IMPROVE VESSEL EEDI
Improve attained EEDI ratings and ensure regulatory compliance with onboard waste heat recovery systems. Reduce carbon emissions by 62,500 metric tons over a ship’s 25 year lifetime and decarbonize the shipping industry with future-proof, new build designs.
MEET EEXI REQUIREMENTS
Retrofit onto existing fleets to cut emissions and improve vessel EEXI ratings. Incorporate waste heat recovery on ships to meet new EEXI Regulations and maximize value from existing assets.
WHAT IS MARITIME ORC WASTE HEAT RECOVERY?

Repurpose waste heat & generate clean, carbon-free electricity
CAPTURE LOW-TEMP WASTE HEAT
More than 50% of a ship's fuel energy is wasted as heat and the majority of this heat is lost at low temperatures (80-120 degrees C). Climeon’s AWARD-WINNING HeatPower Marine system uses Organic Rankine Cycle (ORC) technology to capture and convert low-temp waste heat from multiple sources, including:
- Main engine
- Jacket cooling water
- Scavenge air/charge air
- Lubricating oil
- Surplus steam/thermal oil


GENERATE CARBON-FREE ELECTRICITY & REDUCE CO2 EMISSIONS
The Climeon Heat Power system is a WHR system that exploits the temperature differences between hot and cold water to generate clean electricity for your vessel’s grid. The Heat Power system uses principals of an ORC thermodynamic process to convert waste heat to power by utilizing the volume difference between gas and fluid state of a working media to generate a flow pressure over a turbine. Thus, it functions as a closed loop steam turbine system but uses an organic fluid instead of water as working media. The organic fluid has a boiling point lower than water, which enables the ORC system to generate electricity from waste heat at lower temperatures.

MARKET LEADING PAYBACK TIME
Enabled by world-leading low-temp conversion efficiency
REDUCED PAYBACK TIMES
Decarbonizing shipping, meeting EEDI and EEXI requirements and reducing GHG emissions can be cost-effective too. The clean energy produced by Climeon HeatPower Marine systems can cut fuel consumption by 5%, leading to cost reductions, regulatory compliance and more sustainable shipping.
SAFETY-FIRST DESIGN TO MEET INDUSTRY STANDARDS
The shipping industry is heavily regulated to ensure enhanced safety on board, in dock and on shore. Climeon’s HeatPower technology is project certified by ABS, DNV-GL and Lloyd’s Register, and is designed to meet and exceed the sector’s stringent safety requirements.
FUTURE-PROOF MARITIME ORC TECHNOLOGY
As regulations are strengthened and the industry becomes more environmentally-conscious, Climeon HeatPower Marine technology can be optimized to enhance energy outputs and deliver increased emissions reductions. Built to last for a vessel’s entire 25-year lifetime, HeatPower is designed for the future.
