Chinese researchers have successfully detonated a new
hydrogen-based explosive
device, signalling a leap in the country's military capabilities. This breakthrough, described as a
non-nuclear hydrogen bomb
, was developed by the
China State Shipbuilding Corporation
(CSSC), with the device tested in a field experiment. Unlike traditional nuclear bombs, it harnesses a magnesium-based solid-state hydrogen storage material that ignites to create a sustained fireball, capable of producing heat 15 times longer than a TNT explosion.
A revolutionary weapon
The device, weighing just 2 kilograms, has a unique explosive mechanism. Instead of using nuclear materials, it relies on magnesium hydride, which stores hydrogen at a much higher density than conventional pressurised tanks. When detonated by a standard explosive, the
magnesium hydride
undergoes rapid thermal decomposition, releasing hydrogen gas.
The gas mixes with air and ignites, creating a blazing fireball that can burn at temperatures exceeding 1,000°C. This intense heat persists for over two seconds, making the device far more effective in terms of sustained damage than conventional explosives.
'Hydrogen gas explosions ignite with minimal ignition energy, have a broad explosion range, and unleash flames that race outward rapidly,' said Wang Xuefeng, a lead researcher at the CSSC. The sustained heat can melt materials like aluminium alloys, offering a strategic advantage in targeting specific military assets or infrastructure.
Test results and military applications
The test, conducted under controlled conditions, showed that the device could generate peak overpressure of 428.43 kilopascals at two meters, around 40% of TNT's blast force, but with far more significant heat damage. The bomb's unique feature is its ability to create a self-feeding combustion loop, which means it can continue producing intense heat after initial detonation, devastating large areas.
Live Events
The weapon's potential military applications are wide-ranging: from denying the enemy access to strategic routes by incinerating roads to precisely targeting critical infrastructure such as power stations or communication hubs.
This weapon is not only a significant military advancement but also an example of China's growing expertise in energy-based weaponry. The bomb's sustained heat and ability to target specific points, without indiscriminately affecting a broad area, allow the PLA (People's Liberation Army) to carry out precision strikes on high-value targets.
The role of Magnesium Hydride
Until recently, magnesium hydride was only produced in small quantities, due to its highly reactive nature. However, China has invested heavily in scaling up its production capabilities. A new facility in Shaanxi province is now able to produce 150 tonnes annually, using a novel "one-pot synthesis" method developed by the Dalian Institute of Chemical Physics. This breakthrough not only makes the production of magnesium hydride safer but also more cost-effective, which is a crucial factor in mass production for military applications.
China is exploring additional uses for magnesium hydride, including as a power source for
submarine fuel cells
and long-endurance drones. The material's potential as an energy source is expanding beyond explosives, indicating that China's military strategy includes integrating clean energy solutions into its weaponry.
China's military modernisation and clean energy focus
This test comes amid China's broader military modernisation efforts, which are increasingly incorporating clean energy technologies. The country has been upgrading its fleet of warships with electric propulsion systems, including advanced vessels like the Type 055 Renhai-class cruisers. Additionally, China has made significant strides in aerospace with the development of eco-friendly propulsion technologies. In 2023, it launched the world's first methane-powered rocket to reach orbit, a feat that underscores its ambition to lead in sustainable military technology.
The timing of this development is significant, as tensions rise between China and Taiwan. Beijing has ramped up its military presence around Taiwan, viewing any external support for the island as a direct challenge to its sovereignty. The increased military activity follows rising US arms sales to Taiwan and high-profile visits by American officials. This month, China conducted large-scale drills, including live fire exercises, further heightening tensions in the region.
China has made it clear that it sees any intervention in Taiwan's affairs as interference in its internal matters, and has warned the US against providing military aid to Taiwan. Despite these warnings, the US has reaffirmed its commitment to Taiwan, pledging continued support and engaging in joint military exercises with regional allies.
