What is Zero Terrain?
Zero Terrain is revolutionizing the way renewable energy is stored and delivered. It removes obstructions from affordable local renewable energy and creates a secure, clean future for generations to come. Unlike traditional pumped hydro storage that depends on natural altitude differences, Zero Terrain’s breakthrough technology stores energy underground, requiring zero terrain elevation. This means no mountains, just a flat surface with massive underground storage capacity. It’s a complete energy system overhaul designed to provide 100% renewable, affordable, and secure energy with minimal environmental impact. Simply put, it’s the future of energy storage—unobstructed and ready to power a cleaner, brighter world.
Main Benefits and Key Facts
Zero Terrain offers a range of impressive benefits that make it a game changer in the energy sector. Here are some key figures and facts that highlight its potential:
- Energy Capacity: 0 MW (planned scale to reach 500 MW with Energiasalv)
- Underground Storage Depth: 0 meters (with plans for extensive underground reservoirs)
- Gneiss Usage: 0 metric tons (leveraging durable, eco-friendly rock for construction)
- Full Power Generation Hours: 0 hours (designed for continuous, reliable output)
- Renewable Energy Percentage: 0% (targeting 100% renewable energy supply)
These numbers might look like zeros now, but they represent the starting point of a massive shift toward affordable, clean, and secure energy storage solutions.
Technology Behind Zero Terrain
Pumped-hydro energy storage plants are widely recognized as the most favorable large-scale storage technology. They help balance power systems and enable the transition from fossil-based economies to renewable-based ones. Zero Terrain takes this concept further by creating the necessary height variance underground, eliminating the need for natural terrain elevation. This innovation drastically reduces the above-ground footprint, preserving landscapes and minimizing ecological disruption. The technology is designed to store excess renewable energy—like wind and solar—by pumping water into underground reservoirs, ready to be released when demand spikes. It’s a smart, scalable solution for today’s energy challenges.
Introducing Energiasalv: The Underground Battery
Energiasalv is a flagship project within the Zero Terrain vision—a 500 MW underground battery set to be built in Paldiski. When renewable energy production exceeds consumption, Energiasalv stores that surplus by pumping water from underground reservoirs into Paldiski Bay. This stored energy can then be released back into the grid when needed, ensuring a steady, reliable supply. It’s like having a giant, invisible battery beneath the surface, ready to power homes and industries without the environmental costs of traditional storage methods. This project exemplifies how Zero Terrain’s technology can be applied on a large scale to support the green transition.
Gneiss: The Sustainable Construction Material
Gneiss plays a crucial role in the Zero Terrain infrastructure. Compared to limestone, gneiss offers superior durability, lower long-term costs, and a significantly reduced environmental impact. This makes it a more sustainable and cost-effective alternative to commonly used construction materials like limestone and imported granite. Using gneiss not only strengthens the underground structures but also aligns with the project’s commitment to minimizing ecological footprints. It’s a smart choice that supports both the environment and the economy.

Latest Developments and Industry Recognition
Zero Terrain is gaining global attention. A recent report by hydropower specialist Mike McWilliams, titled “The Global Need for Underground Pumped Storage Hydro,” highlights the accelerating demand for this technology. Additionally, Zero Terrain is set to present its breakthrough energy storage infrastructure systems at the upcoming Unleashed conference in Stockholm. These developments underscore the growing recognition of underground pumped hydro storage as a cornerstone for the green transition. As the world moves toward electrification and renewable energy, Zero Terrain’s solutions are proving essential for securing reliable, scalable energy storage that supports a sustainable future.
