Zero-Emission Truck TRU Technologies

Last updated September 23, 2024.
The zero-emission truck TRU technologies listed below may be used to comply with the zero-emission truck TRU requirements specified in the TRU ATCM. (See 13 California Code of Regulations 2477.5 (b)). Listing of trade names does not imply CARB endorsement in any way.
Zero-emission truck TRUs are not powered by an internal combustion engine in any way. Electric power for compressors, fans, and controls may come from on-board batteries, provided they are not re-charged by an alternator or generator that is driven by the vehicle engine or powertrain, trailer wheels, trailer axle/differential, or any other contrivance that adds to the vehicle engine load. Examples of zero-emission truck TRUs include, but are not limited to, truck TRUs with refrigeration systems and/or fans that are powered by batteries when on-road and use battery chargers that are plugged into the grid while stationary or connected to on-board solar panels.

Cryogenic refrigeration: Indirect injection liquid carbon dioxide; battery-powered electric fans circulate air; for truck and trailer applications. Indirect cryogenic refrigeration means cryogenic fluid flows through a heat exchanger and exhausts to ambient air, outside of the cargo space while fans blow air across the heat exchanger to cool the cargo space. | Thermo King ST-CR 300 (truck), SB-III CR (trailer) | |
| All-electric, plug-in refrigeration system for straight truck cargo boxes and vans, with battery pack on-road power and solar panel range extender. | Volta Air Pluto, Pluto Dual, Titan (Battery Electric Installs) |
