Efforts, led by Japan and South Korea, to use liquid hydrogen as the basis for a new energy economy.
Australian scientists claim they've worked out a much cheaper, more efficient way to split hydrogen out of water, using easily sourced iron and nickel catalysts. The discovery could greatly improve the equation for "green" hydrogen.
Japan wants to move towards a clean, hydrogen-based energy economy, but to make that happen, it'll need to import liquid hydrogen from elsewhere. Meet the Suiso Frontier, the world's first liquid hydrogen transporter. It runs on diesel.
