## Summary

Rondo Energy builds heat batteries that store renewable electricity as high-temperature heat for industrial processes, decarbonizing hard-to-abate manufacturing.

## Company Overview

Rondo Energy is a clean energy company founded in 2020 focused on industrial decarbonization through thermal energy storage. The company builds brick-based heat batteries that store cheap renewable electricity as high-temperature heat up to 1500 degrees Celsius, which can be delivered on demand as steam, hot air, or direct heat for industrial processes including cement, chemicals, food production, and paper manufacturing. Industrial heat represents roughly 20% of global carbon emissions and has been among the most difficult sectors to decarbonize because most industrial processes require consistent high-temperature heat that electricity alone cannot easily provide. Rondo's technology eliminates the need for fossil fuel combustion in industrial heating by storing excess renewable energy during low-cost periods and dispatching it as heat when needed. The company raised over $100M and has deployed commercial projects with major industrial customers including Linde and Siam Cement Group. Rondo Energy addresses a massive decarbonization opportunity that electrification and carbon capture alone cannot fully solve.

## Frequently Asked Questions

### What is Rondo Energy?
Rondo Energy builds heat batteries that store renewable electricity as high-temperature heat up to 1500°C, enabling industrial manufacturers to replace fossil fuel combustion with stored clean energy for processes like cement and chemicals production.

### Why is industrial heat storage important for decarbonization?
Industrial heat accounts for roughly 20% of global CO2 emissions, yet most industrial processes require consistent high-temperature heat that batteries and direct electrification cannot easily provide. Thermal storage bridges renewable electricity to industrial heat demand.

### What industries does Rondo serve?
Rondo serves heavy industry including cement manufacturing, chemical production, food and beverage processing, and paper manufacturing, where high-temperature process heat is a core operational requirement.

### What is Rondo Energy's core technology and what does it store?
Rondo Energy's Heat Battery stores energy as high-temperature heat in refractory brick that is heated by electric resistance elements powered by renewable electricity — the stored heat reaches temperatures above 1,500°C and is delivered as continuous industrial process heat or steam to manufacturing facilities, replacing natural gas combustion for industrial heating applications that represent approximately 20 percent of global carbon emissions.

### Why does Rondo focus on industrial heat rather than electricity generation?
Industrial process heat is one of the largest and hardest-to-decarbonise sources of carbon emissions because it requires continuous high-temperature heat that cannot be provided by intermittent solar and wind directly — Rondo's Heat Battery bridges this gap by converting cheap renewable electricity during periods of oversupply into stored heat that delivers continuous process heat to industrial customers regardless of whether the sun is shining or wind is blowing.

### What industries and processes can Rondo's Heat Battery serve?
Rondo's Heat Battery can serve any industrial process that currently uses natural gas, coal, or biomass for high-temperature heat — including cement kilns, food and beverage sterilisation, chemical manufacturing, pulp and paper processing, and breweries — anywhere that steam or hot air between 150°C and 1,500°C is the primary energy need and direct electrification with heat pumps cannot reach the required temperatures.

### What is the economics case for an industrial customer to adopt Rondo?
Rondo can deliver industrial process heat at a lower cost than natural gas in regions where renewable electricity is cheap and abundant such as the US Southwest, Chile, and parts of Europe — because the Heat Battery charges during hours when solar or wind oversupply pushes wholesale electricity prices to near-zero, providing a path to both cost reduction and carbon reduction simultaneously rather than requiring a financial sacrifice for sustainability.

### What is the current commercialisation status of Rondo Energy?
Rondo Energy has deployed pilot installations with industrial customers including a facility operated by Kraft Heinz and has announced projects in Asia and the Americas — the company is in the early commercial deployment stage, scaling manufacturing capacity and developing project financing structures that allow industrial customers to adopt the Heat Battery without large upfront capital expenditure.
