Frequently Asked Questions
Q: What is the primary difference between L-CNG and traditional CNG stations?
Traditional stations rely on massive compressors to pressurize gas, while L-CNG uses low-temperature pumps and natural vaporization, resulting in lower energy costs, smaller footprints, and higher safety.
Q: How does L-CNG improve transportation costs?
LNG has a much higher energy density than CNG. A single LNG tanker can supply multiple sub-stations, reducing the number of trips and total vehicle weight compared to CNG tankers.
Q: Is it possible to convert an L-CNG station to a full LNG station later?
Yes, one of the key advantages of L-CNG equipment is its flexibility. It can be modified to a full LNG filling station with minimal additional investment as demand grows.
Q: What are the safety benefits of L-CNG storage?
LNG is stored at very low pressures (typically 7-8 bar), whereas traditional CNG is stored at extremely high pressures (around 200 bar), significantly reducing the risk of high-pressure ruptures.
Q: Does L-CNG require complex filtration systems?
No. Due to the liquefaction process, the gas purity is naturally very high, meaning the system can operate efficiently without expensive dehydration or filtration devices.
Q: What is the difference between fast-fill and time-fill stations?
Fast-fill stations refuel vehicles in 3-10 minutes for public use, while time-fill stations refuel slowly over several hours, ideal for private corporate fleets with overnight schedules.
