What Ener-T does

Ener-t International Ltd. is an Israeli renewable energy company founded circa 1980 by CSP pioneers who developed the original parabolic trough technology at LUZ for the SEGS projects in California. The company operates as a project developer, technology supplier, and EPC contractor delivering utility-scale solar thermal (CSP), photovoltaic (including floating PV and agro-solar), anaerobic digestion biogas, and battery/thermal energy storage systems across four continents (Israel, USA, Spain, India, China). Its technology stack centers on the proprietary ES-3.5 parabolic trough collector, two-tank molten salt thermal energy storage, Battery Energy Storage Systems (BESS), the patented Integrated Hybrid Solar Fuel (IHSF) system for 24/7 baseload solar generation, and a proprietary in-house Simulation Model for performance and financial modeling. The company claims 23% annual efficiency and 30% capacity utilization factor for its trough technology and a patent enabling over 90% annual capacity factor with 51%+ solar share via IHSF hybridization.
