Key Takeaways
- Airengy (TASE: ARNG) signed a partnership agreement with Nobian to explore compressed air energy storage in a Nobian-operated salt cavern in Denmark with a capacity of 2.5 GWh and an output of 3–10 megawatts.
- The collaboration will evaluate Airengy's AirBattery technology, with Nobian handling the cavern's regulatory, permitting and infrastructure work while remaining the license holder and operator.
- This is Airengy's fourth European power-plant partnership, following prior agreements in England (KISTOS), Romania (Hagag Europe) and Germany (SEFE).
- The project is part of a two-phase strategy Airengy published in December, pairing smaller 1–1.5 MW plants in Romania and England with large-scale developments in Romania and now Denmark.
- Airengy CEO Tal Raz said the company is also exploring expansion into data-center energy demand alongside its grid-storage projects.
Airengy Signs Fourth European Partnership With Nobian
Airengy (TASE: ARNG) announced a new partnership agreement to explore and assess the potential of long-duration compressed air energy storage in a Nobian-operated salt cavern in Denmark. The site has a capacity of 2.5 gigawatt-hours (2,500 megawatt-hours) and an output in the range of 3 to 10 megawatts. The planned power plant would connect to an existing salt cavern operated by Nobian, a European leader in high-purity salt, low-carbon essential chemicals and underground energy storage caverns. The collaboration will focus on evaluating Airengy's AirBattery technology.
How the Denmark Project Will Work
Under the agreement, Nobian will handle the work tied to the salt cavern, including regulatory and permitting processes, stakeholder management and related infrastructure, while remaining the license holder and operator. Airengy will handle the AirBattery system design, air compression and electricity generation using its proprietary technology, targeting an energy generation capacity of approximately 2.5 gigawatt-hours connected to the existing cavern.
Part of a Broader European Strategy
This is Airengy's fourth power-plant partnership across Europe, following agreements in England with KISTOS, Romania with Hagag Europe, and Germany with SEFE. The company said the Nobian agreement completes its strategy of establishing operations across its key target markets, and fits within the two-phase strategy Airengy published in December, which pairs smaller 1-to-1.5-megawatt plants in Romania and England with large-scale developments in Romania and now Denmark.
Airengy and Nobian Leaders on the Agreement
“At Nobian, we see large-scale energy storage as a critical building block of a reliable and affordable renewable energy system. By exploring the combination of our salt cavern expertise with Airengy's innovative technology, we aim to unlock new ways to store and release energy over longer periods, helping to reduce grid congestion,” said Louwrens op de Beek, Director Energy Storage at Nobian.
“The agreement with Nobian continues and advances our deployment into our European target markets and proves the company's implementation capabilities,” said Maj. Gen. (res.) Yiftah Ron-Tal, Chairman of Airengy. “The collaboration connects Airengy's energy-storage technology with existing geological infrastructure and industry know-how and demonstrates our ability to create partnerships with leading companies in strategic markets.”
“The agreement with Nobian marks another significant milestone in Airengy's development,” said Tal Raz, CEO of Airengy. “Nobian's decision to collaborate with Airengy constitutes a strong expression of confidence in the technology we have developed and in our ability to lead large-scale commercial projects.”
Raz added that, alongside its grid-storage projects, Airengy is also exploring an expansion into the data-center energy market, which it expects to become a major source of demand for energy infrastructure over the next decade.
