As a vehicle fuel, LNG (liquefied natural gas) has the advantages of high octane number, good anti-knocking performance, low engine loss, low fuel cost, and good environmental performance as compared with conventional fuels. Therefore, in foreign countries, the R&D and application of LNG commercial vehicles have been promoted very early.
Used in the field of commercial vehicles
Taking the United States and Germany as examples, the promotion of LNG vehicles has been going on for many years. It is understood that currently operating LNG vehicles are mainly commercial vehicles, such as city buses, urban engineering vehicles, sanitation vehicles, and logistics transportation companies. This is primarily because commercial vehicles have a large amount of traffic, high usage rates, and natural gas prices are cheaper than fuel. Second, LNG vehicles have smaller emissions. LNG vehicles are less polluting than large amounts of particulates emitted by diesel engines and noise pollution caused.
In the United States, most LNG models currently used are logistics vehicles. In the promotion of the use of heavy-duty trucks in the medium and short distances, LNG vehicles are mainly based on the way that single cylinders are placed vertically on both sides of the frame, and ignition modes can be selected. You can also choose HPDI's hybrid compression ignition (similar to diesel engines). For example, most of the medium and short-distance vehicles used by the UPS Logistics Group use the HPDI type. This type of diesel is being recognized by the developed countries as the type of control for pre-combustion, ignition and ignition of natural gas. As early as 2011, UPS purchased 48 vehicles. LNG trucks were put into the company in Lake Ontario, California. At the same time, the City Transport Department in New York also operates natural gas buses. Telecom companies Verizon Communications Inc. and AT&T Inc. are also using natural gas-powered trucks.
In Germany, the large logistics company, Hellmann Logistics, began trials of LNG-fueled heavy trucks in the fall of 2012 and carried out a four-week road transport. Since then, LNG trucks have also opened up the market for German LNG logistics providers.
Road tests show that LNG trucks can perform tasks well. René Stocker, head of Han Hong Logistics, said that trials have proven that compared with diesel vehicles, LNG vehicles can significantly reduce CO2 emissions while other harmful substances (such as carbon particles). And emissions of nitric oxide and other substances are almost negligible.
Natural gas trucks have become a new trend in the world. Compared with traditional diesel trucks, natural gas trucks are more environmentally friendly, have lower greenhouse gas emissions, and operate at lower noise levels. Although prices are higher than diesel trucks, they are far from From a point of view, the advantages of natural gas trucks will become more apparent today as oil prices increase.
In addition to the United States and Germany, the development of natural gas vehicles in countries such as France, Spain, the Netherlands, and Portugal is also mainly concentrated on commercial vehicles, including buses, logistics vehicles, and garbage trucks.
Policy Guarantee LNG Vehicle Promotion
Similar to our country, the promotion of natural gas vehicles through policy support is also one of the means of some countries. For example, the purpose of promoting LNG vehicles can be achieved through tax deductions and subsidies. In Sweden, the road tax paid by natural gas vehicles is about 3000 kroner (about RMB 2862) lower than that of diesel vehicles. In Stockholm, the capital of Sweden, from Monday to Friday from 6:30 to 18:30, every vehicle entering and exiting the city must pay a traffic jam, but natural gas vehicles and other energy-saving and environmental-friendly vehicles can be exempted from traffic jams. Up to about 14,400 kroner can be saved. In Pakistan, the customs authorities are exempt from taxes on imported natural gas equipment, vehicles, and modified parts, and the tax department also exempts natural gas vehicles from sales tax. In Bangladesh, the introduction of gas station equipment, retrofit parts, and natural gas vehicles enjoy tax exemptions, and banks and leasing companies can provide loan support for retrofitting natural gas vehicles. The Asian Development Bank has helped the city of Dhaka, the capital of Bangladesh, to purchase 10,000 sets of natural gas vehicle modifications and vehicle cylinders at one time. In Thailand, not only preferential tax policies are applied to natural gas vehicles, engines and modified parts, but also the tax rate is first reduced from 40% to 20% and finally to 0%, and the Thai government will subsidize 10,000 yuan for each natural gas vehicle converted. Thai Baht (approximately RMB 2122).
In the process of developing natural gas vehicles, Croatia has made new explorations in its organizational form and provided references for other countries. In 2009, Croatia established the “Environmental Protection and Energy Efficiency Fund Financing Agencyâ€. After the organization was established, it mainly passed two measures to promote the development of the clean energy auto industry. The first is to increase the use of passenger and cargo transportation systems to replace fuels and fuel cells by managing bridge crossing fees, traffic jams, and control of goods transport in urban areas and construction of urban transport facilities. This will promote the development of clean vehicle projects; LNG and CNG vehicles are first used in commercial, public transportation services, driving schools, and public service companies; they support the construction of new LNG and CNG filling stations through financial means. The other is through the cooperation with the Ministry of the Oceans, Transport and Infrastructure, and the Ministry of Economy, Labor, and Enterprise to carry out the "Reduction of Transport Plans Affecting the Quality of the Environment." The main task of the plan is to replace passenger cars, trucks and school buses that do not meet environmental standards, and to provide 50,000 kuna (about 6,750 euros) per vehicle through financing agencies.
