To the editor: Los Angeles Department of Water and Power representatives have stated that gas-fired power plants are needed to provide electricity when solar and wind energy are not available.
The basis for this is the view that electrical energy storage technology is not currently developed sufficiently to provide economically viable grid-scale storage. However, recent advances in grid-scale energy storage technology provide encouraging evidence that in the near future we will be able to store power for widespread use economically.
The article “Advances in flow batteries promise cheap backup power,” published in the Nov. 2 issue of the journal Science, describes research being conducted in the United States, Great Britain and Singapore to determine the combination of materials to be used in flow batteries to provide the most economical grid-scale energy storage capability.
