Comparison of pumped hydro, hydrogen storage and compressed air energy
In this case, the reductions in LEC of pumped hydro and compressed air storage are only 10% and 20% respectively, and for hydrogen storage it is 70%. As a result, hydrogen storage overtakes pumped hydro. On the basis of the assumptions made for 2030, both compressed air and hydrogen storage are more favorable than pumped hydro.

Can energy storage be combined with hydrogen?
In this paper, an innovative concept of an that combines the idea of energy storage, through the use of compressed air, and the idea of energy storage, through the use of hydrogen (with its further conversion to synthetic natural gas), has been proposed.
How much energy does a hydrogen energy storage system use?
Flow diagram for the hydrogen energy storage system. For the two-stage compressed air energy storage system, the specific energy consumption of the compressors and the turbines is 0.1613 kWh/kg air and 18.85 kg air/kWh respectively.
How do compressed air storage systems use energy?
The modeled compressed air storage systems use both electrical energy (to compress air and possibly to generate hydrogen) and heating energy provided by natural gas (only conventional CAES). We use three metrics to compare their energy use: heat rate, work ratio, and roundtrip exergy efficiency (storage efficiency).
How is hydrogen stored?
The generated hydrogen is stored to burn and heat the air during the discharge phase. We choose not to consider any physical storage of heat, similar to conventional CAES and in contrast to A-CAES. This is due to the relatively low temperature of air upon giving its heat to the HTE system.
What is a conventional compressed air energy storage system?
Schematic of a generic conventional compressed air energy storage (CAES) system. The prospects for the conventional CAES technology are poor in low-carbon grids [2,6–8]. Fossil fuel (typically natural gas) combustion is needed to provide heat to prevent freezing of the moisture present in the expanding air .
Are two-stage CAES more efficient than a hydrogen storage system?
The comparison of the two-stage CAES without preheating, the single-stage with air preheating and the hydrogen energy system with respect to their efficiency and financial viability suggested that the two-stage system is by 2.5% more efficient compared to the hydrogen storage system.
