CTOnews.com, April 10, 2023, on April 10, 2023, the annual launch of unpotential Energy with the theme of "H POWER DAY" was held online. Chen Xuesong, president of unpotential Energy under the Great Wall Group, released a series of the latest technological achievements on the product side.

Facing the long-distance transportation scene of hydrogen energy heavy truck, in the field of hydrogen storage application, the dual technical route of unpotential energy "gas hydrogen + liquid hydrogen" is parallel, and the "Jupiter" vehicle liquid hydrogen storage system is launched. The hydrogen storage quality of a single bottle is more than 80kg, the mass hydrogen storage density of liquid hydrogen system is ≥ 8wt%, and the range exceeds 1000km. Key tests such as drop and vibration have been completed in authoritative institutions such as Aerospace Research Institute and China Special Inspection Institute. The comprehensive performance has reached the international advanced level, and the matching Great Wall automobile "New long March No. 1 liquid hydrogen heavy truck" has entered the whole vehicle road test stage.

In the fuel cell field, the unpotential energy "metal stack + graphite stack" dual-core layout, launched the 300+kW expanded graphite plate stack, flexible graphite veneer thickness 0.65mm, the highest efficiency reached 68%, the peak power density exceeded 4.0kW / L, the design life reached 30000 hours, promoting hydrogen energy heavy truck medium-and short-distance transportation to long-distance transportation.

For commercial and passenger use, Unpotential Energy has launched a second-generation 70MPa-57L Ⅳ hydrogen storage bottle suitable for passenger vehicles, with a mass hydrogen storage density of 6.1wt%, far exceeding the US Department of Energy (DOE) target of 5.5wt% for 2025.

At the same time, the platform products include 70MPa-23L, 35MPa-210L and other product series of different specifications and models, the working pressure covers 35MPa and 70MPa, and the mass hydrogen storage density index of some commercial vehicle IV hydrogen storage bottles can reach 6.8wt%. The whole series of products have achieved 100% autonomous control of key core technologies, laying the foundation for promoting the commercialization of fuel cell vehicles.

In view of the difficulty of hydrogenation, unpotential Energy, Liben Energy and CLP New Source have launched the strategic cooperation of "jointly building 100 hydrogenation stations" to lay out Beijing, Tianjin and Hebei, and gradually establish an energy supply system for radiating key areas such as the Yangtze River Delta, Pearl River Delta, Shandong, Henan, Sichuan and Chongqing, Central China and Northwest China.

In view of the problem of integrated services, Weiwei Energy and Hegang Industry, if Science and Technology, Avenue Qiangyuan and Kaiwo Automobile jointly signed 650 hydrogen fuel cell heavy truck strategic cooperation, focusing on the scale of medium-and short-distance logistics and transportation and demonstration projects of long-distance transportation, in order to customize comprehensive solutions to open up hydrogen sources, costs, services, finance and other links, so as to change products from "buy" to "use". Promote the large-scale promotion and application of demonstration scenes.

Finally, in view of the realization of carbon economic value, Unpotential Energy cooperates with CNAC to jointly study the "hydrogen Energy Application carbon Trading Standard" and improve relevant policies, measures, standards and methodology. explore hydrogen energy carbon trading, price index, traceability certification, hydrogen carbon emission reduction market-oriented trading mechanism to enable customers in the industry to achieve more hydrogen energy economic value.
