Barriers and Drivers to the Implementation of Onshore Power Supply-A Literature Review

Onshore power supply (OPS) reduces emissions from vessels docked in port. Historically, the uptake of OPS has been low, and research indicates that potential OPS adopters face multiple complex barriers. Based on a systematic literature review, this paper presents a framework for categorizing barriers and drivers to the implementation of OPS and identifies potential areas for future research. The review indicates that research on barriers to OPS was limited until 2019, when interest increased considerably, coinciding with mounting stakeholder concerns and regulatory pressure. The suggested framework divides barriers and drivers divided into four key categories: (i) technology and operations, (ii) institutional elements, (iii) economic elements, and (iv) stakeholder elements. The framework then superimposes those categories on three main areas of concern: port, transmission, and vessel. Research has identified potential solutions to specific barriers, but the complexity of OPS highlights the need for a collaborative approach to OPS. Additionally, as regulatory pressure is rising, more research is needed on the systemic implications of OPS as well as the potential use of incentives, pricing, and business models to tackle the high cost of implementation.
