Concentrating solar power with heat storage could compete with batteries – pv magazine USA

For short-term storage in a 100% renewables grid, thermal energy storage located at concentrating solar power plants could compete with batteries, found a study using an idealized grid model. Seasonal storage needs could best be met with power-to-gas-to-power technology. March 15, 2022 William DriscollConcentrating solar power plus thermal energy storage (CSP+TES) could be cost-competitive with battery storage for achieving a least-cost 100% renewables grid in the continental US, researchers have found.For seasonal storage, power-to-gas-to-power had lower costs than CSP+TES.Researchers used a simple model of the grid that assumed free lossless transmission across the continental US. They said their results could guide future studies using more detailed models, and expected that a model realistically representing transmission would not fundamentally alter the relative roles of the…
