Hydrogen energy storage slovakia

Should Slovakia use hydrogen as energy carrier?

In its National Hydrogen Strategy (NHS), the Slovak government advocates for using hydrogen as an energy carrier in all its industrial branches and in public life where it is not possible to use electricity directly. The NHS creates a coherent framework for this use.

Where is hydrogen storage feasible?

Hydrogen storage is feasible in aboveground infrastructures as well as in underground constructions. Proper geological environments for underground hydrogen storage are porous media and rock cavities.

Why is hydrogen storage important?

“Hydrogen storage plays an essential role in achieving successful hydrogen economy. Our long-term storage experience and our strategic location allows us to substantially contribute to the cooperation in the area of hydrogen and CO2 storage.

Which geological environment is best for Underground hydrogen storage?

Proper geological environments for underground hydrogen storage are porous media and rock cavities. Porous media are separated in depleted hydrocarbon reservoirs and aquifers, while rock cavities are subdivided into hard rock caverns, salt caverns, and abandoned mines.

Is cavern mining a viable option for hydrogen storage in aquifers?

Despite the lack of detailed estimations for hydrogen storage in aquifers and based on the capital cost required for the main infrastructure, this option is characterised as another economic technology. When cavern mining is a required step for the final hydrogen storage, the cost increases.
