In this episode of Know Power, hosts Noha and Michael sit down with Christie Obiaya, CEO and Director of Heliogen, an energy technology company focused on concentrated solar power (CSP) and storage solutions. Christie shares her journey from chemical engineering to leading Heliogen and dives into the challenges and opportunities of CSP technology. The conversation explores how Heliogen is redefining renewable energy with CSP, addressing issues from energy access to industrial decarbonization. Christie discusses the evolution of CSP, its deployment challenges in the U.S., and its unique benefits, including higher efficiency compared to traditional solar PV. Tune in to discover how Heliogen’s innovative approach combines AI and advanced thermal storage to push the boundaries of clean energy.
