San Joaquin Valley Zero-Emission Cargo Handling Demonstration Project

The San Joaquin Valley Zero-Emission Cargo Handling Demonstration Project accelerated commercial deployment of zero-emission off-road technologies by showcasing two state-of-the-art, battery-electric 30,000-pound forklifts with advanced cargo handling attachments at the Port of Stockton. These units significantly reduced greenhouse gas emissions and eliminated exposure to toxic diesel pollutants, benefiting surrounding disadvantaged communities. DANNAR developed a near-commercial off-road electric mobile platform with multifunction capabilities to replace conventional diesel equipment used at ports, warehouses, and intermodal yards. The project demonstrated the scalability, practicality, and cost-effectiveness of zero-emission heavy-duty cargo handling equipment, supporting the goals of the Sustainable Freight Action Plan, AB 32, SB 32, AB 118, and SB 535.

Vehicles/Equipment Funded:

Two DANNAR 4.00 Mobile Power Stations (MPS)—zero-emission, battery-electric 30,000-pound forklifts combined with additional heavy-duty cargo handling and freight attachments: one with a dump truck bed and the second with an electric vertical scissor-lift. MPS features:
  • 126kWh and 168kWh respectively in each MPS of energy storage in high-capacity BMW lithium-ion battery packs
  • Energy export panel with two 240VAC outlets and three 120VAC outlets
  • Four-wheel drive and four-wheel, multi-mode steering
  • Full-time 4X4 electric drive with regenerative braking
  • Drawbar Pull Capacity: excess of 600,000 lbs.
  • Submersible up to four feet
Two ChargePoint DC fast chargers to charge both MPSs and will provide opportunities to expand the fleet of zero-emission forklifts.

Lessons Learned:

  • Technology for zero-emission electric work vehicles has evolved to levels allowing for peak performance and productivity.
  • Tier 1 suppliers of off-road equipment are universally shifting focus and product development to electric components.
  • Operators are receptive to the enhanced machine operation and increased performance of ZEV machines.

Status Updates:

  • DANNAR completed assembly for the Mobile Power Stations and delivered them to the Port of Stockton for data collection.
  • DANNAR worked closely with the Port of Stockton to provide ongoing customization to the MPS to parallel the functional abilities of a baseline forklift.
  • Once the MPSs were deployed, carbonBLU worked with the Port of Stockton and DANNAR to establish and complete the emissions testing.
