Advantages of LNG

Compared to LPG and CNG, the advantages of LNG as a substitute automotive fuel are as follows:

(1) Clean and eco-friendly. As a vehicle fuel, LNG must first be vaporized by a vaporizer and then enter the engine in a gaseous state for complete combustion, resulting in extremely low levels of harmful substances in the exhaust, making it highly clean and environmentally friendly.

(2) High calorific value per unit price. Compared to other fuels, LNG offers a lower price and higher calorific value per unit. The low-temperature characteristics of LNG can lower the temperature of the mixed gas and the combustion temperature, improving the engine's thermal efficiency. Therefore, LNG has strong economic and applicability.

(3) High safety. LNG fuel tanks typically allow for a working pressure of 1.586 MPa, with vehicle-mounted LNG tanks often utilizing double-layer metal vacuum powder insulation or double-layer metal vacuum spiral insulation structures, which offer high thermal insulation efficiency and can maintain a longer period without venting.

(4) Easy to Install. Compared to CNG refueling stations, LNG refueling stations require less land, produce no noise, and have lower operating costs. The initial investment for setting up an LNG station is over 30% less than that for a CNG station, and it can reduce daily operation and maintenance costs by more than 50%. As LNG refueling stations are not limited by natural gas sources and pipelines, they can be designed as fixed stations for natural gas or skid-mounted, offering strong mobility.

(5) High efficiency in cold energy recovery. LNG is stored and transported at atmospheric pressure and low temperature, releasing a large amount of cold energy during gasification. Currently, the cold energy recovery rate of LNG can reach 50%, with 1 cubic meter of LNG capable of recovering 960 to 1095 MJ of cold energy. For instance, a refrigerated truck absorbs an average of 56.16 MJ of heat daily during operation. To absorb this heat, a standard diesel refrigeration system would require about 15 liters of diesel. However, in an LNG vehicle, the cold energy released from vaporizing 143 liters of liquefied natural gas can fully absorb the 56.16 MJ of heat, resulting in significant economic benefits. Utilizing LNG cold energy for vehicle air conditioning or refrigerated trucks eliminates the need for a dedicated refrigeration system, saving energy and reducing noise pollution from mechanical refrigeration.

(6) Wide Application Range. By adding high-pressure pumps and high-pressure gasifiers to the LNG fueling system, an LNG-to-CNG fueling station can be established, enabling direct conversion of LNG to CNG. The fueling station can service both LNG and CNG vehicles, thus avoiding the need for CNG vehicle fuel system modifications and eliminating the limitations of CNG fueling stations due to natural gas sources and pipelines. The scalability of the LNG fueling system further expands the applicability of LNG.
