the ammunition. When those gasses make a mixture in the grenade or bomb that can be used as normal explosives. Chinese solved the problem by using a metal alloy called magnesium hydride. That metal alloy delivers hydrogen very fast. These kinds of weapons are very dangerous because they are very easy to make.
