How does it work?
The Organic Rankine Cycle
The Organic Rankine Cycle (ORC) is a thermodynamic process that converts low-temperature waste heat into electricity. Climeon’s HeatPower system utilizes an organic fluid with a lower boiling point than water in a closed-loop design. Heat evaporates the fluid, turning it into pressurized gas to drive a turbine and generate power. The fluid is then cooled, condensed back into a liquid, and recirculated. The system's efficiency depends on the thermal energy available and the temperature gradient between the heat source and cooling medium.
Convert waste heat into SUSTAINABLE ENERGY ACROSS A RANGE OF APPLICATIONS
Waste heat recovery can be used across a variety of sectors to generate clean electricity, increase energy efficiency and reduce CO₂ emissions. Climeon’s HeatPower technology targets the most energy-intensive processes and industries to maximize environmental savings and deliver the biggest impact.
HEATPOWER CONTROL SYSTEM
FLEXIBLE, AUTONOMOUS AND RELIABLE POWER SYSTEM
HeatPower 300's control system enables autonomous operation, effortless monitoring and management of electricity production and can be easily integrated into a site’s existing management system. The product requires minimal routine on-site supervision and automatically adjusts to variations in hot and cold water temperatures and flows, maximizing the efficiency and output from the heat available.

Kopsvatn Power Plant
The Kopsvatn Power Plant is located just outside Flúdir in southeast Iceland. The area is rich in geothermal heat, mainly used for district heating and green houses. The construction of the powerplant began in May 2018 and commissioning was finished in March 2019. In 2020, upgrades to the cooling solution and a new pump made it possible to expand the power plant to a production capacity of 1.2 MW. The electricity produced is fed to the local grid and remaining heat is fed into the district heating network.
