China has successfully developed and tested a powerful non-nuclear hydrogen explosive with significant military potential for precision thermal strikes.

This device, weighing about 2 kilograms, was detonated in a controlled field test by the China State Shipbuilding Corporation’s (CSSC) 705 Research Institute, known for its expertise in underwater weapon systems.

Unlike traditional nuclear hydrogen bombs, this weapon uses a magnesium-based solid-state hydrogen storage material called magnesium hydride, which can store more hydrogen in a compact and stable form compared to pressurised tanks.

Upon activation by conventional explosives, the magnesium hydride undergoes rapid thermal decomposition, releasing hydrogen gas that ignites and produces a sustained, intense fireball exceeding 1,000 degrees Celsius.

This fireball lasts for more than two seconds—about 15 times longer than the flash produced by an equivalent TNT explosion—and generates a white-hot flame capable of melting aluminium alloys and causing extensive thermal damage. The explosion creates a chain reaction where the initial blast breaks the magnesium hydride into fragments, releasing more hydrogen and sustaining combustion in a self-feeding loop.

A key advantage of this hydrogen bomb is its precise controllability over blast intensity, allowing it to uniformly destroy targets across vast areas or concentrate thermal energy on high-value points for targeted strikes.

This capability represents a significant advancement in weapon technology, offering powerful thermal effects without the radioactive fallout associated with nuclear weapons. The device's blast pressure is roughly 40% of a comparable TNT explosion, but the heat released far exceeds TNT's thermal output, making it effective for precision thermal warfare.

China has also invested in large-scale production of magnesium hydride, establishing a factory in Shaanxi capable of producing 150 tons annually using a safer and more cost-effective "one-pot synthesis" method. This industrial capacity supports both military applications and potential civilian uses, such as powering submarines, fuel cells, and long-endurance drones.

This development marks China's entry into an elite group of nations possessing advanced hydrogen bomb technology that is non-nuclear yet capable of delivering devastating thermal strikes. The weapon's clean-energy profile and controlled blast characteristics suggest a shift in warfare technology towards precision, high-energy thermal weapons that avoid the long-term environmental and health consequences of nuclear arms.
