LNG (Liquid Natural Gas - Methane)
Future at the Doorstep
In its development projects, CryoGas also has plans for liquid natural gas as an ideal solution for the supply of urban and suburban public transportation, as well as city delivery vehicles – which together account for 90% of pollution resulting from traffic in cities.
The compressed natural gas (CNG) vehicle filling station is directly connected to the gas line, while a liquid natural gas (LNG, or liquid methane) station is always independent from the primary source of gas supply (gas line, MRS), and liquid natural gas is transported via cryogenic tanks to the storage tank at the station.
CryoGas plans to begin the construction of the first methane (natural gas) liquefication plant as soon as possible, at one of its 4 locations in Belgrade, specifically on the Ibar highway, in the industrial zone, with a capacity of 40 tons per day.
Liquefied natural gas (LNG) can be directly tanked into vehiclesor converted into a gaseous state and tanked into vehicles in the form of compressed gas (LCNG – compressed gas obtained from liquefied natural gas).
The price of liquefied natural gas (LNG, i.e. liquid methane) would definitely be lower than the price of compressed natural gas (CNG), while its use also has other– multiple advantages:
Ecologically cleaner fuel
Natural gas is purified during liquefication, whereby harmful compounds, various hydrocarbons and inert gases are removed, so than nitrogen oxides are not even traceable in vehicle exhaust fumes, while pure liquid methane remains the final product.
Storage of liquefied gas at low pressure
Liquefied natural gas is stored at low temperature and low pressure in special vacuum-isolated tanks, whereby the level of safety for the environment and people is increased in relation to the storage of compressed natural gas at high pressure of 300 Bar.
Significantly lower power consumption for filling the vehicles
While the fast filling of vehicles with CNG requires a compressor with up to 100 kW power (capacity of about 500 m3/h), with accompanying equipment and power supply – the fast filling of pure Methane, obtained from liquefied natural gas (LCNG), requires only about 10 kW for the operation of the high pressure cryogenic pump of the same capacity. The evaporators are atmospheric and do not use additional energy, except for the difference in ambient and liquefied gas temperatures.
The station can also be used for filling liquid methane
In parallel with fuelling a vehicle with compressed natural gas obtained by the evaporation of liquefied natural gas (LCNG), it is also possible to fuel other types of vehicles used for longer distances directly with liquefied natural gas (LNG, i.e. liquid methane) – in special fuel tanks mounted on the vehicle itself.
Lower investment costs
When it comes to the liquefication of natural gas – there are no investments into expensive equipment regarding the gas line, measuring and regulation station, powerful compressors with water cooling, storage space for compressed gas in cylinders, substation, cooling system and the like!For the formation of a station with liquefied natural gas it is only necessary to build a concrete base for the placement of the tank, pumps, and evaporators.
The consumer does not have to pay the cost related to the maintenance of a station with liquefied natural gas
CryoGas installs liquid methane tanks, high pressure pumps and evaporators – as its basic equipment, it maintains this equipment and takes care of its proper operation and functionality.
The use of natural gas as fuel for motor vehicles is gaining in importance and the logical direction of this program is providedfor precisely by the technology of its liquefication, which brings great opportunities when it comes to economic and environmental benefits, including its use in public transportation – even in places where widespread gasification has not even started.
CryoGas is a specialized company in the field of cryogenic low temperature technology with its own know-how and equipment, and it also has a direct cooperation with renowned foreign companies in this field, which enables it to be the carrier of the development of the program of natural gas liquefication and production of high-purity liquid methane, as fuel for motor vehicles.
Taking into account all these facts, there are practically no technical barriers for the wider introduction of natural gas as fuel for public transportation motor vehicles. Ultimately, it is the experiences of foreign countries that testify as to the environmental and economic advantages.
The use of gasoline, diesel and liquified petroleum gas, as fuel for motor vehicles, is directly dependent on limited oil reserves and it is clear that in the near future other forms of energy sources will have to be used, primarily natural gas, the reserves of which are significantly larger and the exploitation of which is far cheaper.
The equipment for the use of liquid natural gas in vehicles is well-known and based on low temperature cryogenic technology (liquid oxygen, liquid nitrogen) –with which CryoGas has many years of experience, and individual components (such as, for instance, the vacuum-isolated storage tank in vehicles)– are already produced in the CryoGas system.
