Chart has completed the largest liquefied biogas (LBG) refueling station in continental Europe. Located in Kallhäll, just outside Stockholm, Sweden, the station was engineered and built at Chart’s European technology Center in Děčín, Czech Republic.
Designed to meet the demands of increased traffic of natural gas fueled heavy-duty transport across the region, the station features four LBG and two compressed biogas dispensers, along with cryogenic tanks with a total liquid storage capacity of 4592 ft.3 (130 m³).
The station is directly connected to a nearby biogas liquefaction plant operated by Gasum, enabling the use of locally produced renewable fuel on site. This integrated approach reduces transport-related emissions and supports the development of a circular economy of waste to energy.
Biogas is renewable natural gas produced through anaerobic digestion of organic waste. Like natural gas, it is liquefied to reduce its volume by a factor of 600 making it economical to transport and store. Liquefied natural gas (LNG) and LBG are chemically similar and can be used and blended interchangeably. LBG is therefore a sustainable alternative to LNG. In the heavy-duty transportation sector using LBG instead of diesel provides potential CO2 reductions of >80% on a well-to-wheel basis. LBG and LNG also virtually eliminate harmful emissions of NOx, SOx, and particulates.
