my country has made important new breakthroughs in the field of hydrogen rail transit technology. on september 24, cinova h2, my country's first hydrogen energy intelligent intercity emu independently developed by crrc qingdao sifang co., ltd., was officially released at the berlin international rail transit technology exhibition. the vehicle is powered by hydrogen and achieves "zero carbon" emissions throughout the entire journey. in addition, its key performance such as operating speed, passenger capacity, and cruising range are better than similar international products, which will inject new impetus into the green upgrade of non-electrified railway passenger equipment.

hydrogen energy is known as one of the most promising clean energy sources in the 21st century and is also an important development direction for the green transformation of rail transit equipment. crrc sifang has mastered key technologies such as integrated train assembly design, full-operation hydrogen-electric hybrid energy control, and full life cycle safety management, and has successfully realized the engineering application of hydrogen energy in intercity and urban emus.

more advanced: faster speed, more passengers, longer range

liang caiguo, chief designer of crrc sifang, introduced that cinova h2, a hydrogen energy intelligent intercity emu, is equipped with a hydrogen fuel cell, which uses the electrochemical reaction of hydrogen and oxygen to generate electricity for driving. compared with similar international products, it "carries more, runs faster and goes farther".

the train is composed of 4 cars and equipped with a high-power hydrogen fuel cell with a capacity of up to 960kw. it has sufficient power and can operate at a continuous speed of 160 kilometers per hour and a maximum operating speed of 200 kilometers per hour. the train has the longest cruising range in the world, with a cruising range of 1,200 kilometers at a speed of 160 kilometers per hour, 2,000 kilometers at a speed of 120 kilometers per hour, and 3,000 kilometers at a speed of 80 kilometers per hour. at the same time, the hydrogen refueling speed is fast, and it only takes 15 minutes to fill the train with hydrogen once. in terms of passenger capacity, the lightweight body and intensive passenger compartment design have increased the passenger capacity, and the maximum passenger capacity of the entire train exceeds 1,000 people.

greener: each train reduces co2 emissions by approximately 730 tons per year

"as a new type of green rail transit equipment, this train can be called an 'environmental protection expert'," liang caiguo introduced. the entire reaction process of the hydrogen fuel cell on the train only produces water, and the vehicle has "zero" carbon emissions throughout the entire journey, and does not produce any air pollutants. according to an estimated annual operation of 300,000 kilometers, each train can reduce carbon dioxide emissions by about 730 tons per year, which is equivalent to planting 567 acres of trees. at the same time, the train innovates recycling technology to turn wastewater and waste heat into "treasures". the water discharged from the hydrogen fuel cell reaction is purified and recycled to meet the water needs of the entire train, such as passengers washing, effectively saving water. the cooling waste heat of the hydrogen fuel cell is recycled for air conditioning and heating in winter, which is more green and environmentally friendly.

the train has excellent energy consumption performance. it reduces operating energy consumption by adopting advanced technologies such as lightweight and smooth design, efficient permanent magnet traction, and full recovery of brake regenerative energy. when traveling at a fully loaded speed of 160 kilometers per hour, the hydrogen consumption per person per kilometer is less than 0.3 grams.

smarter: intelligent operation and maintenance of all scenarios, from driving to passenger services

not only is it green and environmentally friendly, but it is also extremely "intelligent". the train uses cutting-edge intelligent technology to achieve full-scenario intelligence in daily driving, passenger services, operation and maintenance.

the train is equipped with more than 2,000 data collection points throughout its body. it uses cutting-edge technologies such as digital twins, artificial intelligence, and 5g to build an advanced smart care integrated vehicle-ground intelligent operation and maintenance platform. through comprehensive real-time monitoring, intelligent fault diagnosis, and intelligent maintenance decision-making, it realizes health management of the train throughout its life cycle, improves operational reliability, and reduces vehicle maintenance costs.

the train is equipped with an "intelligent cockpit" with functions such as intelligent push of traction strategies, cockpit voice control, 3d digital interaction, and intelligent fault location, making driving more convenient and safer. entering the train cabin, intelligent services are everywhere. for the first time, intelligent electronic curtains are configured, which can not only adjust the light transmittance, but also realize partition control to better meet the needs of passengers. at the same time, it is equipped with advanced intelligent facilities such as passenger hearing aids, smart interactive windows, digital interactive screens, and wireless wi-fi to create a more technological and intelligent riding experience for passengers.

safer: passed third-party independent security assessment

the hydrogen system of the train has undergone rigorous full-scenario, full-operating condition safety simulation analysis and test verification, and is equipped with multiple safety protection systems such as intelligent detection and isolation protection to ensure vehicle safety. the train's hydrogen power system has passed a third-party independent safety assessment.

for the first time, an online monitoring system for bolt fasteners is installed in key parts of the vehicle running gear, using ultrasonic sensing technology and data analysis algorithms to achieve real-time monitoring and early warning of the bolt tightening status, reducing potential risks.

wider application: meeting the needs of non-electrified trunk lines, intercity and urban passenger transportation

cinova, the "china intercity star", is my country's first intercity emu technology platform. the platform products cover various speed levels of 200 km/h, 160 km/h, 140 km/h and 120 km/h. it has been put into passenger service on more than 30 lines across the country, covering more than 40 cities at prefecture level and above. the hydrogen energy intelligent intercity emu cinova h2 released this time is the first hydrogen-powered train under this platform.

as my country's first hydrogen energy intelligent intercity emu, the train is equipped with a hydrogen fuel cell system independently developed by crrc, which has completely independent intellectual property rights. at the same time, crrc can provide a full-chain system solution for hydrogen energy "production, storage, transmission and use".

the hydrogen energy intelligent intercity emu cinova h2 has a wide range of application scenarios and can be used in non-electrified railway areas at home and abroad to replace traditional internal combustion vehicles. through customized design, it can meet the needs of various types of railway passenger transportation such as non-electrified trunk lines, intercity, and urban areas. as a new type of zero-carbon equipment, the hydrogen energy intelligent intercity emu can effectively reduce carbon dioxide and air pollutant emissions, with significant green environmental protection advantages, which will strongly promote the new green upgrade of non-electrified railway passenger equipment.
