Sossina M. Haile

Pioneering materials scientist who revolutionized sustainable energy solutions

Born in 1966 in Addis Ababa, Sossina M. Haile developed the world's first solid acid fuel cell - a groundbreaking technology that converts hydrogen and oxygen into electricity with near-zero emissions. Her work in alternative energy systems has challenged traditional power generation methods and earned her the 2020 Gregori Aminoff Prize from the Royal Swedish Academy of Sciences.

As the Walter P. Murphy Professor of Materials Science and Engineering at Northwestern University, Haile created superionic conductors that operate at intermediate temperatures (200-300°C), solving long-standing challenges in fuel cell commercialization. Her team's 2022 breakthrough in electrochemical ammonia synthesis provides a carbon-free alternative to fertilizer production, potentially transforming global agriculture.

Beyond technical innovations, Haile co-founded Sasol Solar Hydrogen Project in South Africa, demonstrating renewable energy solutions for developing nations. She actively mentors African STEM students through the Haile-Manas Academy in Ethiopia, proving that advanced research and social impact can coexist.
