Can energy storage be combined with hydrogen?

In this paper, an innovative concept of an energy storage system 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.

What type of energy storage system does a hydrogen generator use?

The first is a typical Power-to-H2-to-Power system, which integrates hydrogen generators with a fuel cell system. The other two additionally use a compressed air energy storage installation. In the first case the compressed air energy storage system consists of a diabatic system.

What is compressed hydrogen?

Compressed hydrogen is a storage form whereby hydrogen gas is kept under pressure to increase the storage density. It is the most widely used hydrogen storage option. It is based on a well-established technology that offers high rates of charge and discharge.

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.

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).
