![]() ![]() The work confirms that, when combined with water, aluminum can provide a high-energy-density, easily transportable, flexible source of hydrogen to serve as a carbon-free replacement for fossil fuels.Īs the world works to move away from fossil fuels, many researchers are investigating whether clean hydrogen fuel can play an expanded role in sectors from transportation and industry to buildings and power generation. Such tuning can be used to meet demands for brief bursts of hydrogen, for example, or for lower, longer-lasting flows. Next, they showed that they could “tune” the hydrogen output by starting with pure aluminum or specific alloys and by manipulating the size of the internal aluminum grains. ![]() They then demonstrated ways of treating the samples to ensure that the surfaces of all the aluminum “grains” that make up the solid remain free of deposits throughout the reaction. First, they obtained specially fabricated samples of pure aluminum and aluminum alloys designed to replicate the types of scrap aluminum typically available from recycling sources. MIT researchers have produced practical guidelines for generating hydrogen using scrap aluminum and water. Their results show that by choosing a specific aluminum alloy from a waste heap and taking a few steps to modify it, a user can generate the flow of hydrogen needed for a particular practical application. Eagar have systematically studied how to generate hydrogen by combining aluminum with water. ![]() Laureen Meroueh PhD ’20 (pictured) and Professors Douglas P. ![]()
