Efforts, led by Japan and South Korea, to use liquid hydrogen as the basis for a new energy economy.
Blending renewably-generated hydrogen gas into existing natural gas pipelines could quickly and easily transport hydrogen across cities. SoCalGas is testing a system that can separate the H2 back out and compress it for use in fuel-cell vehicles.
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.
