Learn MoreUnderground Sun Storage (Austria) - Underground Sun Storage is a pilot project for storing hydrogen in depleted gas reservoirs. The stored gas is a mixture of natural gas (90%) and green hydrogen (10%).
The project demonstrated that it is possible to store renewable energy in the form of hydrogen in underground porous media. Hydrogen did not have any negative influence on the integrity of the reservoir and cap rock. The project studied the complete life cycle of hydrogen injection, storage and recovery.
There are mainly three potential types of underground hydrogen storage in scale above GWh. The first option is salt caverns which is a proven technology for storing hydrocarbons, including natural gas, liquefied hydrocarbons such as LPG, crude oil or refined products. The worldwide count of salt caverns surpasses 1900.
Recent economic analysis suggests that demand from the power industry, transport (hydrogen fuel cells), and hydrogen-consuming industries will drive the economics of underground hydrogen storage in the future. The economic analysis of different hydrogen storage can be significantly site (location) dependant.
Potentials, technical challenges, and economics of underground hydrogen storage are investigated. The UK's future needs for storing hydrogen in both salt caverns and porous media are evaluated. The UK's potential storage options are ranked. The significance of repurposing the existing underground gas storage facilities is highlighted.
Economics of underground hydrogen storage Underground geologic storage of hydrogen not only offers substantial cost reductions and buffer capacity to address disruptions in supply or seasonal demands but also presents a sizable financial asset, ensures continuity of delivery, and helps control congestion in the pipeline system .
