Nowadays, the global environmental pollution is intensifying, especially the automobile exhaust emission has seriously affected the atmospheric environment. Many countries have raised the vehicle emission standards, which has also prompted the major automobile enterprises to focus on developing new technologies for this purpose. Under the background of the increasingly vigorous development of hydrogen energy, the hydrogen fuel cell vehicle (hfcv) came into being. Its characteristic is that it uses high-purity hydrogen to supply on-board fuel cell power generation to drive the vehicle. The final product of this way of power generation by chemical energy is water, which can achieve zero emissions. Heavy trucks are often used as the main means of transportation for trunk logistics under the rapidly expanding application demand of China's logistics industry. The characteristics of high emissions and large fuel consumption make the market demand for heavy trucks to transform to hydrogen fuel cell power increasing. However, the promotion and use of this clean energy vehicle is seriously restricted by the hydrogen production, hydrogen supply and hydrogenation system, resulting in a sharp increase in the cost of hydrogen.

In the process of hydrogen energy development, scholars and experts have gradually realized the basic law of human energy development: gas is not the ideal energy carrier for human beings at present. Compared with liquid energy with high energy density, pipeline transportation and long-distance transportation, it is more suitable to become an energy carrier. On the other hand, although the use of high-pressure hydrogen tanks has a certain market space, the potential safety hazards of hydrogen can not be ignored, especially on high-speed mobile vehicles. Once safety problems occur, they may lead to serious consequences.

Combined with the current infrastructure and engineering technology, methanol is the most ideal hydrogen rich liquid raw material. It is a compound of coal, oil and natural gas. One liter of methanol on the vehicle is equivalent to two liters of liquid hydrogen. It only needs an online conversion device to realize immediate production and production, and can solve the problem of high energy consumption caused by hydrogen condensation. This means that methanol can combine the efficiency of fuel cells with the advantages of liquid fuel. More importantly, the supply chain of methanol in China is complete. Using methanol as raw material for hydrogen production in China has low risk of being affected by the international market, which is in line with China's national conditions.

With its unique strategic vision, Guangdong nengchuang Technology Co., Ltd. accurately grasped this technical idea. Relying on the technical accumulation and experience of the team over the years, Guangdong nengchuang Technology Co., Ltd. integrated the "methanol reforming hydrogen production technology" and "fuel cell power generation technology" to meet the needs of different scenarios, developed and manufactured various hydrogen production equipment and hydrogen power generation equipment, breaking through the safety technology bottleneck of "hydrogen production, storage, transportation and charging". After the restructuring in 2018, the company cooperated with the world's most advanced hydrogen production technical force to set up laboratories in the mainland and Hong Kong to jointly carry out R & D work and implement production in the mainland.

According to the working characteristics of heavy truck logistics vehicles, Guangdong nengtron technology has carried out a large number of relevant research and technical research. In order to meet the strong power demand of heavy truck models, constantly break through the technical bottleneck, and finally develop a methanol water hydrogen generator with a hydrogen production capacity of 650l/min-1200l/min. Surprisingly, the volume and hydrogen cost of the methanol water hydrogen generator are only 1/3 of the hydrogen tank with the same power generation capacity, and the use pressure of hydrogen is reduced to 0.17mpa, making the use of hydrogen more safe and reliable. Their technicians kept improving. In order to face the practical application of heavy trucks, they also solved the problem of starting and stopping the hydrogen generator. The average starting time and cooling time of similar models developed in the industry were 8 hours and 10 hours, which were greatly reduced to less than 30 minutes and 1 hour.

The goal of Guangdong nengchuang technology is more than that. On the way to develop the world's most advanced methanol water hydrogen fuel cell powertrain system, they will design a fully automated and intelligent production line to further reduce costs, improve the powertrain, continue to reduce the volume and weight of the hydrogen generator, aim at a longer endurance mileage and achieve full life cycle monitoring. It is expected that the production line will be put into operation in 2021, and 5000 sets of power assemblies will be realized in that year; 10000 sets in 2022; In 2023, it will reach 100000 sets; Achieve the short-term goal of 30billion output value of vehicle powertrain within three years.
