District Energy Systems
District energy systems are highly efficient, sustainable, and resilient. They centralize heating, cooling, and power to minimize energy losses and carbon emissions. Despite its potential for decarbonization, fossil fuels still dominate district energy networks, representing the majority of total energy inputs. Rondo can repower district energy networks with clean intermittent electricity enabling a cost effective transition to zero carbon.

We help district energy systems transition to low-carbon and renewable energy sources in order to reduce emissions, lower operational costs, and enhance energy security, while maintaining flexibility and avoiding costly upgrades or retrofits.
Rondo seamlessly integrates into existing district heating and cooling networks, enabling operators to decarbonize their energy supply without the need for expensive retrofitting of thermal distribution infrastructure. Our solution maintains the flexibility and reliability of your current thermal systems and networks, offering a simple, cost-effective path to sustainability.

Key Benefits
Decarbonization Without Infrastructure Overhaul
Rondo's thermal heat battery allows for the decarbonization of district heating and cooling systems without the need to replace or upgrade existing thermal distribution infrastructure. This enables a cost-effective pathway to electrifying and decarbonizing district heating systems.
Operational Flexibility
Rondo enables district heating plants to maintain or enhance their operational flexibility. Using clean intermittent electricity, Rondo heat batteries can generate steam at conditions equivalent to existing combustion equipment, ensuring that the system can meet process loads, drive steam turbines, and/or power thermal cooling system as needed.
Cost-Effective Operation
By enabling flexible and intermittent charging during low-cost/low-demand energy periods, Rondo’s solution can deliver lower operating costs compared to traditional district heating operations and other direct electrification technologies.
Designed for your facility
Industry Challenges
District energy systems depend largely on fossil fuels, presenting obstacles for achieving sustainable operations.
In 2022, district heating accounted for approximately 9% of the global final heating demand in buildings and industry, demonstrating its significant role in the energy mix.
Despite its potential for decarbonization, fossil fuels still dominate district heating networks, representing 90% of total heat production.
