Zero Terrain
Zero Terrain is a geotechnical pumped hydro storage solution that allows to store energy like never before.
Pumped-hydro energy storage plants are the most mature and favorable large-scale storage technology, which helps balancing the power system and enables to switch from fossil-based economy to renewable-based economy. The challenge however is the need of mountains which significantly limits suitable locations.
Zero Terrain pumped-hydro storage technology can be used in regions which traditionally lack environmental prerequisites for hydro power projects, e.g. mountains or big rivers. The technological novelty of Zero Terrain Storage Solution is the placement of the lower reservoirs of the pumped storage plants in the Earth’s crust with favorable geology and using the surface water bodies as the upper reservoirs of the plants.
By placing the lower reservoirs in a suitable location on the Earth’s crust, additional income from sales of excavated rock is obtained. In case of the Estonian Pumped-Hydro Energy Storage project, the business plan involves production and sales of 15 million tonnes of chrystalline aggregates, which is to replace an imported high-cost igneous aggregates and low-quality domestic limestone aggregates, where appropriate.

About
Zero Terrain
THIS COMPANY OFFERS SOLUTIONS FOR
The decarbonization of the energy sector has 3 global challenges: affordability, environmental sustainability of solutions, and security of supply. With Zero Terrain, an unique energy storage solution, we are ready to face these challenges.
The conventional pumped-hydro has been considered the most competitive storage solution with robust and mature technology. It has high conversion efficiency and long useful life. We decided to take it one step further. Zero Terrain is an improved pumped-hydro solution, which has several advantages:
• First of all, while conventional pumped-hydro operates in the mountains, Zerro Terrain makes storing energy possible also in flat areas – yes, we build the energy storage underground.
• Secondly, its’ multiple revenue streams improve the feasibility of the storage. Zerro Terrain solution gives us opportunity to build synergy by sector coupling, developing several businesses at the same infrastructure, be it food production, extraction of mineral resources or building shelters.
Zero Terrain’s big advantage in terms of security of supply compared to other storage systems is its modular design, which allows the storage capacity to be increased at lower costs than any available alternative.
Zero Terrain’s underground storage solution has a lower environmental footprint than other storage technologies and uses less critical minerals. Effects on land use, fish stocks and water regime, which are known negative environmental impacts of conventional pumped-hydro, are minimized with our solution.
Zero Terrain’s 500MW 6 GWh demo project in Paldiski, Estonia is at the stage of receiving a building permit, construction is planned to start in 2023. We have begun the preparation of other projects implementing the Zero Terrain concept in different parts of the world, and we are looking for interested partners and investors to join us in this development consortium.
Store energy like never before with Zero Terrain, providing affordable energy and enhancing energy security with no harm to the environment. Join our Consortium!
