Liquefied natural gas - the marine fuel of the future

The Port of Gothenburg is working actively to promote the use of liquefied natural gas, LNG, as a marine fuel. There are considerable environmental gains to be made from using LNG in shipping. Sulphur and particle emissions are reduced to almost zero and nitrogen emissions are reduced by 85-90 per cent.

Regulations facilitate bunkering
With effect from 2015, vessels can refuel with LNG at the Port of Gothenburg. Bunkering is possible thanks to LNG operating regulations produced by the Port of Gothenburg in collaboration with the Port of Rotterdam.

The regulations cover both bunkering from land using road tankers and ship-to-ship bunkering. Stipulations related to safety zones, weather conditions, bunker vessels, receiving vessels, terminals and other aspects are included in the new operating regulations. 

Environmental benefits
Emissions of sulphur dioxide and nitrogen oxides are a major problem in our area that affects the environment in the ocean and in the air. Changing from oil to gas reduces these emissions significantly. Sulphur and particle emissions are reduced to almost zero and nitrogen emissions are reduced by 85-90 per cent.

Carbon dioxide emissions are reduced by 20-25 percent, but because of methane leakage in connection with combustion, it is debatable if the climate impact is less than when oil is burned. However, the engines are continuously improving, and in the motor industry work is ongoing to reduce methane emissions in connection with combustion.

With the conditions available today, LNG is the best option for large-scale shipping, as the second option is to continue driving on oil. LNG is a good step in the right direction.

Significantly discounted port charge
In order to induce more operators to switch to LNG we have introduced a substantial discount on the port charge. Vessels that run on LNG receive a discount of up to 30 per cent on the port charge. The discount will apply until December 2018. Over a year this would amount to a significant sum for vessels calling at the Port of Gothenburg on a regular basis. 

LNG terminal at the Port of Gothenburg
The EU has identified LNG as an important vessel fuel and requires all major ports in Europe to provide LNG by 2025.

Within a few years, there will be an LNG import terminal at the Port of Gothenburg. The terminal will be operated by Swedegas, which owns the Swedish gas grid, and will be built at the Skarvik Harbour.

The planned capacity is 20,000 cubic metres with potential for expansion in line with market growth. The terminal at the Port of Gothenburg will be run in accordance with the open access principle, which means that any operator that is interested in supplying LNG to the Swedish market can purchase capacity at the terminal. This allows end-customers to purchase LNG at the best price on the world market.

 

Fact file: LNG
LNG is natural gas – mostly methane – that is cooled down to -163°C and converted temporarily into liquid form. This means it takes up 600 times less space and it can be transported efficiently using sea, rail and road tankers.
