Scientists have proved that only water, iron, nickel and electricity can make hydrogen cheaper than before.
A team of scientists led by the Union University of Switzerland showed a cheaper and more sustainable way to make hydrogen-powered cars, which may soon be more than a novelty.
In a recent study published in Nature Communications, scientists from the University of New South Wales, Griffith University and Swinburne University of Technology in Sydney proved that by using low-cost metals such as iron and nickel as catalysts, Hydrogen is separated from the water and captured. This chemical reaction requires less energy.
Earth ’s abundant reserves of iron and nickel will replace the precious metals ruthenium, platinum, and iridium that have so far been regarded as benchmark catalysts for the “water decomposition†process.
Professor Chuan Zhao of the School of Chemistry at the University of New South Wales said that during the splitting of water, the two electrodes apply a charge to the water, which splits the hydrogen from the oxygen and uses it as energy for the fuel cell.
He said: "What we do is to coat the electrode with a catalyst to reduce energy consumption. On this catalyst, there is a tiny nano-scale interface where iron and nickel meet at the atomic level and become active sites for hydrolysis. Here, hydrogen can be separated from oxygen as fuel, and oxygen can be released as an environmentally friendly waste. "

In 2015, Professor Zhao's team invented a nickel-iron electrode to produce oxygen with record efficiency. However, Professor Zhao said that, for its part, iron and nickel are not good catalysts for hydrogen production, but their combination on the nanometer scale has led to "miracles."
"The nanoscale interface fundamentally changes the properties of these materials," he said. "Our results show that nickel-iron catalysts are as active as platinum-iron catalysts in hydrogen production."
"Another benefit is that our nickel-iron electrode can catalyze the production of hydrogen and oxygen at the same time. Therefore, we can not only use the abundant elements on the earth to reduce production costs, but also by producing one catalyst instead of two To reduce costs. "
A quick glance at today's metal prices will understand why this may be a game-changing technology. The prices of iron and nickel are USD 0.13 and USD 19.65 per kg respectively. In contrast, the prices of ruthenium, platinum and iridium are $ 11.77, $ 42.13 and $ 69.58 per gram respectively—in other words, thousands of times more expensive .
Professor Zhao said: "At present, in our fossil fuel economy, we have a huge incentive to turn to the hydrogen economy, so that we can use hydrogen as the most abundant clean energy carrier on earth."
"We have been talking about the hydrogen economy for a long time, but this time, it really seems to be coming."
Professor Zhao said that if this hydrolysis technology is further developed, one day hydrogen refueling stations will be as popular as today's gas stations, where you can use this hydrolysis technology to make hydrogen on-site to refuel fuel cell vehicles. Compared with electric vehicles powered by lithium batteries, hydrogen fuel replenishment can be completed in just a few minutes.
"We hope that our research can be used by such hydrogen stations to produce their own hydrogen, using sustainable resources such as hydropower, solar energy and these low-cost but efficient catalysts."
