Our flexible storage technology is applicable to multiple areas in energy and powergrid systems.

SCALABLE Storage system can be scaled up or down to fit specific energy system requirements DURABLE Extremely long lifecycle since concrete withstands millions of stress cycles STORAGE DURATION Best suited for medium to long storage purposes (i.e. 3 hours to various hours) ECONOMICAL Low cost materials (i.e. steel and HEATCRETE®) ensure extreme cost competitiveness LEGO-LIKE CONCEPT With pre-fabricated elements with high degree of standar- dization; easy to integrate into energy systems EASY TO INSTALL Modules installation in assembly line approach; materials and components are easy to localize SAFETY Solid state non-hazardous material; no HSE requirement beyond power plant specs. CONFIGURABLE Caters to broad temperature range (-50 – 565°C); operating with different HTFs LOW O&M No moving parts, easy to control, almost no parasitic loads, no special staff requirements SMART DESIGN EASE OF INSTALLATION EASE OF OPERATION


Masdar Pilot

Masdar Institute of Science and Technology and EnergyNest initiated a comprehensive joint research project in 2013 for building and testing a 2 x 500 kWhth Thermal Energy Storage (TES) pilot. The pilot facility is now fully operational and has been validated by DNV GL with regards to operating temperature, energy storage capacity, and energy efficiency. The project demonstrates the feasibility and advantages of EnergyNest’s storage system, generating key operational and performance data that can be shared upon request.
