astora product offering

Product offering

Core offering

Astora, operating commercially as SEFE Storage GmbH, runs underground natural gas storage facilities at three sites — Jemgum (cavern storage), Rehden (natural reservoir "supertank"), and Haidach — and rents storage capacity to energy traders, gas suppliers, and industrial consumers through auction-based and customized capacity products allocated primarily via the PRISMA capacity platform, with additional services such as interruptible capacities, REMIT compliance reporting, and transfer services.

Product overview

SEFE Storage operates as one of Europe's largest natural gas storage operators, offering a unified portfolio of storage products and services. The core offering includes three major storage facilities: the flexible cavern storage at Jemgum, the natural 'super tank' at Rehden, and the optimally-conditioned facility at Haidach. The product suite spans standardized and auction-based capacity products (Auktionsprodukte, Standardprodukte, Sonderprodukte), additional capacity services, interruptible services, REMIT compliance services, and transfer services. SEFE Storage has also begun developing hydrogen storage capabilities through its JemgumH2 project. All capacity allocation is managed through the PRISMA platform, with a customer portal for account management.

astora competitors and assessment

Company assessment

Direct peers

Uniper Energy Storage: Uniper operates underground gas storage facilities in Germany (including Etzel) and other European markets. Comparable to SEFE Storage in operating cavern and depleted-reservoir storage, marketing capacity to traders and utilities through standardized European platforms.
Storengy: Subsidiary of ENGIE and historically the largest natural gas storage operator in Europe, operating salt cavern and aquifer storage across France, Germany, and the UK. Direct competitor to SEFE Storage with comparable underground storage infrastructure and PRISMA-based capacity marketing.
VNG Gasspeicher GmbH: German underground gas storage operator owned by VNG/EnBW, operating storage assets in central Germany. Direct competitor to SEFE Storage in the German market with similar product offerings, auction-based capacity allocation, and PRISMA distribution.
NAFTA a.s. Slovak operator of underground gas storage facilities with strong presence in Central Europe, including Austria. SEFE Storage's Haidach operation places the two operators in overlapping Central European geography, competing for capacity demand from the same regional market participants.
RWE Gas Storage / Ineos Energy Storage: European gas storage assets formerly under RWE and now partly operated by Ineos, located in Germany/Czech Republic. Competes with SEFE Storage in the same German and Central European gas storage markets with comparable cavern storage technology.

Broad incumbents

Fluxys: Belgian gas infrastructure operator with storage assets (Loenhout) as part of a broader transmission and LNG terminal portfolio. Operates in the same European gas storage market as SEFE Storage, including PRISMA-linked capacity marketing, although fluxys's primary identity is broader infrastructure.
Snam: Italian gas infrastructure operator with gas storage among its regulated activities, comparable in business model (regulated gas infrastructure, capacity auctions, third-party access) but with a broader focus on transmission and storage across Italy.
E.ON Gas Storage: Gas storage operation embedded within E.ON's broader European utility and infrastructure portfolio. Comparable to SEFE Storage in underground storage operating model and PRISMA access, though E.ON is a multi-line utility rather than a pure-play storage operator.
