Assessing the potential of hydrogen energy storage in a stand-alone electricity grid : applying mathematical programming to balance electricity production and consumption : a case study on the Faroe Islands
The increasing adaption of renewable energy sources (RES), with intermittent and nondispatchable production output, requires an increased effort to continuously balance supply to meet demand in electricity grids. Failing to establish this balance can lead to blackouts. Energy storage technologies ca...
