The study also included a techno-economic evaluation of a 200 MWh commercial-scale demonstration. The projected size of the system will be up to 4 MWe with at least 4 hours of storage duration, or 16 MWh-e total. Zeltmann Power Project (Zeltmann) NGCC plant in Astoria, New York.

For the feasibility study, the Brenmiller technology was designed to operate on a slipstream from NYPA’s Eugene W. For this application, the estimated efficiency is 80% thermal to thermal.

The crushed rock storage technology, which is being developed by Brenmiller Energy, is a more » modular TES system termed bGen™, which can accommodate both thermal and electrical inputs and output steam, hot water, or hot air. The completed effort included a feasibility study to prepare for the Phase II pre-front end engineering design (pre-FEED) for implementing a crushed-rock TES system integrated with a natural gas combined cycle (NGCC) plant. Thermal energy storage (TES) represents an ideal technology for this purpose.

The goal of this project was to design a next-step pilot to advance near-term energy storage integrated with a fossil plant to provide a facility capable of being viable and effective in a market with growing penetration of variable renewable energy (VRE).
