What is LNG?

Liquefied natural gas (LNG) is natural gas turned into a liquid by cooling to the condensation temperature (-161.5 °C). Being liquefied it takes about 1/600th of the initial volume. Either LNG or CNG can be used as motor fuel.

Since LNG is energy-intensive, it is efficient for high-performance engines with significant fuel consumption. Main consumer segments are heavy trucks, intercity buses, agricultural machinery, quarry machinery, railway and maritime transport.

Efficient motor fuel

Economical motor fuel

When using LNG, fuel costs are 30-50% lower as compared to traditional types of fuel.

- 30–50%

Efficient motor fuel

Eco-friendly motor fuel

LNG engines meet the highest Euro-5 and Euro-6 emission standards. Emissions of LNG engine are significantly reduced: it contains no particulate matter and sulfur (main components of smog). Carbon monoxide and heavy hydrocarbon emissions are reduced up to 65%. Emissions of nitrogen oxides are minimized as well.

Efficient motor fuel

High-tech motor fuel

LNG engine service life is 1.5 times longer compared to a conventional one due to clean composition of natural gas. During combustion LNG does not produce engine deposits and preserves the oil film on the cylinder walls reducing friction and wear. No detonation takes place in cylinders while engine is running that significantly reduces components’ workload.

Key LNG consumers

Heavy trucks, intercity buses, agricultural machinery, quarry machinery, railway and maritime transport will be the key LNG consumers in the near future. By 2030, LNG market share by volume is expected to be 33% for heavy trucks and intercity buses, 27% for maritime transport, 23% for quarry machinery, 9% for railway transport and 8% for agricultural machinery.

Heavy trucks and intercity buses

Heavy trucks and intercity buses will become a key consumer of LNG as a motor fuel. The use of LNG increases its carrying capacity and cruising range (compared to CNG). One-filling range of gas-diesel truck is more than 1,000 km.

Maritime transport

The urgency of using LNG in water transport is due to the toughening of MARPOL requirements for the prevention of pollution from ships. In 2013 the LNG-fueled Viking Grace ferry started its operations along the Turku — Mariehamn — Stockholm route. Zelenodolsk Plant named after A.M. Gorky (the Republic of Tatarstan) is to build two LNG-fueled ships.

Quarry machinery

Quarry machinery fueled by LNG will be used in the areas of mining plant operations concentrated in the following 6 regions: Kemerovo region, Kursk Magnetic Anomaly (Kursk and Belgorod regions), North-West area (Murmansk region and Karelia), Yakutia, Krasnoyarsk Krai and Amur Region. Additionally, the use of LNG as motor fuel ensures continuous operations of trucks for 8-14 hours, and also reduces smoke and toxicity of exhaust gases under the conditions of poorly ventilated quarries.

Railway transport

LNG is used on non-electrified railroad sections. Russian Railways successfully ran the trial usage of gas-turbine locomotives GT1h-001 and GT1h-002 and gas-piston diesel-locomotive TEM19-001. Russian Railways state that damage caused by gas-turbine locomotives usage is 2.5 times lower compared to traditional diesel locos and maintenance costs are also lower.

Agricultural machinery

The segment of agricultural machinery is characterized by strong fragmentation, both geographically and in terms of the number of machinery owners. The segment clearly shows the seasonal demand, so the implementation of LNG is contingent upon development of related consumption.

LNG infrastructure

LNG is produced by cooling natural gas to cryogenic temperatures (approximately -161°C). The liquefaction process is based on cooling natural gas by a sharp decrease of its pressure: natural gas is compressed in compressor units, pre-cooled in refrigerating machines and at the last stage it is expanded by decrease in pressure. The resulting LNG is poured into special cryogenic tanks, where liquefied natural gas can be stored for a long time.

LNG infrastructure

The usage of LNG as a motor fuel has its basement in the development of small scale LNG infrastructure. Small scale LNG plants can be based on gas distribution terminal, CNG fueling stations as well as on self-contained facilities.

LNG infrastructure

There are several types of LNG retail infrastructure: LNG filling stations; LCNG filling stations which provide both CNG and LNG; CNG filling stations with additional LNG storage and fueling equipment. The first stage of the development of LNG retail chain is planned on the highways with the most intensive traffic, such as A-181 Scandinavia: (Finnish border– Saint Petersburg), M10 (Saint Petersburg — Moscow), M7 (Moscow — Ufa — Yekaterinburg — Novosibirsk), М1 (Belarus border— Moscow), М4 (Moscow — Novorossiysk).
