Toshiba ESS said H2One was an integrated system that uses a renewable energy source to electrolyze
water to produce hydrogen, which is then stored and used in fuel cells to provide stable delivery of 'carbon dioxide-free' electricity as well as hot water.
"We need this for storage, you have to electrolyze
water and turn it into hydrogen - and you can turn that back into electricity to fuel cells.
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.
Their answer: use renewable electricity to electrolyze
water and get hydrogen to burn for concentrated heat.
A large amount of energy is required to electrolyze
water as compared to that needed to electrolyze
The GH200 high-purity hydrogen generator utilizes an ion exchange membrane to electrolyze
pure water to generate hydrogen.
