Currently, electrolyzers (machines that split water into its constituent hydrogen and oxygen) need a catalyst, namely platinum, to run; ditto fuel cells to recombine that hydrogen with oxygen, which produces electricity.

A downside of fuel cells, however, is that they have a capital cost in the thousands of dollars per kilowatt of capacity, and the round - trip efficiency through the electrolyzer to the fuel cell and then back into current is less than 50 percent — meaning that for every two kilowatt - hours put in the bank, only one comes back out again.

Oxygen electrochemistry plays a key role in renewable energy technologies such as fuel cells and electrolyzers, but the slow kinetics of the oxygen evolution reaction (OER) limit the performance and commercialization of such devices.

Fuel Cells Electricity from any source, such as solar, wind and even coal, can be used to break up water molecules into their hydrogen and oxygen components in a device called an electrolyzer.

An alternative device, called an electrolyzer, uses solar - generated electricity to split water into clean hydrogen and oxygen, but the technique is very energy intensive and expensive.

Cobalt is both easier to engineer and less expensive than metals currently used in electrolyzers.

Additionally, installation of electrolyzer systems on electrical grids for power - to - gas applications, which integrate renewable energy, grid services and energy storage will require large - capacity, cost - effective hydrogen storage.

The Russians also did some work developing electrolyzers that can convert water, via electrolysis, into gaseous hydrogen and oxygen.

Ni also reported that with recent upgrades, their cells can transform CO2 to CO at double the rate of other CO2 - splitting electrolyzers of a comparable size, which could help them process large volumes of CO2 when scaled up.

The first half is done in an electrolyzer, which splits a water molecule into hydrogen and oxygen, and the second half in a fuel cell, which puts them back together.

It could also * potentially * be used for storage of power from intermittent sources such as wind and solar — I stress potentially, because as yet the process isn't practical due to low efficiency and the cost of electrolyzers and fuel cells.

That may be changing, well, actually, since global warming is being down played and the economy sucks, it will take longer, but cheap solar panels (nanosolar) and relatively cheap hydrogen fuel cells (Ballard power package handling units in production) with small to medium scale electrolyzers are pretty close even with not so great hydrogen storage options.
