Problems solved by technology

High-pressure gaseous hydrogen storage is widely used, easy to operate, low in cost, and fast in charging and discharging hydrogen, but it requires heavy pressure-resistant containers, consumes a lot of hydrogen compression work, and has unsafe factors such as hydrogen leakage and container explosion.
Cryogenic liquid hydrogen storage has a wide range of applications in hydrogen refueling stations around the world, but its application in vehicle-mounted systems is immature, and there are potential safety hazards
In addition, limited by technology, the cost of domestic liquid hydrogen application is very high
