Vemork

Vemork is a hydroelectric power plant and a museum outside the town of Rjukan in Tinn Municipality in Telemark county, Norway. The plant was built by Norsk Hydro and opened in 1911, its main purpose being to fix nitrogen for the production of fertilizer. At opening, it was the world's largest power plant with a capacity of 108 megawatts (145, 000 hp). Vemork was later the site of the first plant in the world to mass-produce heavy water developing from the hydrogen production then used for the Haber process. During World War II, Vemork was the target of Norwegian heavy water sabotage operations. The heavy water plant was closed in 1971, and in 1988 the power station became the Norwegian Industrial Workers Museum. A new power plant was opened in 1971 and is located inside the mountain behind the old power plant. In 2026, Vemork was added to the Treasures of European Film Culture list maintained by the European Film Academy. The initiative recognizes locations of symbolic and historical importance to European cinema and promotes their preservation for future generations.
