Energy storage with more than four hours of duration could assume a key role in integrating renewable energy into the US power grid on the back of a potential shift to net winter demand peaks, says the US National Renewable Energy Laboratory (NREL).Four-plus-hour energy storage accounts for less than 10% of the cumulative 9 GW of energy storage deployed in the United States in the 2010-22 period. However, this type of technology is likely to assume a more important and versatile role on the grid in the years to come, according to NREL's new publication. NREL's earlier studies identified economic ...Den vollständigen Artikel lesen ...
