Maximizing Power Outputs and Emissions Reductions with Low-Temp ORC WHR

Low-temp ORC WHR systems, such as Climeon’s HeatPower 300 Marine system, utilize an Organic Rankine Cycle (ORC) to generate carbon-free electricity on ships. By harnessing the varying pressure of a cold input source (seawater) and a hot input source (waste heat) to power a turbine, these systems operate whenever the ship’s engines are in use and waste heat is being produced.

The HeatPower 300 Marine system takes advantage of on-board waste heat from temperatures as low as 80°C. This allows for a significant increase in the conversion of waste heat into sustainable electricity, leading to higher power outputs and subsequent reductions in emissions. What sets Climeon’s low-temp ORC HeatPower 300 Marine technology apart is its ability to operate using waste heat from a single source, such as jacket cooling water. This simplifies the integration process, resulting in additional cost savings and faster installation.

Waste Heat Recovery: Combining Profitability with Sustainability
In the past, increasing sustainability and reducing emissions were viewed as costly compliance issues. However, innovative maritime technology has demonstrated the potential for sustainability to go hand in hand with profitability. This has motivated shipowners and operators to embrace a more sustainable future. Climeon’s HeatPower 300 Marine system has proven that integrating waste heat recovery systems on board vessels can have a positive economic impact and offer an attractive return on investment. The production of clean electricity on board reduces fuel costs, and simplified integration options, reduced payback periods, and lower cost-per-produced kilowatt all contribute to the economic incentives that make waste heat recovery a popular sustainable technology among leading shipowners and shipbuilders. Furthermore, HeatPower 300 systems can be easily retrofitted onto existing vessels or integrated into new-build ships. With the potential to reduce carbon emissions by 100,000 metric tons over a ship’s 25-year lifespan and relatively short payback periods, HeatPower 300 Marine is a viable and cost-efficient method of emissions reduction for both current fleets and new vessels.

Future-Proofing the Shipping Industry
As updated regulations on emissions reduction are set to be enforced, the maritime sector is under time pressure to find solutions. Shipping companies are seeking long-term strategies that deliver both environmental and economic benefits throughout a vessel’s lifetime, making low-temp ORC WHR systems particularly well-suited to the industry. Climeon’s HeatPower 300 Marine system can be combined with other on-board sustainable technologies to maximize emissions reductions and fuel conservation. This allows shipping companies to achieve optimal emissions and cost savings by customizing the ship’s sustainable technology to match its design and operational route.
