Renewable Energy‐Driven Green Electricity Supplement for Empowering Blue Economy

ABSTRACT The thriving blue economy is undergoing a key strategic shift from nearshore to distant‐ocean operations, which has created an urgent demand for stable, independent, and environmentally robust energy supply systems. Traditional infrastructure usually relies on fossil fuels or submarine cables, which are environmentally unsustainable and have high operating and maintenance costs. The existing renewable technology is difficult to operate stably in harsh marine environment for a long time. The extreme dynamic load and corrosive salt fog environment in the ocean will accelerate the degradation of materials and the instability of the system. In order to solve this dilemma, this perspective proposes a paradigm with renewable energy‐driven green power supply system as the core. The paradigm framework has four key components: (1) flexible perovskite solar cells (F‐PSCs) with long durability and high efficiency realized by active stress release mechanism and advanced packaging; (2) integrated triboelectric nanogenerator‐supercapacitor (TENG‐SC) devices by codesign and practical strategies for efficient tidal energy harvesting and storage; (3) grid‐forming (GFM) control strategies for stabilizing power output and managing multi‐physics coupling in low‐inertia, power‐electronic‐dominated offshore microgrids; and (4) AI‐driven digital engines accelerates the whole process from inverse design of materials to system‐level optimization. This paradigm breaks through the traditional way of pursuing a single technological improvement and focuses on building an integrated energy ecosystem. It provides an actionable solution for practitioners in related fields, and more importantly, it points the way forward for achieving global carbon neutrality and entering a new era of intelligent, resilient, and zero‐carbon blue economy.
