Under the assumption that the LNG filling facility will be set up in the logistics centers of carriers, the partners downsized it so that it can be set up in the parking space of one heavy truck. It is capable of fueling 50 to 60 heavy LNG trucks per day with a fueling time of just 10 minutes per truck. The amount of LNG remaining in the LNG filling facility can be viewed remotely, and by creating a system in which LNG replenishment occurs at the appropriate time with the appropriate amount for the LNG filling facility, the partners plan to establish a stable LNG supply system for the LNG filling facility.
Additionally, CNG filling equipment has been added to the LNG filling facility at the Tomakomai filling station, enabling to fill both CNG(which is used as supplementary fuel for LNG trucks) and LNG.

Unlike trucks powered by electric batteries or fuel cells, LNG trucks have ranges in excess of 1,000 kilometers and sufficient load capacity.
They are expected to be capable of reducing CO₂ emissions by more than 10%^* when compared to diesel trucks. LNG trucks have reduced vibration and noise, and special characteristics include their exhaust being extremely green and their lack of a petroleum smell similar to diesel.
* LNG trucks built by Isuzu Motors Ltd. was used in tests undertaken as part of the Ministry of the Environment's “Low Carbon Research and Development Program," which ran from 2016 to fiscal year 2018. The tests confirmed that the truck had a range of more than 1,000 (primarily highway) kilometers per fill-up in city-to-city transport, and that it also produced less than 90% of the CO₂ emissions produced by diesel trucks that meet Japan's heavy vehicle fuel efficiency standards set in fiscal year 2015.

From 2021 to 2024, Mitsubishi Corporation and Air Water has performed trials using 14 LNG trucks manufactured by Isuzu Motors Ltd. and LNG trailer head manufactured by Volvo Trucks Corp. for the commercialization of the LNG filling facility. With the cooperation of Hokkaido Electric Power Co., Inc., the partners plan to assess the system's overall feasibility towards social implementation and how much it can reduce CO₂ emissions and fuels costs typically generated by LNG trucks. The results of the tests will help the partners to determine whether or not to make the system commercially available. We also conducted mixing the LNG with liquefied biomethane to further reduce CO₂ emissions.

LNG, which fuels LNG trucks, uses a dedicated nozzle and is completely sealed off as it is an extremely cold liquid. In order to avoid the risk of cold burns, etc. due to touching things that have cold areas, LNG fueling workers must wear protective gloves and face guards. In addition, there are safety measures such as the prohibition of handling heat around the Facilities.
Furthermore, the LNG tank in the LNG filling facility is a dual structure, and the risk of an LNG leak is as low as it could possibly be. In the unlikely event that LNG leaks onto the ground, it will vaporize and dissipate as vaporized gas is lighter than air, and it will not contaminate the land or water as LNG is not poisonous.
