'Progress in electrical energy storage system: A critical review' by Chen et al. (2009) covers technologies like batteries, flow batteries, and fuel cells used in these systems, vital for balancing supply in renewable-heavy grids. These integrations reduce reliance on fossil fuels, as noted in 'Sustainable Hydrogen Production' by Turner (2004), where hydrogen from water supports sustainable energy carriers.
