Marine  

The propulsion engines and auxiliary systems of marine vessels generate a significant amount of heat energy that can be converted into electric power using Calnetix’s Hydrocurrent™ Organic Rankine Cycle (ORC) Modules for marine applications. The power produced is often used to supplement shipboard auxiliary power.

Hydrocurrent modules also can generate electricity from the waste heat produced by turbomachinery equipment on offshore platforms, and floating, production, storage and offloading (FPSO) units to help power oil production processes.

Hydrocurrent is unique in that it can pull usable heat from a source with temperatures as low as 80°C (176°F) unlike other heat recovery systems that require much higher temperatures. It converts excess waste heat into electric power without affecting engine performance, and was designed and built to ClassNK and Lloyd’s Register guidelines.

The Hydrocurrent system uses an ORC heat recovery process with Calnetix’s patented Thermapower® and Carefree Integrated Power Module (IPM), which efficiently converts thermal energy into mechanical power. The core technologies comprising the Hydrocurrent and Thermapower ORC modules have been used for heat recovery in other industrial applications in the United States, Canada, Europe, the Middle East and Asia since 2009, and over 35 MW of capacity in land-based systems have been deployed.
