{{Short description|Type of positive-displacement rotary gas compressor}}
The '''guided-rotor compressor''' ('''GRC''') is a positive-displacement rotary gas compressor. The compression volume is defined by the trochoidally rotating rotor mounted on an eccentric drive shaft<ref>[http://www.grcompressor.com/#section2 GRC - Detailed description and defining geometry]</ref><ref>[http://www1.eere.energy.gov/hydrogenandfuelcells/pdfs/liquefaction_comp_pres_praxair.pdf Hydrogen delivery liquefaction & compression] {{webarchive|url=https://web.archive.org/web/20120314052342/http://www1.eere.energy.gov/hydrogenandfuelcells/pdfs/liquefaction_comp_pres_praxair.pdf |date=2012-03-14 }}</ref> with a typical 80 to 85% adiabatic efficiency.<ref>{{Cite web |url=http://www.canadianpurcell.com/UserFiles/File/MechanicalPerformanceFeaturesGRC.doc |title=Mechanical properties |access-date=2009-10-24 |archive-url=https://web.archive.org/web/20110708113337/http://www.canadianpurcell.com/UserFiles/File/MechanicalPerformanceFeaturesGRC.doc |archive-date=2011-07-08 |url-status=dead }}</ref>
==History== thumb|As the guided-rotor compressor rotates around the eccentric shaft, the central rotor pumps fluid The development of the GRC started in 1990 to minimize the use of compressor valve plates and springs by using simple inlet/discharge ports.<ref>[http://www.grcompressor.com/#section11 Development history]</ref>
==Uses== The guided-rotor compressor is under research as a hydrogen compressor for hydrogen stations and hydrogen pipeline transport.<ref>[http://corridoreis.anl.gov/documents/docs/technical/APT_61012_EVS_TM_08_2.pdf Overview of interstate hydrogen pipeline systems]</ref>
