gjm 3258 Report post Posted March 3, 2022 We've talked about development of fuel cells for cars, and the issues (BMW and others) will face. The strength required of the hydrogen container typically dictates a specific shape, and that's something requiring significant R&D. Other issues have been the transportation of hydrogen, somethng which could be overcome by producing the hydrogen locally, on a smaller scale. That has also raised questions of ability and efficiency. A new development may have changed the picture. An easily produced composite of gallium and aluminum creates aluminum nanoparticles that react rapidly with water at room temperature, yielding large amounts of hydrogen. The gallium is easily recovered for reuse after the reaction, and testing has shown the reaction yields 90% of the hydrogen that could theoretically be produced from the reaction of all the aluminum in the composite. The process doesn’t require any energy input, and it bubbles hydrogen like crazy. The reaction of aluminum and gallium with water works because the gallium removes the passive aluminium oxide coating, allowing direct contact of aluminum with water. Transport of the gallium/aluminium is very, very easy and presents no significant risk. Quote Share this post Link to post Share on other sites

I think it is a great idea, but there will be a limit on how much it can make at the time. Edited March 3, 2022 by lord_jagganath Quote Share this post Link to post Share on other sites
