Wind power to hydrogen energy storage

What is a wind power-hydrogen-energy storage system?

Wind power-hydrogen-energy storage system. When wind power is abundant, surplus electricity exceeding what is needed for residential and industrial use is utilized for hydrogen production and stored in hydrogen tanks.

How does a hydrogen storage system work?

Hydrogen storage systems can balance the hydrogen demand and supply, thus improving the responsiveness to wind fluctuations. It is also possible to convert the hydrogen back into electricity via fuel cells during low wind power or peak demand, ensuring a continuous power supply.

How does a wind energy system work?

The system flexibly adjusts the wind power allocation ratio based on real-time load demand and the state of energy storage and optimizes hydrogen storage and fuel cell usage to compensate for power shortfalls during certain periods. This strategy yields a daily economic benefit of 1.047 million CNY and a daily power fluctuation of 6.37 GW.

What are the goals of a wind power system?

The first goal is to maximize the daily operating profit based on the efficiency standards of wind power, hydrogen energy, and energy storage, and the price of electricity and hydrogen. The second objective focuses on system stability by meeting load demands and minimizing power fluctuations.

How does a hybrid wind farm system work?

This hybrid system simultaneously coordinates the scheduling of the wind farm, hydrogen production, energy storage, external grid, and local load. By optimizing the power distribution of the wind farm, the model aims to maximize the operational profits of the entire system. Fig. 3.

Can wind power generate green hydrogen?

A promising solution involves generating green hydrogen by using wind power. In parallel, as some wind power plants near the end of their operational life, crucial decisions about their future must be made. In this context, hybrid solutions emerge as promising renewable systems, offering resilient and cost-effective approaches.
