On June 25th Alan McCorkle, President and CEO of Yusen Terminals located at the Port of Los Angeles showcased the acquisition of new battery-powered top handlers that will speed the transition from diesel technology to zero emission technology.
McCorkle told a group of dignitaries that included Los Angeles Mayor Karen Bass: "At YTI, we believe in leading by example and setting new standards for environmental responsibility in our industry. With the introduction of these electric top handlers, we are not only reducing our carbon footprint and continuing to support our local workforce, but also pioneering a greener future for global port operations."
However, in an interview with AJOT, McCorkle warned of a tough road ahead.
McCorkle said that top handlers play a crucial role in terminal operations by efficiently transferring containers to and from ships to trucks and trains. While traditionally powered by diesel engines, the introduction of the five brand-new electric top handlers represents a significant achievement for Yusen Terminals.
McCorkle also described the many challenges Yusen faces transitioning to zero emission cargo-handling equipment.
McCorkle told AJOT that Yusen was switching 8 of its 34 container top handlers to battery-power machines built by Taylor Machine Works, a leading U.S.-based heavy-duty equipment manufacturer already supplying top handlers at the Port.
The Taylor machines utilize Proterra batteries. As of February 1, 2024, the Proterra business line announced that it will operate as an independent company within the Volvo Group.
McCorkle explained: “These are the first commercially available units … that would go two consecutive shifts without an opportunity charge which is 16 hours … units that also had the Proterra battery … That's the holy grail for us … getting that ability to get a piece of equipment … on the terminal with 20–30-ton boxes that we're moving and being able to get consecutive shift application.”
McCorkle said the top handler is the terminal’s “workhorse” explaining:” Every container that comes off … of a ship … at Yusen is going be put into either a stack for local (truck) delivery, or it is going be put into a stack to load on to the train. Every box, every one of those boxes that gets in those stacks is being done by a top handler.”
In terms of loading onto a train “the top handler puts the container in a rail stack and the top handler is also going load the container onto the rail (train),” he said.
In the case of imports, “the rubber tire gantry (RTG) is the unit that is going to deliver that local import truck delivery … So, the top handler does not do that. But the top is putting it there for the RTG delivery and the local truck delivery application …That's, how I'm discharging a ship.”
On the export side, containers being loaded on to ships are transactions that are all made by top handlers: “Exports are being sent to a number of different destinations and … this does not lend itself to a huge stack … (as with imports using an RTGs.) You have got a lot of smaller shipments (going) to different destinations and so every box that goes on to a ship is being touched by a top handler. When an export box is coming in on the rail, we will discharge those with a top handler into an export stack that will be loaded to the ship with a top handler. The same thing happens with truck deliveries … come in through the gate by an over the road truck. That top handler is going to take that container off … and put into an export stack…. (until it puts it on) the yard tractor that's going to take it underneath the ship (with) the ship to shore crane, that will load it on to the ship.”
The challenge in making the transition from diesel-powered equipment to zero emission battery and hydrogen equipment is there number of cargo-handlers that need to be transitioned:
Still to be transitioned to zero emission operations are:
McCorkle explained the challenges for forklifts and pickup trucks: “I have to figure out … the non-handling equipment, … gasoline pickup trucks … that our frontline supervisors drive around to manage the operation. I have 161 of these then I have to buy EVs and then we have to plug those in… Those need electricity too. Then we also have to shift from the container handling equipment to the ancillary equipment we use, such as forklifts, which are diesel… we have some electric forklifts coming in …”
McCorkle said that Yusen is still testing equipment to see whether battery power or hydrogen fuel is going to work better for its cargo-handling fleet:
“We don't know if the battery going be better. We don't know if the hydrogen is going to be better … We are going to also be testing a hydrogen fuel cell top handler …when we talk about electrification, we think the solution to get to zero emissions (is) … probably going to need a combination of EV and hydrogen fuel cell.”
The terminals transitioning to zero emissions technologies are pioneering a major transformation away from diesel fuels at a time when battery-powered vehicles and hydrogen powered vehicles are still very expensive and require government grants for purchase and testing, he said.
While hydrogen is more expensive than diesel, there are still gradations of hydrogen generated by fossil fuels so that the zero-emission fuel needs to come from a process generated by a zero-emission source such as wind or solar adding a further complication to the procurement process: “Right now, hydrogen is very expensive. There are safety concerns with how you fuel. There are different kinds of hydrogen … And there is more we do not know about than we know about.”
