As costs of variable renewable energy keep falling steadily and more renewables are deployed, the need to deploy storage solutions becomes more pressing. However, lithium ion (Li-Ion) and other chemical batteries are still either too expensive or inappropriate for storing energy at utility scale for more than four hours. Thermal storage can often give the flexibility to complement PV and wind production for long duration at a lower cost.
In this webinar we analyze the techno-economic advantages of integrating long-term thermal energy storage systems in variable renewable generation projects:
