Production Scale-Up of Thermionic Energy Harvesters
Document Type
NOE - Notice of Exemption
Document Description
This project will develop capabilities for low-rate initial production (LRIP) of Spark's prototype thermionic energy harvesters. These devices can dramatically increase concentrated solar power (CSP) plant efficiency and simultaneously increase the cost effectiveness of CSP. They will thereby increase CSP capacity development projects in California and enable progress towards the state's ambitious renewable energy targets. key activities of this project consist of cost modeling at the LRIP stage, scale-up of device component manufacturing and device assembly, and screening and testing of these components and devices.
