Energy storage grid balancing

What is grid balancing?

Grid balancing is when excess electricity from the grid is locally stored (in our application in form of H2) and then fed back into the grid as soon as demand for electricity exceeds supply. Grid balancing will increasingly become a necessity as the percentage of renewable energy rises in the energy mix.

What is grid-based energy storage?

Grid-based energy storage is a method of storing energy directly for the electrical grid. It addresses the issue of renewable energy sources not always being available, as energy can be stored during sunny and windy periods and released when needed.

What is grid scale energy storage?

Grid scale energy storage systems are increasingly being deployed to provide grid operators the flexibility needed to maintain this balance. Energy storage also imparts resiliency and robustness to the grid infrastructure. Over the last few years, there has been a significant increase in the deployment of large scale energy storage systems.

How do we balance the grid?

Inertia, frequency, voltage, thermal, constraintsthese are just a few of the factors that go into the highly complex process of balancing the grid.

Why is energy storage important?

Abstract: Today, the stability of the electric power grid is maintained through real time balancing of generation and demand. Grid scale energy storage systems are increasingly being deployed to provide grid operators the flexibility needed to maintain this balance. Energy storage also imparts resiliency and robustness to the grid infrastructure.

How can energy storage strengthen the grid?

The job of the grid is to deliver electricity to every customer at 120 volts and 60 hertz. This is accomplished by adding or removing current from the grid. A storage device helps by adding or removing current exactly when needed. Read on to learn how energy storage can strengthen the grid.
