HyZet tug design team hosts TTB panel next week

Written by Heather Ervin
Marine Log TTB Conference

Wrapping up Day 1 of Tugs, Towboats & Barges (TTB) 2023 on March 7 is a panel discussion with the members of the HyZet tug design team. Panelists include experts from Crowley Engineering Services, DNV GL USA, ABB Marine & Ports, and CalStart.

The panel will discuss the ongoing hydrogen fuel cell-powered tug design that will be ready for construction and implementation at the Port of Los Angeles. During their discussion, panelists will address the challenges related to using liquid hydrogen to power the tug as the research, design, and modeling work for this project has been worked on directly by the members of the panel.

This discussion will examine greenhouse gas emissions, hydrogen costs, maintenance, and other hydrogen fuel-related items. The HyZet tug project goal is to enable decarbonization of multiple sectors by developing a pathway to use hydrogen fuel cells in a megawatt-scale harbor craft application.
