Demand Grows for LGWP ORC Working Fluid

With the substantial energy producing and operating savings realized from ORC systems, the need for new working fluids is growing. From the exploration of ORC systems for use in transportation applications to the accelerating expansion of geothermal power stations, ORC is being considered for many industrial, municipal and government projects.

Honeywell is working to bring you the next generation of working fluid products as alternatives to 134a and 245fa that will offer:

  • Ultra Low-Global-Warming Potential – GWP values are orders of magnitude lower than existing HFCs, and comparable with hydrocarbons.
  • Performance – Potential improvements in system efficiency compared with some existing HFCs.
  • Safety – Safer than highly flammable hydrocarbon working fluids with low toxicity.
  • Cost – Comparable system economics to working fluids in use today.
