Volume 3: Tools and Strategies to Enhance Non-Propulsion Efficiency

Abstract

This report, part of the Technology Pathways to a Low Carbon Fishing Fleet series, focuses on technologies and strategies that reduce non-propulsion energy demands on commercial fishing vessels, such as loads associated with deck machinery, refrigeration, lighting, hotel uses, and navigation equipment.

Based on interviews with 148 fishing businesses from across Alaska, the West Coast, and New England, the report explores real-world experiences, motivations, and barriers to adopting energy-efficient innovations, including four innovations featured in the interview questionnaire (load-sensing hydraulic pumps, electric deck machinery, LED lighting, and improved fish hold insulation) as well as numerous innovations introduced to the conversation by interviewees themselves.

Among fishermen who have already implemented energy-saving innovations, we find that benefits are not limited to fuel savings but also encompass co-benefits such as improved safety and operational versatility. Among fishermen contemplating adoption of efficiency innovations, we find that attitudes are positively influenced by a desire for fuel savings, and negatively influenced by a lack of familiarity, uncertainty about context-specific efficiency benefits, mistrust of complex technology, high costs, installation effort, and impacts to safety and operational routines. The report provides evidence of broad support for comprehensive inclusion of nonpropulsion efficiency innovations within state, federal, and private incentive programs.
