From leak detection robot to roaster, a variety of advanced hydrogen products were showcased at China International Hydrogen Congress and Expo (CIHC 2026) in Beijing.

The three-day exhibition, which concluded on Friday, brought together more than 500 companies from 14 countries and regions to display innovative achievements across the industry chain, from core materials and equipment manufacturing to end-use applications.

One of the most eye-catching exhibits is China's first intelligent robot designed for detecting hydrogen leaks.

With six axes, a high-definition camera, and an infrared monitoring sensor that can detect temperature changes, the robot is capable of searching for hydrogen leaks in a detailed way.

Another exhibit grabbing a lot of attention was a model of the world's only gas-turbine engine capable of using hydrogen, ammonia, and natural gas -- it can seamlessly switch between using one fuel and the other without shutting down.

The eight-megawatt gas turbine engine, which is about three meters long, can be transported by truck, making it particularly suitable for emergency power generation during disaster relief operations.

Despite its small size, it can generate 70 million kilowatt-hours of power annually to meet the electricity needs of 30,000 households.

Another exhibit that generated a strong interest was a hydrogen engine.

With such an engine, a vehicle can perform much better in the long-haul, heavy-duty freight transport compared to counterparts powered by gasoline or electricity.

It can travel approximately 1,000 kilometers on a single hydrogen refueling, with refueling time roughly taking the same as gasoline.

Besides, it can enable drivers to start the vehicle rapidly in temperatures as low as -40 degrees Celsius, making it competitive in the northeast China region and southwest China's Xizang Autonomous Region, which are known for freezing temperatures during winter.

A hydrogen-powered drone was also on display.

Equipped with as much as a 20-liter high-pressure gas cylinder, it has a flight range of up to 3.5 hours, making it suitable for long-haul, long-distance operations, such as deep-sea patrols, desert operations, and forest fire prevention.

Exhibitors said the drone completed a 150-minute flight with a 4-kilogram payload in temperatures as low as -25 degrees Celsius during a scientific expedition to Antarctica last year.

And for those loving bicycle riding, an innovative hydrogen-powered bicycle was on display.

The bike is fueled by solid hydrogen stored in a green-colored cylinder under its saddle, which instead of containing the gaseous state of hydrogen, holds hydrogen storage alloys such as rare earth elements. Once hydrogen enters the cylinder as gas molecules, they react with the alloys and transform into an atomic solid state. Such transformation increases the cylinder's hydrogen storage capacity by more than 10 times.

One single cylinder can store roughly 110 grams of solid hydrogen, allowing a bike rider to travel a distance of 110 kilometers.

Quite a few visitors tested out a roaster which makes coffee with hydrogen.

Exhibitors said in addition to making water taste better, small hydrogen molecules help accelerate the breakdown of caffeine, effectively relieving symptoms of palpitations and making coffee safe for caffeine-sensitive individuals to drink.

Besides, molecular hydrogen acts as an antioxidant and activates free radicals in blood, which to some extent can alleviate fatigue caused by staying up late and overworking.
