Thinking big and starting small: Identifying considerations for small‐scale tidal energy in Southwest Nova Scotia

Abstract

Nova Scotia’s marine renewable energy (MRE) sector can contribute to provincial goals for carbon neutrality. Within Nova Scotia, tidal energy has been an interest to industry stakeholders for over two decades, yet general momentum for the industry has shifted. Previous tidal energy projects and recent studies suggest a broader consideration for the role that scalable tidal energy (i.e., small-scale) development can play in the province. This research explores considerations of developing tidal energy in Southwest Nova Scotia with an emphasis on small-scale tidal devices. Using a literature review and semi-structured interviews with stakeholders from different sectors of Nova Scotia’s MRE energy industry, key issues and challenges were explored. Results underline four main themes that affect industry growth potential, which include cost and financing, technology, policy, and energy distribution. The discussion highlights key insights regarding the value of small-scale technology, regulatory pathways and collaboration, and using global best practices to accelerate tidal energy industry goals in Nova Scotia.
