At Sarlin, we have been asking the question for decades: why liquefied natural gas (LNG)? LNG is often connected only to fossil natural gas, which of course it is. For us, LNG is methane, liquefied biogas or natural gas. In the future, biogas will be the most common. We look at it from an environmental point of view more broadly than just from the CO2 emissions perspective. Methane, for example, replaces the use of fuel oil and and liquefied petroleum gas (LPG), and thus directly reduces CO2 emissions. Particulate emissions are also of great importance – they are almost non-existent from the use of methane.

Sarlin has almost 30 years’ experience in gas energy technology; liquefied natural gas (LNG) / Liquid to Compressed Natural Gas (LCNG), compressed natural gas (CNG) and liquefied biogas (LBG). We are involved as an expert in, for example, the preparation of the design guidelines for the gas filling stations of the Finnish Gas Association.

We started to supply biogas pumping stations in 1994. The first gas filling station for vehicles was completed in 2005, and the first LNG filling station in 2015. We have developed also LNG evaporation stations, biogas processing plants and the LNG customer terminal which will be introduced this year. The first LNG evaporation plant was completed in 2018 in Lieksa and now the fourth evaporation plant is nearing completion. Our service offering includes LNG trailers that can be used to transport LNG to customer tanks. For example, B-link trailers have a transport capacity of up to 80 m³.

Total LNG solutions from Sarlin

Sarlin is responsible for the overall design and implementation of LNG plants, including automation. We take care of official inspections and the necessary documents, such as explosion protection documents and operating and maintenance instructions.

Our facilities and products are safe, CE marked and tested before delivery to the site. Our total LNG service also includes remote monitoring and maintenance from pre-service to operation. Our service network covers the whole country.

LNG is the energy of the whole society

Why do we invest so much in LNG technology? The answer is clear: LNG is a versatile energy solution that benefits the entire industry and the environment. Traditionally, each company has its own oil tank in an industrial area, but an LNG tank can be shared by many consumers. When infrastructure is developed in a sustainable direction, there is also enough energy from the tank for local networks, for example. And the same energy can be refueled in both heavy-duty vehicles and passenger cars in the area.

The wider utilization of LNG is represented by the joint project of Kainuun Voima and Rohe Solutions, which will be completed this year. In addition to the evaporation station, the customer terminal has readiness for refueling gas cars and heavy vehicles.

LNG is one of the most environmentally friendly energy sources. When burned, LNG releases more than 20 percent less carbon dioxide than fuel oil. The gas burns cleanly, it is sulfur-free and nitrogen oxide emissions are low. Biomethane, or CBG/LBG, is a carbon-neutral fuel. LNG and LBG require less volume for transport than their gaseous forms. When liquid, they are only six-hundredths of the volume of gaseous methane. The use of LNG/LBG as fuel for heavy vehicles will significantly reduce traffic emissions. The gas burns cleanly and does not generate soot or other dangerous small particles. Therefore, LNG is good.
