Near Zero Emissions TRANSTAINER® Crane
The Near Zero Emissions TRANSTAINER® crane is an updated version of the PACECO®-Mitsui well-established hybrid Transtainer, featuring a power module combination of larger capacity lithium-ion batteries directly providing power to operate the crane and a small engine primarily used to recharge the batteries.

Considering the lifetime of an RTG is 15-20 years, the NZE TRANSTAINER® crane can meet terminal needs today and in the future as a zero emission (ZE) crane with a upgrade to a zero emission power source. This source can be electric, although this solution reduces yard flexibility and increases civil works investment. We believe the best solution is a hydrogen fuel cell power source to maintain a flexible yard operation and designed the crane for a fuel cell upgrade without modification of other drive systems or mechanical parts.
Zero emission technologies such as hydrogen fuel cell power modules are advancing. The PACECO® Group is aggressively proceeding with ZE solutions, and currently developing a hydrogen fuel cell power module for ZE Transtainers. This will easily enable the Conversion of NZE TRANSTAINER® to a ZE Transtainer by simply replacing the diesel generator with a hydrogen fuel cell power module , and plan to complete in-house testing of ZE Transtainer by March 2023.

The major improvement from the Hybrid TRANSTAINER® is the redesign of the electrical system and integration software to minimize power loss and thus create the ability to run the crane with a small diesel engine. The smaller engine has these benefits to port and terminal end users:
- Fuel reduction of approximately 70% compared to a conventional RTG
- Reduction of CO2, NOx, and PM particulates
- Lower maintenance costs due to the smaller engine size
- Ready for an easy upgrade to a zero emission crane by replacing the small diesel genset with a fuel cell power module, once hydrogen infrastructure can support
