Overview
Securing Energy for Europe, commonly known as SEFE, is a German energy company headquartered in Berlin. Its activities extend across the natural-gas value chain, including sourcing, wholesale trading, sales, transportation and underground storage. Through group companies and investments, SEFE supplies industrial and other customers in Germany, the United Kingdom and additional European markets, while related entities operate in parts of Asia, Central Asia, Singapore and North America. The company is a major participant in the German and European gas system. Its sales businesses deliver roughly 200 terawatt-hours of gas and power annually and serve more than 50,000 customers in Germany and several other European countries. SEFE Storage operates facilities with aggregate capacity of approximately 7 billion cubic metres, equivalent to about one quarter of Germany's total gas-storage capacity. The Rehden site, with capacity of about 4 billion cubic metres, is Germany's largest individual gas-storage facility. Through WIGA, SEFE also controls major gas-transmission assets, including the Opal, Eugal and NEL pipeline systems, which together cover approximately 4,150 kilometres and connect Germany with five neighbouring countries. SEFE's history is closely tied to the restructuring of the European gas market and to the former Gazprom Germania group. From 1990 until 2022, the business operated as Gazprom Germania GmbH and was wholly owned by Gazprom. The company developed a network of gas sales, storage, trading and infrastructure businesses under the European regulatory framework. Its ownership and commercial relationships became politically sensitive as European governments examined Russian influence over strategic energy infrastructure and as gas-storage levels declined during the period preceding Russia's full-scale invasion of Ukraine. In April 2022, after Gazprom-related ownership changes and the deteriorating European energy-security situation, Germany's Federal Network Agency assumed trusteeship over the company. Russia subsequently imposed sanctions on Gazprom Germania and related businesses. The German government established a holding vehicle for a possible takeover and, in November 2022, transferred full ownership of the company to the German state with European Commission authorisation. The business was subsequently re-established under the SEFE identity, reflecting a strategic shift away from dependence on Russian gas and toward security of supply for Germany and Europe. Since nationalisation, SEFE has sought to diversify procurement through long-term arrangements with suppliers in the United States, Norway, Oman, the United Arab Emirates, Angola and elsewhere. Its portfolio includes pipeline gas and liquefied natural gas, and the company has expanded its role in LNG sourcing and marketing. SEFE has also pursued infrastructure and energy-transition opportunities. These include possible conversion of gas pipelines and storage facilities for clean hydrogen, participation in the proposed Flow hydrogen pipeline network, and a partnership concerning imports of green hydrogen from Brazil. The German government has indicated that the company is expected to be considered for privatisation by the end of 2028, although its ownership remains state-controlled.
History
Securing Energy for Europe developed from Gazprom Germania GmbH, a business established in 1990 and wholly owned by Gazprom until 2022. Under the Gazprom Germania name, the group built a broad European gas platform with activities in wholesale supply, trading, storage and pipeline infrastructure. Its commercial structure included entities such as WINGAS, later rebranded as SEFE Energy, and astora, later known as SEFE Storage. The group also held interests in gas infrastructure and companies operating in Central and Eastern European markets. The company's ownership structure became increasingly controversial as European governments assessed the role of Russian-controlled intermediaries in the liberalised European gas market. Concerns included the relationship between Gazprom and affiliated trading or infrastructure companies, the strategic importance of gas storage and pipelines, and the possibility that Russian state interests could influence European energy security. Low storage levels at certain Gazprom-associated facilities in early 2022 intensified those concerns. In late March 2022, Gazprom-related ownership changes left the German authorities concerned about control of a strategically significant energy business. In April, Germany's Federal Network Agency was appointed trustee of the company. The intervention took place shortly after Russia's invasion of Ukraine and amid a wider European effort to reduce dependence on Russian gas. Russia later imposed sanctions on Gazprom Germania and associated businesses, complicating the group's operations and procurement relationships. The German government prepared a holding structure for a possible nationalisation. The vehicle was initially created under an administrative name and was later renamed Securing Energy for Europe Holding GmbH. In November 2022, the Federal Ministry for Economic Affairs and Climate Action ordered the transfer of full ownership to the German state, with authorisation from the European Commission. The operating group subsequently adopted the SEFE name. After the takeover, SEFE's central strategic task became maintaining supply security while replacing or reducing Russian sourcing. The group expanded its LNG and international procurement activities and signed long-term arrangements with suppliers including Venture Global, Equinor, Oman LNG, ADNOC, ConocoPhillips and Angola LNG. These agreements complemented pipeline gas and supported access to alternative sources for German and European customers. SEFE has retained and expanded its role in gas infrastructure. Its storage arm operates facilities with total capacity of approximately 7 billion cubic metres, while WIGA operates the Opal, Eugal and NEL transmission systems. In 2024, SEFE moved to full ownership of WIGA by acquiring Wintershall Dea's 50.02 percent stake, subject to European regulatory approval. The company is also examining a longer-term transition beyond natural gas. Proposed initiatives include adapting sections of the gas network and underground storage system for hydrogen, participating in the planned Flow hydrogen corridor and developing international supply partnerships for green hydrogen. SEFE's state ownership is not necessarily permanent: the German government has indicated that privatisation is expected to be considered by the end of 2028. Until then, SEFE remains a government-owned energy company whose mandate combines commercial activity with national and European energy-security objectives.

Products and positioning
A strategically important German energy supplier and infrastructure operator focused on security of gas supply, diversification of procurement and gradual participation in the hydrogen economy.
Natural gas
Natural gas supply
SEFE supplies natural gas to industrial and other customers through its European sales organisations. The business combines imported pipeline gas, LNG and traded volumes, with procurement increasingly diversified across non-Russian suppliers. Its sales activities cover Germany, the United Kingdom and additional European markets.
Liquefied natural gas
LNG sourcing and marketing
SEFE sources and markets LNG as part of its post-2022 supply-diversification strategy. Long-term arrangements and supply discussions have involved suppliers in the United States, Oman, the United Arab Emirates and Angola, complementing pipeline gas and helping serve European demand.
Gas storage
SEFE Storage
SEFE Storage, formerly associated with astora, operates underground natural-gas storage facilities with total capacity of approximately 7 billion cubic metres. Its Rehden facility is Germany's largest storage site. The business provides capacity that supports seasonal balancing and wider gas-system security.
Energy infrastructure
