A sustainable way to generate hydrogen fuel

A pebble-sized pellet of aluminum, dropped into a beaker of filtered seawater, produces hydrogen gas that bubbles up and out of the container within a few minutes. MIT engineers are optimizing this simple chemical reaction as an efficient and sustainable way to generate hydrogen fuel, which they envision can be used to power an engine or fuel cell aboard marine vessels and underwater vehicles.

Our mission is to advance knowledge; to educate students in science, engineering, technology, humanities and social sciences; and to tackle the most pressing problems facing the world today. We are a community of hands-on problem-solvers in love with fundamental science and eager to make the world a better place. The MIT YouTube channel features videos about all types of MIT research, including the robot cheetah, LIGO, gravitational waves, mathematics, and bombardier beetles, as well as videos on origami, time capsules, and other aspects of life and culture on the MIT campus. Our goal is to open the doors of MIT and bring the Institute to the world through video.
