The "dual carbon" goal is emphasized again. Ji Chong Hydrogen Energy's domestically produced fuel cells accelerate the development of hydrogen energy storage and promote the realization of carbon peak

Converting electrical energy into hydrogen energy or other chemical energy has always been considered a large-scale, efficient energy storage solution. Hydrogen energy can be directly used as an energy source to drive hydrogen fuel cell vehicles or burn to release energy. It can also be produced into methanol, ethanol, ammonia or natural gas as needed, achieving higher storage and transportation efficiency and utilization value, and making diversified use of renewable energy.

Fu Yu, chairman of Ji Chong Hydrogen Energy, a technology company focusing on the research and development and industrialization of hydrogen fuel cell stacks with independent intellectual property rights, explained the process of hydrogen energy storage: "Renewable clean energy such as solar energy and wind energy is unstable and difficult to enter the power grid. A large amount of it is discarded, resulting in the long-term reliance on fossil energy for electricity supply, which produces a large amount of carbon dioxide. Hydrogen energy is a new means of energy storage. After clean energy such as solar energy and wind energy generates electricity, it is used to produce hydrogen, store energy in the form of hydrogen, and then release the electricity through fuel cells when it is used."

Currently, Ji Chong Hydrogen Energy is participating in the 2021 China International Hydrogen Energy and Fuel Cell Industry Exhibition

Xue Qikun, an academician of the Chinese Academy of Sciences and president of the Southern University of Science and Technology, said in a conversation with Tesla CEO Elon Musk that using clean energy such as solar energy to generate electricity and then using this electricity to continuously decompose water into hydrogen "ensures that in the future, when fossil energy is basically not used, we can rely on clean energy such as solar cells to maintain the continuous application of the main core technologies created by the three industrial revolutions of mankind."

At present, there are two forms of hydrogen energy storage applications: one is to use fuel cells as automobile power, and the other is to connect fuel cells to the power grid to play the role of peak shaving and valley flattening.

However, the cost of utilizing hydrogen energy is still very high and the technology is difficult, which has led to the fact that the promotion effect of fuel cell vehicles in my country lags far behind that of pure electric vehicles: as of December 31, 2020, only 6,002 fuel cell vehicles have been connected nationwide. How to change the situation of "hot public opinion but cold application"? Fu Yu believes that only by continuously improving performance, life and reliability, reducing costs, and promoting supply security of the entire industry chain, can fuel cells enter the application field better and faster, and truly become a reliable path to achieve the "dual carbon" goal.

In 2020, Ji Chong Hydrogen Energy released the MH170, a domestically produced high-power metal plate fuel cell stack with independent intellectual property rights, which is used to power fuel cell vehicles. Its performance is not only leading in China, but also in the "first group" internationally. Some parameters are even better than the world's top products. As a "powerful player" in the fuel cell industry, Ji Chong has achieved breakthroughs in key core technologies and realized domestic substitution and independent control of fuel cell technology.

The maximum power of the MH170 fuel cell stack has exceeded 160kW, which is the largest single stack power known in the fuel cell field at this stage. It has also achieved a successful start-up at -39°C without an auxiliary heat source, setting a record for unassisted low-temperature start-up of fuel cell stacks in the domestic and international fuel cell fields. The maximum specific power of the MH170 series fuel cell stack can reach 4.7kW/L and 4.0kW/kg. Therefore, under the same stack power, less raw materials are used and the cost reduction space is greatly improved. In addition, the cost of key raw materials can be reduced by continuously improving the efficiency of the production and manufacturing process.

At present, MH170 has passed the national compulsory inspection of the battery stack, and the supporting systems have also completed the national compulsory inspection. Many products are undergoing vehicle commissioning. At the same time, Ji Chong Hydrogen Energy has completed its layout in Shanghai, Beijing, Guangdong, and Henan. Fu Yu introduced that Ji Chong Hydrogen Energy has currently reached cooperation with many customers, and the annual intention order has reached nearly 900 units.

As a new energy storage solution, the imagination of hydrogen energy application is by no means limited to automobiles. Fuel cell stacks are composed of multiple single cells stacked in series. The number of cells can be increased or decreased according to the usage scenario. Multiple stacks can be used in series and parallel for "peak shaving" of power grids and heating of community fuel cell power stations. "This is a market several times larger than the automotive field." Fu Yu revealed, "At present, we have completed a one-to-one strategic agreement with an energy company, and we are expected to bring Ji Chong's stack technology into a larger energy market."
