Grid-scale, subsurface pumped hydropower storage
Long-duration energy storage allows renewables to scale.
Advanced but proven oilfield infrastructure without the environmental tradeoffs of traditional systems.
Our mission is to provide reliable, zero-emission renewable power by storing excess energy using subsurface reservoirs and delivering it to the grid when it needs it most.
SPHS improves on proven technology.
Subsurface Pumped Hydropower Storage (SPHS) takes the best attributes of traditional Pumped Hydro Energy Storage (PHES), which represents over 90% of global energy storage, and makes it better:
-
Utilizes proven, cost efficient oilfield drilling and completion services.
-
SPHS does not require a surface elevation change.
-
Smaller footprint means less damage to ecosystems
-
Reduced ecosystem impact and underground infrastructure reduces stakeholder opposition.
-
Applicable to all mature oil and gas basins globally. Scalable to 100s of MW of generation capacity and 1000s of MWh of energy storage
-
Unlike PHES, SPHS does not require fresh water.
-
Quiet, low surface pressure operation
