Airengy has signed a new partnership agreement in Denmark to explore and assess long-duration compressed air energy storage in a Nobian-operated salt cavern with a potential capacity of 2.5 GWh (2,500 MWh) and an output in the range of 3-10 megawatts.
The planned power plant will connect to an existing 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 long?duration storage technology in this subsurface setting.
This marks Airengy’s fourth announced power-plant partnership in Europe, following projects in England (with KISTOS), Romania (with Hagag Europe) and Germany (with SEFE). With the Danish agreement, the company completes its strategy of establishing operations across its core target markets.
Under the partnership, Nobian will handle all work related to the salt cavern, including regulatory and permitting processes, local communication, stakeholder management and associated infrastructure, while remaining the license holder and operator of the cavern. Airengy will be responsible for the design of the AirBattery system, air compression and electricity generation, leveraging its proprietary compressed-air technology.
The project aims to unlock an energy generation potential of around 2.5 GWh using Airengy’s technology connected to the existing cavern, supporting long-duration storage that can balance renewable generation and grid needs.
It forms part of the two-phase strategy Airengy outlined in December; first, securing partnerships to build and design power plants with outputs of 1-1.5 megawatts in Romania and England, while in parallel advancing large-scale plants in Romania and, now, Denmark.
Leadership Comments
Louwrens op de Beek, Director Energy Storage at Nobian: “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. This collaboration fits perfectly with our Grow Greener Together strategy and our ambition to be a balancing partner in the energy system in Denmark.”
Maj. Gen. (res.) Yiftah Ron-Tal, Chairman of Airengy: “The agreement with Nobian continues and advances our deployment into our European target markets and proves the company’s implementation capabilities. 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. We intend to continue forming additional partnerships that will accelerate the company’s growth and strengthen its standing in the global storage market.”
Tal Raz, CEO of Airengy: “The agreement with Nobian marks another significant milestone in Airengy’s development. Nobian is a European leader in salt mining and production, low-carbon essential chemicals and underground energy storage caverns development, with decades of experience, strategic assets, and first-rate engineering capabilities. 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. This partnership strengthens Airengy’s ability to advance additional commercial projects and to become a leading player in long-duration energy-storage infrastructure in Europe.
In parallel with the continued development of compressed-air-based energy-storage systems for the electricity grid, Airengy is exploring an expansion of its operations into the data-centers field, which is expected to be one of the most significant growth engines in demand for energy infrastructure over the coming decade. We believe that the CAPP technology we have developed, combined with strategic partnerships such as Nobian, can serve as a basis for advanced energy solutions for this market too.
We believe the coming decade will be defined by the construction of new energy infrastructure for electricity grids, industry, and data centers. Our goal is to position Airengy as one of Europe’s leading companies in long-duration energy solutions for these markets.”
