A future powered by carbon-free fuel depends on our ability to harness and store energy from renewable but intermittent sources, such as solar and wind. Now, a new catalyst developed at University of Toronto Engineering gives a boost to a number of clean energy technologies that depend on producing hydrogen from water.

In addition to being a key ingredient in everything from fuel to fertilizers, hydrogen has great potential as an energy storage medium. The idea would be to use renewable electricity to produce hydrogen from water, then later reverse the process in an electrochemical fuel cell, resulting in clean power on demand.
