Study shows making hydrogen with soda cans and seawater is scalable and sustainable

MIT engineers developed a process to produce hydrogen fuel with a lower carbon footprint using recycled aluminum, seawater, and a gallium-indium catalyst. This method emits only 1.45 kg of CO2 per kg of hydrogen, compared to 11 kg for fossil fuel-based methods. At $9 per kg, the cost is comparable to other green hydrogen technologies, with potential for further reductions. The process could revolutionize hydrogen production for transportation and remote energy systems.
