Utility‑scale PV System

Develop PV resources at scale to establish an efficient green energy supply base.

Industry Overview

Power Transmission Solutions

The overall solution for hydrogen refueling stations constitutes a specialized integration system of engineering technologies. At its core is the establishment of a complete, efficient, and highly reliable technical chain for hydrogen handling, encompassing the stages of reception/preparation, purification, compression, storage, and refueling. This system typically comprises four principal subsystems: the front-end hydrogen supply module (comprising gas unloading units or on-site hydrogen generation systems such as electrolyzers or reformers), the high-pressure processing unit (including compressors, sequence control panels, and high-pressure hydrogen storage arrays), the refueling terminal (featuring pre-cooling units and hydrogen dispensers), and the integrated station control and safety management system.

Industry Challenges

Harsh Marine Environments

Resisting extreme water pressure and chemical corrosion over a 30-year lifespan.

Installation Complexity

Precision laying in varied seabed terrains to avoid mechanical damage.

Transmission Loss

Minimizing energy dissipation during long-distance underwater delivery.

Successful Cases

Dayangkou 110 MW Fishery‑PV Complementary PV Power Station

This project is a photovoltaic power station built by ZTT using fish farms in tidal flats. The fish-solar complementary model not only makes efficient use of aquatic space resources, but also improves the aquaculture environment by using photovoltaic panels to block sunlight and regulate water temperature, thus helping to achieve the dual goals of energy transformation and improving the quality and efficiency of agriculture/fisheries.

Guohua Rudong 400 MW Offshore PV Power Plant

This project is China’s first and largest integrated photovoltaic, hydrogen, and energy storage marine photovoltaic demonstration project. The Zhongtian team overcame multiple challenges in environmental, technical, and engineering aspects, and ultimately completed the project construction with high quality and quantity.

Huaneng Rudong 200MW PV Power Plant

This PV project is constructed on intertidal zone vacant land. It does not alter the intertidal zone’s original tidal-flat ecological features, and leverages coastal areas’ stable sufficient solar irradiation to guarantee power generation efficiency, realizing three-dimensional efficient land utilization.
