Underground Hydrogen Storage Market To Reach 6,249.05 MCM By 2033

Underground Hydrogen Storage Market Growth & Trends

The global underground hydrogen storage market demand is estimated to reach 6,249.05 MCM by 2033, registering a CAGR of 9.2% from 2025 to 2033, according to a new report by Grand View Research, Inc. The underground hydrogen storage market is projected to observe significant growth over the estimated period owing to an increase in hydrogen production and a lack of viable alternatives for large-scale hydrogen storage. Underground hydrogen storage is currently the only viable large-scale storage technology for hydrogen due to its ability to safely store large quantities of hydrogen in a compact and secure location. One of the main advantages of underground storage is that it is much safer than above-ground storage as hydrogen has a very low flash point and is highly flammable. Underground storage eliminates the risk of accidents or leaks as the hydrogen is stored deep below the ground in a sealed container. This also means that there is no risk of damage to the surrounding environment or infrastructure in the event of an accident.

Salt caverns dominated the type segment in 2024 and this segment is expected to maintain its position over the forecast period. Salt caverns are developed from existing salt reserves. Underground salt caverns are considered the best option for bulk hydrogen storage due to their structural strength, which makes caverns capable enough against degradation to ensure the long life of the storage facility.

Demand for underground hydrogen storage is projected to rise over the forecast period owing to the increasing demand for hydrogen and programs to cut carbon emissions. The increasing investments in research and development for underground hydrogen storage in regions like North America, the Middle East & North Africa, and the Asia Pacific are expected to strengthen market growth.

Underground Hydrogen Storage Market Report Highlights

• In terms of volume, the salt caverns segment accounted for the largest share of 97.66% in 2024 and this segment is further expected to witness steady growth over the forecast period.

• In 2024, Europe accounted for the largest volume share of 58.52% in 2024. Lower building and operational costs coupled with higher safety offered by salt caverns are expected to result in the growth of the salt caverns storage segment in the underground hydrogen storage market in regional economies.

• Various strategic initiatives have been recorded over the past few years to boost the growth of the market. For instance, in March 2025, Air Liquide announced a partnership with a European energy consortium to develop one of the continent’s largest underground hydrogen storage facilities in a salt cavern located in northern Germany.
