How to optimize hydrogen storage power generation system capacity?

A two-layer hydrogen storage power generation system capacity optimization configuration model was established, an improved particle swarm optimization algorithm was used to solve the improved hydrogen storage power generation system capacity optimization configuration model, and the capacity optimization configuration results were obtained.

Why should hydrogen storage systems be optimized?

The optimized configuration not only reduces the operating cost of the hydrogen generation and storage system, as well as the cost of equipment adjustment and penalties, but also improves the utilization rate and stability of the equipment.

What is a hydrogen storage power generation system?

A hydrogen storage power generation system model is established, and the photovoltaic power generation and hydrogen fuel cell power generation is calculated.

Can a hydrogen energy storage system reduce the dependence on public network?

The strategy can effectively reduce the dependence on the public network for power purchase. Yi Zhang et al. studied the capacity optimization configuration problem of hydrogen energy storage systems in both grid connected and disconnected situations .

How efficient is hydrogen storage?

Hydrogen storage systems assessed for efficiency, safety, and capacity (2010–2020). Efficient hydrogen storage requires −253 °C or 700 bar, posing major challenges. Electrolysis efficiency is 60–80%, with production costs of $5/kg hindering adoption. Economic viability needs >80% efficiency and <$2/kg production costs.

How does loss rate affect hydrogen storage capacity configuration?

As the system usage time increases, the losses in the system continue to increase, the electrochemical energy storage capacity configuration decreases, and the hydrogen storage tank capacity configuration increases. When the loss rate changes from 6 % to 7 %, the changes in capacity configuration is significant.
