The reasons why Hydrogen can benefit the country’s electricity grid balancing and transmission system are presented below.

Figure 7: How hydrogen can help the national electricity grid balancing

In order to match the energy supply and demand, grid balancing plays a vital role. Moreover, installing more renewable energies to the system, grid balancing becomes more unpredictable.
Therefore, during the windy nights, the wind farms have to stop electricity generation due to no demand. As a result, cause to cost of over £6m in 33days to shut-down the electricity generation.
An innovative solution to this issue is to send this excess electrical energy to electrolysis of water. Therefore pure hydrogen generated and can be stored in fuel cells or pumped to storage systems to reserve and used in the peak time.
