Researchers at Rice University have developed an innovative way to enhance thermophotovoltaic (TPV) systems, which convert heat into electricity using light. Drawing inspiration from quantum physics, engineer Gururaj Naik and his team designed a highly efficient thermal emitter that works within realistic design constraints.
This breakthrough has the potential to advance thermal energy storage, offering an affordable and scalable alternative to batteries for grid-scale energy solutions. More broadly, efficient TPV systems could drive renewable energy adoption, a crucial step toward achieving net-zero emissions. Additionally, improved TPV technologies could significantly reduce industrial waste heat, making manufacturing processes more sustainable. Currently, 20-50% of the heat used in producing consumer goods is wasted, resulting in over $200 billion in annual economic losses in the United States alone.
