A system has been created for using electricity generated at the Yokohama City Wind Power Plant (Hama Wing) to electrolyze
water to create low-carbon hydrogen, which is then compressed and stored.
An electrolyzer-based system would require only water for feedstock, and electricity, possibly from solar or wind, to electrolyze
, compress, and refrigerate the fuel.
The solution is perfect for remote areas which are not connected to the power grid, and can be used to electrolyze
water for many uses through power converted by PV cells," said Takatsuka.
The GH200 high-purity hydrogen generator utilizes an ion exchange membrane to electrolyze
pure water to generate hydrogen.
The standard process of making hydrogen from water through electrolysis is 50 percent efficient," he says, "but if you electrolyze
water that is already at high temperature and high pressure, that greatly improves efficiency.
Haldane proposed using electricity from windmills to electrolyze
water when the wind spun out surplus power.
PES said it completed the first phase of the contract earlier this year, "demonstrating the ability to electrolyze
water to generate hydrogen and oxygen gases at pressures exceeding 3,000 [pounds per square inch].
