Electricity storage and renewables: costs and markets to 2030

Like solar photovoltaic (PV) panels a decade earlier, battery electricity storage systems offer enormous deployment and cost-reduction potential, according to this study by the International Renewable Energy Agency (IRENA). By 2030, total installed costs could fall between 50% and 60% (and battery cell costs by even more), driven by optimisation of manufacturing facilities, combined with better combinations and reduced use of materials. Battery lifetimes and performance will also keep improving, helping to reduce the cost of services delivered. Lithium-ion battery costs for stationary applications could fall to below USD 200 per kilowatt-hour by 2030 for installed systems.
