Gem hydrogen energy storage

Where can hydrogen and natural gas be stored?

There have been several successful hydrogen and natural gas or hydrogen and CO 2 mixture storage projects, including Ketzin in Germany, Beynes in France, and Lobodice in the Czech Republic [21, 22]. A generic scheme of underground hydrogen storage in an aquifer coupled with cushion gas support is presented in see Fig. 1.

Is hydrogen geologic storage a viable energy source in China?

Hydrogen, as a clean and efficient energy source, is important in achieving zero-CO 2 targets. This paper explores the potential of hydrogen geologic storage (HGS) in China for large-scale energy storage, crucial for stabilizing intermittent renewable energy sources and managing peak demand.

How effective is hydrogen storage?

The efficacy of hydrogen storage is largely influenced by the type of cushion gas employed, with CH 4 and N 2 being identified as the most effective due to their lower density contrast with hydrogen gas [39, 44].

Does CMG-gem improve hydrogen storage efficiency in a North Sea aquifer?

Compositional numerical simulation of underground hydrogen storage in a North Sea aquifer utilising CMG-GEM. Hydrogen recovery efficiency improves with the utilisation of cushion gas. CO 2 exhibits highest storage capacity; N 2 and CH 4 improve recovery efficiency.

Does cushion gas density affect Underground hydrogen storage efficiency?

Cushion gas density dictates the efficiency of the underground hydrogen storage scheme. This study investigated the impact of cushion gas type and presence on the performance of underground hydrogen storage (UHS) in an offshore North Sea aquifer.

Can hydrogen be stored in aquifers?

One promising option for hydrogen storage is in aquifers that offer the potential for large-scale, long-term storage solutions [, , ]. There have been several successful hydrogen and natural gas or hydrogen and CO 2 mixture storage projects, including Ketzin in Germany, Beynes in France, and Lobodice in the Czech Republic [21, 22].
