Hydrogen Storage
FromGravitricity Ltd
Our underground hydrogen storage technology uses the geology of the earth to safely store large volumes of green hydrogen. Purpose-built shafts can be built wherever required to offer long-term storage close to the point of demand. Storing hydrogen in underground shafts is intrinsically safer and less obtrusive than above-ground options and is a solution that does not require unique geology such as salt caverns. Safe, Flexible capacity, Lower costs, Location flexibility.

- Storing hydrogen underground reduces the risk of leaks and protects storage container from damage
- We can store up to 100 tonnes of compressed hydrogen per shaft, with option to have multiple shafts on one site
- Surrounding geology helps contain pressure and reduces storage costs
- No need for specific geological conditions, can store hydrogen where it is needed
Gravitricity’s hydrogen storage technology is ideally placed to meet the growing demand for green hydrogen in the following use cases:
- Existing uses. Hydrogen production by electrolysis will replace existing carbon emitting production techniques for applications such as ammonia and methanol production.
- High grade heat. Hydrogen is the only low carbon way of reaching temperatures needed in numerous industrial processes, including steel making.
- Grid scale energy storage. Electrolysis of water can generate hydrogen from otherwise curtailed renewable generation, providing GW scale storage for daily peaks, long duration and inter-seasonal requirements.
- Shipping and aviation. The growing requirements of shipping and aviation will drive the growth of green hydrogen production and the need for storage facilities at ports and airports.
