As tensions between China and Taiwan escalate on a daily basis, China's recent advancement in military technology has introduced a new layer of complexity and uncertainty. This latest development involves the creation of a non-nuclear hydrogen bomb, which raises significant questions regarding the regional security dynamics.

In April, researchers at the China State Shipbuilding Corporation’s (CSSC) 705 Research Institute successfully created a controlled environment to detonate a hydrogen explosive device. This innovative bomb, weighing 2 kg (4.4 lbs), achieved a firing temperature of 1,000 degrees Celsius (1,832 degrees Fahrenheit) for a duration of two seconds. Remarkably, this time is 15 times longer than any conventional TNT blast, yet it uses no nuclear materials.

The breakthrough lies in the bomb's utilization of magnesium hydride, a compound that can store hydrogen far more efficiently than traditional pressurized tanks. Initially, magnesium hydride was developed to supply hydrogen to off-grid locations, allowing for the powering of fuel cells for clean energy and heating.

Wang Xuefeng, a leading research scientist at CSSC, emphasized the bomb's unique characteristics, stating, “Hydrogen gas explosions ignite with minimal ignition energy, have a broad explosion range, and unleash flames that race outward rapidly while spreading widely.” This suggests that the bomb’s destructive potential could be significant.

The mechanism of the bomb's operation involves the rapid breakdown of magnesium hydride when ignited. This decomposition, triggered by heat, releases hydrogen gas which then combusts, resulting in an extended fireball that can cause severe damage. According to researchers, the bomb's heat output far exceeds that of TNT, as its fireball burns long enough to melt aluminum, contrasting sharply with TNT’s brief 0.12-second flash.

Research findings indicate that the bomb could serve as a potent directed energy weapon. Tests revealed that the blast’s overpressure reached 428.43 kilopascals at a distance of two meters, which is about 40% of TNT’s pressure, but with a considerably broader range of heat impact.

The researchers have also contemplated various military applications for this new weapon. It could potentially be used to engulf wide areas in intense heat or focus its energy on high-value targets, leading to significant destruction. The study detailed how the chain reaction begins when shock waves from the explosion break magnesium hydride into minuscule particles, initiating thermal decomposition. This process quickly produces hydrogen gas, which, upon mixing with air, ignites and creates a self-sustaining cycle of combustion.

While the research paper provided in-depth technical details, it did not disclose the source of magnesium hydride utilized in the experiments or clarify the specific military contexts in which the People's Republic of China might deploy this formidable weapon. Historically, the production of magnesium hydride has been challenging, with lab settings only managing to produce a few grams daily due to the extreme temperatures and pressures required, as well as the risks of catastrophic explosions if exposed to air.

In the context of international nuclear policy, China has maintained a “no first use” policy regarding nuclear weapons since its first atomic test over 60 years ago. However, this year, the country has opened a new production facility in Shaanxi that can annually produce 150 tonnes of magnesium hydride. This facility was developed by the Dalian Institute of Chemical Physics, which employs a cost-effective “one-pot synthesis” method, as noted by the Chinese Academy of Sciences.

As China continues to enhance its military capabilities with advanced weapons like the non-nuclear hydrogen bomb, the already tense situation in the Taiwan Strait is further exacerbated, fostering concerns about the possibility of escalated conflict and the potential for military invasion.
