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. Read more: Environmental discounts on the Port tariff.
Rules allow bunkering
Since 2015, vessels can fill the tank with LNG in the Port of Gothenburg. The bunkering is possible thanks to LNG operating regulations developed by the Port of Gothenburg in collaboration with the Port of Rotterdam.
The regulations include both bunkering from land by truck and ship-to-ship bunkering. Requirements for safety zones, weather, bunker vessels, receiving vessels, terminals and more are included in the new operating regulations.
Environmental benefits with LNG
Today, emissions of sulfur dioxide and nitrogen oxides are a major problem in our immediate area that affects both the environment in the seas and in the air. Switching from oil to gas significantly reduces these emissions. Sulfur and particulate emissions decrease to near zero and nitrogen emissions by 85-90 percent.
Carbon dioxide emissions decrease by 20-25 per cent, but due to the leakage of methane (so-called methane emissions) in connection with the combustion, it is debatable whether the climate impact is less than in the combustion of oil. However, the engines are continuously improving and in the motor industry work is underway to reduce methane emissions in connection with combustion.
Given the conditions that exist today, LNG is the best option for large-scale shipping, as the second alternative is to continue to run on oil. LNG is a good step in the right direction.
LNG is natural gas, mostly methane, which is cooled to -163 °, and temporarily converted to liquid. This means that it takes up 600 times less space and can be effectively transported in tanks on a ship, train or truck.
