On April 12, tianyancha app showed that BYD Co., Ltd. applied for and obtained a patent authorization for "gas tank mount, hydrogen storage device and car".
The patent abstract shows that the present utility model patent belongs to the field of fuel cell vehicle technology, the gas tank mount comprises at least one mounting unit, the mounting unit comprises a mounting cylinder, a base, a pressure reducing valve and a locking device. The gas storage tank mount of this application adopts push-pull type loading and unloading gas storage tank, which is quick and easy to disassemble and replace.
It can be seen from the patent introduction that it is more like a convenient hydrogen replacement technology, "the gas tank mount adopts push-pull loading and unloading gas tank, disassembly and replacement is quick and convenient", similar to the power exchange patent developed by Weilai Automobile in the early days.
From the perspective of the popularity of hydrogen fuel vehicles, the cost of building a hydrogen refueling station is about equal to ten gas stations and thousands of charging stations, and the high cost has led to the difficulty of popularizing hydrogen refueling stations, and BYD's patent is expected to solve the problem of hydrogen replenishment.
In addition, the policy is also increasing the development of hydrogen.
In 2001, the "three vertical and three horizontal" strategy including fuel cells in the 863 plan was established.
In 2020, the Ministry of Science and Technology launched the national key research and development plan "Renewable Energy and Hydrogen Energy Technology" key special project, which will focus on breakthroughs in common key technologies such as proton exchange membranes, gas diffusion layer carbon paper, vehicle fuel cell catalyst batch preparation technology, air compressor durability, and high-reliability stacks. The National Energy Administration has listed hydrogen energy and fuel cell technology as a key task in energy technology and equipment during the "14th Five-Year Plan" period.
In addition to China, developed countries or regions have actively developed the "hydrogen energy economy" and formulated development plans such as the Comprehensive Energy Strategy (the United States), the EU Hydrogen Energy Strategy (EU), and the Hydrogen Energy/Fuel Cell Strategy Development Roadmap (Japan) to promote the research and development, demonstration and commercial application of fuel cell technology.
In this regard, some industry insiders said that the energy form of the new energy era is diverse, and hydrogen can be widely promoted as a storage medium for natural energy.
In addition, studies have shown that hydrogen energy and hydrogen fuel cell technology are expected to be applied in large-scale applications in the fields of automobiles, portable power generation and fixed power stations, and are also important technical alternatives for aerospace vehicles and ship propulsion systems.
However, from a technical point of view, the popularization of hydrogen energy also faces a series of challenges such as low production costs (basic materials such as electrolytes and catalysts), structural compactness, durability and longevity.
summary:
BYD once again preemptively laid out the hydrogen energy field, but whether it can replicate the long-term layout in the field of electric vehicles this time, perseverance, and long-term success, it remains to be seen.
