Company Overview

The Rondo Heat Battery converts intermittent wind and solar power into a simple, safe, practical, efficient, and affordable supply of continuous industrial heat and power.

Rondo reduces operating costs while eliminating emissions - and is available at scale today.

Electrification of industrial heat has been called "the next trillion-dollar market." Recent studies have found that the decarbonised world will need twice as much heat battery storage as grid battery storage, and that heat batteries will greatly reduce energy costs to produce many key commodities in the coming few years.

Rondo Energy's Impact

Energy-intensive industrial processes power our economies and produce our commodities. But, the high-temperature heat they require is the world’s largest source of CO₂ emissions. Until now, intermittent renewables have struggled to provide 24/7 high-temperature power needed by industry.

Rondo Energy's Mission and Values

Rondo’s mission is to help the world's most energy-intensive industries rapidly reach zero carbon emissions, at lower cost than fossil fuels and at large scale, today.

Current Investors

Investors include, Breakthrough Energy Ventures, Microsoft, Rio Tinto, Energy Impact Partners, SCG, Titan Cement Group, Aramco Ventures and many more.

How will Rondo Energy Use Funds Raised?

Rondo will use this funding to grow its international operations and to develop and build storage projects around the world.

What are the risks associated with Rondo Energy?

Rondo Heat Batteries store energy at half the cost of other technologies such as green hydrogen and chemical batteries. Rondo based its innovative technology on materials that heavy industry has used for more than a century for heating and heat storage: brick and iron wire. By building Heat Batteries with materials already made at large scale for more than a century, Rondo has eliminated the safety, durability, and supply chain risks faced by other storage technologies.

Policymakers and business leaders face shareholder pressure to deploy cost-effective and reliable climate solutions, Rondo's technology is a proven and effective tool for rapid and deep decarbonization across the world's most energy intensive and difficult to decarbonize industries.
