Dana to provide e-propulsion system for Class 8 truck hydrogen fuel development project in Alberta, Canada

Dana Incorporated will provide its Spicer Electrified e-Propulsion solution with integrated TM4 SUMO HP motor-inverter system to power Class 8 tractor-trailer units that will move freight year-round between Edmonton and Calgary in Alberta, Canada.

The trucks are part of a three-year, $11.2-million (C$15-million) Alberta Zero-Emissions Truck Electrification Collaboration (AZETEC) project, which involves the design and manufacture of heavy-duty, extended-range, hydrogen fuel cell electric hybrid trucks. (Earlier post.)

Dana’s custom Spicer e-System is optimized for the Canadian market with a hauling capacity of 140,000 pounds, the highest-rated electrified drivetrain system for linehaul applications. The system’s compact design reduces weight and allows for more hydrogen fuel storage, while high-speed helical gearing provides greater overall efficiency. Dana’s TM4 SUMO HP motor-inverter system was specifically designed for high-power applications, and multi-speed gearboxes.

The trucks, developed for Alberta’s unique operating environment, will be 64-tonne (gross vehicle weight) B-train tractor-trailers capable of traveling up to 430 miles (700 km) between refueling. They will be operated by Alberta trucking companies Trimac Transportation and Bison Transport. At the conclusion of the project, the trucks will have carried approximately 12 million tonne-miles of freight. . . .

Emissions Reduction Alberta (ERA) is committing more than C$7.3 million to the AZETEC project. This investment comes from ERA’s BEST Challenge—a $100 million funding opportunity for biotechnology, electricity, and sustainable transportation technology solutions. ERA funds projects using the proceeds from carbon pricing paid by large final emitters to reduce GHGs and build the resilience of new and incumbent industries in Alberta.

Ports of Auckland buys world’s first electric tug; 70-tonne bollard pull

. . . The new tug, a Damen RSD-E Tug 2513 to be delivered in 2021, will have a 70-tonne bollard pull, the same as the port’s strongest diesel tug Hauraki, also built by Damen. . . .

Ports of Auckland first started looking for a battery-powered tug in 2016. This will be the first full-sized electric tug, and it is designed for normal port operations. There is an electric tug under construction for use in Turkey, but it is small (18.7m), is designed with a conventional twin screw propulsion line (as opposed to the Azimuth propulsion in the RSD-E 2513) and will work in a very narrow and tight environment.

The new tug is an electric version of the existing Damen RSD Tug 2513, which was unveiled in 2018 featuring green credentials, being fuel-efficient and IMO Tier III ready. This made an ideal candidate for conversion to the first full-size, fully electric port tug.

There are also high levels of redundancy built into its power systems. The batteries arranged in strings; if one battery in a string fails, the others carry on the work.

To ensure absolute safety, the tug also has two 1000 kW back-up generator sets. They provide enough power for the tug to operate at 40 tonnes bollard pull in the event of an electrical system failure or if the vessel needs to operate for a longer duration.

The generators are fully IMO Tier III compliant engines and therefore the greenest option currently available.

The back-up generators are intended to be used very rarely. The new e-tug can do up to four shipping moves on a charge of batteries and can go in for quick charge if required.

The current 70-tonne bollard pull tug Hauraki uses around 120 liters of diesel per hour. In 2019 it consumed 190,926 liters of diesel equating to 514.33 tCO2e (figures for 2019, using MFE May 2019 emission factors).

The energy capacity of the e-tug’s batteries is 2800 kWh—the same as 70 Nissan LEAFs (based on a 40kW LEAF battery). Based on the Hauraki 2019 diesel consumption / number of ship pulls it is expected the electric tug will use approximately 501,685 kWh to operate in the same way, this equates to 49.02 tCO2e which would mean an annual saving of 465.31 tCO2e.

In future, Ports of Auckland hope to be able to use 100% renewable energy, which would reduce emissions to zero. The tugs account for approximately 10% of the total scope 1 emissions and approximately 8% of total gross scope 1,2 & 3 emissions; replacing all tugs represents a significant reduction in carbon footprint.

Tug dimensions: 6-metre draft, 24.73 Length

Propeller diameter: It will have two azimuth thrusters with 3-metre diameter propellers. . . .
