Energy Transformation Breakthrough: Tidal-Photovoltaic Hybrid Systems Reshape Power Generation

Background:

As the lifeblood of national economic development, energy serves as both a critical growth engine and a primary focus for carbon reduction under China's "Dual Carbon" goals.  Accelerating energy structure transformation is vital for advancing manufacturing energy efficiency and emissions reduction.

Policy-Driven Clean Energy Expansion
China's current clean energy portfolio primarily includes solar and wind power.  The "2022 Energy Work Guidance" mandates vigorous development of wind-PV integration, specifically:

    • Establishing new energy systems centered on large-scale renewable bases

    • Utilizing efficient coal power for regional support

    • Deploying ultra-high voltage transmission networks

    • Optimizing offshore wind layouts with deep-sea demonstrations

    • Advancing hydro-solar complementary bases

    • Implementing county-wide rooftop distributed PV projects

    • Launching localized "Thousand Village Wind Action" and "Thousand Household Lighting Action" initiatives

    • Developing distributed wind/PV on oilfields, industrial sites, and industrial parks

    •  Enhancing renewable consumption mechanisms with provincial responsibility quotas

    • Improving green certificate systems for renewable power

Beyond Wind and Solar: Tidal Energy Innovation
The concept of tidal-photovoltaic power stations integrates two complementary technologies:

    1.Tidal power harnesses water-level differences between high/low tides to drive turbines

    2.Photovoltaics convert sunlight directly into electricity via the photovoltaic effect

Traditional challenges include:

High infrastructure costs for tidal stations in deep-water harbors

PV generation limitations due to daylight/weather dependency

Breakthrough Integration: The Tidal-PV Hybrid Solution

On May 30, China's pioneering tidal-PV facility—National Energy Group Longyuan Power's Zhejiang Wenling Station—achieved full-capacity grid connection.  This represents the nation's first successful integration of lunar tidal and solar energy through:

    • Installing PV panels across tidal reservoir surfaces

    • Creating coordinated tidal-PV generation cycles

    • Stabilizing output by modulating tidal generation during PV fluctuations

    • Maximizing marine resource utilization while boosting total yield

Expanding the "PV+" Ecosystem

Recent policy directives from the NDRC and National Energy Administration promote diversified applications:

    • Developing standards for PV-integrated ecological projects (e.g., desert control)

    • Transforming energy storage systems from grid-adaptive to grid-supportive
    • Leveraging millisecond-response capabilities for enhanced grid stability
      This technological convergence significantly advances new power system development and industrial    energy restructuring.
