Electrifying America's Ports with Solar Reef: A Robust and Nature-Positive Fixed-Bottom Offshore Solar Solution

Abstract Coastal communities and ports face growing energy demands from electrification while also confronting increasing threats from sea-level rise and storm damage. Ports, as major economic hubs, contribute significantly to greenhouse gas emissions and air pollution, often disproportionately impacting vulnerable communities. SolarReef™, a fixed-bottom offshore solar platform, addresses these challenges by integrating 3D concrete-printed artificial reef foundations with bifacial solar panels and battery energy storage systems to deliver clean, renewable energy. Beyond energy generation, SolarReef serves as a living breakwater, reducing wave energy and promoting marine biodiversity to enhance coastal resilience. As SolarReef continues development, a detailed levelized cost of energy analysis will be conducted. While an exact figure is not yet available, the goal is to achieve an LCOE between $93/MWh and $120/MWh, aligning with the cost range of commercial rooftop photovoltaics and offshore wind, respectively. Additionally, its 3D concrete-printed foundation reduces costs by over 75% and carbon emissions by more than 50% compared to steel platforms. This paper details the design, manufacturing, and deployment considerations of SolarReef. A case study proposal explores the feasibility of deploying SolarReef to support a National Security Multi-Mission Vessel (NSMV), demonstrating its potential for nationwide adoption as a scalable, dual-purpose solution for port electrification and coastal resilience.
