The main technical content revised in this standard includes: the addition of content on hydrogen refueling combined stations; adjustments to the pressure limit regulations for CNG refueling station storage facilities; and enhanced environmental protection requirements for fuel stations. Adjustments compared to the 2020 version: Compared to the original national standard "Code for Design and Construction of Automobile Fuel and Gas Refueling Stations" GB50156-2012 (2014 edition), this specification mainly includes the following changes: the standard name was changed to "Technical Standard for Automobile Fuel, Gas, and Hydrogen Refueling Stations"; content on fuel-hydrogen combined stations and gas-hydrogen combined stations was added; adjustments were made to the pressure limit regulations for CNG refueling station storage facilities; and environmental protection requirements for fuel stations were enhanced. Main content of the standard: This specification is divided into 13 chapters and 3 appendices, with main content including: general provisions, terminology, symbols and abbreviations, basic regulations, site selection, internal layout, fuel refueling processes and facilities, LPG refueling processes and facilities, CNG refueling processes and facilities, LNG and L-CNG refueling processes and facilities, fire protection facilities and water supply and drainage, electrical systems, alarm and emergency shutdown systems, heating and ventilation, buildings, landscaping, and construction works.
I usually help friends with car-related issues. The technical standards for fuel, gas, and hydrogen refueling stations in 2021 have undergone significant changes, with safety as the top priority. For example, safety distance requirements have become stricter—new stations must be located farther from residential areas. Explosion-proof measures have been upgraded, requiring the use of automatic monitoring systems that trigger alarms and cut off power in case of leaks. Fire safety has also been strengthened, with multiple fire-resistant barriers required for oil storage tank areas, and hydrogen stations now equipped with hydrogen detectors and emergency hydrogen venting valves. Environmental protection is also taken seriously, with requirements for well-sealed refueling equipment to minimize odor dispersion and wastewater treatment systems that must meet standards. Equipment specifications have been standardized, such as pressure limits for hydrogen pumps to ensure stable operation. Overall, these standards aim to make refueling safer and more reliable for car owners while ensuring stations operate in an environmentally friendly and efficient manner—worth keeping in mind during daily vehicle use.
