Airengy is partnering with Nobian, a European leader in high-purity salt, low-carbon essential chemicals and underground energy storage caverns. The companies will explore and assess the potential and feasibility of long-duration compressed air energy storage in Nobian’s salt cavern in Denmark with a capacity of 2.5 GWh (2,500 megawatt-hours) and an output in the range of 3-10 megawatts. The collaboration will focus on evaluating Airengy's AirBattery technology.

This is the fourth power-plant partnership across Europe announced by Airengy, following the plants in England (in partnership with KISTOS), Romania (in partnership with Hagag Europe) and Germany (in partnership with SEFE). The new agreement completes the company's strategy of establishing operations throughout its key target markets.
Under the agreement, Nobian will be responsible for performing the works relating to the salt cavern, including regulatory and permitting processes, local communication, stakeholder management and the related infrastructure, and it will remain the license holder and the operator of the cavern. Airengy will be responsible for the AirBattery system design, air compression and electricity generation using the proprietary technology it developed. The project is aimed at developing an energy generation capacity potential of approximately 2.5 gigawatt-hours using Airengy's compressed air technology connected to an existing cavern.
“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,” said Louwrens op de Beek, Director Energy Storage, Nobian.
“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,” said Tal Raz, CEO, Airengy.
