Researchers at MIT have developed a groundbreaking process to produce hydrogen from recycled soda cans and seawater, offering a sustainable solution for clean energy production. The innovation addresses the environmental challenges associated with traditional hydrogen production methods by utilizing common waste products. By treating recycled aluminium with a rare gallium-indium alloy, the researchers successfully enabled the reaction between pure aluminium and seawater to release hydrogen efficiently. This method emits significantly less CO₂ compared to fossil fuel-based processes, positioning it as a competitive green alternative. The cost-efficient production process, estimated at $9 per kilogram, provides logistical flexibility by allowing on-site hydrogen generation through the mixing of processed aluminium pellets with seawater. MIT's technology showcases the potential to power various transportation modes, from electric bicycles to small cars, with plans for exploring marine applications. Additionally, the process yields boehmite, a valuable by-product used in electronics industries, further enhancing its economic viability. This breakthrough promises to democratize hydrogen mobility, offering a green fuel option accessible to a wider audience.
