Ruhrgas

Ruhrgas was one of Germany’s most important gas infrastructure and energy-trading companies during the twentieth and early twenty-first centuries. It originated in 1926 as Aktiengesellschaft für Kohleverwertung, a company established by Vereinigte Stahlwerke AG and Zeche Mathias Stinnes to transport and distribute coal gas produced by coking plants in the Ruhr district. The company’s early business was therefore closely connected with the industrial coal and steel economy of western Germany. After acquiring a roughly 300-kilometre pipeline system from RWE in 1928, it adopted the Ruhrgas name and expanded its role as an interregional gas transporter and supplier. During the 1930s, Ruhrgas built a substantial transmission network and supplied cities including Cologne, Düsseldorf, Hanover, and Saarbrücken. It also delivered gas to industrial customers, including the Adam Opel works. By 1936, its network extended for more than 1,100 kilometres and it was moving coal gas from dozens of coking plants. Natural gas discovered near Bad Bentheim in 1938 introduced a new long-term direction, although wartime conditions delayed the connection of the field to the company’s network until 1944. Much of the infrastructure was damaged during the Second World War, but the network was largely restored by the end of 1945. In the postwar period, Ruhrgas broadened both its technology base and its geographic reach. Together with Lurgi, it developed the Lurgi–Ruhrgas process for the low-temperature liquefaction of lignite and oil shale. It also began exporting coal gas to the Netherlands in cooperation with Thyssengas. As natural gas became increasingly important in European energy systems, Ruhrgas shifted from a predominantly coal-gas business toward long-distance natural-gas transmission, international procurement, storage, and wholesale supply. The company’s international importance grew sharply from the 1970s. In 1970, it concluded its first major contract to import Soviet natural gas, with the arrangement linked to deliveries of West German steel pipe to the Soviet Union. Further agreements connected Ruhrgas with gas supplies from Norway’s Ekofisk and Statfjord fields. The company also participated in infrastructure serving Switzerland, West Berlin, France, and southern Germany. Its partnership with Gaz de France on the MEGAL pipeline helped establish a major east-west corridor for Russian gas. By the late 1990s, Ruhrgas operated more than 10,000 kilometres of pipeline, compressor stations, and underground storage facilities, and sold more than 50 billion cubic metres of gas. E.ON acquired Ruhrgas in March 2003. The business was renamed E.ON Ruhrgas in July 2004 and became a central component of E.ON’s European gas strategy. During this period it held a 6.5% stake in Gazprom, later exchanged for an interest in Severneftegazprom, and expanded through investments in projects such as Nord Stream 1 and the Trans Adriatic Pipeline. E.ON Ruhrgas also acquired a majority stake in Romania’s DistriGaz Nord, which was renamed E.ON Gaz România. European energy-market liberalisation led to a structural separation of activities. In September 2010, E.ON Ruhrgas’s gas transportation and storage operations were transferred to E.ON Gastransport, later renamed Open Grid Europe. E.ON Ruhrgas itself ceased to exist as a standalone legal entity on 2 May 2013, when it was merged into E.ON Global Commodities SE. That business subsequently became part of Uniper. The Ruhrgas name survives in the corporate name Uniper Ruhrgas International GmbH, which reflects the continuing legacy of the former company’s international activities rather than an independent Ruhrgas operating group.

Ruhrgas was established in 1926 as Aktiengesellschaft für Kohleverwertung by Vereinigte Stahlwerke AG and Zeche Mathias Stinnes. Its initial purpose was to transport and market coal gas from coking plants in the Ruhr district, then one of Europe’s leading industrial regions. In 1928, the company acquired a pipeline network from RWE and changed its name to Ruhrgas AG. It expanded supply contracts with major German cities and industrial consumers, reaching more than 850 kilometres of pipeline by 1930 and over 1,100 kilometres by 1936. The discovery of natural gas near Bad Bentheim in 1938 created an opportunity to diversify beyond coal gas. A connection to the existing network was delayed by the Second World War, and a pipeline to the Hüls chemical works was completed only in 1944. Wartime damage affected much of Ruhrgas’s infrastructure, but approximately 90% of the network had been restored by the end of 1945. During the 1940s, Ruhrgas and Lurgi also developed a low-temperature process for liquefying lignite and oil shale, known as the Lurgi–Ruhrgas process. After the war, Ruhrgas resumed expansion. In 1948, it began exporting coal gas to the Netherlands with Thyssengas. Over subsequent decades, the company increasingly transitioned from coal gas toward natural gas transmission and wholesale supply. By 1965, its network had reached approximately 3,400 kilometres and its annual gas sales were reported at 3.3 billion cubic metres. International procurement became central to the company’s strategy in the 1970s. Ruhrgas signed its first major Soviet gas import contract in 1970. The arrangement was connected to a large order for steel pipe from West German manufacturers and was supported by substantial bank financing. Ruhrgas began supplying Switzerland in 1971 through the Trans Europa Naturgas Pipeline. It entered Norwegian supply arrangements for the Ekofisk field in 1973, with deliveries beginning in 1977, and also developed routes for Soviet gas reaching West Berlin through East Germany. In 1975, Ruhrgas and Gaz de France created the partnership responsible for the MEGAL pipeline, which entered service in 1980 and transported Russian gas toward France and southern Germany. Ruhrgas later supported construction of the Urengoy–Pomary–Uzhhorod pipeline and joined a consortium importing gas from the Statfjord field. Statfjord deliveries began after the Statpipe system was commissioned in 1985. These projects made Ruhrgas a major intermediary between gas-producing regions and European markets. By 1998, Ruhrgas operated more than 10,000 kilometres of pipeline, 26 compressor stations, and 12 underground storage facilities, while annual sales exceeded 50 billion cubic metres. In 1999, it contributed to the restoration of the Amber Room at the Catherine Palace near Saint Petersburg. Before its acquisition, the company was held through several German industrial and energy-sector holding structures, with Bergemann GmbH as the largest shareholder. E.ON acquired Ruhrgas in March 2003 and renamed it E.ON Ruhrgas in July 2004. The company became an important part of E.ON’s European gas portfolio. It held a 6.5% stake in Gazprom until that interest was repurchased in 2009 under an asset-swap arrangement. In exchange, E.ON Ruhrgas obtained a stake in Severneftegazprom, the operator of the Yuzhno-Russkoye field. E.ON Ruhrgas also acquired 51% of Romania’s DistriGaz Nord in 2005, joined the Nord Stream 1 project, and acquired a 15% interest in the Trans Adriatic Pipeline in 2010. Regulatory unbundling changed the company’s structure. On 1 September 2010, its gas transportation and storage operations were transferred to E.ON Gastransport, later renamed Open Grid Europe. E.ON Ruhrgas was finally merged into E.ON Global Commodities SE on 2 May 2013. That business later became part of Uniper. The Ruhrgas name remains in Uniper Ruhrgas International GmbH, a company connected with the former group’s international activities.

  Natural gas transmission

  Ruhrgas operated a large high-pressure pipeline network connecting domestic production, imported gas, storage facilities, utilities, industrial customers, and cross-border markets. Transmission became the company’s central activity as European gas consumption shifted away from coal gas and toward natural gas. Natural gas was the company’s principal commodity. Ruhrgas purchased gas from domestic and international producers, including Soviet and Norwegian sources, and supplied utilities, municipalities, industrial users, and other energy companies. Ruhrgas developed and operated long-distance pipelines, compressor stations, and cross-border connections. Its transmission network linked production areas, import routes, storage facilities, and German customer markets before the regulated network business was separated in 2010.

  Gas storage

  Ruhrgas owned and operated underground gas storage facilities that supported seasonal balancing and supply security. These assets were separated from E.ON Ruhrgas in 2010 as part of European regulatory unbundling.
