Hydrogen Power
Stanford scientists have proven they can use solar power to convert salt water taken directly from San Francisco Bay to create hydrogen gas.
On a larger scale, the process could achieve a truly pollution-free and carbon-neutral energy source to power cars and other devices.
Current methods of splitting water into hydrogen and oxygen require the use of expensive purified water, which doesn’t corrode the electrodes that produce the splitting as does seawater at high voltages.
The researchers found that by using electrodes rich in negatively charged layers of nickel-iron hydroxide and nickel sulfide over a nickel foam core, the corrosion is significantly reduced.
