Regasification
-Warm the gas in a
controlled environment
- Either a big plant or
small ones
-Small plants: from 23
to 1500m3, from 400
000 to 10M$.
- Big plant: from 100
000 to 1M m3, around
500M$.

Transportation by semi-trailers
• Size: 50 m3 of LNG per truck so 0.3GWh
• 800km of road from Hammerfest to Kiruna or to
Lulea
• 1.5 hours for loading and same unloading
• Cost: 440 000 $
• This option Needs:
– 330 trucks at the same time for 6TWh per year!!
– Many small re-gasification plant
• But the cost doesn’t depend of the demand

Transportation by trains
• Size: 30 wagons per train, one wagon transports 110 m3 of
LNG so 690MWh
• 500km of railway between Narvik and Lulea
• 2 travels per week per train maximum to distribute all
destination so 2TWh per year
• Cost: 135$/day/wagon
• This option needs:

One ship between Hammerfest and Narvik
3 trains for 6TWh
One tank per destination because the train can’t wait
Some trucks for the industries far from the railway
Many small re-gasification plants

Transportation by ship

Size: between 40 000 and 200 000 cubic meter of LNG
125 000 m3 of LNG represent 750GWh
4000km from Hammerfest to Lulea so 1 week
For 6TWh we need 8 ships per year, one ship every 45 days
One ship consumes 1080 tons of gas per travel
Cost: 150 millions $
This option needs:
– One ship
– One big terminal next to Lulea
– A network of pipeline to distribute gas to each industry

Transportation by pipeline

Pipes, compression stations, valves…
The gas is moved by the pressure gradient
The pressure is around 70bars
For 10TWh/year, we need a 8” main pipe
For 40TWh/year, we need a 16” main pipe
Power installed: 11MW for 10TWh, 50MW for 40TWh
Nearly no leakage, pipeline buried, very few accidents
No terrorism in Northern Scandinavia
Compressors driven by electrical motors
Compressors themselves environmentally friendly

Conclusion
• Demand of roughly 6TWh per year at the moment
• Either on environmental or economical point of
views, the best way is to start with trucks until 1TWh,
then to continue with pipelines
• The size of the pipeline will depend on the demand
for the next 30 years
• Trains could be used until 8TWh during the
construction of the pipeline
• Ships are too expensive compared to the others
