Technology
Technology as an enabler of bankable energy projects
Zero Terrain begins with the energy need and then develops the right technical solution based on the electricity system, available sites and assets, geology, water, grid access, permitting and commercial reality.
WHAT WE DO
Pumped Hydro Storage
Utility-scale pumped hydro with upper and underground lower reservoirs for long-duration energy storage.
Underground PHS
Underground lower reservoirs unlock new locations and significantly reduce surface footprint constraints.
Hydropower Conversion
Repurposing existing hydropower assets into flexible storage and balancing resources.
Hybrid storage
Combining PHS with batteries and other technologies to optimize performance and economics.
Renewable & Industrial
Integration
Seamless integration with renewables and industrial loads to support clean energy and competitiveness.
The Zero Terrain underground concept
By placing the lower reservoir underground, we expand the range of viable pumped hydro locations. This approach reduces dependence on mountainaus terrain, enables proximity to demand and grid infrastructure, and minimizes surface footprint and environmental impact-while preserving the long-duration performance and efficiency of pumped hydro.
KEY BENEFITS OF OUR APPROACH
Long-duration flexibility
Location flexibility
Limited visible surface footprint
Long asset life
System services and reliability
Lower exposure to critical minerals
Local value creation
