Main types of above ground and subsurface energy storage

Zero Terrain

as an underground economic cluster

In the future, it will be possible to develop Zero Terrain projects not only as hydroelectric energy storage, but as an entire infrastructure that enables the interaction of several sectors and thus strengthens the competitiveness of companies. With the Zero Terrain infrastructure, data centres, underground farms, mines, shelters, gas or other liquid reservoirs and spaces for military purposes can be built underground at low cost.

What are the advantages of the 
Zero Terrain solution?
1 / New areas

Zero Terrain enables the usage of hydroelectric energy storage in areas, where it was impossible before

2 / Low impact on earth

Zero Terrain reduces use of building materials and the impact on land by using earth beams as the building structure.

3 / Efficiency

Zero Terrain allows for higher storage capacity at a lower cost than any existing alternative due to its modular design

4 / Environmentally friendly

Zero Terrain serves as a tool to reduce carbon emissions

5 / Adds up to renewables

Zero Terrain improves feasibility of wind and solar projects by increasing their capture price

Zero Terrain – developed in Estonia

The Zero Terrain solution was developed in Estonia, using the expertise of the world's leading engineering companies. Its leaders are experts with extensive experience in the energy sector and a team of top engineers.

Zero Terrain's first project "Energiasalv" is planned in Paldiski, Estonia. The project has been under development for 13 years, it has received a building permit, and construction is scheduled to start in 2024.
