Methods for providing heat to electric operated LNG plant
Hammerfest LNG plant, located at Melkøya outside Hammerfest, is supplied with heat and power from an on-site combined heat and power (CHP-) plant. This natural gas fired CHP emits more than one million tons of CO2 per year, which makes it one of Norway s largest point emissions. Melkøya is therefore...
