Scientists at MIT have discovered a new way to extract high-purity hydrogen from ammonia while using a lot less energy than previous technologies. The breakthrough could provide a critical inroad toward reducing the energy and ecological footprint of the hydrogen sector, which powers a wide range of industrial processes and technologies from fuel cells to computer chip manufacturing. Green hydrogen has often been touted as a silver-bullet solution for decarbonizing hard-to-abate sectors like the shipping industry and steelmaking, as…
