HyZET: A Design and Feasibility Study of a Fuel Cell-Powered Commercial Harbor Craft
Design of a Hydrogen Fuel Cell-Powered Tugboat for the Port of Angeles
Following approval at the March 2021 business meeting, this project was executed and kicked off in April 2021. CALSTART is in the process of finalizing subcontracts and Technical Advisory Committee members with each member of the HyZET consortium. CALSTART is facing some delays due to its current contract backlog.
This project is supporting the Hydrogen Zero Emission Tugboat (HyZET) consortium, which comprises leading maritime stakeholders with expertise in electric propulsion system integration, fuel cell energy solution production, feasibility analysis, technology qualification, independent safety and quality assurance, vessel operation and design, LH2 integration, and upstream LH2 production. The HyZET consortium is developing an actionable hydrogen fuel cell-powered tugboat design that will be ready for construction and implementation at the Port of Los Angeles. The vessel design and feasibility study is addressing challenges related to using LH2 to power the tugboat, including how LH2 can be produced and delivered to the port.
This study will identify pathways to economically support the HyZET tugboat operation. As hydrogen demand increases to support the HyZET tugboat, the costs of transitioning other port applications can be reduced through scale.
Deploying a single hydrogen fuel cell-powered tugboat at the Port of Los Angeles can result in 180,000 gal/yr of avoided diesel consumption and 2,240 metric tons/yr of CO2 emissions savings.
