Sentences with phrase «in electrolyzers»

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

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.

Not exact matches

According to John Turner, a research fellow at the National Renewable Energy Laboratory in Golden, Colo., who was not involved in the research, the discovery could reduce the need for platinum in a conventional electrolyzer.

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.

The scenarios focused on 10 to 20 years in the future, when battery and fuel cell vehicles are expected to be in much wider use, and when solar power and electrolyzers are cost competitive with the electric grid.

The test bed at NREL allows for modeling these systems and controllers in a simulated environment first and then testing with actual electrolyzer hardware and grid models.

Production capacity will be upgraded in 2016 to 5 kg per hour with the installation of a 250 kW PEM electrolyzer stack.

NREL has demonstrated this capability in a joint project with Idaho National Lab (INL) where a remote grid model running at INL controlled the 120kW PEM electrolyzer at NREL based on grid conditions.

Co-funded between the DOE Fuel Cell Technologies Office and NREL, the modular electrolyzer stack test bed (with full variable power control) coupled with hydrogen compression, storage and refueling station and (future) bio-methanation project make it unlike any system in the world.

«Evaluation of proton - conducting membranes for use in a sulfur dioxide depolarized electrolyzer.»

Power hardware - in - the - loop (PHIL) allows for high fidelity testing by simulating the unfeasible components (utility grid) with a model while simultaneously operating hardware (electrolyzer) that feeds data to the model.

Production of fuel cells, electrolyzers and hydrogen storage tanks with lower cost and higher efficiency will be enabled by the work in Research Area 2 (lead by SINTEF).

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.
