Seasonal storage and Hydrogen’s contribution towards it discussed. The study included the cost of seasonal storage based on the power capacity and energy capacity. While that is common in energy storage analysis, the researchers included potential revenues of capacity value, which is the cost to build new peaking plants to supply electrical demand; and, uniquely, accounted for avoided grid operating costs. Previous studies into energy storage do not consider the potential benefits to the grid. Using that information, a benefit-to-cost ratio analysis was conducted to determine the profitability of the storage technologies.
