China's first self-developed hydrogen-powered urban?train completedoperational tests on March 21 in Changchun, Jilin?province in northeast China, marking a breakthrough in the hydrogen application in rail transition.
On a test track, it achieved a full-system, full-scenario and multi-level performance verification at a speed of 160 km per hour.
The train, developed by CRRC Changchun Railway Vehicles, uses a hybrid power supply scheme to improve energy efficiency. Its hydrogen energy propulsion system provides a strong and long-lasting power source.
Test data showed that the average energy consumption per kilometer of the train is only 5kWh/km, and and the maximum cruising range is more than 1,000 kilometers.
The actual performance of the hydrogen train at -25℃ to 35℃ ambient temperature has been verified?by researchers,?and all the test results meet the design requirements.
Chinese researchers used a lunar soil simulant to make "lunar bricks" that are more than three times stronger than the standard red bricks or concrete bricks. This breakthrough is promising for constructing strong lunar bases in the future.
