Professor Anthony O Mullane said that the potential for hydrogen renewable energy storage of chemicals was being investigated around the world.

"The Australian Government is interested in developing an hydrogen export industry to export our extensive renewable energy," said Professor O & M; Mullane of the QUT Science and Engineering Faculty.

"In principle, hydrogen offers a way to store clean energy that is needed to ensure that large-scale solar and wind farms are delivered as well as viable green energy export.

"However, current methods that use carbon sources to produce hydrogen emit emission of carbon dioxide, greenhouse gas that mitigate the benefits of using solar and renewable energy; r wind.

"The sharing of electrochemical water parts driven by electricity from renewable energy technology has been identified as one of the most sustainable methods of producing high purity hydrogen."

Professor O Mullane said that the new composite material he and PhD, Ummul Sultana had developed enabled to share hydrogen and hydrogen into hydrogen and oxygen using inexpensive and easily available components such as catalysts.

"Traditionally, catalysts for water-sharing include expensive expensive metals such as iridium oxide, oxide and platinum rubium," he said.

"An additional problem has been stable, especially for the part of the evolution of the oxygen process.

"What has been discovered is that we can use two cheaper alternatives of ground – cobalt and nickel oxide with only a fraction of gold nanoparts – to create a bi-functional fixed catalyst for water sharing and hydrogen production without emissions.

"From the point of view of the industry, it makes a lot of sense to use one catalyst material rather than two different catalysts to produce hydrogen from water."

Professor O Mullane said that the hydrogen storage could then be used in fuel cells.

"Fuel cells are a mature technology, which is already introduced in many vehicles. They use hydrogen and oxygen as a fuel to generate electricity – in essence the opposite to water sharing.

"With a lot of cheap hydrogen, we can feed fuel generated by cells back to the grid when needed during the peak demand or power of our transport system and the only thing that is dropped is water. "
