LNG și BioLNG
LNG sau GNL (Gaz Natural Lichefiat) este o opțiune practică din ce în ce mai populară de reducere considerabilă a emisiilor pentru camioanele care participă la transportul rutier de mare tonaj. Shell face eforturi pentru a face accesibili carburanți din ce în ce mai curați pentru flota dumnevoastră. Călătoria spre decarbonizare începe astăzi!
Beneficiile LNG
- Gazul natural este cel mai curat combustibil fosil disponibil. Arderea lui produce mai puține emisii și depuneri, iar folosirea lui are o amprentă de mediu mai mică.
- LNG este un carburant care extinde durata de viață a motoarelor de până la trei ori față de un motor diesel. Camioanele cu LNG au nevoie de mult mai puține reparații.
- Camioanele cu LNG sunt mai silențioase cu până la 50% față de cele diesel.
- LNG este mai puțin inflamabil decât motorina și este cel mai puțin periculos carburant din punctul de vedere al riscului de incendii.
- LNG nu este ținut sub presiune și nu există, drept urmare, pericol de explozie.
Beneficiile LNG de la Shell
- LNG de la Shell reduce emisiile de gaze cu efect de seră de la sondă la roată pentru camioane cu până la 22% în comparație cu motorina obișnuită.
- LNG de la Shell respectă toate reglementările EPA și Euro VI. În plus, LNG de la Shell reduce semnificativ oxizii de sulf și pulberile în suspensie la niveluri aflate sub cerințe.
- Stațiile Shell LNG sunt concepute special pentru a elimina evacuarea vaporilor de LNG în atmosferă.
- Cardul de Carburant Shell LNG este acceptat în 2022 în Europa în 135 de locații de-a lungul principalelor coridoare de transport internațional.
- Rețeaua de stații Shell LNG va depăși 80 de stații la sfârșitul anului 2022. Consultați harta stațiilor Shell LNG și partenere din Europa

[Animated sequence]
Aerial view of animated grey gridlines on a white background.
Pull back to wide view of 3D simulation of a city skyline rising out of the gridlined background.
Pan and pull back to aerial view of the skyline, which levels out to two 3D yellow blocks, labelled Population and Demand, still surrounded by a white background with grey gridlines, the blocks casting a shadow in front of them.
Pull back to wide front view of the blocks as four more appear frame-right of the first two. The blocks are labelled 2000, 2010, 2020, 2030, 2040 and 2050, and rise incrementally in height from left to right. The blocks cast a slight grey shadow just in front of them against a white background.
[Narrator]
The world’s population is growing and, for many, living standards will continue to improve. As a result, global energy demand is expected to double by 2050 when compared to 2000.

Population / Demand
[Narrator]
To help meet this demand, gas will form an increasingly important role.
[Text displays]
2000 / 2010 / 2020 / 2030 / 2040 / 2050
[Animated sequence]
Zoom to the blocks as they decrease and disappear into the white, gridlined background.
[Narrator]
Natural gas is plentiful, and it’s the cleanest-burning fossil fuel.
[Animated sequence]
Aerial view of gridlined surface as a simulation of a rotating globe of the earth emerges from the surface, continents visible in a mustard colour and the oceans between in pale blue, the globe casting a faint grey shadow in a south-easterly direction.
[Narrator]
But some natural gas resources are in remote locations: transporting the gas long distances by pipeline can be costly and impractical. The solution?
[Animated sequence]
The simulation of the globe morphs into a teardrop of blue liquid against the white, gridlined background. The drop of liquid rolls downwards and disappears.
[Narrator]
We liquefy the gas by cooling it, which shrinks its volume for easier, economical and safe transportation by ship.
[Animated sequence]
Zoom in on a vertical cylindrical shape, a simulated pipeline, as it emerges out of the white, gridlined background.
Simulated gas particles of many colours float upwards through the pipe, and shadows appear either side of the pipe to simulate the reflection of the pipeline running along the ground’s surface.
Pan down to oblique, horizontal angle of the pipeline as coloured particles flow frame left to frame right, all still against the white background with grey gridlines and shadows.
Pull back to an aerial view of a network of pipes along which particles are flowing, all stemming from one pipe, similar to the shape of a fork, but with many tines.
[Narrator]
So, how is liquefied natural gas produced? Natural gas extracted from the ground contains impurities, water and other associated liquids. First it is processed to clean it. It goes through a series of pipes and vessels where gravity helps separate the gas from some of the heavier liquids.
[Animated sequence]
Pull back and pan to an aerial view of the whole plant, one of the large towers displaying the Shell logo.
Zoom to another section of the plant, showing a single pipeline, through which multi-coloured particles are flowing into a tank.
Zoom to close-up of particles, showing the yellow particles, representing carbon dioxide and hydrogen sulphide, being absorbed into the background, disappearing, leaving green, blue, turquoise and purple particles flowing from frame-left to frame-right.
Blue particles, representing water, next veer towards a faint, grey circular opening in the background, disappearing from the simulated flow of particles.
Turquoise particles, representing mainly propane and butane, also veer towards yet another circular opening in the background, leaving many green and some purple particles, representing methane and ethane respectively.
Pull back to rear view of green and purple particles flowing away and disappearing to the top of frame as a bright white section slowly opens up at the top of the pipeline, still indicated by the white gridlined background.
[Narrator]
Other impurities are then stripped out. The natural gas passes through a water-based solvent that absorbs carbon dioxide and hydrogen sulphide. These would otherwise freeze when the gas is cooled and so cause blockages. Next any remaining water is removed, as this would also freeze. Finally, remaining lighter natural gas liquids – mainly propane and butane – are extracted to be sold separately or used as a refrigerant later in the cooling process. Traces of mercury are also filtered out. Now the purified natural gas – methane with some ethane – is ready to be liquefied.
[Animated sequence]
Zoom to aerial view of a stylised line animation of three heat exchangers, with pipes flowing along the white gridlined background.
Zoom to central exchanger, the coolant, and pan to front view of the coolant’s yellow-rimmed window, showing cold air blasting downwards over a network of pipes.
Zoom to a close-up of the moving particles against the white-grey gridlined background as they decrease in size and cluster together to fill the screen.
Dissolve to aerial view of a beaker containing water, casting a shadow on the white surface, and panning to a front view of the beaker.
[Narrator]
This happens in heat exchangers. A coolant, chilled by giant refrigerators, absorbs the heat from the natural gas. It cools the gas to -162°C, shrinking its volume by 600 times. This turns it into a clear, colourless, non-toxic liquid - liquefied natural gas, or LNG – that is much easier to store and transport.
[Animated sequence]
Tanks and structures rise from the white-grey surface and the beaker becomes opaque and, as we pan to a front view, it turns into an insulated tank, displaying the Shell logo on its front. Pipes running from the tanks towards the foreground appear to flow with blue liquid, the remainder of the background still in whites and greys.
Pull back to aerial view of the plant in the background with an LNG vessel in the foreground, parts of its superstructure coloured in yellow.
The plant structures sink back into the white background as the shot pans down and back behind the stern of the ship. The ship moves rapidly across and out of the frame diagonally from frame-right to frame left.
[Narrator]
The LNG is kept in insulated tanks until it is ready for loading into a specially designed LNG ship or carrier.
[Animated sequence]
Quick pan to aerial view of the LNG vessel connected via pipeline to three tanks, blue liquid flowing from the vessel to the tanks.
Pan 180 degrees to three pipelines flowing out of the three tanks, the substance – now denoted by yellow- flowing rapidly along the pipelines which extend to the city skyline, again against the white and grey gridlined background.
Pull back to aerial view of the city and zoom out.
[Narrator]
When the ship arrives at its destination, the LNG is transferred to a regasification plant where it is heated, returning it to its gaseous state. The gas is then transported via pipelines to customers, providing energy for homes and industry.
