Massachusetts Institute of Technology researchers have developed a new process to generate hydrogen from the reaction between aluminum and seawater, using a gallium-indium eutectic (eGaIn) to surface-treat the aluminum. Their study shows that adding a small amount of imidazole to seawater significantly accelerates this reaction, allowing for the recovery and reuse of over 90% of the eGaIn and producing nearly 99% of the expected hydrogen output. This breakthrough could lead to practical applications, such as onboard hydrogen generation for marine vessels, using aluminum pellets and seawater to power engines or generate electricity.
