How CavernX
Works

From geological survey to first injection, our end-to-end process is engineered for speed, safety, and scalability.

01 //

Site Survey & Geology

We identify suitable halite formations using 3D seismic imaging, borehole analysis, and subsurface modelling to map viable cavern zones.

02 //

Solution Mining

Fresh water is injected to dissolve salt strata, creating precisely shaped underground caverns. Brine is safely extracted and processed.

03 //

Injection & Storage

Energy carriers — hydrogen, natural gas, or compressed air — are injected under pressure and stored in the impermeable salt cavern.

// Capabilities

Built for the
Energy Transition

Hydrogen-Ready Infrastructure

Cavern geometry and lining specifications designed to accommodate green hydrogen at scale, future-proofing every asset we build.

Geomechanical Safety Systems

Real-time subsurface monitoring, distributed fibre sensing, and automated pressure management protect cavern integrity 24/7.

Rapid Cycling Capability

Our cavern designs support multiple daily injection-withdrawal cycles, providing the fast-response storage that grid operators need.

Portfolio-Scale Analytics

Our proprietary CAVOS platform models dispatch optimisation, arbitrage revenue stacks, and long-term reservoir behaviour across site portfolios.

Low Surface Footprint

Minimal above-ground infrastructure. Underground storage preserves land-use value and reduces planning complexity versus surface battery alternatives.

Full EPC & O&M Delivery

From feasibility through construction to long-term operations, CavernX provides integrated project delivery with single-point accountability.
