Key Benefits
Cost Effective
The Rondo Heat Battery provides the lowest-cost heat available today.
Hot
The RHBs temperature is variable and controllable, providing heat for low-temperature loads as effectively as in 1,500°C applications.
Simple Integration
Seamlessly integrates with boilers, kilns, dryers, and more — meeting any industrial facility’s heat conditions in a compact footprint.
Minimal Maintenance
RHBs have high durability, require minimal annual downtime, are cheap to maintain, and have a 40+ year lifespan with unlimited cycles.
Safe
Without fire or thermal runaway concerns, Rondo’s unpressurized system is intrinsically safe to meet or exceed safety standards.

A single RHB300 eliminates as much carbon as 8,500+ electric vehicles (EVs).
The Rondo Heat Battery is a Zero-Carbon Heat & Power solution
The Ideal Heat Storage Solution
Compared to other electrification solutions for industrial heat and power, the Rondo Heat Battery thermal energy storage solution eliminates the need to make tradeoffs or compromises when choosing between sustainability, product efficiency, temperature requirements, and cost considerations.
The Rondo Heat Battery is the lowest-cost solution to meet and exceed the rigorous demands of your facility and sustainability goals, all while lowering the cost of power.

Unrelenting quality standards ensure our customers’ status as leaders, no matter their industry.
Steam for Processes or Power

Rondo Heat Battery can deliver dispatch-able saturated or superheated steam that matches existing infrastructure for drop in installation.

Rondo Heat Battery can directly deliver hot air at high temperatures, or a variety of other gas streams, to replace fossil fuels in direct -and indirect - fired processes.

Rondo Heat Battery can operate in a Combined Heat and Power (CHP) setup with a steam turbine to deliver clean heat and baseload electricity supply.
