Solar power is a great source of green energy, but it can also be inconsistent.

When clouds pass over or the sunlight adjusts, solar-plant electricity outputs can move up and down like a volatile stock. This can make power-grid stability complicated.

A recent study from Khalifa University suggests that these volatilities can be tempered by allowing batteries and hydrogen storage to work together.

Batteries can manage and handle quick changes in power, while extra energy can be utilized to produce hydrogen. The hydrogen is then stored and later converted back into electricity with fuel cells.

This system’s control strategy constantly monitors battery charge, hydrogen levels and efficiency to determine how to share the workload in real time.

The simulations reveal that this method reduces battery degradation by approximately 50 percent while maintaining much smoother solar power flow to the grid.
