The intermittent nature of wind power and lower electricity demand in the summer present a challenge of how to best maximize the renewable energy source in Finland’s energy grid.
Because of increasing over-generation of wind power and the inclusion of solar power during the summer months, Finland is left with excess energy. Seeing the need for a flexible power grid, we researched the potential efficacy of one energy storage method: geological hydrogen storage.
Using the LEAP-NEMO modelling toolkit, we compared Finland’s estimated electricity generation with and without hydrogen storage. Our calculations found that hydrogen storage led to about a 69% decline in carbon dioxide emissions, as well as a reduction in the use of fossil fuel-based power and need to import electricity.
