GeoVolt is harnessing the Earth’s subsurface for ultra-long duration energy storage, enabling a clean, reliable, and scalable energy system that supports the transition to net zero.
Increasing penetration of intermittent, renewable sources of power generation poses problems for the grid. Weather systems do not match power demands leading to imbalances in the system.
Renewable power generation is quickly becoming the cheapest source of electricity, and with increased adoption of EV's, heat pumps and AI, these power sources will become even more prevalent.
Energy storage is needed alongside renewables to balance periods of high and low supply. Batteries are excellent for short durations (<8 hours) but are expensive to scale beyond that.
Compressed air energy storage is an established technology deployed globally since the 1990's. With our expertise in developing and engineering subsurface porous media, GeoVolt is applying CAES to end-of-life gas reservoirs, unlocking the next step in low cost, large scale, multi-day energy storage.
Natural subsurface systems are vast. Small to moderately sized reservoirs are easily capable of storing over 100GWh of clean power. Larger systems can reach 10s TWh.
The scale of subsurface systems allows for multi-day to seasonal timeframe power storage, focusing on the next step in the long duration energy storage problem.
Subsurface reservoirs provide the lowest marginal cost of storage of any emerging LDES technology given its natural size and scale.
CAES utilises conventional rotating equipment to compress and expand air providing inertia and synchronicity to support grid stability.
Existing, old, depleted gas reservoirs provide the ideal deployment setting, giving a new lease of life to assets and offsetting decommissioning costs.
GeoVolt's solution removes dependency on global fuel imports and prices, improves energy security and provides new opportunities for the oil & gas industry.
