The system can discharge at this power for three and a half days, of 84 hours, which equates to a potential 26,880MWh or 26.88GWh energy storage capacity. Utility Eneco and Corre Energy have signed an agreement for the latter to deploy a 320MW, 84-hour duration compressed air energy storage system (CAES) in Groningen, the Netherlands.
Exploratory drilling will start in 2023 to assess if the site is suitable for compressed air storage, and the installation of the entire system is expected to be completed by 2026. The planned system will use up to 220MW of power to convert excess electricity into compressed air and store it in the cavern.
Cavern construction is already underway, with handover of the first two expected in early 2027. Phase one of the Ahaus project will use two of the site’s existing salt caverns to deploy Corre Energy’s multiday CAES solution to deliver 220 MW of compression capacity and 320 MW of generation capacity.
The VECTES (Vantaa Energy Cavern Thermal Energy Storage) is a seasonal energy storage project, which enables harnessing the warmth of summer for the cold winter days. The facility will be the world''s largest cavern thermal energy storage with 1,000,000 m3 in size. ... such as waste heat from air conditioners, solar and geothermal.

Focusing on salt cavern compressed air energy storage technology, this paper provides a deep analysis of large-diameter drilling and completion, solution mining and morphology control, and evaluates the factors affecting cavern tightness and wellbore integrity. The future development and challenges of underground salt caverns for compressed air ...
Energy storage is essential for the integration of renewables, as it can store energy when prices are low and supply is high, and release this energy when prices are high and supply is limited. Different technologies, such as batteries and pumped storage, are used for energy storage at different scales. Energy storage improves the reliability and resilience of the energy system, …
Compressed air energy storage systems may be efficient in storing unused energy, but large-scale applications have greater heat losses because the compression of air creates heat, meaning expansion is used to ensure the heat is removed [[46], [47]]. Expansion entails a change in the shape of the material due to a change in temperature.
On September 23, Shandong Feicheng Salt Cave Advanced Compressed Air Energy Storage Peak-shaving Power Station made significant progress. The first phase of the 10MW demonstration power station passed the grid connection acceptance and was officially connected to the grid for power generation. This marked the world''s first salt cave advanced ...

Together with technology companies, research institutions, grid operators, and financiers, we are working towards a stable, independent, and sustainable energy supply. Energy Storage NL serves as the advocate, networker, and knowledge center for the Dutch energy ...
The heat from solar energy can be stored by sensible energy storage materials (i.e., thermal oil) [87] and thermochemical energy storage materials (i.e., CO 3 O 4 /CoO) [88] for heating the inlet air of turbines during the discharging cycle of LAES, while the heat from solar energy was directly utilized for heating air in the work of [89].
Compressed air energy storage (CAES) is one of the important means to solve the instability of power generation in renewable energy systems. To further improve the output power of the CAES system and the stability of the double-chamber liquid piston expansion module (LPEM) a new CAES coupled with liquid piston energy storage and release (LPSR-CAES) is proposed.
Compressed air energy storage (CAES) is a large-scale energy storage technique that has become more popular in recent years. It entails the use of superfluous energy to drive compressors to compress air and store in underground storage and then pumping the compressed air out of underground storage to turbines for power generation when needed …
