Qiongzhou Strait transportation new energy vehicle ship successfully docked

On the afternoon of October 8th, under the on-site escort of the Guangdong Zhanjiang Maritime Bureau's "Haixun 0927" ship, the first flatbed cargo ship dedicated to the transportation of new energy vehicles in the Qiongzhou Strait, the "Green Source No. 1" ship, slowly entered the Xuwen Hai'an New Port, marking the successful trial operation of the ship's roll on/roll off transport route in the Qiongzhou Strait. It is reported that the deck cargo ship "Green Source No.1" has a total tonnage of 6731, a net tonnage of 3769, a length of 125.8 meters, and a width of 28 meters. The ship adopts a single-layer deck design, which can carry more than 160 new energy vehicles on a single voyage under full load conditions. The parking capacity is about 60% higher than that of existing passenger and roll on/roll off transport ships. The ship is planned to be deployed on the route from Hai'an New Port in Zhanjiang to Xiuying Port in Haikou. After being put into operation, it will add a new mode of sea transportation for new energy vehicles in the Qiongzhou Strait and effectively alleviate the tense situation of insufficient capacity for new energy vehicle transportation during the peak period of cross sea vehicle transportation in the Qiongzhou Strait.

Dongguan advanced attosecond laser scientific device is about to start construction

The Development and Reform Bureau of Dongguan City recently announced that the highly anticipated advanced attosecond laser facility project has received budget approval from the National Development and Reform Commission, marking the start of construction of this national major scientific and technological infrastructure in Dongguan Songshan Lake Science City. This move marks another scientific milestone for Dongguan after the Chinese Spallation Neutron Source, demonstrating its continued deep cultivation and leadership in cutting-edge technology fields. As a unit of time shorter than femtosecond (1 attosecond=10 ^ -18 seconds), the ultra short time scale of attosecond provides unprecedented opportunities for scientists to observe electron motion and study electron dynamics processes in depth. It is worth noting that the 2023 Nobel Prize in Physics has been awarded to outstanding contributors in the field of attosecond lasers, further highlighting the significant significance of this project in promoting technological progress.

The demonstration project of the National Key R&D Program has started construction

On September 24th, the key technology demonstration project for wide load peak shaving and ultra-low emissions of circulating fluidized bed boilers in the 14th Five Year National Key R&D Plan was officially launched at Shanxi Shuozhou Thermal Power Company. This project brings together top universities, research institutes, and power generation enterprises such as Huadian Shanxi Shuozhou Thermal Power Company, Tsinghua University, and Huadian Electric Power Research Institute. Its aim is to promote the development of circulating fluidized bed boiler technology to a new height of "two highs and two lows" through the integrated application of original technologies, such as efficient collaborative control of sulfur and nitrogen pollutants, rapid load adjustment, and ultra-low emissions of pollutants under a wide load. It will help coal-fired power generation enterprises achieve low-carbon and flexible transformation, and lay a solid technical foundation for building a new type of power system. Given that Shanxi, as an important energy base and pilot province for the electricity spot market, has a new energy installed capacity of over 55 million kilowatts, but the intermittency and volatility of new energy pose challenges to the stability of the power grid, this project will focus on solving the technical problems of circulating fluidized bed boilers during low load and peak shaving processes, increasing the unit load change rate by more than 30% and adding 10% peak shaving potential, thereby significantly enhancing the flexibility, economy, and reliability of coal-fired power generation units, and setting an example for the industry's green and low-carbon transformation.

The first batch of mobile energy storage power stations went online

On the morning of July 11, 2024, the Hainan Railway's cross-sea train ushered in the nation's first feat, and the first batch of mobile energy storage power stations were officially put into use. This innovative measure provides an effective solution to the problem of high temperatures in the carriages caused by power outages during cross-sea ferry operations, and aims to significantly improve passenger comfort. The unique feature of the cross-sea train is that it can carry passengers across the Qiongzhou Strait and achieve a seamless connection between sea and land. Due to the length of the ferry deck, the entire train cannot be loaded directly onto the ship. When trains enter and leave the island, they need to go through a series of carefully designed disassembly and marshalling operations. The train will be split into four groups on both sides of the Taiwan Strait. After a complicated process of dismantling, pushing, pulling out, dismantling, and pushing again, the train will be placed on the train deck of the ferry one by one by the tractor locomotive. Once this process is complete, ferries carry the disassembled train segments across the Channel. After reaching the other side, these train sections are regrouped and restored into complete trains to continue their land journey. The introduction of the mobile energy storage power station is precisely to deal with the problem of power interruption that may occur during this special transportation process, ensuring that the train can still maintain a suitable temperature during the power outage on the ferry, creating a more comfortable and comfortable environment for passengers. travel environment.Editor/Zhang Liyuan

China's export orders for lifting machinery are increasing rapidly

On average, there are 3.2 sets of lifting supporting products per minute, and 38 complete cranes are taken offline per hour. The domestic market share reaches 70%, and related products are used in overseas projects such as the Grand Palace in Paris, France. These data all come from a county-level city in China with a population of less than one million. In recent days, journalists from China News Agency have visited Changyuan City, Henan Province, known as the "capital of lifting machinery", to explore its "past and present" development. In the 1980s, a group of Changyuan people, including Han Xianbao and Cui Peijun, who were good at thinking and changing, saw the market prospects of lifting machinery and invested in lifting machinery maintenance and sales in stores. They founded leading enterprises in the crane manufacturing field, such as Weihua Group and Henan Mining Group. Nowadays, according to the latest official statistics of Nagasaki City, the city produces more than 300000 gantry cranes and 1.7 million sets of components annually, with a domestic market share of 70%. The products are exported to more than 150 countries and regions worldwide. Editor/Zhou Yingwen

Bosch will launch a hydrogen combustion engine for trucks in 2024

German company Bosch has announced plans to launch the first hydrogen combustion engine for trucks in 2024 to complement its existing fuel cell and battery electric products. Hydrogen engines are less efficient than fuel cells, and cars using hydrogen engines require more hydrogen to travel the same distance. But hydrogen-powered internal combustion engines are cheaper and easier to maintain than fuel cells, which are more prone to fouling with dirt and dust, and require very high-purity hydrogen to operate, proponents say. Bosch says on its website that hydrogen combustion engines represent another option for future powertrains. Especially under challenging environmental conditions, hydrogen internal combustion engines are characterized by robust performance. In other words, hydrogen combustion engines may be more suitable for off-road heavy vehicles, and Bosch's website shows that excavators and agricultural tractors in the construction industry may be the solution for this technology. Analyst Jamie Fox believes that off-road vehicles such as tractors and mine vehicles may be better suited to using hydrogen combustion engines than trucks. Editor/Xu Shengpeng
