The Nynäshamn Receiving Terminal is a further step to make natural gas a common energy utility along the Swedish coastline. Other terminals are planned along the entire Baltic Sea coast. These terminals shall serve smaller communities and users. The LNG (liquefied natural gas)is supplied by small coastal carriers which take it off from the larger terminals such as for example the Risavika Export Terminal near Stavanger in Norway.
The new import terminal, being built by CRYO AB, a specialized company based in Gothenburg, Sweden, has an annual capacity corresponding to 3 TWh, the amount of energy required to heat 150,000 houses. The natural gas is delivered to the terminal in liquefied form by LNG carriers. The facility is able to accommodate carriers up to 160 m long.
Natural gas, which is largely methane gas, liquefies at a temperature of minus 162 oC thereby reducing its volume by a factor of 600. The LNG is stored at the terminal in a so-called full containment tank with a capacity of 20,000 m³.
The tank comprises an inner tank made of a special steel capable of resisting the cold temperatures and an outer containment of prestressed concrete. Provision is made for a further tank in a second phase.
The construction period for the tank was 24 months. The complete terminal became operational in 2011.
