About Hamina LNG
Hamina LNG was established with the intention to operate a LNG import terminal in the Port of Hamina. The intention is to connect the terminal to the local gas network of Hamina and the Finnish national gas grid The terminal will open the gas import market in Finland.
Natural gas reserves in the world are significantly higher than those of crude oil, the difference in prices between oil products and gas is vast. LNG import keeps gas prices under control and rising security of provision helps to develop gas consuming economic sectors.
LNG terminal work principles are subject to Natural Gas Act and EC Directives. Traders who are interested in trading with LNG will receive equal rights and transparent conditions by the operator of the gas terminal. According to legislation, operator of the terminal is not allowed to trade with gas.
Hamina LNG Oy is a joint venture between Hamina Energy Ltd, Estonian energy company Alexela and Finnish listed technology company Wärtsilä. Hamina Energy Ltd is a municipal energy distribution company, serving the Hamina Kotka region with supply of electricity, heat and gas and other services. Alexela is a private company with extensive oil, petrochemicals and liquid gases experience from greenfield terminal projects in Estonia, Russia and Norway and is developing the Paldiski LNG regional terminal project. Wärtsilä is a global leader in smart technologies and complete lifecycle solutions for the energy and marine markets.
What is LNG?
Liquefied natural gas or LNG is natural gas (predominantly methane, CH4) that has been converted temporarily to liquid form for ease of storage or transport. Liquefied natural gas takes up about 1/600th the volume of natural gas in the gaseous state. It is odorless, colorless, non-toxic and non-corrosive.
The natural gas is condensed into a liquid at close to atmospheric pressure by cooling it to approximately −162°C. The reduction in volume makes it much more cost efficient to transport over long distances where pipelines do not exist. Where moving natural gas by pipelines is not possible or economical, it can be transported by specially designed cryogenic sea vessels (LNG carriers) or cryogenic road tankers.
Modern LNG storage tanks are typically full containment type, which has a prestressed concrete outer wall and a high-nickel steel inner tank, with extremely efficient insulation between the walls.
Natural gas could be considered the most environmentally friendly fossil fuel, because it has the lowest CO2 emissions per unit of energy and because it is suitable for use in high efficiency combined cycle power stations.
In its liquid state, LNG is not explosive and cannot burn. For LNG to burn, it must first vaporize, then mix with air in the proper proportions (the flammable range is 5% to 15%), and then be ignited, but a leak from a secured tank is highly unlikely.
